windows 7 - Why do I get a GRUB error after deleting the Linux partition?


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.



Answer



I do not have any MS operating system so I could not try this myself, from this page on the windows 7 forums - though - it seems like the startup repair utility (SRU) is also included in OEM distros of the system.


My understanding of that page is that you can then boot, with the help of a liveCD or usb drive into your existing windows 7 and from there run the SRU. If my understanding is correct, then you can most probably boot your system from the linux installation CD you originally used to install linux or by means of a dedicated tool, like the Super Grub Disk. Two scenarios that might fit your bill seem to be this and this.


Another less elegant solution would be to repair Grub [the Super Grub Disk comes in help in this scenario too] and let GRUB launch Windows 7 for you.
