Hi10 plus z8350 version ... linux mint 18.2 .. can get as far as grub installation when this message appears
"Grub installation failure .. The 'grub-efi-amd64-signed' package failed to install into /target/. .." etc
I have deleted remix and windows and have a linux partition, a swap partition and a boot partition (eps and boot flags)
Linux runs fine from the usb but refuses to install onto the internal flash.
I have fiddled a little with the bios security settings without success.
The bios is PID6_C189B_Hi10_plus.236 13 march 2017. Is this the z8300 bios?
I also note you need a password to access the z8350 version of android from the chuwi download site .. what is the password?
