Is it possible to completely disable Grub timeout?
Change GRUB_TIMEOUT
value from 10
to -1
, save the file and then run sudo update-grub2
. Reboot and now you have infinite time to choose the OS.
While this works in GRUB, it doesn't work with BURG, and you'll have to change GRUB_TIMEOUT
value to some large number like 120
seconds to wait before booting into any OS and run sudo update-burg
to reflect the changes. Also note that this change must be made to file /etc/default/burg
as BURG doesn't consider options set in /etc/default/grub
Setting timeout to -1 will make GRUB wait infinitely.
By that I mean that you will be required to manually select an entry and hit Enter before launching any OS.
