Whenever I start a computer and it goes past the first win xp screen. A blue screen pops up stating: Unmountable_Boot_Volume ***Stop: 0x000000ED (0x8IFFI600,0xC000009C,0X00000000,0x00000000) Recently I have been experiencing this problem constantly after a couple weeks of using win xp. I' am wondering if anybody knows how to stop this problem because quite frankly it is getting anoying since I have to format constantly. Sometimes it is possible to get past this problem but it requires the computer being constantly re-booted but I have tried this method once again and no luck. If more information is required please say so. Any help would be appreciated.
