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?

  • Some clarifications need here. Can you boot into Ubuntu now ? Have you used the same windows CD for installing in your system or somewhere before ? As i remember "bootmgr missing" error is because of the improper boot priority of the device. If you set proper boot device you can boot into your system. – learner Mar 04 '13 at 02:32
  • Yes, I can boot into ubuntu. I have used the same windows CD before on this computer. And it's not that I can't boot into windows, it's that I can't install it. @learner – Sr. Iggs Mar 04 '13 at 03:20
  • This is a question about installing Windows, not Ubuntu. I'm flagging this for migration on SuperUser. – Danatela Mar 20 '14 at 04:14
  • If you're trying to get Ubuntu and Windows to both be bootable, I think the solutions at [How can I repair grub? ...](http://askubuntu.com/q/88384) may help (even if Ubuntu boots now). Unless you installed Ubuntu with Wubi--then please edit your question with more details about how you installed Ubuntu. If you want to *just* get Windows working (removing Ubuntu), see [How to remove Ubuntu and put Windows back on?](http://askubuntu.com/q/133533). The parts there that explain how to put the Windows boot loader back may fix this too (do that so Windows boots, then repair GRUB so both will boot). – Eliah Kagan Mar 21 '14 at 03:44

  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.

  • 1. The CD drive is first. 2. That's what I would do /if/ I could get into the Windows 7 repair console. 3. Installed what? Windows? Because windows isn't installed. Only Ubuntu. – Sr. Iggs Mar 05 '13 at 20:35
