How to fix the 'BOOTMGR is Missing' and 'Couldn't Find BOOTMGR' errors that sometimes appear during startup in Windows 10, 8, 7, or Vista. Mar 16, 2011 Windows 7 Forums is the largest help and support community, providing friendly help and advice for Microsoft Windows 7 Computers such as Dell, HP, Acer, Asus or a custom build. Hi, I am trying to install windows 7 off of my usb harddrive and I get a 'bootmgr is missing, press ctrl+alt+del to restart', it works on any other computer but the one.
- Recently a friend of mine had some problems with his pc and wanted windows 7 on it. The problems were fixed, formatted the HDD and tried installing windows using a bootable USB. Now, when the PC starts and i selected the USB from the boot menu, it says: BOOTMGR is missing, press Ctrl+Alt+Delete.

Yesterday i has installing some widgets to my desktop and after i have restarted the laptop windows coudn't start.it says bootmgr is missing.

i have a sony vaio laptop with no partitions no nothing just a hard disk with pre-installed windows 7 64 bit home premium. Yesterday i has installing some widgets to my desktop and after i have restarted the laptop windows coudn't start..it says bootmgr is missing. I tryied to use the recovery tools of vaio but the only option is toformat everything and install again windows 7 but i dont want this option. I have tried almost everything finding on net many answers about this problem but none of them it worked to me. I downloaded a bootable disk to repair the windows i tryied to do it manually from the prompt command but nothing..Its very strange though when i open the vaio recovery tools i can save all my files to an external drive but it appears a partition d: which before didnt exist
and have one folder called boot and inside contains a file called bootmgr. I would like if somebody have any idea what to do cause i have this laptop 1 month it it drives me crazy when i am thinking that i need to format everything
thanks
Be sure you are actually booting to the USB drive if using a USB boot disk.
Check Dell's on-line documentation, diagnostics, and ask in their forums about known issues. Dell should have troubleshooting methods on-line to help with such issues.

References to Vista also apply to Windows 7.
See if these help - boot with a Windows USB drive (repair drive ok) and issue
these from the Command Prompt and hit ENTER after each.
Setup/Setting (BIOS/CMOS) often F2 as you boot so watch the screen - set
to USB drive first in the boot order - remember to set back when done.
(Some use F12 or other keys for a one time boot order change.)

If those help then run StartUp Repair THREE times - run once and then
reboot and run again - repeat. (Use a Windows 7 USB drive.)

Using EasyBCD often works when other methods do not. <-- if Bootrec did not help use this.
