You I have that problem to. ONly all I have is a NTFS and recovery partition (HP pavillion 520n) it locks up on boot sometimes and I have to turn it off then back on quickly to get it to work. I tried it will an old 8 gig that I installed debian to and the same thing happens. I tried to flash the bios with a new update but the program can't find the chip.

Sigh.... A new computer would be good right about now. it seems everything hardware related that can, has gone wrong.
