Installing Ubuntu on a Pre-Installed UEFI Supported Windows 8 system
I just installed 12.10 on my pc alongside windows 8. I followed all the direction with the windows installer but when i try to boot Ubuntu it says that it cant run it because a file is missing.
wubildr.mbr
and it's not missing or corrupt (even if the message says so). Wubi doesn't work with any preinstalled Windows 8 computers. There's a duplicate question somewhere about that, but basically you have to do a normal install. – bcbc Jan 20 '13 at 23:07
