You can install Linux using a bootable USB. below is a link to a forum thread which you'll find useful:

This laptop is a PIII which may not be able to boot from USB. Do you have a working CD/DVD drive?

You didn't mention the distro, so how can we recommend anything ?

sorry for that...its a p3 laptope,its not support usb boot,the only one way is network boot,so please help me with that

Again the question...

The specifications of this Vaio say that it has a CD drive. Is yours not working? Do you have any operating system at all, any backup CD to install one?

If you have a working CD, try a live-cd. You will have to change the device boot order in the system BIOS. If you can boot Windows, you should be able to use UNetbootin.

Try http://www.netboot.me/ or http://boot.kernel.org/ if you have a way to boot a floppy.

Guess you could also fool around with a gpxe or pxe server. See also slitaz.

I sometimes mount a shared cd or other networked installable drive on a lan and boot to some floppy or cd for network install. Many distro's have it. The most easy way to boot to linux is a Knoppix cd/dvd. It has a setup for knoppix terminal server. A few mouse clicks and you can remote boot your old system to a lan.

Might be able to use something like plop.

The issue I see is that you most likely have very little ram.
