Dual boot setup- no GRUB on boot

rated 0 times [ 0] [ 0] / answers: 1 / hits: 1121 / 2 Years ago, mon, january 24, 2022, 11:20:56

On a dual boot Ubuntu 18.04LTS -Windows 10 setup.

By default I launch into Ubuntu

I see a black screen on boot for about 10 seconds then my desktop.

I last reconfigured my setup over a year ago but can't recall what I did to hide the GRUB on boot.
I was able to see the GRUB menu on boot at one time.

My goal is simply to log into BIOS to switch my startup to my Windows partition.

Any help appreciated!

You can change some grub options by editing the /etc/default/grub file. One thing to try could be to change the GRUB_TIMEOUT value there to some larger value, like 30 or so, then it should wait for 30 seconds hopefully giving your screen enough time to show the menu.

After editing the /etc/default/grub file, run the update-grub command:

update-grub

and then reboot.
