Once it fails, i have no other options but to restart into Snow again. Anyone else having this issue? Havent found a thread yet on it but nothing is working. I have a MBP 2010 2.53ghz.
If anyone else has this issue, its a problem with Parallels and Bootcamp if you have another partition for windows. I didn't use mine anyway so i used bootcamp assistant to delete the windows partition and everything went ok.
