Windows 10: Windows 10 to Launch on USB Sticks Too

If you're just running setup.exe from a running Windows install, your not booting from the thumb drive. That's why just copying the files to it works. If your in Windows 8 just mount the ISO and run setup.exe. You don't even need a thumb drive. Take that same thumb drive and try to make your computer boot from it and see what happens. Like you would do if you had a brand new blank hard drive with no OS on it and wanted to do a clean install.

 

I've clean installed Win10 about 30 times during testing using this method on my laptop in UEFI/GPT. Note it's a Win7 laptop and doesn't have secure & fast boot.
On my Win8.1 desktop I haven't tried it. Maybe like posted earlier it depends on the BIOS that one has. At least on older machines it works. What's that term I see so often here... YMMV*Smile.

 

Using which method? Just running setup.exe from Windows?

 

Booting to USB and clean installing.

 

Also I have been able to use same USB for DISM source with no ill effects.(Needed to activate :NET 3.5 and once to repair something)

 

Ok, just wanted to verify, thanks.

 

No problem alpha*Smile. Like I said it could just be my laptop as I haven't tried on my desktop, so I still my need diskpart or rufus later for a clean install. My laptop by the way doesn't have a "Real UEFI" BIOS more like a EFI option if you know what I mean(Don't know how to describe it better).

 

My ASUS laptop is UEFI but being a laptop, the BIOS is very limited in terms of options. Doesn't look any different to any other BIOS I've seen other than the Secure boot etc options.
