Thanks.
I've got an old windohs install from which I could scavenge a lot
of space- dump things onto USB sticks. I could resize the sda3  partitition
 if that is fairly safe and create a new one of at least 30gb. 
If I get the Ubuntu  18  or 20.04 ISO
is there an easy way to just install that on this new partition
while running Ubuntu 11 ?
I've got the Bionic Beaver ISO somewhere and presumably I could
put that on the new partition and update GRUB.
