Fix Windows 10 0x80300024 Error

On attempting to clean install Win10 on a laptop I got lazy and I failed to follow my own advice.
I usually disconnect all drives except the one I’m going to install the OS on and run diskpart to wipe. I didn’t this time because I was too lazy and didn’t feel like spending the time to disconnect my second SSD. I got the error 0x80300024 during install. I Googled it and apparently this error has been happening for years. The fix?
Disconnect all other drives and attempt the install again. That’s it!
