Hey, first-timer here. Overnight my laptop was left to update itself as usuall, but when I got to it this morning I found it repeatedly flashing a BSOD with the error: UNMOUNTABLE_BOOT_VOLUME I have attempted countless boots into safe mode, all throw the same BSOD at me. My machine is an HP Pavillion ze4900 model laptop running WinXP Home (well.. was). I've tried a some "common remedies" but none seems to be effective at all.. Does anyone have an idea on how to recover from this, or is my laptop to hence-forth be known as a brick. (If any solutions involve removing the HDD, you will need to explain in detail as I have not seen anything obvious on the underside) Many thanks!
