Newly bought Seagate barracuda hard drive only giving 2tb as available

2tb available
1.6tb(unallocated and unable to create new simple volume)
579mb system reserved(system,active,primary partition)

It is in MBR

I have a 2nd 120gb SSD to which I installed my windows 10 os
It shows healthy (Boot,page file,crash dump,primary partition)

I understand that if I convert my HDD from MBR to GPT then I get the full 4tb...but I'm not able to delete the 579mb system reserved and hence not able to convert to GPT

I have no files on the disk and hence no issue of data loss

How to enable full 4tb??

Open up disk part in run command.

type,
'list disk'

you'll then see a list of disks. look for the name of the disk and type it in.
Ex: 'sel disk 1' (change the number to what the disk number is)

It will say disk 1 selected (or whatever number the disk is). Then type
'list partition' or 'list partitions' I forget which one it is.

it will then show you each partition of that disk. to select simply do again,
'sel partition #' (change # with the partition that is the 500MB)

it will say, partition # selected. Then type
'set id=ebd0a0a2-b9e5-4433-87c0-68b6b72699c7'

it will hopefully say, "partition set to data successfully". Then select the partition again and type:
'delete partition override'

And that should delete the allocated partition.

You need GPT partition table....; if you right click on the drive's icon within 'storage', you should find a 'convert to GPT' option.... If it is the Active Windows installation, there might be no choice but to start over, deleting everything, and selecting GPT within initial installation steps..
