GUID partition on main drive?

post #1 of 6
Thread Starter 
Hey all,
I bought a 3TB drive for my main drive on my new computer I am putting together. I want to do dual boot with fedora / windows 7.

My main question is, is it possible to have a GUID partition table on the main (only drive at the moment) drive in the computer? Will windows 7 installer have issues with this? I read it only allows partitions up to 2TB.

My plan at present is to create the GUID partition table in linux (off a live CD), then install windows 7 once it is created.

Anyone know if this will cause problems with the windows install? Alternate suggestions?

Thanks

The BIOS can not boot off a GUID partition table(GPT). Some high end boards offer alternatives to this, such as UEFI, but at the moment a BIOS is the norm. Since you have the 3TB drive, you will want it formatted with GPT so you can use the entire drive and then a smaller drive formatted with a MBR partition table to boot from.

Ok then, if I use an old drive to boot from, can I then run windows 7 off a GPT partition that is on the new drive?

You need to boot to Windows 7 though, so it can't be on the GPT drive. However, you can still install all your programs/etc on the GPT drive.

I think to be exact this is only a Windows limitation. I have several 5+ year old boards including a Pentium M laptop booting Linux off of a GPT partition. Maybe it's something grub does..

GRUB makes a fake MBR. Windows should have that option....

That said, if you wanted to get fancy, you can setup the hard drive boot with GRUB then boot to windows from the GRUB launcher. Though, I'm not sure if Windows will even let you install on a GPT drive.
