I'm trying to install Ubuntu and in BIOS there is no boot from USB drive or anything like that. I would boot it from disk, but my laptops CD/DVD reader is broken and it can't read anything. Please help?
As I suspected, according to this thread your laptop does not support booting from USB. See post # 16:
All I can think of trying to do would be to remove the HDD and install Linux directly on the HDD using another computer.
