I went to Ubuntu a few years ago, full installation, and now I want to go back to Vista. I've tried formatting the entire HDD to NTFS, no go. Even if I could install a dual boot with vista I'd be happy. Problem with the dual boot, mostly all the instructions have you install vista first, then ubuntu. I know I need to fix my grub. Also my step father only burnt the Vista installation discs, and kept the originals, So I don't have diskpart.exe to fix my mbr boot to install vista. If you need more info to help just ask. I'm on 14.04.3 LTS Ubuntu 32 bit.
