Hi cl-Albert
Thanks again for you investigation.
If we run the setup in Windows, it's the same. After a reboot it switch back to W10-Home
And unfortunately for upgrade the system to W10 pro you cannot use OEM key.
Upgrading with Store is not possible, because the License is in that case bound to an Microsoft Account.
So, we made some excurse in UEFI, bootoptions, Microsoft, and reading lots of forumposts...
😕The solution (if some others have that problem):
You need:
- USB-Flashdrive
- W10pro DVD or .iso
- Rufus
BEFORE START - MAKE BACKUP - IF YOU HAVE NO IDEA, WHAT YOU DO - DON'T DO IT.
You will erase the existing installation - secure the folders like cl-Albert wrote before!
1.) Extract W10 Installation Media into a folder or Copy all from Install-Media in that Folder.
2.) Add a File in /sources called ei.cfg
Edit File with Editor:
[EditionID]
Professional
[Channel]
Retail
(=> here we fix Editon to PRO)
3.) add a File in /sources called PID.txt
Edit File with Editor:
[PID]
Value=XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
(=> THIS WILL BE THE OEM SERIAL OF W10PRO and override embedded W10Home)
4.) get software Rufus
https://rufus.ie Install or use portable
5.) Put in a usb-flashdrive
Run Rufus
Drive: pick the usb-flashdrive
Klick on advanced settings
Start: UEFI:NTFS (you must use first advanced settings, then you can pick this )
Format: Give the usb-flashdrive a name
Run START
6.) Copy after it finished ALL files from the first created folder of W10 Install Media on the usb-flashdrive
7.) Override autorun.inf if asked
8.) Boot ASUS with hold F2 to BIOS
9.) disable secure boot and fast boot - see pictures at startpost
10.) select usb-flashdrive for boot
11.) do the installation
12.) enable secureboot and fast boot again
With this setting you can override UEFI embedded key.
Here some good links, for explaination.
important; you cannot use Fat32, because two files are too big for that... and Win7 Boot Tool isn not recognised in ASUS Boot.
