2. Booting Safe Setup
To configure a Boot Safe System
Check if you dispose of a Fallback Kernel to startup:ls | grep initrd
If more than one output on entry then you can go to the next Step!
If not then duplicate an existing Initrd and Kernel Image like:sudo cp vmlinux[VERSIONID] vmlinux-fallback
sudo cp initrd[VERSIONID] initrd-fallback
Just replace [VERSIONID] with a current identifier.

With this in case you’ll be sure to boot your System choosing this Kernel on GRUB Splash advanced options.
