GRUB2 on LVM - Defaults to CLI, No menu.

I am setting up Slackware64 14.2 on an SSD using LVM and GRUB. When I reboot the system it takes me to GRUB cli. I can boot to my install just fine, but have been unsuccessful in getting a menu to display or even booting directly into my install.

Insights appreciated.

Thanks.

What did grub-mkconfig output?

I blindly ran boot-repair-disk.iso on a 'broken' slackware14.2 & it 'auto-magically' fixed it!
IF it can connect to the internet, it will post 'all the info anyone could ever want' mine/mine

*sigh*

The output of grub-mkconfig is also what is written in /boot/grub/grub.conf, since you told grub-mkconfig to put it there.

Could we see that bit, too?

EDIT: Now that I think about it, does your box use UEFI or BIOS boot? If the former, I won't be able to help since none of my motherboards are UEFI, but I believe that you have to do something different with the conf file in that case. Hopefully someone will chime in if that's the case.

Hey, you used my script!

Those entries should work. I don't boot directly from an LVM volume; I still use an ext2 partition. Nonetheless, the menu entries should show up.

You should look at https://help.ubuntu.com/community/Grub2/Troubleshooting and see if that helps.

Looks like gpt (with BIOS, not UEFI) - you need to create a bios_grub partition (0xEF02 partition type).
Then grub-install again to write the core.img properly.

According to the Ubuntu link grub cannot find the config file.

This is my prompt

Code:
grub>
prompt: GRUB 2 loaded modules but was unable to find the grub.cfg file.

I found my issue. My grub.cfg was named grub.conf. I simply renamed the file and it works. Thanks for you help. That grub troubleshooting link was very helpful. I did you use your script.

Sweet! I'm glad that your menus and stuff show up now.

EDIT: Hey, I wasn't trying to shame you into admitting that you used my grub script. I was just happy that someone was using it.
