[Solved] Separate boot partition and grub configuration

Hey!

I've been having an issue for a while now, and I haven't really found how to address it.

I have a separate /boot partition. It doesn't seem to be properly configured with grub.

When I update linux through pacman and reboot, it breaks my system because while a new version is installed, the system looks for module in the wrong directory (the one from the previous version).

I don't have an issue if after upgrading linux, I unmount my /boot partition and reapply the upgrade.

My fstab :

# 
# /etc/fstab: static file system information
#
# <file system> <dir>   <type>  <options>       <dump>  <pass>
# UUID=1e1ef087-2561-4900-8410-372353abf732
/dev/sda7               /               ext4            rw,relatime,data=ordered        0 1
/dev/sda8               none            swap            defaults                0 0
/dev/sda9               /home           ext4            defaults,noatime                0 2
tmpfs                   /tmp            tmpfs           nodev,nosuid,size=2G   0 0
/dev/sda5               /mnt/data       ntfs-3g         defaults                0 0
/dev/sda6               /boot           ext4                    defaults                0 0

My /etc/default/grub

# 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 `vbeinfo'
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 and set to the desired menu colors.  Used by normal and wallpaper
# modes only.  Entries specified as foreground/background.
GRUB_COLOR_NORMAL="light-blue/black"
GRUB_COLOR_HIGHLIGHT="light-cyan/blue"

# Uncomment one of them for the gfx desired, a image background or a gfxtheme
#GRUB_BACKGROUND="/path/to/wallpaper"
#GRUB_THEME="/path/to/gfxtheme"

# Uncomment to get a beep at GRUB start
#GRUB_INIT_TUNE="480 440 1"

#GRUB_SAVEDEFAULT="true"

Re: [Solved] Separate boot partition and grub configuration

What are the output of lsblk and sudo parted -l

(démarrage = boot)

EDIT : I've removed the bootable flag on /dev/sda2
The system has booted, and my guess is that it solved the problem. Will test soon and report back.

Yup, that did it!
