I have a Dell desktop running XP home edition which was fine yesterday. Today when I turn it on I get the BSoD which says UNMOUNTABLE_BOOT_VOLUME and has STOP code 0x000000ED followed by other codes which vary but generally begin with 0x8A7A...A similar thing happens when I try to run it in safe mode.
I have read the posting about stop codes but not sure that all the stuff about cables can apply here.
I have tried to follow the instructions for the windows repair tool (haven't found the repair disk but have downloaded something and used that) but it says it cannot find the EULA so can't continue. (I tried following instructions in another post first, which weren't quite the same so am worried I might have done something wrong).
Any ideas please? Please explain clearly as I am not a techie.
Also I haven't done a recent backup so if it isn't going to be fixable is there any way of retrieving data?
