Q: “You can’t install Windows on a USB flash drive using Setup.”
When trying to install Windows 10 from Windows Update the install fails and I get a screen that tells me:
“You can’t install Windows on a USB flash drive using Setup.”
I’m not trying to install it on a USB and i’m just trying to install it onto my computer which runs Windows 8.1 currently.
Had the same problem and found this from google.
The second method is what fixed it for me.
- From the Desktop screen press Win + R
- Type in Regedit
- Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
- Change the value PortableOperatingSystem to “0” from 1.
Once you change the registry value please reboot the system and try to update again from Windows Store.
