Just got my ThinkPad Tablet 10 that came factory loaded with Win8.1 (32-bit). I want to re-image with Win8.1 (64-bit) image from USB install disk, but can't get it to "Boot" from this USB. I figured out how to connect an Anker 4 USB Port adapter, and have the KB/Mouse and USB stick boot and install with Win8.1 32 Bit USB (Company Image), but I cannot get it to "Boot" from a 64 Bit USB stick.
I can boot and re-image from this very same USB stick to several other UEFI BIOS based Lenovo and Dell machines, so I know the USB stick is fine. The UEFI BIOS is very 'unique' so I think there must be something special I need to do in order to make this work correctly...
Check if you have the right model to do this. There are two ThinkPad 10 models: 32-bit and 64-bit.
One quick way to find out what you have is to run System Information, which is an executable file to give Windows users a full list of their systems' hardware, software, resources and network settings.
To do so, run msinfo32 to open up System Information window to check the BIOS version.
For users running Windows 8/ 8.1 systems, move your mouse to the lower left corner of your screen.
Right click on the Start button and hit "Run".
If you install Win 7 systems in your ThinkPad 10, click on Start and then hit the "Run".
If you don't see this option, customize your Start Menu by right clicking on any area on the menu that appears after you hit the Start key.
Choose "Properties" after right click.
Click on Start Menu tab and then Customize, followed by checking the Run command option. Click on OK.
You will then see the Run... option available on your Win 7 system.
Now, click on that and type msinfo32 and click on OK to see what is in your system:
You can check the BIOS version from this window. Please note that this is just an example hence the BIOS version is not ThinkPad 10 BIOS.
GWETxxWW is 64bit GUETxxWW is 32bit
If you have the GUET62WW (1.62) model, which has 2GB RAM soldered into the Motherboard, it will not be able to run 64-bit OS. It is also easy to see this by holding Power + Volume Up, and looking at the System Info screen. It has all the firmware versions and features listed, plus what options are on and off.
