![]() In case if you wish to change Default OS, you can set from the same file /etc/default/grub.įor the first time, get to the grub menu by hitting Esc at the rite time. (rite time varies based on conditions, generally after the BIOS menu hand overs to grub menu time) When you want to see grub menu, pressing the Esc key at rite time will show you. Because of that, the script /etc/grub.d/30_os-prober contains the following code snippet: adjust_timeout () " != "x" ] then So, what are our options if we want to hide the GRUB menu in a multiboot environment? For once, the grub-common package only wants to make sure that each and every user can switch between the installed operating systems. ![]() In the worst-case scenario you would have to compare and merge the file contents manually. If the package grub-common gets updated in the future, apt would detect the change and prompt you to decide what it should do (as both options - the file modified by you as well as the unmodified file from the distributor - are valid). Output of "apt-file search /etc/grub.d/30_os-prober" Ubuntu 20.04), apt-file shows that /etc/grub.d/30_os-prober belongs to the package grub-common (this is also true for all files located in /etc/grub.d/, which are used by the update-grub command to compile the final GRUB configuration file): Though UnKNOWn's approach does indeed work, the modification of files installed by the base system should be avoided, if possible. ![]() Set timeout=0' | sudo tee /boot/grub/custom.cfg Solution / tl dr echo 'set timeout_style=hidden # Uncomment to disable generation of recovery mode menu entries # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux # you can see them in real GRUB with the command `vbeinfo' # note that you can use only modes which your graphic card supports via VBE # The resolution used on graphical terminal # Uncomment to disable graphical terminal (grub-pc only) # the memory map information from GRUB (GNU Mach, kernel of FreeBSD. # This works with Linux (no patch required) and with any kernel that obtains # Uncomment to enable BadRAM filtering, modify to suit your needs GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` # For full documentation of the options in this file, see: This is my /etc/default/grub file- # If you change this file, run 'update-grub' afterwards to update But it didn't work, menu is still being shown at boot time. I have looked into this thread and added GRUB_HIDDEN_TIMEOUT_QUIET=trueĪnd even changed GRUB_TIMEOUT to 0 and then ran sudo update-grub. I don't want that menu, just want to boot it up right after pressing the power button. When I boot the system, it shows the grub menu for 10 seconds to choose between Ubuntu and Windows. ![]() My purpose is to stop Windows 10 enabling Fast Boot option after every update (I want it off!).I have installed Ubuntu 20.04 alongside Windows. If my idea is sound (I'm open to other suggestions) how do you disable fast boot via CMD/PowerShell?Ĭurrently I have to go to the Control Panel -> Power Options -> Choose what the power buttons do -> (Untick) fast boot. Then also put in that script run powercfg /h off To do this I would have a script that turns off fast boot every time I shut down? (I'm yet to find a way to turn of fast boot via CMD so this is the current issue) If it hasn't solved it I then go back to Windows and run cmd as Admin and enter powercfg /h off and then its usually fixed.īut I figure if it keeps happening it seems a lot of reboots are required and its quite a tiresome process.įirst I need a way to disable fast boot every time I shut down Windows 10? Just incase it gets enabled by some update. So I go to the Control Panel and check if fast boot has been enabled if so I disable it and reboot to Windows 10 (to ensure the setting has been enabled), then shutdown Windows 10 and boot Ubuntu see if the error has gone away. Now I realise every time I start using Windows 10 it normally has updates, these cause fast boot to be enabled. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume read-only with the 'ro' mount option The NTFS partition is in an unsafe state. Metadata kept in Windows cache, refused to mount.įailed to mount '/dev/sda5': Operation not permitted The disk contains an unclean file system (0, 0). Every so often I get an error that looks like this when I try to access my NTFS (Windows) drive from Ubuntu. ![]()
