Hello!

Welp, I have this 250GB SDD where Win10 is installed. I used to have Ubuntu in DualBoot so I made a 60GB partition, leaving 170GB for Windows and programs. After a cleanse, I only installed Win10 leaving an unassigned 60 gb partition. I think the problem is that Windows has created a 3 partitions plus the 170GB's so that makes 4 and impossible to create and use the rest of the SSD.
I'm ask this: Is there anyway to use those 60GB without reinstalling everything?

Thanks beforehand!

Use diskpart to delete recovery partition.
  • diskpart
    list disk
    select disk x (select 232GB SSD, should be number 1)
    list partition
    select partition y (select 450MB partition, should be number 3)
    delete partition override
    exit
Make sure you select the right disk and right partition before delete command!

Post screenshot from Disk Management.

Thing is - MBR partitioning scheme allows only 4 primary partitions on the drive (or 3 primary + 1 extended).
You could probably delete some recovery partition and that would allow you creating another partition in that 60GB free space or
you could extend your OS partition and assign unallocated space to it.

Yeah, I was considering doing that, but will I need the recovery partition later?
Disk Management doesn't allow me to extend the OS volume..

Since your OS is Win 10 and if you have the latest Win 10 updates (specifically the "Windows Creator Update") you can easily convert your present MBR-partitioned boot drive to the GPT-partitioning scheme which will allow you to create as many partitions as you wish.

This "MBR2GPT" tool is simple to use and very effective based upon our experience with it.

Do a Google search on "using the Windows 10 MBR2GPT tool" for step-by-step instructions.

One minor complication with this approach - system must be UEFI compatible.
And it most likely will cause problems booting other OS-es.

BTW - GPT also has a limitation on max number of partitions. No more than 128 are possible.

Well, I could try delete the recovery partition since I have the bootable USB for Windows...

1. The OP is running with a MSI 990FXA-GD80 Socket AM3+ MB so there will be no problem re the UEFI interface.

2. Yes, there is a maximum limitation of 128 primary partitions using the GPT-partitioning scheme. But tell me, when was the last time you (or I, or anyone!) created multiple partitions of any size near that one! For all practical purposes a GPT-partitioned drive can contain as many primary partitions as a user desires.

3. And the whole point of the Win 10 MBR2GPT conversion tool is that it's designed for a Win 10 system.

Excuse me, do you have any idea how to do it? Disk Management doesn't allow me to.
I don't know, it appears on This PC and is occupied with 155mb. But it's empy tho, not even hidden archives are shown.
