Windows 7: Cannot partition unallocated space on 4TB hard drive

11 Jan 2015   #41

Windows 7 Home Premium 64 bit

Okay last attempt before I give up.

I went to command prompt and convert to GPT. It says successful. I don't create prinary partition of anything like that and proceed to install windows. i select the disk to install windows and it lets me but I noticed the disk doesn't say anything next to if whereas when I did the prinary partition before it had GPT as disk type but when it I sekevt that GPT paryition disk it says windows can't install. It's like a never ending nightmare. Let's me do one thing but not the other. Can't have GPT andinstall windows on it apparently.

I have a headache and that seagate wizard thing is looking mighty tempting.

After converting to GPT I used this tutorial Partition or Volume - Create New
It didn't say to create the 800gig. I just followed step by step on this tutorial.

After that I proceeded to install windows but when I selected that GPT volume it says I couldnt install windows becos its gpt.
I have no further ideas other than what is in my last post.

It could be a motherboard/bios setting/capability issue.
Is this PC UEFI capable, and is it set to UEFI ?

You need to find the manual for your PC and/or motherboard.
If it's a pre-built PC include the make and model in your SF system specs.
It it's some type of custom built, include the motherboard make and model in your SF specs.

This tutorial by Brink can help with updating SF specs:

I found an MS forum thread that sounds like the same issue you are having.
It's 18 pages long, and has been going on for over 3 years.
It's all over the map on what works, what doesn't ...

unallocated hard drive space
I have a 5610Z Acer Aspire with Windows 7 (32 bit). I pulled a very boneheaded move getting to upgrade from Vista. I deleted my D:drive (50 G). I back up to a 500 G external hard drive. Is there a way to add the 59G to C:drive where I could use the space. Thanks Brightlight864:o
