[SOLVED] Stuck with GRUB promp after install

[egabo]

Hello,

I ran into this issue when I installed Mageia 8 64-bits version, boot process stops and shows this:

error: file '/grub2/x86_64-efi/normal.mod' not found.
grub rescue>

After checking on my partition where I did the install, I saw that the directory /boot/grub2/x86_64-efi was indeed missing. So I tried to do the install with the Live version instead to no avail. Here's how I solved it:
- booted in recue mode using my Mageia 5 install DVD
- mounted my Mageia 8 partition (/dev/sda7)
- mounted my backup copy of Mageia 5 (/dev/sdb2) -- yeah, I tend to do a full backup before messing around
- copied the missing directory from /dev/sdb2 to /dev/sda7
- rebooted and voilà!

As soon as I got access to KDE, I found out that the package "grub2-efi x86_64", which contains that directory along with the files, had not been installed. From that point, I deleted the one I had copied from my backup and proceeded to install the package. All is well that ends well I guess.

Have any of you run into this? Should I write a bug report for this?

Glad you solved it.

Was this a fresh install?

Did you boot the installer in EFI mode?

Yes it was a fresh install.

I rebooted the installer and found out that it was not in EFI mode, due to CSM compatibility mode being enabled in the BIOS. So basically, I am the cause of that whole situation.

I will mark this as solved, and hopefully this topic will be useful to some poor soul like me.

Great then

Yes automatics and compatibilities are good together to screw up things (Says me who repair old industrial automation systems.)
