I have a Dell Inspiron 531 that was dual-booted with Windows Vista in my main partition and Ubuntu in a secondary volume. I was using the Grub Loader as my boot device. I was trying to extend my main partition and accidentally formatted the volume that I was shrinking which was the volume containing the Ubuntu and the Grub Loader. I have about 150 gigs of videos, music, games, and apps on the Windows partition and don't want to lose them.
So I didn't think anything of it and turned it off. Now I can't boot into Windows and I don't really want to use Ubuntu anymore. I tried reinstalling Grub off of the Ubuntu installation disk however the disk refuses to load. I tried upgrading Vista from the former Vista in hopes of getting the Windows boot device installed. However, it says I have to be in Windows in order to upgrade it and I can't get into windows without the boot.
Any help would be greatfully appreciated.
