Hello there As the title says i have this assus pc where i replaced the motherboard and the old hd with a new ssd. The motherboard is the same brand assus and the same model class. The original hd had win7 professional installed and i cloned the partition on the new ssd. Aftern the motherboard replace i get 3 day to activate and if i try with the win7 key i get the 0xC004E003 error. Now before changing everything i saved the key with nirsoft produkey, and i have the "Windows (BIOS OEM Key)" also the win7 product key. On the original hd i dont have anymore the installation partition, but i should still have the recovery partition. My big question is there any way to activate with this keys kind of legally? Without using a loader. And without restoring and losing my current setup. Ps. I made the same changes on an identical pc months ago that had upgraded to win10 and i was abble to activate using the Windows (BIOS OEM Key).
