Booting linux from GPT currently has its share of issues, http://www.rodsbooks.com/gdisk/booting.html (and follow the appropriate links)
Mostly you will only be stuck with GPT if you are installing to a MAC, that's not the case here.
 Can you tell us about your hardware?
 Did you choose to setup a GUID partition table, or did the system come with windows installed on GPT?


I built this PC. It has an LGA 1156 P55 Motherboard.
I didn't know about GPT. I assume it must have an EFI BIOS.
For storage I used a 128GB SSD. I thought I would need most of that space for Windows 7-64, but it turns out I'm only using 45GB or so at the moment. Perhaps I can resize that partition, to install Linux /, while
putting user storage on the hard disk (similar to how I set up Windows 7)?
I also have a 2TB SATA hard disk. I used SATA only on this PC, nothing has IDE.
I don't actually remember how I set up that disk. I used a program from within Windows 7, to set aside a partition for a future Linux installation. I don't remember if there was a choice for using GPT, but I think I used the recommended options, whatever they were.

Video card is an NVidia GT240.

Only if your definition of better varies from that found in all the dictionaries I'm aware of.


Just going on 2 factoids:
GPT also provides redundancy, writing the GPT header and partition table both at the beginning and at the end of the disk.
GPT allows 128 partitions.
in addition to the non-relevant for my setup that GPT allows > 2TB.

Fedora is likely to be the easiest for now, but you could help to get PCLinuxOS working well with GPT by giving details and trying suggestions that may be offered, (with PCLOS as a test distro).


I didn't actually come across PCLOS as a download link anywhere. Is that shorthand for "PCLinuxOS"?

I got it to work. I am posting this using PCLinuxOS.

I shrank the main partition on the SSD, leaving 12GB free. Then using the PCLinixOS live USB, I set a mount point of / for that 12GB, formatted as ext4.
I set the partition on the GPT hard disk to have a mount point of /usr. The other small partition there is still setup as Linux swap.
Then when I set Grub to install on the SSD, it worked.

Thanks for all your help.

OK, But you are booting from "MBR" not "GPT"!

I'm glad you got it working!
