To boot from a CD, DVD or USB device, make sure that the device has the boot sequence priority over the hard drive.
BIOS (Basic Input Output Subsystem) is a programmable chip that controls how information being passed to various devices in the computer system. A typical method to access the BIOS settings screen is to press ESC, F1, F2, F8, F10 or Del during the boot sequence.
BIOS settings allow you to run a boot sequence from a removable disk, a hard drive, a CD-ROM drive or an external device. You can configure the order that your computer searches these physical devices for the boot sequence. The first device in the order list has the first boot priority. For example, to boot from a CD-ROM drive instead of a hard drive, place the CD-ROM drive ahead of it in the priority list.
While you are in the BIOS Setup Utility, you will not be able to use your mouse. Use the keyboard arrow keys to move around the screen.
Before you set boot priority for a USB device, plug the device into a USB port.
To specify the boot sequence:
The computer will restart with the changed settings.
Some computer manufacturers allow you to select the device that contains the boot sequence from a special device selection menu. The example below uses a Dell system board.
To set boot priority using a device selection menu:
Note: Using an incorrect BIOS setting can cause a system malfunction. Please follow the BIOS guide provided with your computer motherboard. If you read these instructions and you are not sure how to change a setting, it is better to leave it as the default setting.
Some modern computers use new advanced UEFI x64 or x86 secure boot approach instead of the standard BIOS boot.
Active@ LiveCD fully supports UEFI secure boot on both 32-bit & 64-bit systems, and will boot up the machine automatically.
In case any malfunctions with UEFI secure boot (if your machine does not boot after you set up boot priority as it is described above), you should check that BIOS boot is enabled (Legacy mode), or UEFI is disabled.
Here is how you can check your BIOS settings.
At the moment of turning your computer on, you will see an option to enter SETUP. Depending on the manufacturer of your system, you can press the DEL key, the F2 key or another key that is listed on screen to access the system BIOS. If you are not sure, consult the User Guide that came with your computer or call the manufacturer's technical support for assistance.
Once in your system BIOS, look under the Boot menu to find an option that says "UEFI/BIOS Boot Mode" or "UEFI Boot". In the case of "UEFI/BIOS Boot Mode" switch the mode from "UEFI" to "Legacy" mode.
If you see "UEFI Boot", switch the option from "Enabled" to "Disabled". Be sure to save your BIOS changes and exit to reboot your computer. You should now be able to boot up from Active@ LiveCD.
