EFI BIOS: Installing Windows 7 on a GPT 4TB Harddisk drive.

Hi,

This question seem to be asked so many times, but I couldn't find any real answer so far. That would be: a satisfying answer.

Situation:
A somewhat older system (2008) carrying a MSI Neo P43-F motherboard (http://www.msi.com/product/mb/P43_Neo.html). Since it's BIOS never got touched, I just finished upgrading to its latest 1C (or as the system now refers to it as 1.12).

The AMI BIOS installed doesn't seem to support UEFI. Nor does the term Legacy pop up (except for USB Legacy). Bottomline: I'm stuck with an EFI-based BIOS.

As for harddrives, I always ran 2TB or 1.5TB harddrives with no problems. Since my maindrive has been giving problems (random clicking sounds), I decided to disconnect it as soon as possible and buy me a new harddrive (best chance to be able to recover anything at all). Not knowing about the EFI/UEFI rule. So I bought a new 4TB drive.

Being confused why only 2TB were accepted, I started searching the internet. That's basically where I'm at now.

What have I tried:
- Update BIOS to latest version
- Use different Boot CD's to partition/switch between MBR and GPT, etc.
- Try installing Windows 7 experimenting with MBR/GPT/Boot CD's, etc.
- Google the problem, trying to figure it out on my own

My question:
Is there, to this date, any real solution to be able to let the 4TB harddisk be recognized by an EFI BIOS/mainboard? Without spending any more money, that is.

Solutions?
Like I said; I did do some research, but before trying any of them, I was gonna take my chance and ask you guys first.

1) http://rodsbooks.com/bios2uefi
- This seems to be a legit solution. A lot of work though...

2) http://rufus.akeo.ie
- I wasn't sure if this tool could be of any help. I saw some options with MBR/GPT and creating a bootable flash (USB) drive. I used it before to be able to create a bootable USB for upgrading the BIOS.

Any help would be highly appreciated!

- I could return it and buy 2x 2TB drives, but if there is anyway to bypass this problem, I'm in.
- Same goes for installating a second (smaller drive) and use the 4TB drive as a 'slave'. I prefer not to.

Thanks!

You can try it, but honestly, I've seen nothing but problems with trying to use work arounds for large drives on non-UEFI systems.

Even if it did work, it would likely be highly un-optimized for the storage controller and aside from that, if you have to upgrade, might as well upgrade to a faster solution.
No, there is not. Read this. Simple and to the point. Since your motherboard is not UEFI there is no way for it to support a GPT boot partition which it would need to do to support larger than 2TB.

But that's if you're trying to use it as the boot drive which kinda doesn't make sense anyhow. If you're looking to use it as the boot drive, get a 120GB or 240GB SSD and a 2TB drive for storage. Or two 2TB drives, but it will be much slower. Of course, your board needs to support SATA, which I'm assuming it does because I'm not aware of any 4TB IDE consumer drives anyhow.

Thank you for your answer.

The first 'solution' I gave actually does seem to work. But before I was gonna undertake this big operation, I wanted to see for an alternative.

I was gonna split up the 4TB drive into smaller bits anyway. No use in a 4TB C-drive. More of a space/cooling-solution inside the case.

SATA indeed ;)
