Linux Application Server

Is it rattling impracticable to establish an OS on a computer incase that does not hit a guardian or modify a CD or DVD or disc drive. It has a usb opening however. I do hit a keyboard.

I undergo we crapper do a meshwork establish - but I ease requirement to create something bootable right? To do that I requirement to admittance the BIOS (on a monitor) and modify options to rush from the usb for example.

I hit a laptop which has Win XP installed - would that support in whatever artefact - maybe ingest the laptop monitor.

At this saucer I am disagreeable to encounter discover if it is modify doable to establish whatever OS (linux) without a guardian / CD / DVD / floppy?
