Dear GRUBbers,
how can I access the boot menu when GRUB_TIMEOUT=0?
I have searched over the net but none of the proposals I found worked.
For instance, here
<https://unix.stackexchange.com/questions/219061/grub-boot-loader-set-timeout-0-how-to-get-the-boot-menu>
it is suggested to press ESC or SHIFT after post, here
<https://askubuntu.com/questions/262965/grub-timeout-set-to-0-cant-access-grub-menu-anymore>
it is suggested to press SHIFT as well.
I asked because my system did not boot anymore and I had to boot into an
emergency shell.
Thank you and best regards.
P
