Okay so I have an OLD OLD gateway desktop that I was hoping to use as a server. It currently has Windows XP installed. The catch is, I want to install CentOS or another Linux server distro, but my computer has no internal CD or DVD drive. I do have a external DVD USB drive, but this computer is unable to boot from USB and for whatever reason the bios doesnt recognize that as a recognizable drive to boot off of. I have an accessible windows and mac machine, I just need to know how I would be able to do a fresh install on this computer. I thought of installing the OS to a thumbdrive, and then restoring that onto one of the two hard drives in the original computer. Please help I really need this computer to be restored.
