It's been a long time since I used one, as I recall not very multi-boot friendly
Decided to try the non-pae mini.iso this afternoon after cloning my HD. Wish i had better results to report, the non-pae did not install a kernel from the archive.. So I decide to flush the attempt and see what I could do with the pae mini.iso which did grab a kernel and I am waiting on the lubuntu-desktop to complete to see if it worked. We will see..
I will probably try that non-pae mini again this weekend when I have more time.
