Re: Yoga 2 11 USB boot

On my Yoga 2 11, an EFI boot option magically appeared on the Boot Menu (from the Novo Button Menu) when I redid the bootable USB for my new operating system using the most recent version (currently ver.1.5.12) of the free program Rufus.

 

Partition scheme and target system:  GPT partition scheme for UEFI computer

File system:  FAT32 (default)

16 kilobytes (Default)

Check:  Create a bootable disk using:  ISO Image, selecting from the icon to the immediate right the .iso image file that you have for the new operating system that would otherwise be used to create a bootable DVD.

 

I did not need to make any changes to the BIOS under BIOS setup.  (Those default options include Secure Boot <Enabled>; Platform Mode = User Mode; Secure Boot Mode = Standard; Fast Boot = Enabled; USB Boot = Enabled.)  I had initially monkeyed around with these options to no avail.  To return to the default options, I selected, "Restore Factory Keys" on the Security screen and Load Default Settings on the Exit menu, then Save and Exit.)

 

I did not need to update the BIOS.  I have installed, BIOS Version 1.08.

 

As it turned out, my first attempt was unsuccessful because the USB drive was formatted incorrectly (using the Rufus default setting of Partition Scheme = MBR partition scheme for BIOS or UEFI computers.)

Re: Yoga 2 11 USB boot

I found the answer. It was on Wikipedia of all places. I just looked at UEFI and there it is. Here is a link. Read the whole page then you will understand. I wont put a one sentence answer here because then some people may not get it right and this wiki explains it better than I can. read this so you can  do this

Re: Yoga 2 11 USB boot

The last supported version of that BIOS was in 2005 at version 10 so this is actualy old and IBM gave it up because of problems. Lenovo a off shoot is now learning what IBM all ready did away with.
