If you have a bootable USB drive and your bios supports USB booting, you could try to copy a boot image (boot.iso) on it and try a network installation. But you'll need some hardware to boot from...
Hmm, if you have windows installed, maybe the following link provides a solution:

But I don't know if this will work with newer versions.
