I've just installed a fifth copy of Mint from the same DVD, downloaded originally from the web site via Ubuntu Hardy (10.04). First three were over Ubuntu (10.04 and 12.04), next was on "clean" m/c and final one over an old XP.
Worst case was hanging after installation whilst trying to reboot (black screen). After a long while I hit the Reset button on the front of the reluctant machines and away they went.
Of course, no OS ever has what I want out of the box so in each case I spent bits of the next week installing odds and ends. :(
