Install Windows on SSD and There Is a GPT Issue, How To Fix
I was trying to install Windows 10 Redstone 2 x64 on my new PC with 128Gb intel 600p SSD. And this error came to me: The Selected Disk is of the GPT Partition Style. I set UEFI bios to use UEFI and Legacy, and nothing changed. Some forums said to convert GPT to MBR for old machines, but I don't want to do it. I can't figure out how to install Windows on my SSD without converting it to MBR!

According to the information you provided, you haven't completely wiped the disk to reinstall the system. Instead, you overwrite the C drive, which causes the factory structure of the original disk to be limited. To solve this problem, you need to wipe the disk to reconvert the disk to GPT, and then the previous disk structure limitations will be broken so the system can be reinstalled.
In this article, I will offer two tested ways to help you successfully convert to GPT. The first fix is to use Windows built-in tool and follow the steps to convert to GPT using the Diskpart utility:
Step 1. Click the search window and type cmd to open Command Prompt. Right-click and choose "Run as administrator."
Step 2. Type the commands below and hit "Enter" after each.
- diskpart
- list disk
- select disk 5(replace 5 with the target disk number)
- clean
- convert mbr
Step 3. Type exit to execute the changes and quit.
If you are not proficient in using Command Prompt and don't want to lose data, you can use EaseUS Partition Master. This full-featured partition software can convert the disk without wiping data.
Try to convert the disk to GPT via EaseUS Partition Master as follows:
Step 1. Install EaseUS Partition Master on your PC and launch it.
Step 2. Find the "Convert MBR to GPT" feature under the "Disk Converter" tool, and click "Next."
Step 3. Choose the GPT disk you want to operate and hit the "Convert" tap to start.
