I've written a short, experts-only article about using VirtualBox raw disk access feature to allow installations on a system with read-only NVRAM that prevents any use of external installation media. Nerdy, dangerous, fun. Take a look. https://www.dedoimedo.com/computers/uefi-nvram-ro-installation-workaround.html Cheers, Mrk
Hi, i was unable to write new uefi enteries on a windows tablet after couple of years of use, not sure what was the reason. I updated the uefi BIOS but the issue persisted. I tried easyUEFI tool's Clean Up function and it fixed the issue. Can you give it a try?
