Once downloaded install the update and windows should activate automatically

The instructions in these articles don't work the installation will always ask for a key and when you call Dell to ask how to do it they tell you to follow the instructions in these articles.

According to these 2 articles from both Dell and Microsoft this is possible: (I recommend making a backup of the entire /boot/efi directory tree that way you can restore it if you make a mistake.We are switching our environment from windows 7 to windows 8.1 and I have a bunch of Dell computers I need to roll out with windows 10 pro keys in the bios that I have to install windows 8.1 pro on. efi files from the /boot/efi/EFI directory tree in Linux and/or by using the dont_scan_files and dont_scan_dirs options in /boot/efi/EFI/refind/nf. The trick is then to clean up the unwanted boot entries, which you can do by deleting. If you can boot both Linux and Windows, install the rEFInd Debian package in Linux.Īt this point, rEFInd should come up as your primary boot loader.Some of these options will bring you to your non-functional grub> prompt, though. With any luck, at least one Windows option and at least one Linux option will work.

(You'll probably see multiple options for each OS.) With any luck, you'll see the rEFInd menu with options for Windows and Linux.
