How to install OS without CD/DVD or USB's?

I have a old laptop TOSHIBA 5005-S504. Here are some details about it:
1.The CD/DVD rom is not wokring...it just wont read CD's or DVD's so I can't boot from it.
2.I use to be able to use external CD/DVD but now the USB's are gone.
3.There is no floppy on the computer (just the USB external, which i can't use)

OK, this computer was like this for a while but it was good enough for my kids. Now, somehting happen and we could not start it up. I post me problem all over the internet but NOTHING. I can take the HDD out and put some files on it like the INSTALLATION FILES of WIN XP or 98 or...but didn't work. Please, can anybody help what do load on the HDD so I can boot the computer somehow and install the OS. I don't care what kind...anything. XP, 98, 3.11, LINUX...somthing....thank you
