Kernel Panic on 7.0.0.30

[Jebry]

I keep getting a Kernal Panic when I boot my PC. when I hit the reset button I can select 7.0.0.28 which loads without an issue.

I've tried using Sudo nano/ect/default/grub and changed GRUB_DEFULT=0 along with adding GRUB_SAVDEFULT=true as all the help I can find online points me this direction to boot a specific kernal; but the same issue keeps happening.

Any helpful advice would be great. This is very annoying and has had me thinking about returning to Windows as day by day I feel like I'm over my head using Linux.

It's strange to me that I've seen so many people having issues with 7.0.0.28 but none with 7.0.0.30

Welcome to the Forum!

You did already the first very important step:
you are able to choose the linux kernel which is working for you so that your PC is starting with linux kernel: 7.0.0-28-generic

To implement the older kernel 7.0.0-28-generic permanently please follow this Forum Tutorial from @Aravisian. It starts with booting with the older kernel:

[HOW TO] set an older kernel to default boot

You may need to use an earlier kernel than the current kernel used by Zorin. This method allows you to set the kernel that you will boot into by default. To set the new kernel to default: Boot into the kernel you wish to be Saved. Open terminal and run: sudo nano /etc/default/grub Change GRUB_DEFAULT=0 to GRUB_DEFAULT=saved Hit enter to drop down a line. Add GRUB_SAVEDEFAULT=true ctrl+x to exit, then the y key to say yes to save, then the enter key to save as current configuration. Ru…

To avoid typing errors use "copy and paste" from the tutorial for the Terminal commands and for the Editing of the grub config file.

And at the end don't forget the command sudo update-grub

Please post here the content of your grub config file with the Terminal command:

sudo cat /etc/default/grub

If the work around is applied, then what happens when the next version of the kernal is released? Will the newer version be used or will the older version continue to run at startup?

[JustZorin]

If as above in the tutorial the /etc/default/grub file includes:
GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true
and it was enforced with sudo update-grub
-> then a linux kernel update doesn't replace the implemented older kernel.

But if this older kernel gets purged manual or through apt autoremove,
the newer kernel will be implemented during next linux kernel update.

To check, if the older kernel is still existing use:

grub-editenv list | grep saved_entry

Ok. Thank you. Will have to take a closer look at the details.

The kernel updates will not change the kernel if you have set an older kernel as saved.

After the next kernel update, go to the "Advanced options for Zorin" in grub menu and select the latest kernel to test it. If ithe new kernel works, you can change the line in your /etc/default/grub file to
GRUB_DEFAULT=0, safe the file and run sudo update-grub. Then your system will automatically boot with the latest kernel after kernel updates.

If the new kernel doesn't work well and you want to stay with the older kernel, keep the grub file as it is with
GRUB_DEFAULT=saved and go again to the "Advanced options for Zorin" and select the older kernel you had set before. This kernel will then be the default kernel to boot until you change it.
The kernel which is in use will not be deleted by the command sudo apt autoremove.
