ProblemĪfter a fresh install of ubuntu on the blank SSD (windows was on another SSD, both SSDs are setup with GBT which requires UEFI), the system directly boot into ubuntu without showing grub menu.Īlthough I can still select which system to boot in BIOS menu, I really prefer a grub menu rather than going into BIOS every time I want to switch. Hours after the release of ubuntu 20.04 beta, I decided to give it a try with a newly purchased WD blue SSD to replace the 5-year-old HDD. I have been expecting the arrival of the new LTS ubuntu. The dual boot works well for two years with the grub menu showing up every time the computer spins up. I have a ubuntu 18.04 LTS + windows 10 dual boot system on my laptop. If your grub menu does not show up even after you set GRUB_TIMEOUT_STYLE=menu and GRUB_TIMEOUT=10 in /etc/default/grub and updated the grub, try setting (uncommenting) GRUB_TERMINAL=console as well and re sudo update-grub. So if nothing else seems to work, switching the monitor cables might do the trick.įunny to see Windows files on their proper places and not have access to the windowsOS.Photo by Michael Dziedzic on Unsplash TL DR Finally turned on the secondary monitor (it’s usually off) and there was the grub-menu ! I believe i just need to switch the monitor cables around to get it on the main monitor? Believing grub goes to motherboard so sends the info to the monitor attached to it. Setting the grub config “hidden” to “visible” and sudo udate-grub at the prompt didn’t help. Upon restart, didn’t get the grub menu to show up. Set up a harddisk partition in windows for Linux and let the Linux installation program do its thing (install keeping windows intact) Rather smooth also, checked the windows was still on it’s partition. Now, reboot Linux Mint, and the GRUB boot menu should appear automatically at startup.Īfter realizing some components in the system need 32-bit info, got the linux mint 19.3 for an old machine. Now, go back to the terminal and type: sudo update-grub Now scroll down and remove the hash mark in front of this line: GRUB_GFXMODE=640x480 This timeout configuration setting causes the GRUB menu to automatically choose the selected item after ten seconds. If you like, you can also change the timeout time in seconds. In earlier versions of Linux Mint, the line might look more like this: #GRUB_HIDDEN_TIMEOUT=0 By doing this you are basically disabling the “hidden” configuration of the GRUB boot menu, thus allowing it to appear when Linux Mint starts up. This hash mark “comments out” this line in the configuration file so that it will be ignored by Linux at boot time. Place a hash mark in front of it so that it appears like this: #GRUB_TIMEOUT_STYLE=hidden Scroll down to the following line: GRUB_TIMEOUT_STYLE=hidden If you’re using a different version of Linux Mint, your GRUB configuration file may look different. The above GRUB configuration file appears in Linux Mint 20. Scroll down to to the lines that deal with GRUB configuration. But since GEDIT doesn’t come pre-installed with Linux Mint, we must install it first. We are going to use GEDIT to edit the GRUB configuration file. Show Boot Menu by Editing GRUB Config File The GRUB boot menu will display with available boot options. The following boot menu appears in Linux Mint 20. When you start Linux Mint, simply press and hold down the Shift key to display the GRUB boot menu at startup. You can show the boot menu at startup using the following methods. The boot menu, known as GRUB, is usually disabled by default in Linux Mint.
