Dear community members
I recently replaced my laptop's hard drive and installed a cracked version of Windows 10. Now, I need to downgrade to Windows 8.1, and I've downloaded the Windows 8.1 Disc Image (ISO File). However, I'm unable to install it without a key, even though I have an OEM key.
Could anyone guide me on how to proceed with this downgrade? Additionally, does anyone know where I could download the Windows 8.1 RTM Core Single Language OEM:DM version?
Your help would be greatly appreciated. Thank you !

Hi:
You need to download the W8.1 SL 64-bit ISO file from the link below and it should automatically work with the W8.1 SL product key in your notebook's BIOS.
It's the last file to select from the drop down list.
Download Windows 8.1 Disc Image (ISO File) (microsoft.com)
Then use the free Rufus utility to transfer the ISO file to a USB flash drive so that it is bootable.

Set up the Rufus program exactly as you see it in the illustration for Windows installations.
