After running into some issues attempting to install slackware 13.1 on my 2TB seagate, I decided it may be best to try 13.37 due to support for GPT.
I've obtained the slackware64-current-iso.iso from Alien BOB. He's put gdisk on the install dvd.
So on to my main question, after booting from the disk and running gdisk to sort out partitions, I'm greeted with the following message:
Found Valid MBR and GPT. Which do you want to use?
3. Create blank GPT
To be honest, I'm not sure which to use? Suggestions?
