I'm trying to restore a older HP pc for my brother for general use(internet). I haven't tried booting it since about November 06. I booted up the computer and then got the message. I decided to go ahead and reformat the HD, it was full anyway. I used WD Data Lifeguard Tools to reinstall the HD which was fairly simple. I was then prompted to choose which Windows version I would install. I chose ME with that being the most up to date actual copy I own. After inserting disk and resetting the computer, it came up to a black screen, then the error "Operating System not found". Now I have already went into BIOS and set it up for CD-Rom, Harddrive, Removeable devices, and network, so I'm sure nothing is wrong there. The HD is recognized in BIOS as well. I tried to insert the Restore CD that came with the HP, which when booted it installed Windows 95. The only problem with that is that it only let me run it in Safe Mode. If I tried to run it regularly the computer would just freeze. So, I reformatted the HD again in hopes of installing ME again. Still, no help. If I insert a Restore CD, it will boot, but says it is uncompatible with the computer. When I insert any windows disk, it won't even read them. Any help is appreciated because at this point I'm pretty confused. On a side note I was thinking of installing 95 and then doing a upgrade to ME or XP, but since it will only let me run it in safe mode, I have no idea on how to even do so. In safe mode the CD drive is not recognizable.
