re:HPM bios reset xtra info SW

Morn all. Here are all the msgs comp has displayed when running with Hirens recovery CD.Primary IDE master wrongly assigned. Cannot detect HDD, Boot not set in Partition Table, VIRUS DETECTED.I have run every scan, regenerator, virus, and all results are No errors. All RAM CHKS clear,some of these tests have taken over 3 hrs.
Why does CD Hirens detect HDD and not my system. The above is true when CD is first boot. Password/ is not THE PROBLEM as I can access the bios this way. WHEN HDD is first boot display reads ;corrupt or missing. laptop is Toshiba Satellite L40, PSL-48E, Windows Vista,Sata-PM-toshiba MK12376sx

Hope some answers out there. Ta Henri.
