My motherboard is Asrock H81M

You may need to Install the ASRock 3TB+ Unlocker Utility ver:1.1

I have checked about this, it seems it will be a extra 7xx gb space for me
thats good but I cannot allocate the disk space myself, I would like to seperate a 100gb space for os or other system installed , and the other 2900gb for storage and gamming

Hi there

If your motherboard does NOT have UEFI you won't be able to boot a UEFI system -- however you can STILL use the entire 3TB HDD by converting it to a GPT disk. A GPT disk does NOT have to be on a UEFI system. I don't think though that W7 will allow a GPT disk to be bootable from a NON UEFI system so you'll have to use it as a second HDD and use another one for Boot. Often a good solution is to use a small SSD for the boot system and then you can use the entire 3TB.

If your system is UEFI capable then just enable it and you are good to go -- you DO NOT have to have protected boot for UEFI to be enabled. In fact IMO it's best to DISABLE protected boot and allow boot in "Legacy mode".

Hi there, Thanks. I checked my motherboard asrock h81m which support uefi.

I put in my windows install disk and install it normally, turns out i can only use 1.99tb of it.
I checked this situation and thought I may have to use uefi boot to install it , problem is I dont really know how to do uefi boot. Thanks

To be specific
when i press "F11" at starting, i directed to the boot menu
but there are only two options , which are
AHCI P0: MY HARDDISK
AHCI P5: MY DVD ROM

where i can not find an option with uefi in it
