I am in need of a respected computer repair company/person to restore/repair my Dell either in home or in shop. I have the black screen of death and an error message that a boot sector of the hard drive is damaged/corrupt. I'm mostly concerned with saving the files on my hard drive, as not all were backed up. I found the proper commands to write to try to repair the boot sector, but am unsure of how to save my data first. Thanks for any referrals.
