HP Spectre Touchsmart throws this code on boot and hangs. I enabled Legacy support and booted to Linux and can copy files to a fat32 partition. I put the drive in another Windows machine, on boot, post states hard drive is incompatible. If the drive has gone bad, why can I copy off it in Linux? This is a Win 8.1 machine. Is the (3fo) code a failing hard drive or motherboard? Thanks!
