As part of the procedure of converting the root filesystem of my computer to btrfs, I chrooted into it and reinstalled grub. Followed this guide: GRUB/Restore the GRUB Bootloader - Manjaro .
I also removed and installed some kernels, using pacman (mhwd-kernel didn’t work in chroot), and did mkinitcpio -P and grub-mkconfig.
Removed two dkms modules that were causing issues, anbox-ashmem and anbox-binder.
More info about how I got in this situation in my previous forum post.
Now, booted into the actual system, new kernel images are installed into /boot, but grub only shows the kernel images located in /boot/efi/.
I am unable to boot from any kernel images apart from the ones located in /boot/efi/
What should I do to restore regular system functions, i.e. boot from the newest installed kernel?
test -d /sys/firmware/efi && echo efi || echo bios
efi
cat /etc/default/grub
GRUB_DEFAULT=0
GRUB_TIMEOUT=1
GRUB_TIMEOUT_STYLE=hidden
GRUB_DISTRIBUTOR=“Manjaro”
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash loglevel=3 sysrq_always_enabled=1 udev.log_priority=3”
GRUB_CMDLINE_LINUX=""
If you want to enable the save default function, uncomment the following
line, and set GRUB_DEFAULT to saved.
#GRUB_SAVEDEFAULT=true
Preload both GPT and MBR modules so that they are not missed
GRUB_PRELOAD_MODULES=“part_gpt part_msdos”
Uncomment to enable booting from LUKS encrypted devices
#GRUB_ENABLE_CRYPTODISK=y
Uncomment to use basic console
GRUB_TERMINAL_INPUT=console
Uncomment to disable graphical terminal
#GRUB_TERMINAL_OUTPUT=console
The resolution used on graphical terminal
note that you can use only modes which your graphic card supports via VBE
you can see them in real GRUB with the command ‘videoinfo’
GRUB_GFXMODE=auto
Uncomment to allow the kernel use the same resolution used by grub
GRUB_GFXPAYLOAD_LINUX=keep
Uncomment if you want GRUB to pass to the Linux kernel the old parameter
format “root=/dev/xxx” instead of “root=/dev/disk/by-uuid/xxx”
#GRUB_DISABLE_LINUX_UUID=true
Uncomment to disable generation of recovery mode menu entries
GRUB_DISABLE_RECOVERY=true
Uncomment this option to enable os-prober execution in the grub-mkconfig command
GRUB_DISABLE_OS_PROBER=false
Uncomment and set to the desired menu colors. Used by normal and wallpaper
modes only. Entries specified as foreground/background.
GRUB_COLOR_NORMAL=“light-gray/black”
GRUB_COLOR_HIGHLIGHT=“green/black”
Uncomment one of them for the gfx desired, a image background or a gfxtheme
#GRUB_BACKGROUND="/usr/share/grub/background.png"
GRUB_THEME="/usr/share/grub/themes/manjaro/theme.txt"
Uncomment to get a beep at GRUB start
#GRUB_INIT_TUNE=“480 440 1”
Uncomment to ensure that the root filesystem is mounted read-only so that
systemd-fsck can run the check automatically. We use ‘fsck’ by default, which
needs ‘rw’ as boot parameter, to avoid delay in boot-time. ‘fsck’ needs to be
removed from ‘mkinitcpio.conf’ to make ‘systemd-fsck’ work.
