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¶

BIOS/UEFI¶

Reboot to BIOS¶

# Reboot directly to BIOS/UEFI setup
ujust bios

System will reboot and enter BIOS setup automatically.

View BIOS Info¶

# Display BIOS information
ujust bios-info

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

GRUB Configuration¶

Regenerate GRUB¶

# Regenerate GRUB configuration
ujust regenerate-grub

Useful for: - Dual-boot setup changes - New kernel installations - Boot parameter changes

GRUB Menu Visibility¶

# Interactive: choose hide/unhide/show
ujust config-grub

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

Secure Boot¶

Enroll Secure Boot Key¶

# 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¶

# 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¶

# Regenerate GRUB to detect Windows
ujust regenerate-grub

# Show GRUB menu on boot
ujust config-grub show

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

Secure Boot with NVIDIA¶

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

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

Hide Boot Menu¶

# For single-boot systems
ujust config-grub hide

Troubleshooting¶

GRUB Not Showing Windows¶

Fix:

# 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:

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:

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