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?
