version 0.9x), which has, in turn, become GRUB Legacy.Starting with Fedora 16, GRUB 2 is the default bootloader on x86 BIOS systems.A new configuration file is created with: The configuration format has evolved over time, and a new configuration file might be slightly incompatible with the old bootloader.It is therefore a good idea to first run grub2-install whenever you would need to run grub2-mkconfig.Absent Floppy Disk : It has been reported by some users that GRUB 2 may fail to install on a partition's boot sector if the computer floppy controller is activated in BIOS without an actual floppy disk drive being present.A possible workaround is to run (post OS install) from rescue mode: If you wish to password-protect GRUB2's interactive edit mode but you do not want to require users to enter a password to do a plain, simple, ordinary boot, create /etc/grub.d/01_users with the following lines: password_pbkdf2 root grub.pbkdf2.sha512.10000.1B4BD9B60DE889A4C50AA9458C4044CBE129C9607B6231783F7E4E7191D8254C0732F4255178E2677BBE27D03186E44815EEFBAD82737D81C87F5D24313DDDE7.

So, maybe, you need be sure that GRUB_SAVEDEFAULT is not set to true.

Some customizations can be placed in /etc/grub.d/40_custom or /boot/grub2/and will survive running grub2-mkconfig. When you power on your system, your firmware will look for EFI variables that tell it how to boot.

To install or fix GRUB 2 on a UEFI system on Fedora 18 or newer, you need to do four things: UEFI firmware, in general, likes to boot from an EFI System Partition on a disk with a GPT label. The grub2-efi package installs a prebaked grubx64on the EFI System partition, which looks for on the ESP in /EFI/fedora/ whereas the grub2-install command creates a custom grubx64.efi, deletes the original installed one, and looks for in /boot/grub2/. If you're already booted in EFI mode and EFI runtime services are working correctly, you can configure your boot menu with to create new entries with different names.

These include directly setting the default in /boot/grub2/or setting GRUB_DEFAULT to either a number or an entry title in /etc/default/grub. XFS and LVM Note Since recent versions of Fedora and even RHEL/Cent OS have started using xfs and lvm by default, it's worth noting that these steps outlined here may need to be preceded with the necessary step to load the XFS and/or LVM module(s). If this partition contains /boot, the output will show the full name of vmlinuz and initramfs. Armed with the location and full name of vmlinuz and initramfs you can now boot your system. Declare your root partition: It's also possible to boot into a configfile that's located on another partition.

If the user is faced with such a scenario, as is often the case with multi-boot systems containing Ubuntu and Fedora, the following steps in the grub rescue shell might become useful to know: Where, hd0,msdos1 is the pertinent boot partition, which holds the file.
