Installing newer version of Ubuntu without a bootable floppy or thumbdrive
I have a older machine that has Ubuntu 10.4.
The bios will not allow me to choose the USB drive for bootup.
The CD drive is old, and doesn't work.
but, I would like to install the newer 12.04? Ubuntu on the machine.
When I try to do it through the software, it just returns errors, and doesn't allow me to upgrade or update. This same error seems to happen on all the machines that have older versions of Linux.
My question is:
Can I somehow do a update to the system and update it to the newer Ubuntu? maybe through a command line?
Thanks in advance.
