New install of Mag10 Beta1 leaves Grub in rescue mode

[banjo]

I just installed Mageia 10 beta1, and when I reboot the computer it leaves Grub in rescue mode. Here is the error.

Code: Select all

error: ../../grub-core/kern/d1.c:456:symbol `grub_cli_set_auth_needed' not found.
Entering rescue mode...
grub rescue>

I installed this on a computer that was running Mageia9. During the installation I told it to use the existing partitions. I mostly accepted the defaults during the installation. It connected with my WiFi successfully and did the updates.

I am over my head with how to deal with grub rescue mode.

Any help would be appreciated.

Thanks

Hi Banjo,

Install ISO was "Mageia-10-beta1......" ? please fill the blank.
Install media was: USB, Optical, ISO-on-partition?
If a CI install, which DE(s)?

did you note any install errors, especially during the grub installation part?

A quick "google" suggests that resetting the grub boot delay to greater than 7 sec may be a fix (!)
so can you do a dirty re-install ( i.e. custom disk partitioning, do not format the partition(s) ) and at the configuration window, change the grub settings.

Some basic information on that box might be helpful.
Is this legacy BIOS or UEFI boot? What type of disks/controller do you have Mageia and/or grub on?

In rescue mode you can use basic grub commands to see what disks grub sees, and also if it can see the files. You could even manually boot your install that way if you're interested.
See e.g. https://www.linuxfoundation.org/blog/bl ... 2-on-linux

For some background what the error message means and what probably caused it check https://forums.opensuse.org/t/grub-is-c ... /185887/12

Sorry about the lack of details.

I installed from the Plasma Live iso, Mageia-10-beta1-Live-Plasma-x86_64.iso. The live iso booted just fine.

I did not see any indications of failures during the installation.

The grub time delay was left at the default 10 seconds. The only change I made to grub was to set it to use text output instead of graphical.

Here is the output of an old inxi from when it was running Mageia 9

Thanks for the links. I will go study the commands and see if I can trouble shoot the problem some more.

The live iso booted just fine.

Well the live iso does not care about your installed bootloader at all

[banjo]

I totally agree. But it does demonstrate that the hardware is working and able to run Mag10.

I booted into grub rescue and tried some of the suggested commands.

(hd1) is another disk in the system that just has data on it. I don't know what (hd2) is. The thumb drive is not attached to the system.

After entering the command

Code: Select all

ls (hd0, gpt2)/


the system hung up and stopped responding to the keyboard. No output was created. That makes continuing to trouble shoot more difficult.

I also tried ls (hd0,gpt2), ls (hd1,gpt1) ls (hd0,gpt1) and all of them hang up.

Is there any value in booting the live Mag10 and looking at it from there?

I would suggest boot with the classical ISO and choose Rescue, then reinstall grub.

I have not tried that before. I will download the ISO and give that a go.
Thanks
