Want to install Windows 8.1 Enterprise on my Yoga 2 10 tablet

Question

I would like to install Windows 8.1 Enterprise on my Yoga 2 10 tablet. The tablet came with Windows 8.1 with Bing preinstalled. This upgrade will require a full reinstall as there's no upgrade path to the Enterprise from the preinstalled version. Unfortunately, there are no dowloads for drivers or the bundled software on the Lenovo support site for the Yoga 2 10 tablet (1051F).  Will the drivers & bundled software eventually be available for download or are they something I need to purchase?

Hi all,
I finally figured it out. I have the 13" with the 64GB drive Yoga 2 Tablet.
Here's what I did.
1. I used Double Driver to scan my system and backup ALLof the original drivers to a flash drive.
2. I attached a USB 2.0 hub (Must be 2.0 to avoid additional driver issues during 8.1 enterprise install)
Attached a standard keyboard, mouse, and 8GB flash drive with Windows 8.1 Enterprise on it.
(the flash drive must be  a standard flash drive and must be created to booth via UEFI. I used ISO2Disc to do this)
3. After I was sure the drivers backed up I shrunk the partition of the current windows drive to 20GB and created a new partition
4. I restarted and boot into the bios and turned secure boot OFF(after you push restart hold the volume up button until it brings you to it. Here you'll find the boot manager, BIOS, etc.)
5. I then restarted again and boot to UEFI USB that had my windows 8.1 enterprise (x86 only - x64 is not supported with these devices/BIOS that I know of)
I installed 8.1 Enterprise on the new partition that I'd just created out of the remaining space I took from the original windows install - It would not allow me in any way to install 8.1 OVER the previous windows install.
6. I installed windows as normal and then used Double Driver to do a restore of ALL the previous drivers I captured from the other partition with windows on it. I had to click through several "Publisher not found, do you want to install anyway?" prompts, but it worked out really well.
7. I did a restart and ensured that everything continued to work as expected.
8. Then I booted back into the Enterprise install and in Disk Management deleted the old partition of the previous windows install and recommisioned it as a new simple volume.
*At  this point there are likely tools that would combine the partitions for me but I didn't have one nor could I get any good recommendations so I preceded to do it the only way I knew how and went to step 9.*
9. I went back and repeated Steps 5-7 but this time installing Enterprise on the Original partition.
10. After a restart and ensuring the drivers worked I did all the windows updates and checked to make sure everything was good.
11. I used disk management to delete the FIRST install of Enterprise and then expanded my SECOND install of enterprise to reclaim the unused space.
12. Installed all my normal programs, joined to domain, and treated it as a normal computer from here on out.
Note - I left the 100MB EFI untouched as I'm pretty sure this is what fuels the BIOS and boot. Also the ~5GB Recovery partition untouched in case I ran into any problems and needed my original factory image back.
