I am facing an issue with Grub2 when using UEFI.
It is working well on legacy support but I need it to work on UEFI.
I only need it on USB to boot WIndows 8.1.
I only have one O/S installed. Only Win8.1
I does not load into the Grub menu.
I tried many versions of Super Grub2 -EFI and all gave the same error.
I get the “Welcome to Grub!”
Then repeated message error: Unknown filesystem
The it goes to rescue mode.
I tried ls with all the partitions and nothing happened.
How can I fix it?
