Hi there,

Ive just tried to upgrade to Windows 8 from my Windows 7 (64bit) and it all seems to install okay until it restarts and it fails with a big sad face sayign "inaccessible_boot_device".

I have a HP Envy 6-1010ea Ultrabook if that helps. Ive read on some other forums that I need to change some setting in BIOS but I have no idea how to do this. Ive also been told it would be easier to do it via a USB rather than the from the desktop..

Would appreciate the help!
