I had a dual-boot setup with Windows 7 and Windows Vista. I used Easus Partition Manager and shrank my Windows 7 partition. In the empty space, I installed Linux Mint. I decided I didn't want it anymore, I simply deleted the Linux Mint partition. Now when I boot, all I get is this:
GRUB loading. error: no such partition grub rescue>
I don't have my Windows 7 install disk because it was pre-installed.
