CREATE BOOTABLE UEFI Key ON WINDOWS
=====================================
Note: all data will be lost on the USB Key that you use to create the Lenovo bootable UEFI.

After you download the file, follow these steps:
1. unzip the package file just downloaded.
2. Plug the USB key into your computer
3. Log in to Windows, go to the Windows Start menu and launch the command window with Administrator privilege.
4. At the prompt, select Yes.
5. Navigate to the folder where UefiBootableGenerator.exe is located and run this command:
UefiBootableGenerator.exe --list
7. The window will display the drive letter of the USB key 
8. Now create the USB key by entering this command:   
BootableGenerator.exe --create -l  -u  -f 

where
*<-1>  is the new name of the USB key (limit of 11 characters)
*<-u>  is the drive letter assigned to the USB key 
*<-f>  is the name of the image
 
For example:
If the USB key has been assigned as Drive "I" by Windows, the image you downloaded is "UEFI_Bootable_v02.01.06.zip", and you name the USB key as "boot", the command would read as follows:

UefiBootableGenerator.exe --create -l boot -u I -f "UEFI_Bootable_v02.01.06.zip"

9. At the prompt, type "y" and press the "Enter" key to format the USB Key and start to create the UEFI bootable key.

ENABLING UEFI AT STARTUP
============================================
Follow below steps to check if your system is UEFI enabled and how to enable UEFI Boot at startup
1. Reboot your machine, and when the splash screen appears (the one with the Lenovo Logo), press described button to interrupt normal startup.  This is typically the “Enter” key.
After interrupting normal startup, the “Startup Interrupt Menu” will be displayed in screen. Now press the key to access “BIOS  Setup Utility”, which in this case is “F1”.
2. The BIOS setup utility is now displayed.  If  the BIOS Version and BIOS Date start with UEFI, the machine is UEFI enabled. 
3. To enable UEFI, use the left arrow (<-) or Right arrow (->) key to highlight the "Startup" menu
4. Use the Down arrow key to highlight the UEFI/Legacy Boot item. 
5. Using the Arrow and Enter keys change this setting to "Both"
6. Now highlight the UEFI/KLegacy Boot Priority item, and using the arrow and Enter keys, change this setting to "UEFI First". 
7. To save, press the F10 key to save and exit the BIOS utility.
