I had posted about a problem with my hard drive. black screen error disk error occurred press crtl alt del to restart then goes right back to the error black screen. I tried going to alt f10 for recovery and one option to and it is shaded out. The bios does show the hard drive. I put the hard drive in a working computer and it shows the drive with no data on it . Someone said it might be the master boot. Does anyone know of a SITE where I can download a recovery for the master boot. After performing the alt f10 everytime I boot the system it goes right into checking files and goes to the recovery. This is a gateway laptop model m6847 (64). I put Ubuntu 12.04 and it had a option to view or download so I view did not download it .Not sure as I am beginner only now a little and help appreciated. Thank you Hi, My first post here will HOPEFULLY help someone.  From your sig you are using XP.  Boot from your XP install CD.  Go to Recovery when the menu comes up.  In Recovery there are numerous commands.  One is fixmbr and the other is fixboot.  It will warn you about screwing up other PARTITIONS if you use fixmbr, so MAKE sure you remove and unbacked up important data before you execute fixmbr.

And, in you CMOS, make sure you drive boot order is correct.

M$ has a nice list of the commands if you care to search for it and then PRINT it out.
