HO 110-243w no boot device found
I have a HP 110-243w desktop I was using it earlier the other day, I shut it down, and came back a few hours later, to find it said it could not find a boot device. I ran the checks on the HDD and everyhthing says its fine. I pulled the hard drive out of the tower and connected it to my laptop via SATA to USB converter all files are still reading on the HDD Everything seems to be in place. When I put it back in the desktop still it can not find a boot device. I can boot from a DVD ISO and do a clean install. I do not want to loose everything that came with the computer when it was bought. Any ideas on what may be going on here.
