Thanks TobiSGD for your response.
I tried Slackware. It doesn't seem to use gpt by default. I tried using gdisk, but ended up with an unbootable system. I imagine if i had been a little more savvy i could have made it work, since gpt is certainly in use.
What i ended up doing was installing Chakra (an ArchLinux derivative).
I think gpt is the default for Chakra, and in any event it is certainly part of the standard installation.
There was a very helpful web page which has step-by-step instructions on how to do this, and i followed it, and it worked.
Thanks again for your quick response.
