Gateway Tablet, BSOD unmountable_boot_volume

Question

1. CMOS does properly detect drive.2. XP boots far enough to ask for normal/safe mode3. Windows logo appears for a minute, then:4. Gets BSOD: [UNMOUNTABLE_BOOT_VOLUME], then5. I Boot from XP CD, Recovery option "R" (or install)6. Then I get that there are no hard drives installed7. It can go looping like this endlessly.
