I got a problem after Windows re-install, I can't set up grub properly - it doesn't detect Kubuntu, whatever I did.
At first, system & partitioning: Kubuntu 17.10 Windows 8.1
Disks mode: GPT
- sda1 - don't know what it really is, Windows creates it automatically within installation.
- sda2 - EFI
- sda3 - unknown (Windows created this)
- sda4 - Windows
- sda5 - vfat /boot
- sda6 - luks - vg0 (root, swap)
So, I had Windows and Kubuntu 17.10 with manually tuned luks (Special Thanks to Encrypted custom install).
Everything worked well, before I did Windows re-install and erased grub.
I tried to chroot into broken system and re-install grub
/boot - sda5
/boot/efi - sda2
apt-get purge grub-common
apt-get install grub-common
apt-get install --reinstall grub-efi
grub-install --efi-directory=/boot/efi /dev/sda
update-initramfs -k all -c
update-grub
Grub is installed to /dev/sda with no mistakes, but update-grub fetchs only Windows EFI loader and doesn't recognize Kubuntu.
How can I fix it without Kubuntu re-install?
Thanks in advance :)
