How to override grub and boot to Ubuntu directly (from UEFI or windows)? - Ask Ubuntu


i changed grub parameters (via grub manager):

grub_hidden_timeout=0.0 grub_timeout=0.0

because wanted grub shows if pressed shift , wanted pc automatically boot windows if didn't press anything.

unfortunately can't display grub pressing shift on start, pc automatically boot windows , can't go ubuntu change setting.

(it's normal boot windows automatically because specified in grub settings)

do know way either access grub or access ubuntu ?

i tried boot override uefi ubuntu still go windows...

thank you.

the first step install windows program access linux partitions within windows described here: (best way access ext partion in windows)

the next step edit /boot/grub/grub.cfg , search timeout changing value 0 5.

save file , reboot.

note after rebooting ubuntu still need change /etc/default/grub otherwise next time run sudo update-grub timeout go zero.
