I have an old Dell Dimension 2400 with Windows XP Home Edition. I am trying to get some data off it. When I start it goes to the black screen with the choices of normal mode, safe mode, etc., all of which show Windows trying to boot but ending up with a blue screen with the message "Unmountable_Boot_Volume" and the following stop codes: 0x000000ED (0x81B4F5F0,0xC0000006,0x00000000,0x00000000). I have tried booting with the Windows XP disk in the CD drive, but same result. I have seen lots of messages to get to the Recovery Console when I get the Welcome to setup message, but I never get there, always straight back to the blue screen. Neither Microsoft's nor Dell's support sites address this.
Any ideas?
