I have one question for you all.

My notebook is Toshiba satellite
A105-S4284.I am Using windows xp professional. My DVD Drive is not
working. I tried to boot from dvd drive but it is unable to boot from
dvd drive. It cannot read Cd either. I want to reinstall  operating
system.As notebook is infected by some  Trojan virus. Computer is very
very slow and sound is very distracting. It takes 10-15 min to boot and
to use.

This notebook supports 5 boot option 1) HDD 2) FDD 3) cd/dvd 4) lan 5) usb drive

Here is my question.

working?and i dont have recovery partition in my notebook.Is there any
way we can use usb drive to Install new operating system. If yes then
how? please let me know.
