I'm having concerns with rebooting my laptop. It's a Toshiba Satellite C875-S7344 with Windows 8. I purchased a CD to help reboot but it mentioned to disable the Secure Boot. Not sure if I am using the wrong sequence but, it doesn't seem to be working. At start-up I keep getting a "Checking Media - Fail" message. Then it says "Checking Media" again, then goes to "No Bootable device - Restart System". Not sure if I have a software or hardware problem. Any help/direction would be appreciated.
 
To disable "Secure Boot"...

1. Make sure disabling it is actually necessary. If installing older software, or untrusted software, then you may need to disable it. However, if you are installing newer versions of Windows, you should not need to disable it.

2. Open BIOS.

3. Locate the Secure Boot setting, and if possible, set it to "Disabled". This can be found in either the "Security" tab, the "Boot" tab, or the "Authentication" tab.

4. Save your changes and exit.

5. The computer should reboot.

6. Now you can install the graphics card, hardware, or operating system that’s not compatible with Secure Boot.

7. If this isn't working for you, in some cases, you may need to change other settings in the firmware, such as enabling a Compatibility Support Module (CSM) to support legacy BIOS operating systems. To use a CSM, you may also need to reformat the hard drive using the Master Boot Record (MBR) format, and then reinstall Windows.

NOTE: If you’re using Windows 8.1, you may see a watermark on the desktop alerting you that Secure Boot is not configured correctly. Get this update to remove the Secure Boot desktop watermark.


To re-enable "Secure Boot"...

1. Uninstall any hardware, OS, etc., that isn't compatible with Secure Boot.

2. Open BIOS.

3. Locate the Secure Boot setting, and if possible, set it to "Enabled". This can be found in either the "Security" tab, the "Boot" tab, or the "Authentication" tab.

4. On computer computers you will need to select "Custom", and then load the Secure Boot keys that are built into the computer.

5. If the computer does not allow you to enable "Secure Boot", try resetting the BIOS back to the factory settings.

6. Save your changes and exit.

7. The computer should reboot.

8. If the computer does not reboot after enabling "Secure Boot", go back into the BIOS menus, disable "Secure Boot", and try rebooting the computer again.

9. In some cases, you may need to refresh or reset your computer to its "original state" before you can turn on "Secure Boot".
