I just replaced a bad hard drive in a HP Pavilion 8755c which ran Win/ME on it. I couldn't get my ME recovery discs to work and now I can't get the PC to recognize the HD I just installed. The PC would come up with a message saying "operating system not found" after the install. Since the HD I installed was blank I thought nothing of it. However once I looked in the BIOS it had my OS listed as 98/2000 instead of the ME which it clearly is. It had an option to change the OS to 95, 98 or 2K but no ME option so I selected other. Now that the recovery discs are working I get a message saying "Error : hard disk not found. It could be loose cables or not intialized" and it gives an option to "run an FDisk program to intialize disk. " I don't know what to do! I know the HD is installed correctly as it is listed on the BIOS as the Secondary master and my CD-r is the Primary master. Do you see any problems or solutions?
