I am setting up a computer to be a server for backup usage. I bought a 500 GB SATA hard drive and replaced a 50 GB PATA harddrive with it. I disconnected the cables which were connected into the old HD and plugged the new SATA harddrive into a plug on the motherboard names "PRISATA" or something like that, I assume meaning "PRIMARY SATA". I also connected the power cable to a matching connector.
So I inserted my debian CD and booted it. Debian detected the 500 GB harddrive and installed to it successfully. I also told it to install the GRUB bootloader. At this point, I restarted the computer. However, the harddrive was not detected and it gave me an error. I restarted and entered BIOS and found that the HD was not detected, only the CD drive.
What am I doing wrong here?
