Right, that's what I thought you meant.

It's a real pain that manufacturers all want to save a couple of bucks
by not giving us install disks any more. >:(

No no, it's fine, not a problem, I just wanted to make sure we were
all on the same page.

Yes, that's true.

My concern is that in your case, you might need to make the disk MBR
for Linux to dual-boot correctly, and if you do that, I think you will
erase all the partitions on it.

Then if you restore W8 from your DVDRs, then it will just restore it
back to GPT again and it will all have been for nothing!

OK. Again, I thought this but I just wanted to check.

And as I understand it, now, if you install Ubuntu, it just leaves you
with a black screen at boot-up?

On my Toshiba (*not* UEFI), if I use `nomodeset` then the screen
resolution comes up wrong and I can't change it back. Is that
happening on yours as well?
