"UNMOUNTABLE_BOOT_VOLUME" - Windows 7 laptop will not boot, goes to Blue screen after "Starting Windows" screen
My computer crashed this afternoon (I was not manually downloading any Windows updates). It cut to a Blue Screen. It read "UNMOUNTABLE_BOOT_VOLUME". I turned the laptop off and restarted it, and after the "Starting Windows" screen, the laptop shows the
BSoD for a split second and abruptly shuts off, restarting (using a Safe Mode option, I see it is the same BSoD as before). All Safe Modes lead to the same thing as starting Windows Normally, and running Startup Repair leads to a blank black screen with an
big white cursor. all input has no effect at that point.
This is serious error and "may" not be repairable without professional tech support from
a real computer shop (not leeks and peeks at a BestBuy or other BigBox Stores) or your
System maker's Support.
Here are the troubleshooting methods to try to fix the issue :
Try Startup Repair - (If at ANY point you gain some but not full access to Windows come
back and try Startup Repair again.)
