Ok here is thing( and I now I'm going to end up being dumb one for not knowing it) but I got new PC and thing is that PC doesn't has OS installed....so it is pretty much me being in BIOS.
This of course can be solved easy by just inserting CD/DVD and installing OS....however thing is this PC doesn't has it's PC DVD Drive....so yup, this can't be done that way.
So only way I can install damn OS is trough USB or ADATA on which who I have saved my windows installation(USB has old one like vista while ADATA has 7 and 8). However there are extra things on both my ADATA and USB besides just those installations. So I've been wondering is there a way to boot from ADATA or USB to install OS(despite extra stuff on them) or do I have to delete everything from ADATA or USB that isn't installation of windows so I can boot from them and get installation.
Sorry for being dumb, but I've never done installation with any external device. Usually it was always just insert CD/DVD for me in past.
