“I recently downloaded and installed Windows 8. After making a repair disk for it, I tried to backup the system onto my external drive. I was unable to complete the action. The PC wasn’t recognizing my external drive, even though it was showing up in “my computer” and in “administrative tools”.
When trying to backup onto the external drive, I kept getting windows telling me that the backup drive was not being recognized. I have two partitions on my external drive. I formated the partition before I tried to backup the Windows 8 PC.
Now my PC won’t boot up. I get the splash screen, then a window telling me that the “boot manager is missing”.
I tried using the restore disk, and that didn’t work. I went into the BIOS and set everything to the default settings. Didn’t help. Then I found in the BIOS that the hard drive and the CD / DVD players were being displayed as “dissabled”.
How can I fix these problems ??”
