Ubuntu Server 18.04 and 20.04 fail on 2010 PC

At the moment I am trying to install Ubuntu Server on a PC made in 2010 (this is not the first time I have made a server on old hardware), however when I attempt to install Ubuntu Server 18.04 the installer will report “Unable to install Ubuntu Server 18.04, please try again…” or something of the like. Trying the ‘mini.iso’ version of the Ubuntu Server 18.04 the installer freezes after pressing install. Trying Ubuntu Server 20.04 the installer makes it further but eventually does the same as the first instance, however the only difference between 18.04 and 20.04 is that before 20.04’s installer launches it reports three times ‘blk_update_request: I/O error, dev fd0, sector 0’, it then continues as normal. Does this have anything to do with the failed attemps? Some extra info, I have two identical 500GB harddrives and a similar 250GB harddrive, I’m attempting to run the two 500GB hdds in a RAID0 config and then have the 250GB drive for Ubuntu Server itself to install on. Thanks…
