Thanks Greg you're champ that explains a fair bit to me at least.

So do you think as I am never going to use anything near 2TB on this machine - my old Intel board with UEFI boot ability that it would be better for me to convert my current set up to a GPT drive set up in order to try the UEFI out?

That would make sense to an old codger like myself. Am currently using an M4 as my main boot drive and an oldish 80GB for a dumping ground for the Users and temp files when I finish up this reinstall.

Bios Boot Settings

AMI Bios

Bios boot choices:
UEFI/Legacy ---- Enabled
UEFI ---- Disabled
Legacy ---- Disabled

I am running UEFI/Legacy ----- Enabled

There is a setting for PC Rom Priorty

Choices are Legacy Rom or UEFI compatiable Rom. Mine is set at Legacy Rom. If there are any ill effects I am oblivous to them.

I can enter the legacy rom at boot with a key stroke I haven't tried it yet.

Looks like you are using Legacy choice to install normally to MBR disk, Hammerhead.

I do not see any reason to use a GPT disk unless it's more than 2tb, or install Win7 on any other than an MBR disk otherwise - thus avoiding EFI mode until it becomes more common and navigable for repairs.

If one needs more than four Primary partitions convert one to Logical to add as many extra as you want. Video help on how to set partition as Primary or Logical.

Sort of answers my query too Greg - thanks will stick with the old BIOS until I get my next board then.

Was EFI Boot Disk set first to boot in BIOS?

What other settings did your BIOS have for EFI, if any?

You really got my curiosty going. Yes my boot disk is MBR. I checked it. That was the only disk connected when I loaded Win. So it was set to boot first. Second choice was the rom deck. I then began to connect my other disks. I post some bios choices in another post before I read this.

Where does one click Greg? I clicked all items and the empty area and I don't see where it says what type disk I have although I know it is a MBR.

Hum went to check myself out of curiosity and got this and have no idea what it is about the ref to help is like trying to find a needle in a proverbial.

Have two drives in a Samsung 830 main boot and a Seagate for the Users and temp / data files.

However haven't used the Seagate yet as I have only just reinstalled for the sixth time for reasons that are far too long to go into here on the 830.

Check to be sure you didn't uncheck VDS in msconfig.

Rightclick on Disk # on Drive Map as shown below, choose Properties> Volume tab.
