How can I edit that file so that it points to fs0:\efi\boot\bootx64.efi
?
The following is just for Win10.
Starting Linux with the UEFI shell is more complicated.
I haven’t found a good tutorial about the startup.nsh file structure.
Maybe try batch file syntax?
You just put the code above in the directory: fs0:\efi\boot\
You can navigate there like:
fs0:
cd efi
cd boot
edit startup.nsh
If that directory structure isn’t there, try the other fs1 to fs? .
Yes, the UEFI shell has some things built in:
help -b
shows all the things that are built in.
Hope that helps some people.
