Can't Install Windows "Selected disk has an MBR partition table"

[yngse]

I've been researching other forum threads and trying now for hours to get this to work. All I wanted to do was reformat my samsung evo 750 SSD and reinstall windows. First I downloaded the windows 10 media creation tool to a USB. I successfully booted to the USB and got all the way up to where it says "Where do you want to install Windows" after selecting install windows only. Selecting my SSD it says I can't install windows on this disk stating, "Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed on to GPT disks".

I've looked online that I have to change bootable devices in my BIOS from UEFI to Legacy. I tried a couple of the options but they didn't seem to do anything. I'm still stuck and can't install windows to my SSD. I "reformatted" the disk by connecting it to my laptop with a usb to sata and quick formating it since samsung magician won't let me make a boot drive to secure erase. Still nothing... I don't honestly know what I should do from here. Any advice would be appreciated!!

Motherboard: GIGABYTE Z370 HD3

SSD: Samsung 750 evo 500GB


TLDR: My partition table on my ssd is MBR and windows won't install to it. How do I fix this?

Since you can't secure erase the SSD (which is the optimal way), you simply have to delete all the partitions on your SSD and create a new one during the windows installation process. Formatting doesn't do that. It just formats the current partition. Check this => https://www.groovypost.com/howto/clean-install-Windows-10/. It contains detailed instructions on how to do it.

Connect that drive to a laptop or another system. Open disk manager and delete any partitions on that drive. Right click on the drive and select “Convert to GPT Disk”.
