Restore boot manager when it is missing or compressed

Windows Vista includes a new Boot Manager (BootMgr) that replaces the old NT Loader (Ntldr).

If you don't have the install DVD, then go ask friends/family/work whether they have a disc you can borrow. If your computer cannot boot from a DVD, then you can use another computer to Create a Windows Vista/7 Recovery disk on an USB stick.
Boot Manager is missing
If the boot partition no longer can be found, then Vista will display the following error:

BOOTMGR is missing. Press Ctrl+Alt+Del to restart

The Windows Boot Configuration Data file is missing required information

More Info MS KB927391
More Info MS KB2622803

Check points for fixing missing boot-manager:
Boot Manager is compressed
If by accident having compressed the entire boot partition, then Vista will display the following error:

BOOTMGR is compressed. Press Ctrl+Alt+Del to restart

Check points for fixing compressed boot-manager:
  • Boot into Windows Recovery Environment (WinRE) and perform a "Startup Repair".
  • If the above doesn't solve the problem then boot into WinRE again, but when selecting the Vista-installation, then press "Load Drivers" (Instead of "Next") and use the mini Windows Explorer to right-click the boot-drive and deselect "Compress this Drive" and choose Apply to sub-folders and files.
  • If that also fails then boot into WinRE again, and go to the "Command Prompt" and execute these commands:
    • compact /U C:\bootmgr
    • compact /U C:\ntldr
  • If you for some strange reason have lost your Vista DVD, then you can also use a Windows 2000 / XP install CD and enter the recovery console instead and execute the following commands:
    • attrib -c c:\bootmgr
    • attrib -c c:\ntldr

    The problem with the final option is that -c is not a supported swith with the attrib command, or am I missing something?

    The problem with the final option is that -c is not a supported swith with the attrib command, or am I missing something?

    Sorry for the confusion, didn't know that "attrib -c" was only available in the old Recovery Console. Have changed the commands to use the compact.exe tool.

  3. hi these options are not possible if you have compressed the drive, as you need the vista dvd to get to the command prompt to get to recovery console.

  5. I got a easy way for everybody, check this:
    go thru the usual steps...
    reboot, push open the dvd drive, load OS Vista CD/DVD, before the ridiculed bootmgr compressed shows, shutdown, boot from the dvd, let the installer do it's job.
    when reach choice "install now" choose "repair the pc" instead.
    In the System Recovery Options dialog box, choose the drive of your Windows installation and click Next.
    click Startup Repair.
    Just click "load drives"since you know the answer about "repair"....nothing wrong..)=:
    see that??, you're inside your HD!! I assuming that from here everybody knows what to do, if not, that what follow:
    Browse for your "C" Drive, right click properties and fellas, reverse what you did, exit, reboot and get a real cold Corona
    send me a note, I need some help on Server 2008 config

    Thanks snakefoot ...good advice

  7. Night Flyer says:

    Everybody keep saying boot from the Vista DVD and then click repair. 6 times this month, I have lost the bootmgr file and when I try to do a repair, I get the message that no Windows operating system can be found.
    I put the disk in another computer and checked the properties and it shows that the entire disk is completely used up, but there are no files that can be read. When I try to see any files, I get the Message that I do not have access to this drive. Now what.
    This is ongoing with me. I have had the problem on WD and Seagate and Maxtor drives. Tried them all. No viruses found, etc.
    Please help.

    If you cannot get your computer to boot from the install disk, then you should visit a computer repair shop.

  11. redzakk says:

    I am doing everything you have listed here, but it still does not work.

    1) compact /U C:\bootmgr --> the command "compact" is written wrong or was not found ???

    2) attrib -c c:|bootmgr --> doesn´t work either

    3) getting into my C: HD and rightclicking on bootmgr --> what shall I reverse? I haven´t done any change on my PC... well not me, I do not know, maybe any program?

    Please, what happens if I overwrite (install) a new version over the old one? Do I losse all my data?

    I am really enthisiasmated about all these computer champions here, really ;-) I am impressed!!! best regards from redzakk

  12. redzakk says:

    Hey Jose, and you other cracks. It worked :-) I am happy, very happy :-)

  18. Filip Kofron says:

    Hello everyone,

    I had these problems too. I was unable to fix that, but ntldr and bootmgr were without the compress flag. So I was looking for another reason and finally i found file "grldr", it shows like grub in hex editor :-O. So my problem was solved by attrib -c grldr under XP recovery console.

  19. SneakyPeakey says:

    i have had the same problem with the disk drive not showing up in the 'repair computer' section, clicked on next and went into command prompt, went on 'diskpart' and set the disk a 'active' it messed up wen i was installin mac osx as a dual boot.

  20. Kamee says:

    if your still having the Problem with
    (*BOOTMGR is compressed. Press Ctrl+Alt+Del to restart*)

    Then you have Two ways to Fix that.

    (No 1 Way)
    Boot from the Vista DVD.
    Click 'Repair my Computer'
    At the prompt to select your OS installation, click the button that says 'Load Drivers'. This should bring up a explorer-style drive browser.

    Then just right-click on the drive you tried to compress, and deselect 'Compress this Drive', which should still be ticked on. Hit apply, and apply to subfolders/files.


    If that don't work for you then!

    (The Second way)
    If the previous method does not resolve the problem, you can rebuild the BCD store by using the Bootrec.exe tool in the Windows Recovery Environment. To do this, follow these steps:

    - Get your Vista installation DVD and pop it into your drive.
    - Then restart your computer.
    - Press a key when you are prompted.
    - Select a language, a time, a currency, and a keyboard or another input method, and then click Next
    - Click Repair your computer
    - Click the operating system that you want to repair, and then click Next
    - In the System Recovery Options dialog box, click Command Prompt
    - Type bootrec /rebuildbcd and then press ENTER

    • If Bootrec runs successfully, it will present you with the installation path of a Windows directory. To add the entry to the BCD store, type Yes . A confirmation message appears that indicates the entry was added successfully.

    • If Bootrec cannot locate any missing Windows installations, you must remove the BCD store, and then you must re-create it. To do this, type the following commands in the order shown below: (Remember to press ENTER after each command)

    bcdedit /export C:\BCD_Backup

    ren c:\boot\bcd bcd.old

    bootrec /rebuildbcd

    - Restart the computer.

  23. fashiondesign_guru says:

    everything sounds good except my laptop doesn't have a working cdrom.

    is there a way to boot or do anything from another pc using usb connection? all I need is to boot the pc because there's a recovery section or partition or a locked drive inside.. which is weird because I can't access to it or even see it from bios. actually this all started when I was using that recovery thing and it was restoring the pc to the factory settings and reformatting vista while saving my data in a seperate folder to which I was going to be able to access after the reformat, but little after it started we lost power for a few secs and when I started the computer, I started getting bootmgr missing thing. is there a way to boot from or do any recovery using another pc?

  24. Eduardo says:

    Jose Plunktt, great job, you save my day!!!

    Thanks very much Snakefoot!. I was able to reboot my laptop.
    Windows did take a while to restore but it works. I just keep refreshing window explorer to monitor the decompress progress.
    Your instruction is pretty good.

    HELP!!!!! computer was acting a little cooky (I wasn't able to do anything that required administrator) so I went and bought the new vista disk...popped it in the cd drive and went through the motions to reinstall it. It got about halfway through and then said it couldnt continue and restarted. When I brought it back up and tried to go through it again, it had wiped my entire computer...drivers included!! Now Im stuck! I downloaded the drivers off my home pc and put them on a harddrive and I dont know what to do from here. My computer just goes to the bootmgr is missing. Please help! I cant go to a computer husband is military and we are stationed on a tiny island!

  31. Spitfire says:

    I had hope that I could fix my comp with your help
    First off, I had this problem the day before I have a and athlon 64 x2 processor 4000+, 320 gb hard drive, 1 gb ddr2 dual channel and a nvidia geforce 6150 SE.

    I upgraded into a xfx geforce 9800 gt and my power supply from 300 to 620. I installed the game prototype and was playing it without any problem. The next day I tried to play the game but was late for school so I just unplugged the comp. I went back and the comp responded with a black screen and a white movable mouse nothing else.

    I went to safe mode with networking and succesfully got in. I couldn't find any solution so I tried to restore the system not to it's factory form but a restore that would save my files. It had been 1 hr and it was still at 0% and so I turn the of off.

    When I turned it back on I got an error "bootmgr is missing" and to press ctrl + alt + del so I searched for a solution and tried everything in here before. The big problem is that when I click repair computer and go to the section where I select drives, there's no drives available, which makes the system recovery tools useless. When I do load drivers a brower opens but could not use any driver., I could see my C drive and could see my files in a backup I tried the right click C drive but compress is already unchecked I really need my computer as all my projects, family pics and videos are saved in it.

    This problem is been around for too long we need a permanent fix!!
    I beg all of you to Please help me!!!!!!

    This is because the Windows installation has become so damaged that it is no longer recognized as a Windows installation. If the "Startup Repair" doesn't work, then I guess your only option is to reinstall Windows Vista again from scratch. Though I would probably perform a diagnostic of the hard disk and the RAM modules first.

    You need to make the computer boot from the Vista install disk since your computer can no longer boot from the hard disk. You can then perform the Vista installation from the Vista install disk instead. See How to Set BIOS to Boot from CDROM to make your computer boot from the Vista install disk.

  34. Spitfire says:

    If that is the case, is there any way that u can at least save the filed that I have in the C: drive? When I click load drivers I could still see that it made a backup for all of it. It's 163 GB worth...

  35. Snakefoot says:

    Installing Windows doesn't mean that it erases the C-drive, only the Windows directory. If you want to backup your files before reinstalling Windows, then you can use a recovery disk with a backup utility, or take out the harddisk and connect it to another computer for backup.

  36. Tired says:

    I bought this HP desktop at a computer store and no recovery disk came with it. Now I keep getting this message: "bootmngr" missing. I don't have a disk to boot it. Where can I download a boot disk for Vista? Do I just burn it to a CD?

  37. David says:

    YES! Finally some info that actually helped! I've been working on this computer for a while now.. Finally gave up and sent it in to Dell.. What do they do? Send it back in the same freakin condition it left in! So I decided to work on it again, and this was what I needed. Thank you so much for your help Kamee. :D

  38. Yohan says:

    Can't get anything to work, yesterday I needed some hard drive so I looked into compressing my C: drive. It commenced but I looked at the estimated time, and thought it was too long so I canceled, so I go on the rest of my day as usual, then when I finished installing a file, that required a restart,"BOOTMGR is compressed" I have searched around for a solution I had one that I believed would work, but it was the process of creating a new boot file manually, unsuccessful because boot files already existed, I'm currently running Windows Vista Ultimate, have lost the boot disc and key, so I'm using a repair disc from Neosmart Tech.

    Any help would be appreciated.

  39. sun it says:

    hai, its work well for me thanks lot....

  40. dtrain says:

    i did the exact same thing as you except for the part for the “estimated time”, i was in a rush and had to step out so i just press yes. never the less i’m sure you can do a search for a soft copy of the recovery disk somewhere on the net.

    in this case where Alt+Ctrl+Del is not working, what else can i do to uncompress my bootmgr.
    PLz Help..

  55. eLHAMiiD_ says:

    Guys; try to be very simple when giving assistance; not every one understands those rather very fast answers you give.

    SOLUTION TO THE "BOOTMGR is compressed press CTRL+ALT+DEL" problem

    1. INSERT your VISTA DVD in your laptop/PC
    2. Power ON your laptop/PC
    3. BOOT from VISTA DVD ---->make sure your laptop/PC
    is set to boot from DVD/CDROM first or when u see the
    message that says "PRESS ANY KEY TO BOOT FROM
    DVD/CD" just hit any key and the next steps will be
    4. Click "INSTALL"
    5. Choose "LANGUAGE" of your choice
    6. Click "REPAIR"
    7. Before you click "NEXT" click on "UPLOAD DRIVERS"
    8. in the "OPEN" dialog box that appears on the left side
    click "MY COMPUTER" then find your "LOCAL DRIVE C:"
    and "RIGHT CLICK IT" then select "PROPERTIES"
    9. there are two "CHECK BOXES" on the "C: properties
    dialogue box", so "UNCHECK" the one that says
    "COMPRESSED" if its checked
    10. hit the "APPLY" button, wait as this takes a less than a
    minutes or so depending on your computers
    PROCESSOR/RAM, please be patient!!!
    11. U can now hit the "OK" button; and VOILA, go have fun

    I have the same problem when yesterdya try to compressed drive C. I'm using dual boot with Ubuntu, so I'm able to look for solution using it. Gladly, I've found this article but I haven't try it yet.

  78. newtricious4u says:

    Just wanted to give much thanx to eLHAMiiD_ for his clear step by step instructions. I have a toshiba satelite with windows 7. I had begun to compress my C drive, then cancelled and shut down, and was freaking out when i tried to use it again and couldnt get past the restarts due to bootmgr being compressed. Was so scared that my computer was gonna be wiped out of my important documents or just not functional at all. Luckily i was able to google solutions on my phone, borrowed a copy of windows 7 from someone (i didnt have one cause my laptop came preloaded, so thats a note for other people wondering, you can use any copy of a windows OS even if its not the one specifically installed on ur comp), followed elhamiids instructions, and was able to undo the compression on the C drive and my laptop was unfazed. No files lost or changed. Yay.

    Windows should really show a warning box about the booting being effected before anyone can proceed, or they should adjust the compression option so that it never tampers with the system booting to begin with because i had no idea this problem existed or could happen just by trying to save hard disk space. Anyways, thanx again to this forum. Sooo thankful. Never trying that compression ish again.

    Yayyyyy!!! Thanks Jose!!! It worked! and it is easy too!! thanks!

    Heres the start!
    Windows updates were not installing (190 important)
    "has not been used online for a while"

    BOTH the c-drive and e-drive completely full,

    Unable to remove the programs like nero, ms office & photoshop taking up all the space as there was some "runtime error"

    unable to fix this due to Internet explorer being corrupt or hidden or something??

    Cannot install/update IE without updating my windows or visa versa.

    YEAH also cannot workout what the guy who owned this laptop before me has done with this thing as its running vista ultimate but the laptop has a genuine XP sticker underneath.

    "ME stupidly compressed the drives to save disk space (which mind you freed like 1gb) what a joke : /


    HERES ONE FOR YOU! Tell me what you do to a dell that does not have a working cd/dvd drive,
    No instillation or recovery cd's,
    No F8, F11 hold this, tap that, shift, ctrl, alt whatever to get to any advanced boot options.. i have tried them all!
    "boot the recovery/set up discs?" Ye no warries

    You have F2 -bios setup (will not help) dont bother mentioning boot sequence or loading defaults, please your wasting your time with that one!

    And F12 - Boot menu! internal HDD, cd/dvd drive, onboard NIC, bios setup and diagnostics.. Does nothing for me!


    Now if you read this properly, My dog did not eat my cd's they prob did come with the computer when it was first purchased.
    Some people buy second hand cars without the "drivers manual" in the glove box!
    These things happen.

    I just hope that someone out there (with some knowledge) will read this and use their time to actually input something relevant for the problem above.

    Dont embarrass yourself by leaving yet another pointless comment stating something we have all read 2000+ times before.

    Much appreciated. xx

  88. Oliver says:

    i have had the same problem as everyone on here, i couldn't find any possible way but i did have a bit of luck, i have a 250GB HD split into 3 partitions. a 111GB section, a 108GB and the other 31GB was the 3rd one. the 111GB held my compressed Bootmgr and the other 108GB held some program files and one held absolutly nothing i used the 31GB to install another Windows OS i am using windows 7 all the way so i install it onto the small section and i then signed into the fresh install and right-clicked on the drive with my main OS on it and then told it to Uncompress the drive. i then restated the machine and i can now access my computer like nothing had happened to it. hope this is helpful to someone. if anyone needs any help with again please ask:

    eLHAMiiD you are a God send! I did the foolish thing and started compressing files on my hard drive not even thinking about how that would possibly screw up my startup for Windows 7. It looks like your solution is going to save me. Thank you 100 times over!

    You can also use CHKDSK to scan for and repair system errors.this decompresses the necessary files instead of the whole drive.

    I have pressed the three keys many times however, nothing changes it always brings up the message. My netbook does not have a disc drive and when i try to go to system recovery it will not let me. May someone please tell me what i can do to fix this??

  104. Angel says:

    Yes, go to Ubuntu's website. Download their Operating System and on that same page download their Universal USB Installer or download UNetbootin.
    You'll have to do this on a seperate computer. When the Operating System image (.iso) is done, run the Universal USB Installer or UNetbootin and load the image file and save/load it onto the a USB Flash drive within that wizard on the same page. Check the Format USB to ensure that it loads on the flash drive without any problems. When it's finished then plug it into your computer that has the boot manager corruption/compression and install Ubuntu. After that you can download VM firm or whatever it's called, just look for VM and it should pop up. It's a virtual windows system. Then download a Windows Operating system from a torrent site or a friend and save it to the computer. Then upgrade or fresh install Windows on that drive and you can choose to keep Ubuntu or freshly install Windows and viola! That's the only way it can world with your problem.

    hi there

    i run a samsung r530 laptop with windows 7. recently i partitioned my drive into a C: drive, holding the windows 7, and the D: drive, holding Linux Ubuntu. after i had done this i restarted the laptop but it went on a loop. i have since resolved that problem, it had turned out Ubuntu was conflicting with windows, by removing Linux altogether. in the process windows 7 was copied onto the linux partition. i load my original windows and deleted the copy of it. i restarted my computer and it came up with "BOOTMGR is missing". i did not get an install disk with my laptop so i am unsure of what to do. i have also tried pressing f4 during boot for recovery mode but it proceeds to "BOOTMGR is missing". please help.

  113. RobMoore says:

    I had just restored this hard disk from a ghost image made from another laptop that was setup exactly the same way. a Dell Latitude E6510 with windows 7 pro. When I tried to boot to the OS, I would get nothing on the screen except a minus sign in the upper left corner. I booted from the windows 7 install dvd. It took about 10 minutes to load the first time. I believe because it was looking for a active windows partition. After i choose the language and locations, I selected the repair option link in the lower left hand of the screen. It did not find my windows installation. I clicked next anyway. and choose the repair option. It took less than 2 minutes to run. i clicked the details link to see what it found, missing mbr. When I rebooted the computer same thing, minus sign and nothing else. I then booted from a windows 7 pe usb stick I had made a month ago. Opened a command window and did a bootrec /RebuildBcd and bootrec /FixMbr then bootrec /FixBoot. when I rebooted, I was presented with the Boot Mgr Missing Press Alt+Clt+del to restart message. I booted back into the win pe usb stick, right clicked on my computer, selected manage, went to storage, found the hard drive, right click on it and made it the active partition. rebooted the computer and still had that nasty message.
    I rebooted and went back into the BIOS, and in the storage options, change it from ATA to RAID, I changed it to raid because thats where it was earlier and i did not think it was right so I change it.
    When I rebooted, Windows 7 Pro loaded and I am now able to use it.

    I hope this helps

  116. Ramon Leon says:

    I have the Boot Manager Compressed sign on my Asus lap top, I did the mistake of defragmenting and cleaning the c-drive on my computer to save space and when I turned it off and back on, the ionfamous sign, Boot Manager is Compressed. What can I do? I does not let me boot from any where, all I get is the signs ante mentioned, I've tried to boot with a new Windows 7 disc, with a new XP and nothing, the screen always cames back to Boot Mngr Compressed, press control, alt, delete to re-start, yet, it goes back to square one, the same message. Could somebody out there help, please, in sort of plain English, not complicated computer language that leaves people like when you go to a doctor or try to read a med prescription and all you get is a bunch of Greek-Cientific words. Thank you.

  130. Insert the installation DVD in your system and start the PC above->Click Repair your computer->Then click on Load Driver->Go to Computer->Right click on the partition your installation previously compressed> Properties->Then uncheck "Compress drive to increase space available". Then close all windows to restart the computer.. By using these steps to resolve this problem..

    how can i repair my computer (error message: boot mgr is missing) if the DVD ROM won't read the installation DVD?

    plzz help… tnx

  133. AF says:

    I have tried and tried to revive the BOOTMGR but nothing comes of my effort. It just keeps cycling. There are many promises made but none of them operate to remove this error message.
    I did realize that to make any operation work, you first need a key or action that will start up the repair (from the CD or USB).
    Without this key, the CD or USB software will not start up. In my case as in perhaps all other cases, the screen is immobile and nothing will channge that fact.
    Whom has that key? Only the 'Shadow'' knows.

  134. mikin says:

    hi everybody i m going to solve ur all the problems of bootmgr is missing..

    first of all when u r turning on ur laptop or pc the erroe comes that bootmgr is missing press restart.

    m going to solve this problem

    plz cooperate me,
    first of all plzz insert cd/dvd of win 7 or vista
    boot it
    select command promoted.
    in that wright this commands:
    compact /U C:\bootmgr
    compact /U C:\ntldr

    If you for some strange reason have lost your Vista DVD, then you can also use a Windows 2000 / XP install CD and enter the recovery console instead and execute the following commands:

    attrib -c c:\bootmgr
    attrib -c c:\ntldr
    it will really wprk but u have to do this with confident.
    thank u.

    mikin from india....

  135. mattburnin says:

    Fastest solution - fixed in 15min

    1. Download Active@ Boot Disc, and burn iso file to the disc.
    2. Run Active@ Boot Disc
    3. Open My Computer > Properties >> Untick - compress this drive to save disc space
    4. Remove Active@ Boot Disc
    5. Reboot normally.

    Once you've done that, reboot after removing active boot disc cd.
    Your computer will boot normally.

    That's it. ENJOY

    "If the above doesn't solve the problem then boot into WinRE again, but when selecting the Vista-installation, then press "Load Drivers" (Instead of "Next") and use the mini Windows Explorer to right-click the boot-drive and deselect "Compress this Drive" and choose Apply to sub-folders and files.""
