I assembled my computer two and a half years ago, purely by chance I stumbled upon a comment in which a user was talking about the installation of the operating system in UEFI mode, which I never heard of before.

I checked, following these instructions http://blogs.technet.com/b/home_is_where_i_lay_my_head/archive/2012/10/02/how-to-check-in-windows-if-you-are-using-uefi.aspx, if my OS was installed in UEFI mode, but obviously that was not the case. My motherboard is an Asrock Z68 Extreme 4 Gen3.

So my question is: does it make sense for me to make a clean install in UEFI mode, would I have any advantages?

Thank you.

UEFIs biggest bennifit is in hard drives so that it can support bigger then 2TB drives, more then 4 partitions and more support for boot options.

Im guesiing none of this applies to you so NO, there is no justifiable reason to reformt your drive for the purpose of being in UEFI mode.

What do you mean by support?
I have two 3TB drives that I use frequently (I formatted them in GPT)

Hi!

I want to know how I can boot Windows 7 64bit in UEFI mode.

What's the procedure?

Thanks.

You should make your own thread instead of hijacking this 2 year old thread.
You cant just press a button and switch MBR windows 7 in legacy bios to GPT and UEFI.
You will have to completely wipe and reinstall windows AND your motherboard has to support UEFI or your efforts are dead in the water to begin with.

If you are just wanting to be able to boot windows 7 from a large disk then you should just make smaller partitions.
By having a separate drive for windows (or at bare minimum separate partition) it allows you to restore/fix/reinstall windows without loosing all your files, and you can even backup files to the other disk/partition.

hey! thanks for the reply. It was informative. I just have 1 last question.
Since I'm quite sure my mobo supports UEFI, I might be able to boot in UEFI after re-installation.

But, do I have to format my entire hard drive or do I have to just format the C drive and break it into 3 mandatory drives for the new UEFI?

Thanks in advance :)

Any partition on your hard drive that is MBR has to be formated and converted to GPT.

Not sure where you getting the idea that you need 3 partitions for UEFI to work, nothing like that exists. Windows needs a system reserve partition to install new OS, but that has nothing to do with UEFI.

FYI, you seem to be interchanging the word drive for both a physical drive and a partition.
To keep things understandable if we say a drive we (we being IT Pros) mean 1 physical hard drive, if we mean 3 "drive letters" on one physical drive we refer to them as partitions. I am assuming in your post that you mean you have 1 drive with multiple partitions but it is unclear.

What I meant was, I have 4 partitions (drives) for my hard disk. C,D,E,F.

I can easily let my C partition (drive) to be formatted and let's say win 7 be re-installed in it in UEFI mode.

My question was, Do I need to erase all data from my D,E,F partitions (drives) while converting my entire 500GB hard drive from MBR to GPT?
Thanks.
