fedora 23 grub boot options

hello, so i installed F23 on this T410 thinkpad.

Installation went super smooth, but i accidentally pulled the thumbdrive at "reboot and start using your system", before i could click the reboot button.

While trying to boot back up i had 2 options, install and rescue like normal. Whenever i tried the normal option i would get a kernel panic and the system would hang. After powering off i chose the rescue option not quite knowing what to expect.

System booted normally, did a restart and was able to boot into the normal option.

So here is my issue. Yesterday i got my replacement battery for this laptop and i have been doing "acpi" at command prompt to make sure all is good with it. this morning i unplugged the power cable cause i was at full charge, ran acpi it said "98%" and all of a sudden the laptop powered down.

havent checked logs yet as i notice i now have 4 options in grub and it looks like i am defaulting into fedora + debug, and im not sure if this is normal

attached is a picture, can anyone give me insight as to if i need to update grub, just leave it alone, would logs tell me why it just powered off like that?

I don't use Fedora so I'm not sure what you would expect. I doubt that a debug option is the default. The other options look standard, two different kernels in the 2nd and 3rd option and there is usually an option for recovery or rescue. If it is working and you want to default boot to the second option, open a terminal as the root user, open a text editor and change the line below in /etc/default/grub:

Replace the "0" with a one. I don't often use laptops but I always shut down before unplugging although I have no idea if that is part of the problem. Are you still able to boot and use the system?

hello, thanks for the reply. i guess i could start shutting down before unplugging if it becomes a problem.

upon further inspection of that picture i did notice that the kernel versions were different. but once i booted into the correct one(without debug) that is now at the top of the list whenever i reboot. I am not sure if it remembers the last option or whatever, but i am not going to worry about it too much as it is running with no issues.

again thanks for the response
