Im currently running Win7, and want to wipe the drive and install 10.10.
I have 10.10 loaded on a USB thumbdrive and it sees the device in BIOS but it only reaches a screen saying;
Unknown Filesystem grub rescue>
Ive read several results from google and a couple here where people are trying to dual boot and i assume save the data on the drive, but i dont care about doing that, and would prefer to just wipe the drive and start fresh.
What steps can i take to get the drive to a point where i can load 10.10 live and get it installed?
