I understand it has to do with the Grub settings. I followed the instructions as listed in this vod to the letter and am currently in Hardened Kernal but cannot seem to use the same instructions to switch over to the Zen Kernel type.
I’m sure it’s a separate option on the GRUB interface within terminal unless there another way to switch it on bootup. Any advice is greatly appreciated.
So…after following advised steps no luck. The sub menu from which I could select between different kernels isn’t popping up. Here’s my GRUB settings.
# GRUB boot loader configuration
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 nowatchdog nvme_load=YES"
# Preload both GPT and MBR modules so that they are not missed
# Uncomment to enable booting from LUKS encrypted devices
# Set to 'countdown' or 'hidden' to change timeout behavior,
# press ESC key to display menu.
# Uncomment to use basic console
# Uncomment to disable graphical terminal
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
# Uncomment to allow the kernel use the same resolution used by grub
# Uncomment if you want GRUB to pass to the Linux kernel the old parameter
# format "root=/dev/xxx" instead of "root=/dev/disk/by-uuid/xxx"
# Uncomment to disable generation of recovery mode menu entries
# Uncomment and set to the desired menu colors. Used by normal and wallpaper
# modes only. Entries specified as foreground/background.
# Uncomment one of them for the gfx desired, a image background or a gfxtheme
# Uncomment to get a beep at GRUB start
#GRUB_INIT_TUNE="480 440 1"
# Uncomment to make GRUB remember the last selection. This requires
# setting 'GRUB_DEFAULT=saved' above.
# Uncomment to disable submenus in boot menu
# Probing for other operating systems is disabled for security reasons. Read
# documentation on GRUB_DISABLE_OS_PROBER, if still want to enable this
# functionality install os-prober and uncomment to detect and include other
# operating systems.
Also, this is a dual boot system with two SSD’s one of which is running Win10 and One which is running EndevourOS of course. Is it possible that’s affecting my ability to switch kernels when starting up EndevourOS? If you see something amiss in my settings please let me know in any case.
Post your /etc/default/grub as text and add ``` above and below it.
Do not post screenshots of text, nobody wants to waste time reading your screenshots and thus the chances of your problem being solved are significantly decreased.
Also, every time you change that file, make sure to apply the changes with:
sudo grub-mkconfig -o /boot/grub/grub.cfg
If you make a mistake, your system may become unbootable, and then you’ll have to boot a live ISO image, chroot and fix the mistake from there. So, to save yourself the trouble of doing so, don’t make a mistake
Welp that was pretty obvious. Thanks for the help though I got it working. I’m now running the mutli-kernel boot options. Out of curiosity why would someone remove that boot menu? Unless, I guess they’re only using one kernel at all times?
