How to fix: "Bootmgr is missing, Press Ctrl+Alt+Del to reboot" | Knowledge Base. After restoring a partition backup of my Windows 7 system drive (it stopped working just two days after I setup the backup!!) I got the ominous error: "Bootmgr is missing, Press Ctrl+Alt+Del to reboot" Apparantly this happens rather often. I first tried the bootrec.exe command line switches to now avail. I then decided to start over, restore the backup again, and then I used my Windows Repair Disc (you need to create this while your Windows is still working) to fix this issue. I suppose the Windows 7 installation disk offers the same features but I haven't tried it, so I can't confirm if it offers the same repair options. So here's what I did: Make sure you have only the target & backup drives attached. I hope that helps! Bootmgr missing after restore | Knowledge Base.
New SSD and Bootmgr problem | Knowledge Base. Windows 7 bootmgr is missing HELP!!!!!!!!!!!!!!!!!!!!! Fixing "BOOTMGR is missing" Error While Trying to Boot Windows 7 or Vista. If your Windows 7 or Vista computer has encountered the dreaded “BOOTMGR is missing” error, you aren’t alone. If the problem isn’t hardware related you can fix it with relative ease as long as you have a Windows DVD handy. If you don’t have one, you can create a Windows Vista repair disk using our guide. Boot off the Windows Vista DVD and then click Next at the first prompt: You should see a link in the lower left-hand side for “Repair your computer” The installation process will attempt to find your Vista installation directory. Click the first link for “Startup Repair” The installation process will repair the system, and then prompt for you to reboot. Alternatively you could have chosen the Command Prompt option instead, and use the following command to fix the boot options only: bootrec /fixboot At this point you should be able to reboot your computer, remove the DVD and everything should be working.
