Troubleshooting Common Issues

If you encounter problems while using netboot.xyz, try these solutions:

1. PXE boot not working:

   • Verify that PXE boot is enabled in your BIOS/UEFI settings
   • Check DHCP and TFTP server configurations

2. Slow boot times:

   • Consider caching frequently used OS images locally
   • Use a faster internet connection or local mirror

3. OS not appearing in the menu:

   • Ensure you have the latest netboot.xyz version
   • Check if the OS is supported by netboot.xyz

4. Boot process hangs:

   • Verify network stability and firewall settings
   • Try a different OS or utility to isolate the issue

Advanced Netboot.xyz Features

Once you're comfortable with basic network booting, explore these advanced features:

1. Custom scripts: Create your own boot scripts for specialized tasks.

2. Local hosting: Host netboot.xyz locally for faster access and customization.

3. iPXE scripting: Use iPXE scripting to automate complex boot processes.

4. Integration with other tools: Combine netboot.xyz with provisioning tools like Ansible or Puppet.

Example: Creating a Custom Boot Menu

Here's a simple example of how to create a custom boot menu using iPXE scripting:

#!ipxe

:start
menu Custom Boot Menu
item ubuntu20 Ubuntu 20.04 LTS
item fedora33 Fedora 33
item exit    Exit to main menu

choose --timeout 30000 --default ubuntu20 option && goto ${option}

:ubuntu20
chain --autofree https://boot.netboot.xyz/ubuntu/focal/ubuntu.ipxe

:fedora33
chain --autofree https://boot.netboot.xyz/fedora/33/fedora.ipxe

:exit
exit

goto start

Save this script as custom_menu.ipxe and add it to your TFTP server. You can then boot into this custom menu by chainloading it from the main netboot.xyz menu.
