The Linux boot menu

The boot menu is available in the programs toolstar®testLX and toolstar®shredderLX available. The boot menu has various options and allows the programs to run on almost all devices. Basically, choosing the 64bit – default kernel is the best option. However, if you have trouble starting, the other options may provide a solution. All options are described below.

Navigation within the menu

In the boot menu (GRUB or Syslinux) you can move around with the arrow keys. Use Enter to select an entry to start. However, the extended bootoptions menu item represents something special. This item is not a kernel to start, but rather loads a submenu with further selection options.

Automatic start after 4 seconds

By default, the 64bit – default kernel starts automatically after 4 seconds. You can interrupt the timer using the arrow keys. Once you've done that, none of the kernels will start automatically. You can then select one of the kernels and start it individually using the Enter key.

It happens that connected monitors only start up and show an image after the boot menu. At this point the timer has already expired and the 64bit – default kernel has been started. If you want to prevent this, you can either use a different monitor or continuously press the down arrow key immediately after selecting the USB stick as boot medium. This will interrupt the timer.

Choices in the menu

The following selection options are available to you in the boot menu. The selection options vary depending on which device was started on. For example, certain options are hidden if a pure 32bit CPU was detected.

  • 64-Bit – default
    Kernel: vmlinuz_amd64
    Usage: Default choice, preferred choice for most devices
  • 64-Bit - with Boot-RAM-Test
    Kernel: vmlinuz_amd64
    Usage: The same as 64-Bit - default with RAM test during boot. Can significantly lengthen the boot process if there is a lot of memory.
  • 64-Bit – for very new systems
    Kernel: vmlinuz_amd64_exp
    Usage: Very current kernel with experimental drivers for very new devices
  • 32-Bit – default
    Kernel: vmlinuz_686
    Usage: Default selection for 32bit systems
  • Extended Boot Options
    Usage: Opens a submenu for additional options
  • Within Extended Boot Options: 64-Bit – failsafe mode (start problems)
    Kernel: vmlinuz_amd64
    Use: For startup problems or crashes while booting with other kernels
  • Within Extended Boot Options: Limited mode (start problems)
    Kernel: vmlinuz_686
    Usage: For older systems with limited hardware functions
  • Within Extended Boot Options: 64-Bit – graphics failsafe mode
    Kernel: vmlinuz_amd64
    Usage: For graphics problems and devices with special graphics cards (Matrox, very new Nvidia, etc.)
