 Posted: Mon Oct 01, 2018 9:56 am Post subject: grub-install problem |
 |
|
Trying to install a new machine, and when i run:
| Code: | | grub-install --target=x86_64-efi --efi-directory=/boot/efi |
i get error:
"Could not prepare Boot variable: No such file or directory"
what can i do or check to resolve this?
/boot/efi seems to be mounted correctly and formatted as vfat:
/dev/sda1 on /boot/efi type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro)
efivarfs on /sys/firmware/efi/efivars type efivarfs (rw,relatime)
any help would be appreciated |

efibar version that installed, is: sys-libs/efivar-36
when tried to downgrade it to sys-libs/efivar-35 - grub-install seems to work correctly, without errors, but system couldn't boot.
upgrading back to sys-libs/efivar-36 - the same problem |

Hi,
can you check and show
| Code: |
efibootmgr --verbose

At what stage of boot system fails? Not bootloader found/grub fail/kernel fail?
Have you any OS except gentoo on you disk? |

Thanks!!
This (downgrading sys-libs/efivar from v36 to v35) was the solution for my recent "Could not prepare Boot variable: No such file or directory" -problem as well.
Lately I was not able to add new efibootmgr entries, apparently since upgrading to v36 (on Oct 22 of 2018).
After masking v36 and downgrading to v35 all is good again. |
