Cannot install windows 7 (downgrade from Windows 8.1 on Lenovo U330 Touch)

Hello.
I wanted to downgrade my new Lenovo U330 Touch from Windows 8.1 to Windows 7 (x64 Home Premium). I followed the instructions from this previous forum post...
https://forums.lenovo.com/t5/IdeaPad-Y-U-V-Z-and-P-series/U330-Touch-Downgrading-to-Windows-7/m-p/15...
I accidentally deleted the partition with Windows 8.1 on it by mistake. Good riddance to it.
Now, when I try to install Windows 7 from the boot sequence, I get the message saying that "Windows cannot be installed to this disk. The selected disk is of the GPT partition style".
How do I install Windows 7 please?

I have tried this a few months ago. You can study the steps and try it on your unit.

    I see others on this forum have had similar problems going back to windows 7. I tried some of their driver solutions that were posted, but to no avail. Can I get some help? Maybe some links to where I can find drivers to help me? Windows update cannot find and automatically install replacement drivers.

    Hi:
    Looking at the hardware specs for your model you should be able to use all of the W7 x64 drivers and software from the HP Probook 450 G2 on your model except the BIOS and firmware files.
    Your model uses the Intel HD graphics driver and the Realtek RTL8188EE wireless card driver.

  • Downgrading from Windows 8.1 x64 to Windows 7 Professional 32bit on HP 15-r036tu

    Hello,
    Is that possible to downgrade from factory installed windows 8.1 to windows 7 on HP 15-R063TU  Notebook?
    Please guide for neccesary steps at earliest.

    Why 32 bit? I do not recommend that but here is a past thread dealing with your exact question:

    The "downgrade" will not be free. You will have to buy Windows7 or have a real licensed copy available. 

  • Downgrade from Windows 8.1 enterprise to windows 7 Ultimate or Professional

    I have installed windows 8.1 and am not happy neither with its performance or it's UI; I have my own copy of Windows 7 Ultimate can I downgrade from Windows 8.1 to Windows 7 Ultimate? I need to keep my applications and files.

    Hi,
    Like Carey said, you need to format the whole drive and do a clean install. The most important is don't forget do a backup in an external hard drive. You will be need to restore it after roll back to Windows 7.

  • HT1926 Cannot install itunes Error 7, windows error 1114

    Cannot instal Itunes, Error 7, window error 1114 ???

    Hi!! I finally found a solution
    I´m Sure this one will work for everyone
    -First you have to uninstall all Apple Software using Control Panel
    -Download Unlocker Software from softsonic heres the link http://tinyurl.com/3e8gj2h
    or google it
    -Install Unlocker
    -Go to Start and type this in search: %programdata% 
    -ProgramData window will open, so find apple folders
    -Right click in each apple folder and find Unlocker in the options
    -Choose Delete each apple folders (with unlocker program)
    -Go to My PC, C Local Disk and find Program Files
    -Look for Apple folders and Delete them (with Unlocker)
    -Find a Folder (in Program Files) called Common Files
    -Delete all Apple Folders (in common files) with Unlocker
    - Empty your trash can (thats what i did)
    -Reboot
    -Install Itunes
    Note: You can Reboot or use Safe Mode to use Unlocker if it doesnt work.
    ....and that's All
    AFTER Days of frustration LOL
    Good vibe, Love and Blessings for all!!

  • HP m6-1225dx downgrade from Windows 8 to 7

    Hi everyone,
    I just purchased a ENVY m6-1225dx that came with Win8 and I'm trying to downgrade to Win7 but not having any success. I formatted the HDD and doing a clean install. The setup completes almost all the steps successfully but then gives me an error at the end saying "Windows could not complete the installation. To install Windows on this computer, restart the installation". This message is different than one I was getting previously that said something along the lines of Windows could not be installed on this hardware. I called HP and the technician and manager were both no help at all. They didn't even want to answer a single question and straight away told me that I should contact Microsoft because it's not HP's problem. Can anyone please help me resolve this? It will be greatly appreciated!

    You need to change in BIOS, hope the following articles help:

  • Downgrade from Windows 7 to Windows XP at the Lenovo G560

    Hello
    I was wondering if Lenovo offers any suggestion/support on downgrading from windows 7 to windows XP or even if they provide the windows xp software image to install on the G560.
    Or do we have to arrange the windows xp and make the instalation on our own. In this case is there any suggestions like windows xp home or PRO.
    Thanks in advance.
    Joao

    Downgrade to windows xp is available only if you are using the following version of windows 7 : 
    Windows® 7 Professional
    Microsoft® Windows® 7 Ultimate
    You need to contact support to order the downgrade discs 
    Here is the link for support (EMEA)

  • Satellite C650-191 - Downgrade from Windows 7 to XP?

    Can I downgrade to Windows XP from Windows 7 on this model Satellite C650-191?
    many thanks for any help

    Hey,
    Theoretically everything is possible because its your notebook and you can install what you want :)
    Such a direct downgrade from Windows 7 to XP is not possible, therefore you have to do a new clean installation. Downgrade is not supported.
    So you have to remove Windows 7 and then you can install XP.
    I have checked the Toshiba driver download page and it seems your model supports XP. That means are all drivers available:

  • Downgraded from Windows 7 To XP: is eligible for Windows 7?

    Hi,
    X301 in Lenovo Outlet has operation system
    Genuine Windows XP Professional - English (Downgraded from Windows 7 Professional)
    Is it eligible for upgrade to Windows 7 back? I'm interesting in 64-bit version.
    Thanks,
    Andrei.

    Yes, it does.  In theory you're buying Windows Seven, which included the right to downgrade to Windows XP.  Lenovo has conviently done this already.  If you can find a Windows disc, the key on your machine should work to install Windows Seven.  Good Luck.

  • T430 - Trouble to downgrade from Windows 8x64 to Windows 7x64 Ultimate

    Hi,
    Just bought a brand new T430, the model number is LENOVO 2342CTO and the BIOS is G1ET73WW.  I'm trying to downgrade from  Windows 8x64 to Windows 7x64 Ultimate.  I first disabled the "OS Optimized" option then I pressed the F9 key to load default configuration in BIOS.  The Secure Boot is disabled, the UEFI/Legacy Boot is set to "both."  During the installation, the laptop restarted several times but the installation process was always able to continue.  After Windows 7x64 ultimate completes the installation, W7 restarts my laptop.  When the laptop restarts up, I see the Lenovo Logo and then the laptop restarts again.  I am able to install Windows XPx64 and run it fine though.  What's going on here?  Any ideas?
    Thanks!

    That seems to be an advanced format drive (4k bytes per sector).
    If you are installing from a Win 7 DVD, it will say SP1 (service pack 1) on the label.  If it's a downloaded ISO, it will depend on where you got it.
    I'm not at all sure that non-SP1 vs. advanced format is the problem here.  It's just something to check.
    You can download a Win 7 ISO that's SP1.  Google "legal windows 7 download notebook review:"
    Again, I'm not saying this is the problem, but lacking another answer, may be worth a try.

    Some games I have will not work on Windows 8.1 and still not comforatble with format.  Have Windows 7 at work.  How can I downgrade to Windows 7?

    Hello @JEH-17703,
    Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
    I understand that you are looking to downgrade from Windows 8.1 to Windows 7, and I would be happy to help you!
    To better assist you, I would encourage you to post your product number for your computer. Below is a is an HP Support document that will demonstrate how to find your computer's product number. Since a downgrade involves the complete removal of your present OS, and the installation of another, It is also important to note that there is no guarantee if your computer will support Windows 7 as a compatible operating system. 
    How Do I Find My Model Number or Product Number?
    Please re-post with the necessary information, this way I will be able to research this further for you. I look forward to your reply!

    How do I change platform for downloading and installing Photoshop Elements from Windows to Mac?

    As long as your license supports both platforms you should only have to download the Mac version and install/activate using your serial number.  If you need help finding a link to download the file, please indicate the PSE version you need.

  • Saving data when downgrade from windows 8 consumer preview

    Can anyone walk me through the process of downgrading back to windows 7 from windows 8 cons preview? from what i understand my personal files will be protected, is there anyway to put my programs on a recovery disc?

    Hi,
    Please check this. The recommendation is to run it one a different machine (I bought one secondhand laptop just for this) or run it under VMWare (I've done this too).
      http://www.forumswindows8.com/general-discussion/revert-back-windows-7-a-5358.htm
    I would not bother to try W8 preview now becaause it will only last for few months. You should try it from late 2011.
