Input/Ouput disk errors are usually a sign of a broken disk.Here is the output
The one mention in your screenshot is sda, that is probably the disk that you are trying to do your install on so I suspect that is the disk which is broken. When you are live booted, can you do another dmesg and then like this and share the output.I have four and they all show the same thing
dmesg | grep sd
Where are you seeing those error messages for all 4 disks, in the last screenshot(ubuntu-2.jpg) I only count 3 disks? Can you also share the output of lsblk?I have four and they all show the same thing
