Configuring the Boot Loader

You can configure the boot loader to use specific boot options that can control installation at the point of boot. For example, you can provide the network location of an install ISO, or the location of a Kickstart file used to automate installation.

Boot options are specified at the boot command line of the boot menu.

Boot the system.
Access the boot options in the boot menu.

When the boot menu is displayed, select any installation option, then press either E on UEFI-based systems or Tab on BIOS-based systems.

The boot options line is displayed with some default options already defined.
Add any required options at the end of the line.

Separate boot options with a space. Options that require parameters must be in the option=parameter format.

For a list of common boot options, see Installation Boot Options.
Save the changes.

Save the changes by pressing either Ctrl+X on UEFI-based systems or Return on BIOS-based systems.

To discard changes and return to the boot menu, press Esc.

This example shows settings for the inst.repo and inst.ks options:

inst.repo=nfs:nfs.example.com:/ISOs/OL8/full_image.iso \
inst.ks=nfs:nfs.example.com:/kickstart/OL8/server-ks.cfg ip=dhcp

With these directives, the installation program is instructed to do the following:

Use the full installation image stored on an NFS share directory.
Start the installation automatically by using a file also stored on an NFS share directory.
