Langmeier Backup

Under Windows 8, 8.1 and Windows 10 or 11, the BIOS configuration for the boot process must be temporarily changed for security reasons on computers that use Bios 8 and are configured for Secure Boot in order to start bootable data carriers such as the Langmeier Backup rescue medium.

Switching from UEFI mode to legacy mode

Why does the UEFI mode have to be deactivated?

In UEFI mode it is not possible to boot from USB stick, CD, DVD, NIC, etc. on Windows 8/8.1 /10 systems - therefore we temporarily switch to legacy mode. Proceed as follows:

For Lenovo and Acer computers

1. restart the computer/laptop and hold down the F2 button until you see the BIOS page. Use the arrows on the keyboard to navigate to the"Boot" option.

2. with Boot Mode highlighted, press Enter and use the down arrow to go to Legacy BIOS - press Enter

3. now press the key combination Fn+F10 and select"Yes". Confirm this with the Enter button to save the changes.

Now you can boot with the Langmeier Backup - rescue medium and perform a restore. You can also use this process to undo the changes.

Deactivate Secure Boot

In some cases, the "Secure Boot" must be deactivated so that you can boot from boot media. In the BIOS under the same tab"Boot" you will find the entry"Seucre Boot" - this is set to "Enabled" by default. To deactivate"Secure Boot", select the option with"Enter" and set it to"Disabled". Press F10 to save the changes and then restart the computer.

For Dell computers

1. press and hold the F2 or F12 button as soon as you start the Dell laptop - the BIOS mode will appear.

2. go to the "Boot" tab via the right arrow - there is the option"Secure Boot" - change this to"Disabled".

3. check that the option"Load Legacy Option Rom" is activated and change this option to"Enabled" if necessary.

4. set the"Legacy" mode on the"Boot List Option" tab.

You can close the BIOS mode via"Exit" and save the changes.

Now you can boot with the Langmeier Backup - Rescue medium and perform a restore. You can also use this process to undo the changes.

For HP computers

1. . Press and hold the F10 button (on some HP models also F2 or F8) as soon as you start the HP computer - the BIOS mode will appear.

2. use the right arrow to go to the"Security" tab - there is the option"Secure Boot Configuration (or Secure Boot Options)".

3. press Enter to open a small blue window, change the"Secure Boot" option to"Disable" and"Legacy Support" to"Enable".

If there is no"Security" tab, search for the"System Configuration" tab and set the"Secure Boot" option to"Disabled".

Now press F10 to save the changes. The HP will now restart and boot successfully from the Langmeier Backup rescue media. The changes can also be undone in these windows.
