I tried to install Ubuntu to a desk computer but there were no disks/partitions listed in the installer. Switching to a console and running fdisk -l listed the disk and I was able to partition it using fdisk, formatted to ext4 but it still wasn’t listed in the installer.

The solution: I used this disk in a motherboard RAID setup earlier, I just had to enable the RAID controller in the BIOS, enter the controller’s setup and remove RAID information from the disk. After that, I was able to partition the disk and continue Ubuntu install.
