Corruption of debian kernel 6.1.0-14 and return to the 6.1.0-13

Hello everybody

I updated the kernel of my Q4Os distribution 3 days ago, I went from kernel 6.1.0-13 to kernel 6.1.0-14.
However, the Debian community announced a few hours later that this kernel contains a big flaw, and that it risks  to corrupt data.  As my computer has all my data, I would like to go back to the previous kernel. 
I would like help rebooting to the old kernel that is still installed please.  When I run grub I can't access the advanced options.  When I run the command
sudo grep '^menuentry' /boot/grub/grub.cf, I only see one entry for Q4OS, and no kernel choices. (see picture)
I would like to point out that I installed Q4OS with the Windows application from your website.
How can I boot on a different kernel than the default one?

I thank you in advance for any help you can give me
Good evening
Tom

Strange that you have not the 'advanced options for Q4OS' entry not present in grub menu.
Did you try rebuilding grub menu with sudo update-grub command ? and what does the output looks like ? You should have something like that for example:
[...]
Found linux image: /boot/vmlinuz-6.1.0-13-amd64
Found initrd image: /boot/initrd.img-6.1.0-13-amd64
Found linux image: /boot/vmlinuz-6.1.0-10-amd64
Found initrd image: /boot/initrd.img-6.1.0-10-amd64
[...]

(sorry I can't see the pictures you posted, don't know why)

another thing to check, what do you have in the folder : /etc/grub.d/   ?

Yes i don't know why we can't see pictures but it's not very important

Yes i try sudo update-grub command, the output is

Generating grub configuration file ...
Warning: os-prober will be executed to detect other bootable partitions.
Its output will be used to detect bootable binaries on them and create new boot entries.
Found Windows Boot Manager on /dev/nvme0n1p1@/EFI/Microsoft/Boot/bootmgfw.efi
Adding boot menu entry for UEFI Firmware Settings ...
done

thank you for your answer!

- 20_linux_xen
- 30_os-prober
- 30_uefi-firmware

You only need to update your system and reboot to get fixed kernel 6.1.0-15

If you want to get boot grub menu, edit file "/etc/default/grub", configure lines:

GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=4

Run in terminal:
$ sudo update-grub
and reboot

Re: Corruption of debian kernel 6.1.0-14 and return to the 6.1.0-13

Thank you very much
I just did the update, everything went well

For the grub menu, when I boot i can see the menu but I can't choose a different kernel.
I checked, the lines in the file /etc/default/grub are there.
Anyway the problem is solved so it's less important but if you ever have another idea, out of curiosity...

Q4OS is an awesome distribution, thanks for your work!

How did you install Q4OS? Installation media file name?

By the way, you can attach screenshots and other files up to 300 KB directly to the forum post.

Re: Corruption of debian kernel 6.1.0-14 and return to the 6.1.0-13

I installed q4os using the Windows application that I downloaded from your website. So I still have windows 11 on my PC
Q4OS Aquarius, WinSetup.exe - 64bit / x64
I don't know if this is useful but my desktop environment is Trinity

My PC is an HP Pavilion Gaming, Ryzen 5 processor, Nvidia geforce GTX

Ok for the photos, thank you!

Unfortunately, Windows installer suffers from this shortcoming, so you cannot choose another then the current kernel at boot time. It's on our todo list.

You are welcome If you would still need for some reason to boot another then the default kernel, you can manually update symlinks /vmlinuz and /initrd.img to point them to the alternative desired kernel and reboot subsequently.
