YaST (Yet another Setup Tool) is a Linux operating system setup and configuration tool.
YaST is featured in the openSUSE Linux distribution, as well as in SUSE’s derived commercial distributions. It is also part of the defunct United Linux.
YaST features tools that can configure many aspects of the system including GRUB.
The Boot Code Options tab includes the following additional options:
- Set Active Flag in Partition Table for Boot Partition – Activates the partition that contains the /boot directory. For POWER systems it activates the PReP partition. Use this option on systems with old BIOS and/or legacy operating systems because they may fail to boot from a non-active partition. It is safe to leave this option active.
- Write Generic Boot Code to MBR – If MBR contains a custom ‘non-GRUB’ code, this option replaces it with a generic, operating system independent code. If you deactivate this option, the system may become unbootable.
- Enable Trusted Boot Support – Starts TrustedGRUB2, which supports trusted computing functionality (Trusted Platform Module (TPM))
