Installing Ubuntu on laptop without CD ROM or USB boot

[usman4575]

Hi,
I am new to Ubuntu forum. I tested a month ago with my bro's PC and really liked it a lot. I downloaded 10.10 version from net. But i found out that my CD ROM drive is not able to read any CDs any more and my laptop doesn't have USB boot option. My laptop is a Pentium 4 with 1.5 GB RAM and is running Windows XP Professional SP 3. I have created 15 GB unallocated space for Ubuntu but don't know how to install in this situation.
Pl help me if i can install it through windows or any other way.
thanks

Check out plop boot manager.
You can install this in Windows and next time you boot you will have the option to boot USB.
