Good Morning everyone, how can i change the grub2 bootloader timeout? (direct command in terminal to change it to 0 sec) Also what are the other tips to make this boot faster?
Systems with LVM partition enabled experience no timeout changes when setting GRUB_TIMEOUT. The reason is that grub lacks write support for LVM. Further info you can find at here
Adding a timeout for recordFail at /etc/default/grub in Grub should solve your issue:
sudo sh -c 'echo GRUB_RECORDFAIL_TIMEOUT=0 >> /etc/default/grub' sudo update-grub
It will add GRUB_RECORDFAIL_TIMEOUT=0 to /etc/default/grub file
