Boot - Bazzite Boot Configuration

Overview

The boot skill covers BIOS/UEFI access, GRUB configuration, secure boot key management, and Windows dual-boot setup.

Quick Reference

Command Description
ujust bios Reboot to BIOS/UEFI setup
ujust bios-info Display BIOS information
ujust regenerate-grub Regenerate GRUB config
ujust configure-grub Configure GRUB menu visibility
ujust enroll-secure-boot-key Enroll NVIDIA/KMOD secure boot key
ujust setup-boot-windows-steam Add Windows to Steam boot options

BIOS/UEFI

Reboot to BIOS

bash
# Reboot directly to BIOS/UEFI setup
ujust bios

System will reboot and enter BIOS setup automatically.

View BIOS Info

bash
# Display BIOS information
ujust bios-info

Uses dmidecode to show BIOS vendor, version, and date.

GRUB Configuration

Regenerate GRUB

bash
# Regenerate GRUB configuration
ujust regenerate-grub

Useful for:

  • Dual-boot setup changes
  • New kernel installations
  • Boot parameter changes

GRUB Menu Visibility

bash
# Interactive: choose hide/unhide/show
ujust configure-grub

# Non-interactive options
ujust configure-grub hide     # Hide GRUB menu (instant boot)
ujust configure-grub unhide   # Show GRUB menu briefly
ujust configure-grub show     # Always show GRUB menu

Secure Boot

Enroll Secure Boot Key

bash
# Enroll NVIDIA driver and KMOD signing key
ujust enroll-secure-boot-key

Required for:

  • NVIDIA proprietary drivers with Secure Boot enabled
  • Custom kernel modules
  • Third-party drivers

Process:

  1. Generates MOK (Machine Owner Key)
  2. Prompts for password
  3. Reboots to MOK Manager
  4. Enter password to enroll key

Windows Dual-Boot

Add Windows to Steam

bash
# Add Windows boot option to Steam non-Steam games
ujust setup-boot-windows-steam

Allows booting to Windows directly from Steam's game library.

Requirements:

  • Windows installed on separate partition/drive
  • GRUB detecting Windows entry
  • Steam installed

Common Workflows

Dual-Boot Setup

bash
# Regenerate GRUB to detect Windows
ujust regenerate-grub

# Show GRUB menu on boot
ujust configure-grub show

# Add Windows to Steam
ujust setup-boot-windows-steam

Secure Boot with NVIDIA

bash
# Enroll the signing key
ujust enroll-secure-boot-key

# Follow prompts, set password
# Reboot and enroll in MOK Manager

Hide Boot Menu

bash
# For single-boot systems
ujust configure-grub hide

Troubleshooting

GRUB Not Showing Windows

Fix:

bash
# Regenerate GRUB config
ujust regenerate-grub

# Check os-prober
sudo os-prober

Secure Boot Key Enrollment Fails

Check:

  • Secure Boot enabled in BIOS
  • No pending updates
  • Reboot completely (not just suspend)

Retry:

bash
ujust enroll-secure-boot-key

Can't Boot After GRUB Change

From GRUB menu:

  1. Press e to edit entry
  2. Modify boot parameters if needed
  3. Press F10 to boot

Recover:

bash
# Boot from live USB
# Mount system partition
# Regenerate GRUB
