Then the UEFI would be enabled and I would gain what?
I'm guessing a GUI interface to access the bios?
Thanks for the replys. I am starting to understand this now, I think.
Here is a link to the laptop -> Toshiba Qosmio X875-Q7290
No, not all correct.
From what I understand, if the BIOS is set to UEFI mode and then
you install Windows 7 the installer will do all the hard work. It will set up the GPT, create the needed partitions, and install Windows.
I am not sure if you can alter an existing legacy BIOS installation to work on a UEFI BIOS, I don't have that experience. But I'm pretty sure cloning would be a no.
You do not need
to create GPT on any other data drives. That is only necessary if you want partitions that are larger than 2.2TB. The extra drives can be MBR and work fine alongside the GPT disk and vice-versa.
Note that any and all partitions created will still be formated NTFS. That does not change.
UEFI will be enabled only by doing so in BIOS Settings. You do not gain anything immediately by doing so. It is probably not worth the effort if the laptop is all set up. If I can dig up an article explaining the benefits of a UEFI system I will do so (no time now). The GUI interface is not automatic. That has to be set up by the manufacturer. Most laptops use a hybrid BIOS - a UEFI platform but a legacy BIOS interface. I don't know if this can be changed or upgraded.
But if it's a new laptop I would not go changing things just yet. I would only make that change to gain something tangible.
Are we having fun yet?
