Grub
Operating system bootloader is a system software intended
for loading the operating system during computer startup. The software used
for this purpose is GRUB.
Boot menu, prepared during installation of the bootloader, will have
entries for all the operating systems encountered on the computer.
You need to choose the destination for installation of the bootloader:
- EFI — bootloader will be installed on a special partition
called EFI (in EFI installation mode). There are a few hardware-dependent
options. If one of the options doesn't work for you, try other options.
- recommended — bootloader installation process
results in making a record to NVRAM. Without this record most of the computers
will not be able to load newly installed operating system.
- clear NVRAM before — before adding a new record
to NVRAM, its contents are saved to /root/.install-log. Then all
the boot entries get cleared resulting in restoration of a completely
filled NVRAM to ensure loading of newly installed operating system.
- disable write to NVRAM — choose this option only
in case if the installer could not create a record in NVRAM or when
it is already known that adding the record to NVRAM can disable the computer
(most probably the record in NVRAM would have to be created after
installation of the operating system by means of BIOS Setup).
- for removable device — choose this option if the system
is installed on the removable storage drives. This option can also
be used instead of the disable write to NVRAM
provided that it would be the only OS on that drive and adding an
NVRAM entry will not be necessary.
- RAID — bootloader will be installed on the partition
of created RAID array.
- Hard drive — bootloader will be installed
to MBR (Master Boot Record) of the hard drive. In this case the main boot
loader will be installed for all the encountered operating systems.
Recommended for most cases.
- Linux partition — bootloader will be installed
on a Linux partition. Recommended when using another software
as the main bootloader.
- Skip bootloader install — refuse installation
of the bootloader. Bootloader can be installed and configured later.
Attention! Choosing this option requires advanced technical
skills for loading the installed operating system and not recommended
for newbies.
* By default, the bootloader password is added for the boot user.
