Hello, for a long time now i've been messing with my hard-drive and the EFI, GUID thingy. I've been trying to successfully install windows with a working sound driver but it never works and I never hear sound on my copy of Windows. In the process I might have messed around with the EFI or something and now my MacBook is stuck on a small partition and won't let me change it, it's stuck at "Preparing to partition disk" and doesn't change from there. There is also a disk0s1 that is refusing to be deleted, i've re-installed os x and had no change. I just want it fresh again so I can try install windows again with sound.
