I am trying to factory reset my pc

Greetings Crean,

I am Dave, and I will assist you with creating a Windows installer boot drive. Since you are experiencing issues resetting your PC, using a boot drive can help you to perform a fresh installation of Windows 10.

Please follow the steps below:

1. Visit the official Microsoft website at this link.

2. Download the "Create Windows 10 installation media" tool from the website.

3. Once the download is complete, run the program and follow the on-screen instructions to create the installation media.

4. Boot your PC from the USB drive.

5. Once the boot process is complete, proceed with the installation of Windows 10.

Best regards, Dave

Hi Crean, This is Ramesh.

If the reset operation doesn't work, you can cleanly install Windows 10 using the USB setup disk.

First, please create a Windows 10 USB setup disk. You'll need a USB stick of 8GB or higher capacity to create a USB setup disk. The contents of the USB stick will be erased during the disk creation process.

Download Windows 10 Media Creation Tool (MCT) from this link:
https://go.microsoft.com/fwlink/?LinkId=2265055

Run MCT and create a bootable USB disk.

After creating the USB setup disk, boot the subject computer using it. To do so, you may need to change the boot order in the BIOS/UEFI settings. Consult your system or motherboard manual to learn how to access the UEFI settings for your model.

On the Windows Setup screen, click "Install now"

I did your steps, everything worked fine until I’m on the collecting information step. When asked where do you want to install windows. All of them show errors, under drive 1 I allocated space, it says it is a mbr partition table on efi systems windows can only be downloaded on gpt disks. I clicked on “custom install windows only” is that correct?

When doing so, I went through instruction, when asked between upgrade windows, and custom, I chose custom. When prompted in where I want to install windows, none of the space are available. The drives each day either there is not enough space. And on the ones that do have enough space, it says it’s not a gpt.

Hi Crean,

If you have already backed up the data to an external drive, simply delete the OS partition and do the clean installation.

Or, delete all the partitions on the Operating System disk. Please be careful not to delete the partitions on the secondary disk, if any.

After you delete the partitions, it shows up as "unallocated space", as in this screenshot.
