And what is your partitioning and fstab? |
| 21 |
|
| 22 |
gummiboot wants all inside the ESP and this mounted at /boot: |
| 23 |
|
| 24 |
|
| 25 |
# grep boot /etc/fstab |
| 26 |
UUID=E004-1D89 /boot vfat auto 1 2 |
| 27 |
|
| 28 |
|
| 29 |
The gentoo GRUB2 wiki tells me to mount that at /boot/efi ... |
| 30 |
|
| 31 |
And grub2 fails to install now (with or without --boot-directory): |
| 32 |
|
| 33 |
# grub2-install --target=x86_64-efi --boot-directory=/boot |
| 34 |
Installing for x86_64-efi platform. |
| 35 |
grub2-install: error: cannot find EFI directory. |
| 36 |
|
| 37 |
I am *sure* that I have some crap in my ESP ... from my initial |
| 38 |
fiddling back then. |

I would appreciate any help to clean that up and get both gummiboot |
| 107 |
and GRUB2 installed as parallel UEFI applications. |
| 108 |
|
| 109 |
Currently gummiboot works very well! |

Thanks, |
