I have an old pentium 3 733mhz desktop and I want to install an operating system on it(the hd has been formatted) how would I do this? P.S I have a windows XP install disk
Generally, stick the disc in the CD drive and start the computer ;-) However, the computer has to be able to boot from a CD... but if it has a Pentium 3 it shouldn't be too old.
Yes. At the very beginning when you press the on button on you tower. You should get that option. Usually it's the F2 or DEL key.
