I installed Ubuntu 12.10 on my computer and decided to go to Windows XP. I inserted the reinstall CD and it just says:

BOOTMGR Missing, click CTRL+ALT+DEL to restart.

The same thing happens with Windows 7. I'm assuming that the BOOTMGR needs to be restored/repaired but I don't know how to do that in Ubuntu. I've read many articles that say to insert the install CD and use the command prompt but seeing as I can't even load the CD that is a problem. So basically my question is, how do I replace/reinstall the BOOTMGR through Ubuntu?

  1. Have you checked the boot priority on your Bios? Re-check if your CD drive is first on your boot.
  2. If you somehow manage to get to the Windows 7 repair console type in the following commands:

    bootrec.exe /FixMBR
    bootrec.exe /FixBoot 
    
  3. If you can boot your Ubuntu dist, you can try using a partitioning software (like disk utility), select the partition where you installed it (probably labeled System), right click the partition and mark it as boot.
