Lenovo Yoga Tab 2 SDXC UHS-1 Performanc​e

Hello everyone.
Recently I purchased a Lenovo Yoga Tab 2 10" Windows. (Yoga Tablet 2-1051F). I also purchased a new SD card with it (Kingston 64GB microSDXC UHS-1 Class 1 +).
My question is: Does this laptop officially support microSDXC UHS-1 cards?
If it is supported, the performance of these cards is bad at the moment. Will there be an updated driver or third party driver that might fix the performance problem?
Benchmark: Average read on the tablet: 10.7MB/s. Average read on another old laptop: 37.2MB/s.
Some extra information:
Hardware shows up as a: Generic SD64G SD Card
Hardware basically says it's a standard SD card, while on two other devices, it said that it was an SDXC card.
Hope anyone knows the answer to my problem.
Kind regards.

Yeh, I know, space on tabs is always a problem.
Edit:  That is just the adapter that is in the pic.
I have this one:
T430u, x301, x200T, x61T, x61, x32, x41T, x40, U160, ThinkPad Tablet 1838-22R, Z500 touch, Yoga Tab 2 Windows 8.1, Yoga Tablet 3 Pro

    Surprisingly, this overkill of a microSD card, performed just like the previous kingston (with an exception on the write speeds). This means that there is a hard limit on the performance of the sd card reader or the drivers of it. I've also tried a 32GB microSDXC card from my phone (Sandisk @ 30MB/s read on my phone), which also hung at around 11MB/s on the tablet. The tablet itself has not been changed and is basically running stock everything, so it's not being limited by any software or anti virus applications. Here is some feedback from the cards I tried: Samsung MicroSDXC Pro 64GB (Read: up to 90 MB/s, Write: up to 80 MB/s)Kingston 64GB microSDXC UHS-1 Class 1 + (Read: up to 90 MB/s, Write: up to 45 MB/s)Question to ask here is: What is the actual bus that the microSD card is connected to, is it UHS-1 or High Speed (USB 2.0 -ish)? Samsung - microSD card slot Samsung - USB 2.0 adapter Kingston - microSD card slot Kingston - USB 2.0 adapter Just like with the USB 2.0 adapter, the sd card reader seems to limit the performance incredibly. I've also tried what topmahof suggested (Enabling write caching), but I did not see any (at all) performance gains. What do you guys think, is this a hardware limitation? I seem not to be able to get any real performance out of this sd card reader. I hope we can get some Lenovo engineers to comment on this issue. The processor should be able to handle UHS-1, but if that is also implemented, I wonder.

  • CONNECT LENOVO YOGA 8 TAB TO VGA PROJECTOR

    I am using LENOVO YOGA 8 tablet. I want to connect it wirelessly using following prodecure,
    1) connect my VGA projector to the LENOVO CH580 HDMI to VGA Adapter, hence i get a HDMI port for my VGA Projector
    2) connect that HDMI Male port to HDMI Female port
    3) Connect the LENOVO WIRELESS DISPLAY ADAPTER WD100-SL-IN to this HDMI FEMALE PORT.
    4) Finally using CAST SCREEN function on my LENOVO YOGA TAB 8, to connect to this LENOVO WIRELESS DISPLAY ADAPTOR.
    Will this work or there is some better way to connect my VGA PROJECTOR to LENOVO YOGA 8 TABLET ?
    CH 580 HDMI TO VGA CABLE
    LENOVO WIRELESS DISPLAY ADAPTER WD100-SL-IN
    HDMI Male Female converter
    Solved!

    @Gamma30
    I do this regularly with my Yoga 10.  In UK with KitKat.
    I use a Tronsmart T1000 Miracast dongle which plugs into the HDMI socket of the TV, and has a separate USB lead which plugs into the TVs usb socket to supply power to the Tronsmart.  The key word in all this is "Miracast".  That is what the WD100 does but any Miracast dongle "should" work.
    To "turn on" casting on the Yoga you go to Settings-Display-Cast Screen then touch the three dots top right and touch "enable wireless display".  It will search for Miracast adaptors nearby.  The Tronsmart appears.  Touch it and select "connect".
    It can be a bit fiddly to get it to work first time, but persevere, it does work.  The Tronsmart, like a lot of these devices, uses EZCast software (you download it from PlayStore).  This allows you to configure the Tronsmart (confusing at first but eventually it makes sense).  Tronsmart has two modes, EZCast Mode and Miracast mode.  It has some interesting features in EZCast mode but you need to switch it to Miracast mode to get the casting to work.  You can change a Tronsmart setting to make it boot to Miracast mode by default.  This makes casting much easier in future.  If your initial experiance is like mine, expect an evening of puzzlement and iritation, but you'll get there in the end.  :-)
    Hope this helps.

  • Lenovo Yoga 2 13, Kali Linux 1.0.7, Ubuntu 14.04, Windows 8.1 install, config, and wifi fix.

    Lenovo Yoga 2 13, Kali Linux 1.0.7, Ubuntu 14.04, Windows 8.1 install, config, and wifi fix.
    I wanted to share an experience with everyone I hope will help others avoid what I have gone through the past 3 days. I bought a Yoga 11s that I loved but had some issues with the wireless, Lenovo being awesome replaced it with a Yoga 2 13. I love this laptop but ran into some issues with Linux install/wireless, which I wanted to show how to resolve in one place. Hopefully this will help someone else get through this quicker
    I am going to try and write this for someone with little Linux experience, if I miss the mark please let me know and I will clarify the best I can.
    For work I need Windows 8.1 and Kali Linux, while for home I prefer Ubuntu.
    My Yoga 2 13:
    I5 1.6 ghz
    8 GB ram
    256 GB SSD
    ORANGE!
    My requirements: 
    I need Windows
    I need Kali Linux (livecd, even with persistent mode was not an option as it would not save the wireless fix or system updates) – I would also like this on a USB drive and not the internal SSD
    I would like Ubuntu
    Needed to do this:
    1. 2 USB thumb drives (at least 8gb in size each) I used 2 Leef Supra 32GB drives. They are my favorite right now and are only about $27 at amazon.
    2. Phone that can USB Tether or a USB Ethernet card (External USB wireless will show as "Hardware Locked"). Again you can pick one up for sub $10 if you need the USB Ethernet route. I used my Galaxy S5, you will need to download 200-300 mb of items through this so make sure you have the data if you go that route.
    3. You may be able to get a USB wifi card to work if you do the following after boot. This only worked once for me.
                    a.Type ‘sudo rmmod iwlmvm’
    b.Type ‘sudo rmmod iwlwifi’
    4. ISOs of Ubuntu and Kali Linux (I used Ubuntu 14.04 and Kali Linux 1.0.7)
    5. Software to unzip the ISOs. I recommend 7-ZIP and will be referencing this in this guide.
    6. I will include the EFI boot files and the WiFi fix files if I can attach. Otherwise I will provide a link to them.
       Link: https://www.dropbox.com/s/puxnnoft3gn2b6l/WiFiFix.zip
    Recommended (these are just in case you corrupt something making your system not see any OS
    1.  I would call Lenovo beforehand and get a set of recover disks (this will take 2-3 days)
    2. In the meantime a USB Windows 8.1 or 8 ISO (the repair feature may save you)
    *Note: At many points in this guide I detail steps and commands. Please double check that you understand the step before proceeding. There are multiple points where a mistyped command or clicking the wrong option will cause your entire system to fail and you will need to reformat the entire drive and start over. This also will make One Touch recovery not work. Proceed with caution.*
    I did not need to disable ‘secure boot’ to do this, but keep in mind that you may need to.
    Steps:
    First let’s go through the installs, and then we will go through grub config and wireless fix
    1. In Windows scroll to computer and right click, select manage.
    2. Go to “Disk Management”
    3. Select the main HDD (notice Lenovo puts a stupid number of partitions on here)
    a. I deleted the D: drive on here, if you do this make sure to copy the drives over to your main C: drive. You will want to run each of the installers and repair the drivers after.
    4. I used the space from the D: drive and pulled a little more creating a 50 GB partition for Ubuntu and my swap file
    a. You can also add more space by right clicking your C drive and selecting shrink
    b. Do not format the partitioned data as this will make identifying it later much easier.
    5. Open a command line
                    a. Swipe from the right of the screen and select search
                    b. Type ‘cmd’
                    c. right click and select ‘run as admin’
    6. For Ubuntu: Type ‘diskpart’ into the command line
                    a. type ‘list disk’
    i. You should see 2-3 disks depending on if you have one or both usb drives in the laptop at the time. I would suggest only doing 1 at a time so you don’t lose track.
                    b. type ‘select disk $’ (Replace the $ with the number of the drive)
    c. ***** Before proceeding make sure you have the correct drive selected or you can ruin your Windows install and Lenovo one touch recovery will not fix it since we have changed the partitions *****
    d. type ‘clean’
    e. type ‘create partition primary’
    f. type ‘active’
    g. type ‘format  fs=fat32 quick’
    h. type ‘assign’
    i. type ‘exit’
    6. For Kali Linux: Type ‘diskpart’ into the command line
                    a. type ‘list disk’
    i. You should see 2-3 disks depending on if you have one or both usb drives in the laptop at the time. I would suggest only doing 1 at a time so you don’t lose track.
                    b. type ‘select disk $’ (Replace the $ with the number of the drive)
    c. ***** Before proceeding make sure you have the correct drive selected or you can ruin your Windows install and Lenovo one touch recovery will not fix it since we have changed the partitions *****
    d. type ‘clean’
    e. type ‘create partition primary size= 3272
    f. type ‘active’
    g. type ‘format  fs=fat32 quick’
    h. type ‘assign’
    i. type ‘exit’
    j. By doing this we can maintain a portion of this drive as the install CD and still have linux install/ liveCD if we need to run it on another machine.
    7. At this point the drive is ready to have the contents of the ISO copied over.
    8. Right click the ISO and select 7-zip then ‘zip to /’ This should unzip the ISO to the location of the ISO into a folder named exactly the same as the ISO.
    9. Once this is done for Ubuntu ISO it is done
    10. Kali requires a little bit more to be ready
                    a. Kali will need some files added for EFI boot. --$--
                                   i. Thanks to: https://forums.kali.org/showthread.php?271-How-to-EFI-install-Kali-Linux
                                   ii. EFI files are located within the wifi fix folder https://www.dropbox.com/s/puxnnoft3gn2b6l/WiFiFix.zip
    11. Now let’s start with Ubuntu
    Ubuntu install
    1.     Place USB drive into the laptop and press the “Lenovo boot” button next to the power button
    2.     Select ‘Boot Menu’
    3.     Select ‘EFI USB Device (Name of drive)’ Mine stated Leef Supra
    4.     Select ‘install Ubuntu’
    5.     Go through the Ubuntu install until you get to select the install drive
    6.     Once you get to the install portion it will ask you to select from one of 4 options. Select ‘Manually select partition’
    7.     Select the “Free Space” where we opened up some of the drive
    8.     You will need to create 2 partitions, I usually create the swap partition at the end of the drive
    a.     First I create the swap
                                              i.    Set at the end of the drive
                                             ii.    Set size to 1024 mb
                                            iii.    Set type to ‘swap’
    b.     Second create the ext 4 partition
                                              i.    Set to beginning of drive
                                             ii.    Set to remainder of the space
                                            iii.    Set type to ext4
                                            iv.    Set mount point to /
    9.     Finish the install and boot into Ubuntu
    10.   You will notice that your wireless is ‘disabled by hardware’ This is fine for the time being and we will worry about this after the kali install. If we fix it now for some reason after installing kali we get the error again and would just need to fix it again.
    Kali Linux install
    1.     Place USB drive into the laptop and press the “Lenovo boot” button next to the power button
    2.     Select ‘Boot Menu’
    3.     Select ‘EFI USB Device (Name of drive)’ Mine stated Leef Supra
    4.     From the grub menu select ‘install kali linux’ both graphical and text work. I much prefer text install
    5.     You will get a few errors through the install but that is fine
    6.     The first we see is about network hardware and ‘load missing firmware from removable media?’ – Select ‘no’
    7.     Then select no ethernet card
    8.     It will have you name your machine then it will ask you for the root password
    a.     If you want to just use root *not recommended* place the password here
    b.     If you wish to use a non-root account then leave these blank and it will ask you for a name, username, and password of the new machine *Very Recommended* - this will also add this user to the sudoers file
    9.     It will then ask you to ‘partition disks’
    10.   Select manual
    11.   Now here is where it can get a little confusing so read twice click once
    12.   Select the USB drive from this list
    13.   Mine shows up under (sdb) – Leef Supra
    a.     It could be sdc, sdd, sde, etc… depending on how many drives you have plugged in.
    14.   You should see one primary drive that is 3gb or so that is formatted as FAT32. – DO NOT TOUCH THIS PARTITION!
    15.   You should see the remainder of this drive as ‘FREE SPACE’ select that
    16.   Create a partition at the end at size 1024mb and swap
    17.   Then create another one for the remainder of the drive and set it to ext4 with mountpoint of /
    18.   Continue through the install after you should see an error warning you that ‘you may not be able to boot’ that is fine, select continue
    19.   Then select from the menu of all the options ‘continue without bootloader’
    20.   It should finish up then reboot on its own.

    First setup/boot/fix grub
    1.     You should  be able to boot up into GRUB2 menu now.
    2.     You may not see kali linux in this menu (make sure you have your towel and don’t panic!)
    3.     Boot into Ubuntu
    4.     Once you log in you should see that you still cannot use wireless due to being locked by hardware
    5.     This is expected
    6.     Let’s fix grub then we will come back to fixing wireless
    7.     Plug in your device to connect to the internet (USB Tethering or USB Ethernet)
    8.     Once you verify that you now have an internet connection run the following from terminal
    a.     ‘sudo add-apt-repository ppa:danielrichter2007/grub-customizer’
    b.     ‘sudo apt-get update’
    c.     ‘sudo apt-get install grub-customizer’
    9.     You can also edit the grub.cfg manually if you know what you are doing… I did not
    10.   Open grub  customizer
    11.   It should auto populate and you should see ‘debian (kali linux)’ somewhere in the list
    12.   It should be mounted to /dev/sdb2 or /dev/sdc2 depending on how many devices you have
    13.   At this point go ahead and save
    14.   Reboot and test that you can get into each OS
    15.   This is where my inexperience got me. I spent 2 of my days so I am including this error: If when you boot into Kali you get an error somewhere that says ‘/bin/sh: can’t access tty: job control turned off’ look above it for an error that looks similar to ‘ALERT! /dev/sdc2 does not exist. Dropping to a shell!!’
    a.     That error is due to the mount point being incorrect in grub, reboot and from within grub highlight the kali boot. Press ‘e’ then towards the bottom you should see ‘root=/dev/sdc2’ change this to ‘root=/dev/sdb2’ again the number doesn’t matter just make sure it stays the same.
    b.     Press F10
    c.     If this boots fine then you will need to go back and fix the grub.cfg or load into Ubuntu and open grub customizer again, it should fix this
    16.   Now you have 3 working OS on the machine with one being on a USB! Congrats!
    17.   You can remove the USB with no worry of screwing up your install, but you will not be able to boot into Kali Linux until you replace it. I would suggest only removing it and replacing it while the machine is powered off, but that’s just me.
    Fix Wireless
    Now is the time to do what probably ¾ of you came here for. FIX THE DANG WIRELESS. This is a huge problem from Lenovo’s side that I hope they realize how important Linux is and will fix. I won’t hold my breath though.
    Log into Ubuntu : This is well documented in the following forum post on page 3 by user Haohe:
    http://ubuntuforums.org/showthread.php?t=2215044&page=3
    His has you download quite a large file, mine should be much smaller.
    https://www.dropbox.com/s/puxnnoft3gn2b6l/WiFiFix.zip
    1.     Download the attached package with the fix.
    2.     Connect your USB internet device (tether or ethernet)
    3.     Place the packages somewhere easy to access, in this example I will place them under ~/Desktop/WiFiFix
    4.     Type ‘cd ~/Desktop/WiFiFix/’
    5.     Now we need to prep the tools we need.
    6.     Type ‘sudo apt-get update’ – we did this before, but you know, just in case
    7.     Type ‘sudo apt-get install linux-headers-`uname –r`’   Note around uname-r they are the ` symbol not the ‘ this is located just above the tab on the same key as ~.
    8.     Type ‘make’
    9.     Type ‘sudo cp /lib/modules/3.13.0-24-generic/kernel/drivers/platform/x86/ideapad-laptop.ko ~/ideapad-laptop.ko.backup’
    10.   Type ‘sudo cp ~/Desktop/WiFiFix/ideapad-laptop.ko /lib/modules/3.13.0-24-generic/kernel/drivers/platform/x86/’
    11.   Type ‘sudo modprobe -r ideapad-laptop’
    12.   Type ‘sudo modprobe ideapad-laptop’
    13.   Type ‘sudo rfkill unblock all’
    14.   Type ‘sudo modprobe -r ideapad-laptop’
    15.   Type ‘sudo mv ~/ideapad-laptop.ko.backup /lib/modules/3.13.0-24-generic/kernel/drivers/platform/x86/ideapad-laptop.ko’
    16.   Next we need to blacklist the ideapad module
    17.   Type ‘sudo echo 'blacklist ideapad-laptop' > /etc/modprobe.d/blacklist-ideapad.conf’
    a.     The first time I tried this it wouldn’t work. So I did the following
    b.     ‘sudo touch /etc/modprobe.d/blacklist-ideapad.conf’
    c.     ‘sudo vim /etc/modprobe.d/blacklist-ideapad.conf’
    d.     Enter     blacklist ideapad-laptop
    e.     Exit and save
    18.   Reboot your Yoga 2 13
    19.   Boot into kali and see if you have wireless, if you do then you are done. If not we will need to repeat this process with one small little change.
    Kali Wifi Fix
    1.     Copy the sources.list from the package provided
    2.     Replace /etc/apt/sources.list with the included
    3.     Some of the file path changes but the process remains the same from here.
    Congratulations you now have 3 OSes one portable to other machines and working wifi!
    Thank you

  • Lenovo Yoga 2 Pro: WiFi doesnt work after driver upgrade

    After experiencing Wireless issues I tried to upgrade my Lenovo Yoga 2 Pro 13" with Windows 8.1 64Bit to the latest drivers from the lenovo support site.
    Ever since I cannot connect to the WLAN anymore. What puzzles me is that the driver status in the device manager shows a different driver version than what I have installed (uninstalling the driver and reinstalling it doesn't change anything here).
    What puzzles me is the Lenovo Website shows driver version 16.6.0.8 (released 25.Jan.2014, see link below), whereas my system display version is 16.6.2.1 (dated 31.10.2013). Hence I thought I have another version from somewhere else on my and removed all driver versions I could find.
    Checking driver details I get the follow file versions:
       C:\windows\system32\drivers\NETwbw02.sys    version 16.6.2.1 Intel, dated 2011
       C:\windows\system32\drivers\Netwfw02.dat       no version or publisher
       C:\windows\system32\drivers\vwifibus.sys          version 6.3.9600.16384 Microsoft
    Still, whenever I deinstall the driver, install the files from lenovo and click "Detect new device" my system pulls the drivers as listed above and is incapable of connecting to any WiFi.
    Windows 8.1. shows no connections available and doesn't connect anymore.
    How can I get my WLAN back?

    hi Florian,
    If Windows Update is configured to automatically fetch updates from Microsoft then the machine most likely have installed the Intel driver update for Intel(R) Wireless N-7260 as discussed in this article (which explains the different driver versions).
    Things that you can try:
    1. If the machine comes with the Intel(R) Wireless N-7260, navigate to:
     - Device Manager 
     - Network Adapters

  • Elements12 program formated very small on my Lenovo yoga

    I recieved the Adobe Elements 12 photoshop as a christmas present with the new lenovo yoga laptop. When I installed the program on the computer I opened it and it was very small text and tabs. I tried to enlarge the text and the rest of the program by zooming in and out like I do on the rest of the programs and apps and nothing worked. How can I enlarge the program without making the graphics worse?

Although the widget is made for the lenovo launcher, its not appearing in options, any idea how to make it appear n the default launcher? the widget is used to find installed apps.
    2)There is a breathing light while charging, around the power button, why don't the developers use it as notification light? May be a new firmware update will do the trick, but whom to contact for the suggestion?
    3)double tap screen lock is there, how about double tap activation of screen?

  • Otg support for lenovo yoga 8

    Hi,
    I tried 2 to 3 otg cables for my tablet to use standard keyboard and mouse but otg icon is not displayed in my tablet. Can you suggest me otg cable that is compatible with lenovo yoga 8 tab.
    Thanks for your help in advance.
    Regards,
    Naveen

    You don't say what firmware version is currently installed, but after I received the  _028_  OTA update for my Yoga 10, I lost all USB functionality, including otg. I also lost the ability to charge while the unit was on, but I may have found a work around for that. I'll be documenting that in a separate thread for others who experienced "slow charging" after the OTA KitKat update(s).

  • [REQUEST] rtl8723au_bt bluetooth driver for lenovo yoga 13

    Hello.
    I have a lenovo yoga 13 laptop with 8723 wireless card.
    Wifi is working bacause of dkms-8723au-git package. As I know, in 3.15 kernel it will work out of the box and lwfinger will no longer maintain this source code.
    Bluetooth is not working and there is no bluetooth driver in aur. It is required to install another package from here https://github.com/lwfinger/rtl8723au_bt.
    I cannot build this package, because when I run make command it ends with error make[1]: *** /lib/modules/3.14.4-1-ARCH/build: No such file or directory. Also there was written about no dkms support in code. But I cannot fix it, because I am still noob in Archlinux. And for some reason it is written "Support kernel version 2.6.32~3.13.0" in readme.txt. I have already 3.14.4-1-ARCH kernel.
    Could anyone help me to fix that and make aur package for other people to get  bluetooth work on lenovo yoga 13?

    I think bluez5 is ok, because when I run bluetoothctl it can detect my cluetooth controller now. However, I cannot start working with it

  • Trouble with Adobe Reader Touch on Lenovo Yoga Pro 2 in tablet mode. Pdf shows up as blank pages.

    I have a Lenovo Yoga Pro 2 and when I change it to tablet mode and use the Adobe Reader Touch app, my pdf shows up as a blank page. I have installed other pdfs in the past and those show up fine. However, as of three days ago, whatever pdf I install shows up as blank on my screen. Is there a solution to fix this?

    Could you please share your test file?

  • Lenovo Yoga with Windows 8 Pro, Office 2013 and Visual Studio

    For you developer types, I just wanted to post a message and let you know my experience with Lenovo Ideapad Yoga 13 as a development machine. I bought Lenovo Ideapad Yoga 13 from Bestbuy for $999.99. As expected, it came with a crap ton of bloatware installed by Lenovo.
    Here is a summary of what I did to it (I take no responsilibity for accuracy of below information. You are on your own if you decide to follow them. I am just putting this down from my memory so that I can look it up in the future if I ever need to do this again).
    INITIAL CLEANUP
    Installed Lenovo hotfix for partition cleanup/merging: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS033035
    Installed Lenovo Touchpad driver fix.
    CAUTION: I take no responsibility for below steps. I am writing them from memory and if you decide to follow them and end up making your machine unusable, you are on your own as Lenovo might not honor your warranty.
    BACK UP ENTIRE DISK (requires an empty USB flash drive for booting and another external USB drive for backup)
    Copied Drivers from D_Backup folder to the external USB hard drive (plugged into USB 3.0 port).
    Installed Paragon Backup & Recovery 2012 Free: http://www.paragon-software.com/home/br-free/
    Created Paragon Backup & Recovery boot USB flash drive with default Linux recovery environment option (flash drive plugged into USB 2.0 port).
    Shutdown Lenovo Yoga.
    Plugged in the Paragon Backup & Recovery boot USB flash drive (USB 2.0 port). 
    Pressed the one key recovery button (next to power button). Went to BIOS.
    In the BIOS, enabled Legacay mode and made Legacy high priority and saved the changes.
    The machine booted into Paragon Backup & Recovery mode. From there, made a backup of entire disk to the external USB hard drive.
    Shut down the machine, pressed the one key recovery button (next to power button). Went to BIOS. Turned off Legacy mode and switched back to UEFI boot mode and saved the changes and restarted the machine.
    Logged into the machine and verified that everything was good and checked the external USB drive to verify that the backup image was present.
    MAKE WINDOWS 8 PRO BOOT USB FLASH DRIVE (requires a second empty USB flash drive and a second computer with Windows 7. This USB Flash Drive has to be between 4GB to 32GB as Windows won't format 64GB flash drives to FAT32 mode)
    (Note: I installed Windows 8 Pro in UEFI mode. See http://pcsupport.about.com/od/windows-8/a/install-windows-8-usb.htm)
    You need a licensed ISO image of Windows 8 Professional Full version (not the upgrade version) from your MSDN or Technet subscription or create an ISO from the Windows 8 Pro full version DVD.
    Download Windows 7 USB/DVD Download Tool on the computer with windows 7.
    Plug in the second empty USB flash drive (has to be at least 4GB but less than 32GB) into the computer with Windows 7.
    Using Windows 7 USB/DVD Download Tool and the ISO file, create the Windows 8 Pro bootable USB Flash drive.
    Create a new folder on your computer disk, for example, C:\WIN8USB.
    Copy all the files from your USB flash drive to the newly created folder (created in the previous step).
    Right click on the USB drive icon in Computer window and select “Format…” from the context menu. Make sure you select “FAT32 (Default)” in “File system” drop down menu. Click “Start” and wait till the drive gets formatted. This step is needed because NTFS is not readable by BIOS in UEFI boot mode. During formatting, MBR is preserved so the thumbdrive is still bootable.
    Copy all the files from the folder you created earlier (C:\WIN8USB, for example) to the formatted drive. Your Windows 8 installation USB drive is ready to install in UEFI mode.
    WIPE THE DISK PARTITIONS
    Shut down the machine, pressed the one key recovery button (next to power button). Went to BIOS, enabled Legacay mode and made Legacy high priority and saved the changes.
    Booted into Paragon Backup & Recovery boot USB flash drive again. This time, I deleted all partitions on the primary disk (Disk 0). CAUTION: This WILL wipe your hard disk and will make your machine unusable!!! 
    Shut down the machine, pressed the one key recovery button (next to power button). Went to BIOS. Turned off Legacy mode and switched back to UEFI boot mode and saved the changes and shut down the machine.
    At this point, the disk is wiped clean. All factory installed software and recovery partitions are gone!!!
    INSTALL WINDOWS 8 PRO
    Plug in the USB Flash Drive with Windows 8 Pro install files.
    Windows 8 Installer would show the unallocated disk space. I can't remember the exact details but either I had to click on Delete or New to delete and then create a new GPT partition. The entire partition was about 119GB.
    From that point, follow the Windows 8 Pro installation steps.
    After booting up into Windows 8 Pro, plug the external USB drive that had the drivers folder backed up from D_backups.
    Install all the drivers from this folder (I was able to install everything except for one Intel fast boot one because of missing partition but my Yoga still boots up just as fast).
    Go to device manager to check and everything should be good now.
    Run Windows Update.
    You should now have about 101GB free on C: drive!!
    INSTALL VISUAL STUDIO, SQL SERVER and OFFICE 2013 ON LENOVO YOGA 13
    I installed the following in that order:
    Microsoft SQL Server 2008 R2 Developer edition (I installed all components, everything!). Then I installed latest service pack.
    Microsoft Visual Studio 2010 (I installed all components, everything!). Then I installed latest service pack.
    Microsoft SQL Server 2012 Developer edition(I installed all components, everything!). Then I installed latest service pack.
    Microsoft Visual Studio 2012(I installed all components, everything!)
    I ran Windows update and also installed Nov 2012 updates of SQL Server Data tools.
    I then installed Office 2013 Pro Plus.
    MAKE LENOVO YOGA 13 MORE SECURE
    Go to Control Panel and enable Windows Defender (it is included by default in Windows 8 and is anti-virus and anti-malware solution)
    Enable full hard-disk encryption using BitLocker feature of Windows 8 Pro. Since Lenovo Ideapad Yoga 13 doesn't have hardware TPM, you have to enable password based option. For this, follow the steps here: http://rics.partners.org/show_article.php?id=274. 
    Basically, you go to GPEDIT.MSC and Open Computer Configuration => Administrative Templates => Windows Components => BitLocker Drive Encryption => Operating System Drives. From the right pane double-click "Require additional authentication at startup. Select Enabled radio button and check the box for "Allow BitLocker without a compatible TPM...". Click OK and close the policy editor. Then Right-click your C drive in the Computer folder, click Turn on BitLocker. Then select Enter a password instead of USB option. Then provide a strong password (make sure to write it down and put it in a SAFE place, if you lose the password, no one can boot into your hard disk). Then select Save to a file and save it to the External Drive. Select "Encrypt entire drive...", click Next. When this is done, you will get a pop-up on the lower-right a prompt to restart the computer. Restart your PC. Enter the encryption password created earlier. If you are successful in getting into Windows, you're all set.
    I also hooked up to Skydrive and used BoxCryptor to encrypt my files in cloud.
    The available free disk space should now be about 54GB.
    I verified that Lenovo Yoga 13 works like a champ with no slowdown with Visual Studio 2010, Visual Studio 2012 and SQL Server Management Studio open simultaneously and Bitlocker enabled!
    The keyboard right SHIFT key is small but other than that, it can work as a great portable development machine and Microsoft Reader is great for reading PDF eBooks.
    So if you are a Developer on Microsoft platform, go right ahead. Lenovo IdeaPad Yoga 13 is great for running Visual Studio 2010 and Visual Studio 2012 (1600x900 resolution is totally usable) while on the move. Since I have only had this machine for a few days, I can't tell much about the long term reliability.
    Solved!
    Go to Solution.

    Thank you for posting this. I am in this exact situation. I purchased a yoga 13, and installed Visual Studio Express 2012 for Windows Phone. As it turns out, the Windows Phone Emulator ONLY works in a Windows 8 Pro environment. Since the Yoga doesn't have a disc drive, I shared my W7 computer's cd drive, then put in Windows 8 Pro, so that it could install onto the Yoga. Well, after the installation was done, I tried running my program again and ran into the same issue. It prompted me that my environment must be Windows 8 Pro! I thought that Windows 8 Pro already installed but, what confuses me is that I see no indication that Windows 8 Pro installed. When I go to the System Window, it reads: "Windows 8". Should it read Windows 8 Pro?
    Ultimately, I'd like to know, are you able to execute the Windows Phone Emulator? I'm not sure as to whether the Yoga has the hardware capability (needs to be SLAT enabled or something like that?), I HOPE it is able to, and judging by your post, it seems like it but I'd love to know your perspective on my approach.
    Please let me know if this makes sense, as I'm new to this kind of thing but really want to start development for Windows Phone.
