I'm an old school PC user switched to Mac 8 years ago and not familiar with XP troubleshooting. I am sort of lost here and really need some feedback. Here is what happened: I'm using a Dell Latitude laptop with XPhe. Its basically used as a typewriter. The really bad thing is that there is no network connection or floppy or CD drive on the machine. The only hardware i use with the computer is my ScanDisk thumb drive. Was working on a very important file last night. This morning I go to start work again and get Blue Screen of Death. Error code is 0x000000ED (0x80DFBE30, 0xC0000006, 0x00000000, 0x00000000). Said "Unmountable_Boot_Volume." tried safe mode but didn't work. I was hoping i could change the boot sequence to this thumb drive and do either a reinstall or system restore. However, i can't access the BIOS. I realize i may be a ***** but i would appreciate any suggestions. All i care about is that one file. I am currently reading up on the issue so as not to be clueless when/if anyone responds. Thanks!
