I have a new HP laptop with Windows 8-32bit. I did not understand why the download for any win8 machine should be the 64bit choice. So before getting started, I have both 32 and 64 burned to disks and I have tried both. I have been right through the install, but after rebbot, when I get the OS selection page, Ubuntu will not load. The windows boot manager gives me 0xc000007b error, but I have checked the disks for errors and none are found. Has anyone else had this problem? Any solution available?
