1.chroot /mnt
2.grub-install --target=x86_64-efi --efi-directory=/boot/efi/ --bootloader-id=manjaro --recheck
Show error " installing for x86_64-efi platform

grub-install: error: efibootmgr failed the boot entry; no such file or directory.
When you get this error

run
sudo modprobe efivarfs

Where should I see?
I made a mistake deleting the entire boot partition
I had just copied it before
I paste
When boot laptop
After password grub partion just show
“UWFI Firemware settings”
Virtualization is enable bios
What are the symptoms?
How do you know that it is broken?
I ask because
just yesterday
after some updates
I rebooted my laptop.
I could not type the password for my encrypted drive.
It was as if there was no keyboard input possible.
It turned out to be a missing
keyboard
hook
in /etc/mkinitcpio.conf
I never had it in there - and it still worked flawlessly until yesterday.
After the last update I did - it no longer worked.
I chrooted,
added the
keyboard hook
re-generated the initrd
and all was good again.
If this is your symptom, this is the possible fix.
I know the drive password and I have no problem with it
By mistake I deleted the entire contents of the boot/efi partition I had copied and then just paste then broken grub
ok
it was a possible scenario.
It definitely caught me by surprise.
It always worked - but then it suddenly didn’t anymore.
… because of a missing “keyboard” hook that was never present before.
Friends, does anyone have a solution?
Will my Linux settings be compromised if I reinstall?
I add this command
1.mount -t efivarfs efivarfs /sys/firmware/efi/efivars
2. 1. grub-install --target=x86_64-efi --efi-directory=/boot/efi/ --bootloader-id=manjaro --recheck
3. Installation finish. No error reported
4.grub-mkconfig -o /boot/grub/grub.cfg
5.
Not add win10 and manjaro!!
what is the problem ?
Thank you for your help
for win 10 , os-probe is desactived by default , if you need
`echo GRUB_DISABLE_OS_PROBER=false|sudo tee -a /etc/default/grub && sudo update-grub`
check for efi
sudo efibootmgr -v
