I installed ubuntu (just ubuntu not dual boot) and i now want to get rid of it. I have my vista installer cd, but i cannot run it due to grub. I get the error message: boot from cd/dvd grub 1.5 error 22 I looked up how to delete grub, but you need to run the vista cd. It seems im in a paradox here. I cant delete grub, because i cant run win vista installer. And i cannot run win Vista installer because i can't delete grub. Please help!
