Failed hard drive was replaced with new Seagate 1TB. Loaded new restore diskset for Windows7 from HP.
After disks loaded ok, system startup stopped: "OS not found". I went to boot and made sure it was selecting the new hard drive as normal. Went through all the internal diagnostics routines with no errors returned. Tryed loading from disk set several more times but can't get Win7 to load. Is there some other internal setting I am missing?
