here is a bit of the sequence of events:
I have a laptop that came preinstalled with Windows 10. I installed Arch Linux (through Antergos) and dual booted successfully with no issues for some time.
I then downloaded and installed Ubuntu 18.04 to some free space on my drive, and reboot (using the UEFI boot selector) into Arch Linux to upgrade grub using:
grub-mkconfig -o /boot/grub/grub.cfg
I reboot once more and discover that I am in Ubuntu's grub selector. I am unable to boot into Arch Linux due to a kernel panic, but Ubuntu and Windows 10 are available and boot just fine.
In an attempt to get Arch to boot, I run the following inside Ubuntu but to no avail:
I intend on keeping Arch as my primary distro (for learning purposes), but need to do some work on Ubuntu, so I'd prefer to stick with the Antergos grub selector.
I am still able to boot into Arch using the UEFI boot selector, and this takes me into my Antergos boot loader which successfully detects and boots all three OS on the system.
I'm sure this is a fairly simplistic solution I just haven't been able to Google properly and need to proceed with some work I have to do. Any help would be greatly appreciated.
Thanks in advance!
