This Acer laptop bought in Hong Kong one year ago does not boot. It doesn’t start up even in safe mode. We get the blue screen with error 0x0000007E and 0x0000007B. After a thorough check we find out that it has got unrecoverable file damage. First we save all important data, after that we reinstall windows and put the saved files back into the system.
