I recently reimaged my Lenovo t400 with Ubuntu. However, after wiping two other systems (Compaq Presario 2100 and Dell Latitude D600) both Ubuntu 11.10 and Ubuntu 12.04 fail to load on boot. I am concerned that there is some type of issue using Ubuntu on these older systems as every part of the process has been repeated/attempted several times in the same manner as practiced in the successful load of the newer Lenovo t400.
I now have two laptops without an operating system as the discs/thumb drives that were formatted to load on these devices do not seem to work. I would appreciate any assistance that you may be able to provide.
