Installing dual boot Windows 8 on Lenovo S10-3t
UPDATE:I installed RTM release and works still fine on S10-3t (other than slightly skewed resolution). It’s still same install process as far as I can tell and you still need to increase resolution to make Metro apps work
See list of Windows 8 devices 2012 here: List of new Windows 8 tablets 2012
I installed Windows 8 Consumer Preview on Lenovo S10-3t and here is list of issues you might encounter and tips how you can improve setting this up. Big benefit of Windows 8 is that you will be able to get smooth zooming and navigation with IE10 and similar performance improvements you get for pdf with the optional reader download.

Installation new dual boot OS
First word of caution that OneKey Recovery program doesn’t work anymore when I installed Windows 8! So backing up with this program may not help to restore back to Windows 7. Therefore I decided to reinstall Windows 7 completely from scratch and remove one of the partitions so I can split the main drive in 2 and use new 2nd partition for Windows 8.
Here are steps how to do this and create new clean Win7 install and leave 1 partition for windows 8. Again warning: you will lose all data and OneKey backup won’t work anymore so backup your data on external drive.
- Create bootable USB drive (at least 4GB size) and copy all files from the Windows 7 Setup DVD to this drive. See how to do this here: http://www.ehow.com/how_8441030_create-boot-disk-windows-7.html
- Backup any data and programs installations on external drive. Note programs need to be reinstalled. Make sure you write down all program keys (e.g. Windows, Office, …)
- Download all necessary Lenovo S10-3t drivers first since Windows doesn’t have built-in driver for S10-3t wireless. Go to Lenovo support site and download at least following drivers on external drive (or use another computer):
- Intel Chipset Driver
- Intel OnBoard Graphics Driver
- Wireless Lan Driver (Intel, …)
- Broadcom Ethernet driver
- Lenovo Energy Management (to get Fn keys working for screen brightness and audio)
- Lenovo Active Protection System
- Lenovo Screen rotation
- Download Microsoft Surface Touch pack to get touch working for Windows 7: http://www.microsoft.com/download/en/details.aspx?id=17368
2. Create partitions and install new Windows 7
- Insert USB drive and reboot. If the USB doesn’t boot automatically go to bios setup (F2) and adjust boot order or use F12 to choose boot menu and then choose USB device
- When Windows 7 setup starts choose Drive options (advanced):
- Delete the large windows partition and 1 additional partition. I deleted the additional ‘Lenovo’ backup drive partition since I couldn’t use that anyway anymore for backup. Obviously you will lose all data so backup data first!
- For the just deleted windows partition choose ‘Extend’ and then choose the 2nd partition you deleted. This will merge the 2
- Choose ‘New’ for the merged partition and decide on % size. For instance 50% will leave half for the 2nd partition. Next I would label the volume. For example Win7. Repeat that for the remainder of the partition (choose 100%) for Windows 8
- Choose the Win7 partition for installation of Windows 7
- When Windows 7 setup restarts make sure you remove USB drive so you won’t end up in an endless loop:-)
- After Windows 7 is installed install all missing drivers you downloaded previously (in that order above). Note initially the device manager will show 3 unrecognized devices and you won’t have internet connection. After installing drivers you should see no errors anymore in device manager (power management, LAN and ethernet are the 3). You can install additional drivers and software optionally like screen rotation
- Restore any data and programs you want to install. I installed also K-lite Codec pack which will install Media player classic which gives you better performance and lower CPU usage for most video formats. For best battery performance in Media player classic use MPEG2 files and choose as render ‘Overlay Mixer *’. This will bring CPU down around 10% (you may get notification that aero is disabled but you can disable this message in notification settings).
3. Install Windows 8
- use Windows 8 DVD (or downloaded preview) and choose to install on the 2nd drive (new install)
Improving Windows 8 on S10-3t
- First problem is that the new Metro apps require at least 1024×768 resolution. One way to workaround that is to use downscaling. Only downside is that aspect ratio is not maintained on S10-3t but otherwise works well. Follow instructions how to enable this here: http://www.jessebandersen.com/2012/02/lenovo-ideapad-s10-3t-increase-dpi-and.html
- For previous issue consider creating a shortcut key to switch resolutions. You can use autohotkey for instance with change resolution script.
- Optionally you can download newer graphics driver driver on Intel site: GMA 3150. Although there’s an aspect ratio setting I didn’t have any luck keeping 16:9 ratio on S10-3t. I believe this setting is for upscaling resolutions only
- Note minimum resolution for split screen or snap app feature is 1366×768 so you won’t be able to display apps side by side on S10-3t. Looking forward when Lenovo Yoga will be available with proper 1600×900 resolution.
- Install the Lenovo power management driver. Then change in power advanced options: set max CPU to high. Second I’d change closing lid to hibernate and power to shutdown
- There’s no start menu and no shutdown options in Desktop mode (it’s in charm menu Settings/Power). That’s fine I think for S10-3t since you can assign shutdown to power button and hibernate for close lid action. But if you want to add shutdown shortkey button anyway in the taskbar follow these instructions: http://www.howtogeek.com/77061/how-to-add-shutdown-restart-sleep-to-the-windows-8-metro-start-screen/
- I would recommend adding some apps from the store. For instance navigation and zooming on the ‘Reader’ is pretty fluid on the S10-3t especially compared to Windows 7 Adobe reader.
- You can swipe from sides to open additional menu’s but on S10-3t the display edges are not flush so you may not find it easy to open the menu’s this way. UPDATE: turns out you start the swipe from the edge and then it works fine. Alternative is to use keyboard: use Windows key+Z to open app menu. Also Windows Key+X will open start menu. Or with the mouse move to corners: right side corners will open charm menu, upper left side opens switch app bar (move down to see all). Also right-click will open app menu as well
- Another shortcut key: Windows + I will open settings menu. Note that this settings menu is in the app context. So if you opened weather app and open this menu you can change weather app settings (e.g. Fahrenheit or Celsius)
- There’s no start menu anymore in desktop but there’s a trick to add it as a toolbar. See http://www.winbeta.org/guides/how-create-start-menu-toolbar-windows-8-consumer-preview
