Hello everybody,
The installation procedure provided in this site says :
"Look at the product ID at the bottom and see if the product ID mentions the words OEM. If the license is OEM then your product key will reside within the system UEFI/BIOS known as a System Locked Preinstallation (SLP) key. If you have a supported OEM Edition proceed to Downloading a Windows 8.1 with Update 2 .iso."
However in my case, my product ID well contains the words OEM but the installation procedure (from Windows 8.1 with Update 2 .iso) doesn't retrieve it and ask me to enter the key manually and as everybody knows, the windows key is definitly not provided by Dell.
Can somenone tell me what is the solution to perform a clean Windows 8.1 reinstall on my XPS8500 ?
I must precise that my Dell runs actually Windows 10. I want to downgrade to 8.1.
Thanks for any reply.
HL.
