Cannot partition unallocated space on 4TB hard drive

So do I do everything again in command prompt and when it says successful just do the added instructions to create primary partition as 4tb?

I will try. Give me some time. I am a bit slow.

That's right.

"create partition primary" would give you a C covering the entire drive, which you could later shrink.

"create partition primary size=200000" would give you a C of 200 GB and leave the rest unallocated, which you could later make into partitions as desired after installing Windows.

Don't attempt to make more than 4 standard primary partitions---DO NOT ever say yes to a choice mentioning "dynamic disks". You may have to use logical disks, which is fine.

I'd make a single C of the desired size in Diskpart, if you know how large you want it to be. Worry about the other partitions after you get Windows installed.

Ignatz, Creating the partitions ahead of time is always a good idea. And why does he not check in the properties of the disk whether he really has a GPT disk now.

He says in post 14 and 16 that he did check and found that it was MBR. So he then tried Seagate Disk Wizard to simulate 2 different disks when in fact there is only a single drive in the PC.

I will create a c partition of 800gigs. Well see if it works this time.
Going to do this now.


Btw I am a she ^__^

Aye aye, madame.

Good luck.

After you run those extra commands, just exit diskpart as before. Don't reboot. Continue on with the Windows installation. When it completes, check again to see if you have an MBR disk or a GPT disk.

We'll get it sorted one way or the other. WHS is very skilled in this.

Primary active is better. Then you do not get a system partition on installation.

Are the commands in post 17 accurate?

Is there any need to assign the drive letter in Diskpart? Or can it just be ignored and just direct the installation to the pre-made partition?

Okay I am in command prompt and it says successfully converted disk to GPT format.

What is my next step?
