I am trying to install Xubuntu on an old PC with:

• A USB port that can't boot, but otherwise works fine.


• A CDROM drive that can boot, but is extremely slow and fails often.

I created a USB stick with usb-creator, burned the Xubuntu 12.10 ISO to a CDRW, inserted them, then switched on, selected "Try Xubuntu".

It took 2 hours, but now I am trying Xubuntu and writing this question from it.

QUESTION: How can I now install from the USB stick, rather than using the extremely slow/faulty CDROM drive?

Actually, installing from CDROM is not even an option, so I must find a way to use the USB stick, despite my motherboard not being able to boot from USB. Here is why:

Because of a bug with Athlon CPUs, I must remove a particular package, and I get a read error from the CDROM drive:

sudo apt-get remove ubiquity-slideshow-xubuntu 

Reading package lists... Done

Building dependency tree       

Reading state information... Done

The following packages will be REMOVED:

  ubiquity-slideshow-xubuntu

0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.

After this operation, 1263 kB disk space will be freed.

Do you want to continue [Y/n]?
