I had Ubuntu and Windows 7 installed, but since I never used Ubuntu and it used 130GB of space I decided to delete it. I deleted two partitions and completely wiped the one with the data. The other one - which I believe had the startup - wasn't wiped. By the way, my CD drive doesn't work.

At first I got "error: no such partition" in GRUB. Eventually I managed to put the Windows Recovery Disk on a USB stick and made it bootable using PowerISO. Windows Repair couldn't fix the problem automatically.

I then read some forums and asked somewhere else and they said to download GParted and put that on a USB stick, boot from it, and edit my partitions there. I downloaded GParted and tried to set it up the same exact way I got Windows Repair to work (with PowerISO), but it didn't work.

I formatted it as FAT, FAT32 and NTFS (but exFAT didn't work, that's the only one I haven't tried). I tried a program they recommended called Tuxboot, too, but that didn't work. I always got "error: no such partition". I've tried all the USB slots.

How can I recover the Windows 7 boot partition?

What you need to do is restore the MBR. – Simon Sheehan Dec 29 '11 at 5:07
Thank you sweet prince IT WORKED JESUS ALMIGHTY after eight hours. I googled that and followed these instructions:… and they worked. Apparently I visited that link 5 hours ago too but closed it lol. Thank you! – Jamie Dec 29 '11 at 5:29

I managed to fix it by following the instructions at SevenForums.

So basically, if you have this problem, download PowerISO, format a USB drive, click Create Bootable USB drive, select the Windows Recovery Disc (you can download it online), boot from USB, click command prompt, and do what it says there.

For me, bootsect wasn't there, so I typed in Bootrec.exe /FixBoot and then Bootrec.exe /FixMbr like a link in that link says. Then I restarted my computer and it worked.

I had to do the same thing a little while back. It's a bit harder with XP, as that tends to not like being on a USB stick. – Rob Jan 5 '12 at 16:12

I booted from recovery disc, then navigate to command prompt and enter: BootRec.exe /FixMbr

Was able to recoever the boot partition. Boot successfully.

Here's how i managed to do it. In my case the boot partition was unformatted and the bootrec gave an error saying it could not recognise the filesystem. howewer a simple format command from the recovery disk command prompt solved the issue . And i was successfully able to recover it! I have recorded the step here. Hope it helps
