Boot from hard drive after installation fails

Troubleshooting Installation IssuesTroubleshooting

After the installation completes and the firewall restarts, there are conditions which may prevent the operating system from fully booting. The most common reasons are typically BIOS-related. For example, a BIOS implementation may not boot from a disk using GPT or ZFS, or may require UEFI.

Some of these may be worked around by choosing different options for the partition layout during the installation process. Upgrading the BIOS to the latest version available may also help.

Altering the SATA options in the BIOS has improved booting in some situations as well. If a SATA hard drive is being used, experiment with changing the SATA options in the BIOS for settings such as AHCI, Legacy, or IDE. AHCI is the best mode to use with current versions of AZTCO-FW software.
