Hello, I am trying to fix a computer that was given to me by a friend. She told me that the motherboard was replaced, i don't think so. i get a blue screen with the error of "unmountable_boot_volume" and at the end it has Technical information: ***STOP: 0X000000ED (0x812e2cd8, 0xc0000006, 0x00000000). i cant even get into the safe mode, what can i do? Do you think i need to replace the hard drive OR can it be fixed?
