[GLLUG] GRUB dual boot on removable drive

[michael norman]

I have one of these

Attached to my Shuttle box because I can't use an internal drive for 
reasons I won't go into.

Looks and is flimsy but that's the way such devices are built nowadays, 
but for the increasingly rare occasions I need and optical drive it 
works fine.

Only caveat is whether your laptop has enough usb ports for the two usb 
cables it comes with, ie one for data and one for charging, the supplied 
cables are very short, but standard nonetheless so you can use others if 
needs be.

I don't have Windows but I am sure this or any other of its type will 
work, I just picked an ASUS model because they work for me.
