So, I plugged my old IDE hard drive onto my mobo and when starting up to configure the BIOS, it didn't recognize the disk.. I tried to install Windows XP just in case I had luck that it will recognize the drive, but the Windows XP Installer says that it didn't find any harddrives to install to.. then I tried with installing Linux (Debian) and luckily, it recognized the harddrive and was ready to install..
Just what can be wrong
