[EN] [Solved] Stuck into bios (uefi)

[jyp]

After hundreds of successful DU, the last one yesterday seemed ok as usual. But upon reboot, I am stuck in the bios configuration screen and I cannot find any clue about how to fix that problem.
Any advice would be welcome. Thank you.

After hundreds of successful solutions ...
One possible way to solve the problem:

1. siduction Live System starten
2. chroot-helper starten
3. im nun folgenden terminal folgendes eintippen:

Code: [Select]

grub-install
update-grub
exit
Nun Rebooten und es sollte wieder funktionieren.

• Download the latest iso of siduction
• Copy the iso on to a usb-stick.
• Boot the live system.
• Start the chroot-helper.
• Select the device and partition you want to chroot. Then:

Code: [Select]

grub-install

Code: [Select]

update-grub

Code: [Select]

exit

• Reboot your system.
• For the future: Read the upgrade warnings!

Thank you for the feedback.
I usually read the warnings but I confess that this time I went over them too fast and got bitten. My bad.

Working on the matter now.
Thanks again.

Lack of knowledge 

After launching chroot helper

• "Choose the hard disk to be examined": _nvme0_ (samsung ssd 970 evo)
• "Choose one partition for chroot": _nvme0n1p2_ (ext4 117G)(that is where the system is installed)
• root@chroot-helper: /# grub-install
  grub-install: error : install device isn't specified

I tried to cd into the grub folder and run the command again but no success.
Thank you for your patience.

Shame on me.

Everything is ok now.
The culprit was the CSM setup in the bios.

Sorry for taking your time.
