Add the Windows 8.1 Enterprise 90-day Evaluation ISOs to Easy2Boot

If you copy the Windows 8.1 Enterprise 90-day Evaluation ISO to your Easy2Boot \_ISO\WINDOWS\Win8 folder of your Easy2Boot USB drive and try to install it, you will find that you will receive a pop-up error message which reads 'Windows cannot find the Microsoft Software License Terms'.


This is a sign that the product key chosen by you, and subsequently written to the AutoUnattend.xml by Easy2Boot, is missing or incorrect.

Although this version does not require the user to enter a Product Key when installed from a DVD or from a 'flat-file' USB drive, to get these ISOs to work in Easy2Boot, you need to use the product key that is embedded inside the product. To find out what the product key is, you can install it to a VM from the ISO file, or use RMPrepUSb to extract the ISO to a USB drive and install it to a real system. Then run the Magical Jelly Bean KeyFinder to find the Product Key. In the case of Windows 8.1 Enterprise 90-day Evaluation it turns out to be 76FKW-8NR3K-QDH4P-3C87F-JHTTW.

We can now either create a .key file in the \_ISO\WINDOWS\Win8 folder for this key (copy an existing example file and modify it), and/or add it to the CHOOSE FROM A LIST.key file (in both the menu and the place where the variable is set).

E2B version 1.20 will contain a key file for Windows 8.1 Enterprise 90-day Evaluation.

P.S. Use the command slmgr -rearm from an Admin command console to get an extra 90-days when your first 90 days expires.

As an alternative, you can convert the ISO to a .imgPTN file using the MPI Tool Kit. If you use the MPI_FAT32 shortcut, then it will also be UEFI-bootable too.
