Is this an older machine? I remember old BIOS problems when hard drives started getting larger. Check with the BIOS manufacturer for an update or the hard drive manufacture for software to help get around this problem.
If you are having the problem that I’m thinking of, the basic issue is that the BOIS doesn’t know how to talk to the larger hard drive. Back when hard drives were small the BIOS companies setup the BIOS to only address so many sectors on the disk. As drives got larger the BIOS companies didn’t correct this. For a while to install a hard drive with over 130 something gigs or more of space you had to install special software to get around this problem.
If your computer Operating System cannot recognize the installed hard disk drive, there might be a problem with the hardware part of your computer. You should check the connections of your hard disk and make sure that it is working and properly connected.
