Palos 0 Posted February 8, 2002 Clouds of weirdness gathered above my house yesterday The previous evening I shut down the PC with no error messages. Last evening, tried to boot normally, but got a BSOD with the "UNMOUNTABLE_BOOT_DEVICE" message. My C: drive is NTFS, the others (D-H) are FAT32, I and J CDR/DVD drives. I am running the VIA PCI patch, on a 8KHA DDR mobo (no raid). Did a safe mode, and I noticed the BSOD came after trying to load the mcp.sys driver. Booted from my XP CD, selected to ®epair the existing installation, got to a pseudo-DOS prompt and decided to run the "Fix Boot" command. Rewrote the Boot sector, and the PC boots w/o problems since then. What could have caused this? --------------------------------------------------- Do NOT download the 23.11 drivers from the Microsoft Update site, they resulted in a repetitive BSOD/Infinite loop blues. Instead I dloaded the new 27.10 (www.reactorcritical.com), and didn't experience ANY problems so far. Share this post Link to post
