I used to have Ubuntu dual-booted with my Windows 7 and I just recently removed it because I wanted this computer to run just Windows 7 only. My only problem is that I can't run Windows 7 when I remove Ubuntu because the GRUB Loader is in the way. I know there's a fix of some sort about typing in "fixmbr" but I don't really know how to do so(I've tried already...many times.) So, I wanted to know if someone can give me like a guideline on how to fix this problem in detail if at all possible. Thank you in advance.
