There can be different causes for this problem:Invalid boot device
No boot device found
No boot device available
Unable to find boot device. Select proper boot device or insert boot media
BOOTMGR is missing. Press Ctrl+Alt+Del to restart
- Disk a have been left in a removable drive:
Usually caused by having inserted a disk in the floppy drive or the CD-ROM drive or attaching an USB flash drive. Just remove the disk from the drive, and it should be solved. More Info MS KB812492 - Trying to boot from a hard disk that is no longer recognized as boot device:
One should verify that hard disk cables are properly attached and that the hard disk is being detected properly by the system.
If having added a new hard disk, then one should make sure that the disk controller doesn't attempt to boot from the new hard disk.
If having reset the motherboard BIOS configuration, then one should check that the primary boot device is configured properly. - Boot partition is not active partition:
If having been working with partition tools (Like Disk Management or Fdisk), then one might have removed the Active Partition setting from the boot partition.- Vista - Use Windows Recovery Environment and perform a "Startup Repair".
- Win2k / XP / Win2k3 - Use Recovery Console and run fixboot
- Win9x / DOS - Use a partition configuration tool like Fdisk to set the active boot partition.
- Trying to boot from a CD / DVD to install the operating system:
Just like when booting from a hard disk, then one must ensure that the motherboard BIOS actually recognizes the CD / DVD-drive. If not then check the power- and data-cables to the CD / DVD drive.
If the motherboard BIOS recognizes the CD / DVD drive, then one must configure the boot device priority in the motherboard BIOS so the CD / DVD drive has the highest priority. This will ensure that it will not try to boot from other devices before booting from the CD / DVD drive.

I need to Start the Windows Recovery Console to reattach my Primary Hard Drive in Wink2 pc from DOS screen. Your article states to insert the "Windows Startup CD-ROM." I have all, I think, of the original disks that came from Dell with my Latitude CPt laptop, but I can't determine on which is located the 'Windows Startup' data. Do you have any Idea which of the disks this is on? Thanks, Al
Sorry I have no experience with Dell laptops or any other laptops. I recommend you find a forum or support site for Dell laptops.

I have a Dell pentium 4. A guy formatted the hard drive removing both partitions. I cannot get the computer to reinstall XP. I have tried to boot up to the internal dvd drive & an a external cd drive. I still get the drive manager missing error. I tried a new Dell reinstall operating system disc & a new Microsoft Windows XP disc. Same error message. It appears to be reading the disc but won't reinstall. Could the hard drive be bad? J.R.
I have the same problem with HP Pavilion 491.
Boot miniXP from CD and see with a program, what kind of IDE Controller you have.
After that you can start XP install from original disk, and press F6 when it is needed.
Put your floppy with the Controller driver in, install and after you can continue.
My problem is, that I need SIS 5513 Controller. I have all of the sys files, but no txtsetup.oem
i am also have the same bootmgr problem with windows 7.i tried installing the operating system again but the problem persist.how do i restore the bootmgr?
You can repair the bootmgr by performing the startup recovery 3 times using the vista/windows 7 install disk after the third attempt at startup recovery, vista/windows 7 will replace the bootmgr and you should be good to go.
You need to get a fill file for the hard drive from Dell. Dell is specific to Dell and you cannot just reformat and expect to be able to reinstall a windows program. You may be able to call Dell and see if they can tell you where for find the file you need to fill the drive with 0s so you can reinstall Windows. The file will have to come from Dell because it will have Dell information imbeded into the file. Good Luck
