I have seen installs of LINUX from USB memory sticks or USB cd/dvd drives but today, I don't see even the guru's loading from the network. Yes we'll do images and restores from a "Ghost" but not like you asked.
I'm trying to restore my laptop using the original restore DVD's, but the DVD drive is broken. I tried booting from an external DVD drive, but it refuses to (even after changing setting in the BIOS). I'm left with the only option of somehow using another PC on my LAN for installing it over the network... but how would I do this?
