Random boot issue

[DanyBreizh]

Hello,
I have installed EndeavorOS after several years with Archlinux because I wanted to change my DE and to refresh my installation.
Everything is going fine excepted I have a random boot issue.
Sometimes it works fine and sometime I have this error :
error: no such device: b508d6f6-6135-4831-b1bf-3520a30f3008.
error: unknown filesystem.
grub rescue>

I have found a workaround, I use F11 on my MSI laptop and then I can select my boot device as EndeavorOS an then everything works fine.
The device with indicated error is my nvme disk with linux install.
I have to point-out that I have a dualboot installation with W11.
I hope somebody could provide me a tip to fix this problem.

error: no such device: b508d6f6-6135-4831-b1bf-3520a30f3008.

This appears to be the root device on the nvme device. I would do a disk check on the device and check any connections it has. This could be the sign of a failing drive or a bad connection.

The device with indicated error is my nvme disk with linux install.
I have to point-out that I have a dualboot installation with W11.
I hope somebody could provide me a tip to fix this problem.

can you recheck in your UEFI motherboard
save a profile pour windows ,then

for linux

• Secureboot off
• CSM off
• all disks on AHCI
• no legacy

[DanyBreizh]

I have check my nvme with Samsung Magician, no failure found.

[DanyBreizh]

Everything was working well since 5 years. I have made no change in the UEFI motherboard, just a new fresh install with KDE as new DE.

[keescase]

Not by far being a expert on this I noticed that your efi partion is 96% full.
That seems a bit to much for good measure, also I noticed you have grub 3 times , that seems a bit strange too.

[latisullivan]

I am quite the noob as well, meaning I have made many mistakes throughout the years on my Linux ride. So I might not be able to explain something, but maybe I can point in the right direction (hopefully!).

Following up keescase’s reply, I am a bit confused as to what I am looking at on your lsblk output.
I might be entirely wrong, but it feels like you have your EFI partition for both OSes on the same drive, and on top of that is the Windows drive. Did you make sure to install Windows after Linux or are you sure you configured it correctly? I have a slight feeling that could cause trouble, maybe. Windows is a bit of a rascal

Edit: I forgot to ask/mention - When you mention your F11 UEFI/BIOS solution - does this mean you have to manually go in and select it every time for it to boot correctly (as if it wasn’t default) OR do you mean that it stays as default but then randomly breaks? It could also be something to do with GRUB maybe.

That said, not too long ago I was dual booting as well, but dumb-past-me forgot to unplug one of the SSDs when installing each OS, so everything was fine but the EFI stuff was shared as well and when I tried to format and reinstall… I nuked the EFI and couldn’t restore it so had to end up reinstalling EnOS completely - this time with the other (windows) SSD unplugged! Now everything is separated and balanced, as all things should be

Hopefully you can solve this without too much hassle.

I would run a check disc in Windows for errors on the disc since i see this.

[DanyBreizh]

I have the same conclusion as yours, it is a grub issue.
My next step is to search how to delete and create a new grub.
The 300Mo came with the original efi partition with Windows7 when I bought this laptop.

I have installed EndeavourOS in replacement of an old arch installation.
It seems that during the grub installation, EndeavourOS created a new grub without replacing or updating the previous one.

[keescase]

Well it makes sense that eos would have created a new grub , because it uses a different path then the other two grub files. You could delete the other 2 grub files if they are not in use and free up some space. If I can make a suggestion , and it is not to much of aproblem, you could reinstall Eos and create a new EFI partition ,using the installer , so your efi parttition wil use the nvme, which probably also speed up things a little bit at boot.

[DanyBreizh]

I have reinstalled eos, deleting old grub, and I still have this randomized issue, sometimes it boots, sometimes not.
My msi laptop is from 2019 and does not support efi partition on the nmve.
Did I still missed something ?

[keescase]

Can you share some information about your system by typing the following command.

inxi -Fxxc0z

Please put the output in a “box” by using the </> , that would make it a bit more readable.

@DanyBreizh

sda1 vfat FAT32 SYSTEM D45A-0097 12,6M 96% /boot/efi

the size for /boot/efi is too small ( around 100M to 300M )

[DanyBreizh]

Yes I know but there is a “Microsoft reserved partition” just behind which is not movable.

Hi,
It seems that my issue has been solved by diactivating the fastboot in the bios.
Thansk you for your support.
