[SOLVED] How to make my unallocated disk space on my hard drive usable

[otto33]

Recently, in an attempt to remove windows 10 from my hard drive as I no longer use it as a boot drive, I deleted the entire drive on disk management. This rendered it basically useless and I now only have 500Mb of usable space while there is 930 Gb of unallocated space. Is there any way to fix this or do I need a new hard drive?

Screencap of your current Disk Management window, please.

That 500MB partition, the D, is FAT32. That needs to change.

OK. First, you test.
Power OFF
Physically disconnect Disk 0 (the 1TB)
Power UP
Does it boot correctly?

In Disk management, Right click on the 'unallocated space' and then select New Simple Volume.
- Accept the size by clicking next.

- Make sure the Dot is next to 'Assign the following Drive letter & make sure you have the letter you desire selected to the right, click next.

- Put the dot next to " Format this..." with NTFS set as the file system, default set as the allocation size, and the label is what ever you wish to call this drive. Place a check in the 'Quick format' box & uncheck the allow compression option; now click Next.

In a couple seconds, your new drive letter should be available.

It boots but much slower than it should on an NVMe ssd

Put it all back together, and follow the above instructions for making that 930.09GB space usable.
Then, remove the D drive letter from that little partition.
