Boot from USB using GRUB
Problem
My friend's laptop was in a car accident (he's fine!). However the laptop is very old its an Acer Aspire 1520 the CD-rom drive is broken and there is no floppy drive.

The only thing I have is a GRUB console but he is keen to just install XP (on USB) and use it just for Movies. Is it possible using the GRUB console to get access to the USB and start the windows install? It's a tall order but I think this may be the way, or trying to install via LAN which I don't think will be achievable.
