My friend was updating his Windows OS when the system lost power and crashed. When he tried to boot, the disk drive pined but couldn’t be accessed. I think the Master Boot Record got toasted that’s why he can’t access the drives.
What do you guys think? Please help me help out a friend. Thanks.
It often happen by a sudden Shut down.
Usually what happens is that when a HDD ages careful sectors that are often accessed get unclean. When that happens to a division where data for windows is, you can see things same puritan screens of dying, casual freeze ups and windows weakness to get underway with errors near the OS.
1.     Normally is can be solved by power on the system and suddenly unplug the CPU from main plug. 75% system recovers by this.
2.     Now if you really want to reinstall windows, it will put down windows on fresh sectors, but those sectors leave also do up vitiated yet. Message it will do it again.
3.     So at the end buy a fresh HDD.
You may also try this one out if this is still possible with the current state of the hard drive. Install Partition Magic on a working computer. When the installation is done, shutdown the computer.
Remove the hard drive from the other computer that crashed and then install it to the computer where you installed Partition Magic. If the hard drive is already secured inside the CPU, start the computer.
If the hard drive can still be detected, hopefully, the BIOS will automatically detect it and install the hard drive.
After Windows has finished booting, open Partition Magic then try if it can still access the crashed hard drive. Try if the application can still delete the whole partition of the hard drive.
After deleting the partition, create a new one. Shutdown the computer then transfer the hard drive back to its original CPU. Then from there try installing a new copy of your Windows operating system.
