For instance, to support hibernation, users will need to add GRUB_CMDLINE_LINUX="resume=/dev/sdXY" with /dev/sdXY being the swap partition. Parameters to be passed on the kernel command line for all Linux menu entries. Set to 0 to boot immediately or -1 to wait indefinitely. May be a numeric index, a menu title, or "saved".ĭelay (in seconds) before booting default menu entry. The following variables in /etc/default/grub are the most common ones to set to control how GRUB will function:ĭefines the default menu entry selected on boot. Make sure the output is satisfactory before restarting the system. In this case GRUB will offer no boot selections when upon system restart which may be a tricky, time consuming situation to resolve. If grub-mkconfig does not report any found entries then no entries were found. This utility will use the scripts in /etc/grub.d/ and the settings in /etc/default/grub. Instead it can generate its configuration file ( /boot/grub/grub.cfg) using the grub-mkconfig command. GRUB does not require the administrator to manually maintain a boot option configuration (as is the case with boot loaders such as GRUB Legacy and LILO). See GRUB2 configuration variables or the official reference for supported variables. It is mainly used to assign variables used by the scripts in /etc/grub.d to generate a working configuration file. In most cases this is the only file that should be modified directly. This file provides a place to add additional entries or commands and does not require regeneration of the main grub.cfg file. The /etc/grub.d/41_custom script will reference this file to be read in at boot time if it exists. For instance, to add menu items that couldn't be automatically generated. It may be necessary to disable or add scripts. Ideally they should be POSIX-compatible scripts, and the output script must be compatible with the GRUB2 interpreter.
These scripts use the current system shell and therefore can use any supported syntax. Be aware that modifications to this file won't persist to the next time grub-mkconfig is run.Įach script under /etc/grub.d/* that has its execute bit set is evaluated in sequence, and the stdout is concatenated to form the final /boot/grub/grub.cfg (or whatever file is given to the grub-mkconfig -o option).
GRUB2 WINDOWS 10 64 MANUAL
See the scripting reference in the GRUB manual for supported features. This file is evaluated by GRUB2's built-in script interpreter and doesn't necessarily support all POSIX commands or syntax. Run this script to generate /boot/grub/grub.cfg after configuring the files described below. Installed as part of the sys-boot/grub:2 package. It uses the scripts under /etc/grub.d/* together with the /etc/default/grub configuration file to generate the final /boot/grub/grub.cfg - the only configuration file used by GRUB2 itself. The grub-mkconfig script is used to generate a grub configuration. First we cover the configuration of the boot loader itself.
GRUB2 WINDOWS 10 64 SOFTWARE
The installation of GRUB software is specific to the type of system, and is covered in Installing the boot loader. Installation of GRUB software as the secondary boot loader of the system.There are two important aspects to the configuration of GRUB:
GRUB2 WINDOWS 10 64 INSTALL
To install the boot loader to the system itself (so that it is used when booting the system), additional steps need to be taken, which are covered in the Configuration section. These only install the boot loader software on the operating system. The GRUB (and optionally sys-boot/os-prober) installations do not automatically enable the boot loader's operation. Root # emerge -ask -newuse sys-boot/os-prober The amd64 architecture includes a profile default which works for most systems. To control which platforms GRUB will install for, set the GRUB_PLATFORMS variable in nf. Legacy was removed from the Gentoo ebuild repository.
GRUB2 WINDOWS 10 64 UPGRADE
It is recommended all systems should upgrade to GRUB2, since it supports all the same features sets as Legacy. EFI fileĭue to the way GRUB Legacy (grub-0.97) and GRUB2 were slotted in Gentoo, both versions of GRUB may be installed on the same system at the same time however, only one version at a time may be installed in the Master Boot Record (MBR) of a hard drive. 5.2 Motherboard firmware not finding the.3.4 Open Firmware (IEEE 1275) on PowerPC.3.3.2 Alternative: using the default UEFI firmware location.2.3 Enabling or disabling configuration scripts.
