I have a friends PC which has just started giving BSOD 0x000000ED (UNMOUNTABLE_BOOT_VOLUME) every time he starts it (any option chosen gives this e.g. Normal Mode, Safe Mode, Last Known Good etc.).
The PC is a 1 year old Dell and no new hardware has been installed recently. It was working fine yesterday and the only thing to happen to the PC today was that a plug n play PSP was plugged in. Probably not related, but thought I'd mention it.
Anyway, Dell diagnostic software says the HD is ok and doesn't report anything else on its very long diagnostic checks.
I've read all the MS support articles on why this code could happen and I don't think most apply - we haven't just upgraded or installed the OS, the HD hasn't been changed and the cabling is as was provided by Dell. Any idea why this could suddenly happen?
I just wanted your advice - I plan to proceed with a Recovery Console boot and chkdsk /r (or should that be /x /r ?). If that doesn't work I was gonna do a fixboot. The Dell came with a Windows XP recovery CD (not a microsoft one with logo, but a Dell CD that says XP recovery on it. Hopefully that CD does contain the recovery console. If not, can I download it as a bootable CD or get it from anywhere else (or could I use my own XP Home CD to boot from?).
Cheers for any advice
