I also ran into this issue recently (Ubuntu Server 20.04 setup stuck at "Block probing did not discover any disks"). Attempting to install ubuntu-20.04.3 onto a Dell Optiplex 5080.

The following does not work for me unfortunately on ubuntu-20.04.3-live-server-amd64

Early-commands:

losetup -d /dev/loop0
umount /isodevice

Any ideas as to what I am doing wrong? I have done both checking the hash in the iso file and execute the unmount of the /isodevice...

I was also trying to install Server 20.04.03 on a Dell 5080 machine. The commands above didn't work for me either. I was looking through the BIOS and under System Configuration - SATA Operation the default was set to RAID On. I change that to AHCI and rebooted the machine. I don't get the block probing error anymore and can complete the install. I don't know why this works, but it does. I hope this helps.
