SOLVED: How to Install Windows 10 On An Asus T100 Transformer

There are four quick points to get through if you are trying to run Windows 10 on an Asus T100:

1. You have to run 32 bit at least for now as the UEFI (new BIOS) that Asus built does not support 64 bit (as of October 26, 2014)
2. Windows 10 WILL upgrade from your old Windows 8.1 BUT I found the machine slow and well, not quite right, so wiped it out
3. If you wipe out the factory image you will lose the drivers, but all of the drivers CAN be found on one of two sites:
   1. The Asus T100TA Driver package.  Click CHIPSET > SOC DRIVER PACKAGE (with VGA AND CAMERA)
   2. The Dell Venue 11 driver package
4. After the install and driver updates were complete, I was saddened to see the Tiles/Modern UI/Metro start screen… so I changed it!
   1. Right click on the task bar and select Properties
   2. Click the START MENU tab and select USE THE START MENU INSTEAD OF THE START SCREEN

Below are the steps I followed to complete the install:

1. I flashed the BIOS/UEFI to the most current but I do not think that was required.
2. Download 32 bit Windows 10 from Microsoft and make a DVD or use the install DVD if you have a release version
3. Entered the BIOS of your Asus T100 and set it to boot to the USB DVD player I had plugged in
4. Run through the install wizard as you would expect but delete ALL the partitions
5. Complete the base install and sign in
6. Launch DEVICE MANAGER and notice that there are about a dozen pieces of hardware that did not get installed and now show as the dreaded UNKNOWN
   1. Fortunately the wireless driver DID get installed so you can surf and source drivers easily
7. Download the Asus T100TA Driver package for Windows 8.1 and extract the files to a new folder your create named C:\DRIVERS
8. Right click on any of the UNKNOWN devices and select UPDATE DRIVER then point it to C:\DRIVERS
9. Repeat step 9 until you are done
10. Expand DISPLAY ADAPTERS, and right click on MICROSOFT BASIC VIDEO ADAPTOR, and force it to update from the Asus Driver package.
    1. If you leave your T100 with the MS BASIC ADAPTER, the computer will function but it will be clunky and feel slow… so fix it!
    2. When you are done it should read INTEL HD GRAPHICS
11. I also then installed, Office 2013, Adobe Reader because I hate the integrated one along with Microsoft Photo Gallery and Movie Maker.

Note that in my case I did not find the Asus Drivers until after I had installed the Dell drivers using the process in steps 7, 8 and 9.  The point being if you are missing any drivers, give the Dell download a shot.

In the end I found that the Video Driver, G Force Sensor and Camera were the biggest problems but the Asus T100 Windows 8.1 SOC package contained all I needed and now there are no UNKNOWNs in my Device Manager.

The Asus T100 runs Windows 10 beautifully.

Enjoy!
