The day before yesterday I was testing out a program with several system utilities built in. One of its components left my computer in a bit of a mess – no icons anywhere and other assorted woes. I had set a system restore point before I ran the program, so I thought I’d do a system restore. System restore gave me a message that it couldn’t restore my files. I decided to restore a disc image I had made a short while back. When I booted up the computer I got a message:
BOOTMGR is missing
Press Ctrl+Alt+Del to restart
I stared at it the white letters on the black background for a few minutes, while the cursor blinked back at me. After some searching (on another computer) I had some solutions.
Barring any hardware errors, here’s how to fix that error:

  • Insert your Windows Vista or Windows 7 disk into your DVD player and restart your computer.
  • The next screen you see should have the Language, Time and Currency and Keyboard boxes.
  • In the lower left side there are two options: “What to know before installing Windows” and “Repair your computer.”
  • Click on “Repair your computer”
  • Windows will then try to find the installation directory for Vista or Windows 7, depending on what you have.
  • Next up is a screen with a box called Recovery Options. Click the first option, Startup Repair.
  • You’ll see a Startup Repair box with the message “Startup Repair is checking your system for problems…”
  • When it’s done, it will prompt you to reboot. If there is more than one problem it may reboot again to continue repairing.
  • At this point, you can remove the DVD, reboot and everything should be working.

Two sites I found helpful are BOOTMGR is Missing at and cyberstorms How to fix "BOOTMGR is missing" in Windows Vista
If the method outlined above doesn't work, try Solution #2 at the cyberstorm link.
Oh, restoring the disc image went fine and all is well. All my data was backed up (somewhere other than the hard drive Windows is on) so that was one thing I didn't need to worry about. Windows Vista and Windows 7 are the only Windows operating systems where this message appears; XP users don't have to worry about this one.

I also had this problem.I had a computer full of virus so I booted the computer from a disk which was unfortunately corrupted and I formatted the whole OS files from inside the installer so that I could install the new OS from the disk but the disk was corrupted and Windows Extracting Files was stuck at 0% and after fifteen minutes also it was same and suddenly a message appeared said the disk was corrupted and it cannot proceed installation. I searched google for some way to solve the problem but nothing did. So I tried many things like to changing the boot device sequence, to run the boot menu from different drives by pressing F10 and then selecting it, Enabling the BIOS update from the BIOS settings, I tried to insert a new bootable disk which was in good condition but the same message "BOOTMGR is missing press ctrl+alt+delete" or BOOTMGR has failed press any key to continue. I then tried to restore the default settings in the BIOS by pressing F9 and then saved it by pressing F10. After spending the whole day behind this nothing happened.So at last I somehow switched off the computer with the new bootable dvd inside the drive and after and hour or two I again tried to start it with God's name and finally somehow the "Press any key to boot from CD or DVD..." appeared I quickly pressed the key and somehow the "Windows loading Files" screen came, so fortunately, there was this new disk inside the drive I re-installed the windows from the new disk again and it worked for me. But surely what was the real problem or solution I still do not know.

This document pertains to HP and Compaq desktop PCs that came with Windows 7.

The following error opens when attempting to start the PC:

BOOTMGR is missing
Press CTRL+ALT+DEL to restart the PC

If you recently installed an additional hard drive, turn off the computer and remove the drive before using the
following steps:

1. Open HP System Recovery:

CAUTION: Do not perform a system recovery! Stop at the first recovery screen.
Press the F11 key repeatedly while the computer is starting.

If you have a recovery disc, turn on the PC and insert the first recovery disc into the drive. Use the disc to enter the system recovery.

Select Microsoft Startup Repair tool and wait for repair to find and fix errors. When finished, restart the computer; even if the startup repair tool finds errors but cannot fix them.

If the error message persists, open the recovery manager screen as was done in step 1.

At the recovery manager screen, press ALT + D.

Enter the following text at the command prompt: bootrec /rebuildbcd

If bootrec displays "Add installation to boot list?", press y .
After bootrec completes successfully, the computer displays "The operation completed successfully".

To close the command prompt, enter the following text: exit

At the Recovery Manager screen, select Microsoft Startup Repair tool (again) and wait for startup
repair to find and fix errors. When finished, restart the computer.

The error should no longer open. If it does, perform a system recovery, making sure to backup
important files.

If you removed a hard drive before using these steps, replace the drive. If the error occurs again, make sure the additional hard drive is not set as an active drive. Only the main bootable drive should be set as active.

I have a Problem to starting windows. It shows that BOOTMGR missing and while i press Alt and f10 Simulationaly then it doesn't word. Then What would i have to do to restore computer?
