Booting the Program

Should issues arise while booting the program from a USB stick or a CD/DVD (for example if the screen turns black or if the startup screen freezes), appropriate solutions are described below.

BIOS USB Boot

If the boot media (USB stick or CD/DVD drive) is not listed in the BBS menu, activate USB boot support in the BIOS setup. Press  F2 ,  Del  or  F10  (depending on the BIOS) to enter BIOS setup. The setting can be found under different names and menu items, depending on the BIOS version. In most cases, it can be located under terms such as  USB , Boot and Legacy. In the BIOS setup you can also opt to boot from USB permanently, usually by using the menu item Boot.

UEFI Boot and SecureBoot

Later PCs often have a UEFI BIOS. The program supports booting with UEFI. Some PCs also offer the SecureBoot function, which is also supported. Should you encounter problems with SecureBoot, deactivate this function prior to booting the program. You may reactivate SecureBoot again afterwards. If issues still occur while booting with UEFI, recreate the boot media with the Boot Setup while the UEFI Boot Support option is deactivated, then repeat the boot process.

Note: In newer versions of Windows, especially starting at Windows 8, UEFI BIOS can often only be accessed through the operating system. The easiest way to achieve this is via the login screen. Click on the On/Off icon to open the menu upon restart. Keep the Shift button pressed while clicking on Restart. This will take you to a blue screen titled  Choose an option . Here you can select  Troubleshoot . On the next screen, select Advanced options, then select  UEFI Firmware Settings  on the final screen.

Extended Boot Options

The boot settings of the self-booting variants are optimized for fast booting. If there are any problems with the booting, change the settings on the boot screen and press  M  for More Options. This will display the Extended Boot Options.

You may choose whether you wish to start the Symobi or Linux variant here.

• Start Symobi: Start the native system.
• Start Symobi/L: Start the Linux-based system.

• Normal: Start the system with the most efficient configuration.
• Compatible: Conservative configurations with minimal limitations.
• Emergency: Minimal configuration to save a system log.
• Safe: Reduced configuration, limited device support.

Graphics Mode

A certain graphics mode can be selected, should issues occur.

• Auto: Automatically determine a graphics mode.
• Native: Use UEFI graphics mode (only with UEFI BIOS).
• VESA: Use VESA mode via BIOS.
• VGA BIOS: Use VGA mode via BIOS.
• VGA: Initialize VGA mode natively.

System Log

Options to save a system log.

• Normal: Standard setting for gathering runtime information in the system log.

Startup Options

You may activate or deactivate the options individually and boot with one of the start modi afterwards.

• USB: Deactivate in order to prevent disturbances from devices that are connected to normal USB ports (connect input devices to USB 3 or PS/2!).
• Advanced HID: Advanced support for input devices. Deactivate if problems with the keyboard or mouse occur.
• SATA port multiplier (extended detection): Activate if disks that are connected with port multipliers are not recognized.

Select the desired start modi and options, and boot with the desired start selection afterwards (keys ↑ ,  ↓  and  Enter ).
