I could not find exact solution through the forum or internet. So posting my question here.
I have A dell Inspiron 5542. It came loaded with windows 8.1. (the dell site shows this when service tag is entered. but does not specify which version ? home/professional/enterprise and which English US or UK.)
I upgraded the windows to 10, when the upgrade from Microsoft was available. It went well.
But unfortunately I did not note the version of windows nor do I remember it.
There was a HDD crash later, loosing the version and the license key. The new HDD mounted, but not sure about which windows version to install.
Please suggest so that I can restore the OEM licensed windows 10 on the laptop.
The issues with installation media have been fixed with Windows 10 build 14393. The Windows 10 .iso will automatically input your Windows 8.1 Edition OEM key present in your MSDM ACPI table that's embedded in the systems UEFI BIOS. It will then automatically select the correct Edition of Windows 10 OEM to install. To Download the 14393 RS1 .iso follow my instructions here:
The Windows 10 14393 should automatically input Windows 8 OEM, Windows 8.1 OEM and Windows 10 OEM keys automatically and install the correct Edition of Windows 10. With the earlier Windows 8.1 .iso it was a case of trial/error. The correct .iso automatically input your product key the wrong .iso asked for a product key.
