At some point, the installation should ask you the driver on which it should be installed and also how the driver should be interacted with; i.e full wipe and then installation or only specified partitions. You specified elsewhere that you don’t intend to dual-boot. Hence, selecting the correct drive and following the instructions for full wipe + installation (which should be regular/default installation) should have been sufficient.
Partition size wasn’t specified in any step of the setup. If that is the issue, Is there any way to fix it?

That is what I did
