So I installed XP on a partition alongside Windows 7 and I have lost the Windows 7 bootloader. I'd like to have it back, even if it means getting rid of XP, as I no longer need it. How can I accomplish this?

If you no longer need XP why don't you delete it anyway? – ChrisF Dec 26 '09 at 18:39

If you no longer need Windows XP, I would personally just do a fresh install and format as you will get rid of a lot of the "relics" that are no longer needed.

Otherwise, the easiest way to simply reinstate the Windows 7 Bootloader is to put in any Windows 7 DVD and on the first screen, choose the Repair option and then it should automatically scan for problems.

If it does not find it automatically, choose Start up repair and it should copy and reinstall the bootloader.

a fresh install and format on the whole harddrive? i would like to keep my windows 7 partition. and possibly regrow it, if possible – Chris Dec 26 '09 at 18:58
I agree and my second answer will mean you do not have to... I am just saying that in the first, it will remove all the junk and old items left over by Windows XP that you no longer need... but I agree, it is overkill if you are already using your Windows 7 a lot. – William Hilsum Dec 26 '09 at 19:13

Boot from the DVD. on the second screen (after you choose your language) go to repair your computer. then go to command prompt and type this:

bootrec /fixmbr

Press enter.

Then type this:

bootrec /fixboot

Press enter.

@ Molly7244 : Thanks a billion for your answer. I had the same problem and I got my bootloader back with these simple commands. – user64232 Jan 22 '11 at 11:30
