This guide will explain how to fix the 0x80300001 error on the setup screen of a Windows installation. The guide is based on Windows 10 but it should apply to Windows 7, 8, 10 and 11.

This error tends to occur when attempting to install Windows to a non-C: drive. In this case, the C: drive had been deleted while trying to extend it. In such a case, you need to format and name a C: drive for Windows installation to continue

How to fix Windows 0x80300001

Go back to the screen with an "Install Now" button. Click "Repair your computer" at the bottom left
Click Troubleshoot
Click Command Prompt
In the command prompt, run the following command

Code:

diskpart
You should now be in DISKPART
Run the command below

Code:

list disk
You should see the disk(s). In this case, it's Disk 0. Next run the command below

Code:

select disk 0
The disk should now be selected
Run the command

Code:

list volume
You should now see a list of volumes. I'm interested in volume 1 (which says RAW) so the command would be:

Code:

select volume 1
The volume should now be selected
Run the command:

Code:

format fs=ntfs
Wait till its done (a "Diskpart successfully formatted the volume" message)
Run the command:

Code:

assign letter=C
You should see a message like "Diskpart successfully assigned the drive letter or mount point"
Close the command prompt and retry the Windows installation
