    Hi everyone,

    I've recently did a clean install and seem to be having issues with a UEFI boot only option with my X220.

    When I installed Windows 8 last night I had to select 'Both' in the UEFI/Legacy Boot' option in order to boot and do a clean install from the Windows 8 installation DVD.

    Now after the Windows 8 install when I select 'UEFI Only' in the UEFI/Legacy Boot option, I get the 'Boot Menu' screen with an option to boot from my SSD and the Windows Boot Manger, however neither of these options work.

    The BIOS settings are set to boot to 'Both' with UEFI as the first preference and this seems to be working ok.

    Is it possible to have a UEFI only boot option with Windows 8 and my X220?

    Thanks

    Rambler

    I have a UEFI only boot with windows 8 on my X220, but I didn't install it from the DVD, I put it on a USB drive (didn't use the official windows 7 tool because you cannot format your drive in GPT with it). Installing from a DVD bypasses that problem though so I'm not sure what your issue is.

    The issue is that for some reason my X220 cant boot to any type of device (SSD, DVD or USB) with the boot option set to UEFI only.

    My X220 will only boot when 'Both' is selected.

    The Boot Menu will display once F12 is pressed however none of the devices will boot when selected.

    Download ISOtoUSB: ISO to USB

    Download Windows 8 through the upgrade utility, and save the ISO somewhere.

    Run ISOtoUSB, select Windows.iso, and set the format for the memory stick to FAT32 (you can't make the memory stick using the Microsoft utility because that makes an NTFS formatted stick, which UEFI cannot boot)

    Set to UEFI only in UEFI/BIOS setup.

    Should then boot from the memory stick. I used gparted and did an ATA secure erase to totally wipe my SSD first, then Windows set up the disk using GPT instead of MBR.

    Then install. I couldn't boot from the DVD in UEFI mode, but this worked for me.

    Thanks iphetamine and dbman190. Reps added.

    Looks like a USB formatted to FAT32 will work, and explains why media with different file systems dont (DVD-UDF and SSD/USB-NTFS).

    Since Im going to reinstall windows 8 over my current Windows 8 installation, does anyone know what process I should follow seeing that the Windows 8 installer will check for a Windows 7 installation prior to installing?

    I like the idea of nuking my current installation with gparted and then doing a clean install with UEFI, but it doesnt look like the Windows 8 upgrade installation will allow this.

    What are you using the beta drivers for? The X220 Driver Matrix has a bunch of windows 8 drivers available, including the SD card reader :)
