Windows 10: Activate Windows 10 clean installed using upgraded serial key

I have upgraded my Asus Zenbook UX303LN to Windows 10 single language and have recorded the upgraded serial key using windows serial viewer. Yesterday I unintentionally did something that cause my notebook can not boot properly. I tried to repair and recover the OS but it said that the reparation and recovery failed.

I tried to do clean install using USB booting. However, when the upgraded serial key didn't work for installation and activation. Anybody can help me to solve why the upgraded serial key doesn't work for clean install?
thx.

:)

 

Can I use my upgrade serial number to install from an ISO file?

You do not need a serial if you have first upgraded AND activated win 10. Should you need/want to do a clean install from ISO you can simply skip the step where it asks for a serial/key and it will check with the activation servers to verify the install
is genuine.

 

Clean Install after redstone update

Hi,

I installed clean version of windows 10 using my windows 7 serial key. I've heard the free upgrade to windows 10 will end on July 29 and a big update is coming on August 2.

Can i install a clean version of Windows 10 after the big update using my windows 7 serial key?

 

It did work for me on a clean install of 10 with a iso.

 

Hi farid, welcome to Ten Forums. Since you already had windows 10 installed via an upgrade you do not need to use a key when you reinstall. When you get to a screen that asks for a key during installation choose "skip" in the lower right hand side. When you are installed it will activate automatically. This is called a "digital entitlement".

 

Hi, I did fresh install instead of reset OS and it didn't work for me *Sad

 

Thanks John for the response.it
The story started when I added additional half size msata SSD to my zenbook and cloned the upgraded windows 10 from the original 1tb HDD. I need to clean reset the OS and got fail several times. I decided to do fresh install. When it was asked to fill the key, I wrote the upgraded serial key and not work. I choose to skip the key and activated using the upgraded one again.... and it didn't work again *Sad

I am thinking to do reset to factory default (windows 8.1) again and re-upgrade again, but afraid to fail... again and again...

 

Hi farid, I used the upgrade key on the ISO version 10240 downloaded from the MS site Clean install and worked fine. Where did you get yours, is it the recovery image usb?

 

farid, you probably installed the wrong edition or language of Windows 10. Run showkeyplus from this forum and it will tell you if you have a Windows 8 product key stored in bios and what edition/version of Windows 8 it is for. If you install the current (version 1511, build 10586) Windows 10, with the matching language and edition, it will not ask you for a product key because it will install and activate by reading the Window 8 product key stored in bios.

SonicBlue and NavyLCDR, Thanks for the guidance. I put my notebook to ASUS service point for windows 8.1 recovery... I will report the result after upgrading again to Windows 10.
