If you are using a non-MBR disk (most disks are now partitioned for as EFS, UEFS or GPT to remove the 4-partition limit and allow for more extensive boot options), then it won't hurt, it just won't do anything. There are some boot repair disks that will actually recognize the format and update the information from the backup table on the newer partition schemes, so, either way, give it a try; you've got nothing to lose.

If you can see the information on the disk, it's likely not a hardware issue. And, while you are in there, you should probably copy off any information on there that you might not be able to recover from a backup.

I think I may have closed it before the shutdown was complete. Anyway when the power came back on I turned on the computer and it would not boot. I get the Alienware BIOS screen then I get a screen with a blinking cursor. I have been trying to install Ubuntu Mate 18.04, but no matter what I do, the install will hang. I have made two bootable USB drives and tried a DVD image. The DVD image did not get as far as the USB drives.

I have tried putting acpi=off and nomodeset on the lines that start with linux in the grub.conf file. My computer is an Alienware 15 R3.
