Gigastrand OS Boot Issues


There are a few BIOS settings that could affect the ability of a PC to boot the Gigastrand OS. Below are a few of the more common solutions to these issues.

Legacy Boot: This is a setting in most BIOS that, if not turned on, will not allow the Gigastrand OS DVD or USB drive to startup. This is required to boot Gigastrand OS. Gigastrand PCs enable this by default. Accessing the BIOS settings is always accessed with a keypress before the computer boots the operating system.Consult your PCs manual to find out how to access your BIOS settings. Common keys to access the BIOS settings are: Del, F2, F10, or F12.

Boot Order: If the computer is set to startup to the hard drive first, you might not be able to run the installation media. You could change the boot order in the BIOS however, most PCs also have a boot menu that will allow you to select the drive you want to use. Make sure your media is loaded or plugged in before you try to access this menu or your drive might not be listed. This menu is also accessed by a keypress before the computer boots. Common keys are: F12, F9, or F2

Advanced Host Controller Interface (AHCI) mode: This mode is a property of the SATA controller that allows advanced features like hot-swapping drives and other advanced features. How you know you should check for this solution is after install, you reboot and get a GRUB error: 

error: file '/grub/i386-pc/normal.mod' not found.
grub rescue>

This is a strong indication that you need to change the SATA controller settings in the BIOS from AHCI to IDE or ATA. Gigastrand OS does support AHCI, but not on all hardware. When you reboot, the hard drive should boot fine. If not, reinstall the Gigastrand OS and it should start fine.
