Have a look IF this helps:
When booting up to Win XP you may get a error that reads "Unmountable Boot Volume".
1.The file system is damaged and cannot be mounted.
2.You use a standard 40-wire connector cable to connect the UDMA drive to the controller instead of the required 80-wire, 40-pin cable.
3.The basic input/output system (BIOS) settings are configured to force the faster UDMA modes.
I seem to have picked up a virus on my PC. My Virus program detected and neutralized it but it still infected the PC. The first symptoms showed up as the desktop changing to a dark red image wanting me to purchase protection for my PC and "Virus Alert" is now showing on all files and on the bottom toolbar next to the clock. Endless pop ups telling me I have a virus will not go away and icons on the desktop have been changed or totally removed.
I noticed similar cases in this forum but I am not able to try any of the remedies because as time moved on, my PC would not turn on and now shuts down just before loading windows. I tried to boot using the safe mode and this gets me a blue screen telling me that windows shut down to prevent damage listing "Unmountable_boot_volume" as a problem. I did notice also that immediately after getting infected, the control panel icon disappeared from my desktop as well as all other access to the control panel. All attempts to boot up no matter what I try are failing. Can anybody suggest something I can try to actually boot the computer to access logs and to install some of the solutions contained in this forum? My operating system is Windows XP.
