I'm trying to install Ubuntu 18.04.3 on an old HP Desktop. I already reformatted the hard drive (tried both unallocated and EXT3) and yet haven't been able to select the partition during install. Any and all help is appreciated.
EDIT: Adding screenshots for gparted and failed installation error message.
Remove /dev/sda1 partition and create a new ext4 partition.
It is unclear why you selected ext3. Most likely Ubuntu can't be installed on ext3 now because it is obsolete.
I installed a dual boot on a newer Dell recently, and I had to change the SATA from IDE to AHCI (or the other way around) in the BIOS before the partitions would show up on the installation screen. Might be the case here.
Why does the Ubuntu installer not detect the hard drive during installation?
