Red Hat's Hans de Goede is working on making he GRUB menu hidden by default on Fedora in order to improve the boot experience - just as Ubuntu and other Linux distributions have been doing for years. Surprisingly this has spun into a lot of discussion and debate over the matter. Have a look at the answers to this question for instructions on using both methods.A feature proposal for Fedora 29 would hide the GRUB boot menu by default on installations where Fedora is the only installed operating system. So using the command gksu gedit /etc/default/grub and uncommenting / removing the #hash from what appears as line 364 in the boot info script as #GRUB_GFXMODE=640x480 should work.Īfter saving the changes you will need to run sudo update-grub

This can be resolved by using the 'out-of-range' option in the advanced section of boot repair or editing grub manually.Īccording to lines 346 to 348 of the boot info script grub should be displayed.

If Windows loads then grub is working fine, but not being displayed. You can test to see if this is the case by tapping the 'down arrow' key for at least 15 seconds after the bios screen and then pressing 'enter'. The monitor displayed 'frequency out of range'. I have encountered a similar problem previously, a blank screen after bios until the Ubuntu login screen appeared, using an older LCD monitor. Again, do not choose partitions but whole drives. To get grub2 to remember where to reinstall on updates: sudo dpkg-reconfigure grub-pcįrom there press enter through the first pages, use spacebar to choose/unchoose the drive, and enter to accept. To see what drive grub2 uses look for the line - grub-pc/install_devices in: sudo debconf-show grub-pc sudo grub-probe -t device /boot/grub If that returns any errors run: sudo grub-install -recheck /dev/sdb sudo update-grub Then, if for example it's '/dev/sdb', just run: sudo grub-install /dev/sdb To reinstall Grub from an active (not liveCD/DVD/USB only) system - first you need to find the Ubuntu drive (example is sdb, but make sure to use your drive and not a partition).

This UbuntuForums thread discusses it a bit further, and oldfred's solution for how to fix it there worked for me as well: Note that (at least on some old Ubuntu installs), if installed via USB, it may write the GRUB to the USB instead of the hard drive you've installed to. *choosing which cd/dvd is important because grub versions are different.Best is to use the same version live cd/dvd.use your ubuntu 12.04 live cd. Restart, you will have boot menu showing both OS. Take only /dev/sda or /dev/sdb.įinal step is to open terminal and type this command: sudo grub-install -root-directory=/media/ Įxample : sudo grub-install -root-directory=/media/disk1 /dev/sda It shows all the partitions with its device name, UUID and etc. If you have more than one HD, You can find that by typing this command in terminal (applications->accessories ->terminal )“sudo blkid”. Find the mount point of root partition.It will be in /media (example: /media/disk1 or /media/234efsdfgg5dg435gh) and the device name, default name is /dev/sda. After you mounted the partition,which has folders like boot, home, root, usr, bin, tmp.the root partition (old).now it’s like any other normal partition. Mount the partition in which UBUNTU was installed before i.e.Boot your system with UBUNTU live dvd/cd*.Reinstalling GRUB (GRand Unified Bootloader) : so you need to reinstall GRUB.Provided you have not formatted Ubuntu filesystem, while installing Windows XP.

I assume you tried to install windows XP after Ubuntu installation.Windows loader will replace GRUB loader. Or you can instead uncomment in /etc/default/grub GRUB_TERMINAL_OUTPUT=console Or to make the solution permanent, add the following line at top of /etc/grub.d/00_header echo 'videoinfo'

To keep grub busy in console and give enough time to load video modules, add the following line at top of /boot/grub/grub.cfg # To resolve race condition when loading video drivers This will automatically be run each time a new kernel is installed by sudo apt full-upgrade sudo update-grubĮdit-Apr-25-2022: In Ubuntu 20.04.1, auto loading of grub modules causes race condition on slow PCs. If you have modified this file then you need to run update-grub for it to take effect. This will cause the grub menu to be displayed for the number of seconds in GRUB_TIMEOUT before selecting the default and booting that. You can also modify /etc/default/grub comment out the line by adding a # to the start like: # GRUB_HIDDEN_TIMEOUT=0 Hold down the shift key during the boot process this will give you the menu on a one off basis.
