Satellite C850D - Downgrade from Windows 8

I have a Satellite C850D, which was shipped with Windows 8. I want this downgrade to Windows 7. I have a Windows 7 DVD, but when I try and install it I get is an error message indicating that there is an error with one of the startup files.

Is it possible to install Windows 7 on a computer that came with Windows 8, and how to remove the OEM of Windows 8 version and replace it with Windows 7.

Any help/advice would be appreciated.

Hi Sean

Yes, it is possible to install Windows 7 and other systems. But this requires some changes in the BIOS.
You must disable secure boot and go the CSM UEFI.
As far as I know after changing two options, you should be able to boot from the Windows disc.

  • Satellite L50t - Downgrade from Windows 8.1 for Windows 7

    8.1 Windows was preinstalled on my L50t satellite. Will there be problems if I do a new install of Windows 7 Home Premium?

    Driver Toshiba UE page provides Win 7 64 bit drivers for different satellite series L50T-A so should not be a big operating system Win 7 64 bit on this laptop.

    Even if you get all the Win 7 64 bit drivers, tools and utilities, you should be able to run Windows 7, but of course with limited access to the features of the laptop.

  • Downgrade from Windows 7 to Windows Vista

    Hello

    I want to ask something about the downgrade from Windows 7 to Windows Vista Edition Home Premium!

    My laptop is Satellite L510. When I bought it, it came with Windows Vista Home Premium as its OS so I already created a recovery disk.
    Now, if I update to Windows 7 and if I want to downgrade to window Vista... often I just use this recovery disc to format to Windows Vista everything as before?

    Because they do not have the Windows Vista installation disk when I bought this laptop.
    And I want to ask now the window Vista already got a healthy recovery partition in my right HDdrive? If I update to Windows 7 then did the Window Vista healthy recovery partition is still there, or only the restore disc that I create before you reformat Windows Vista Home Premium box?

    Thanks to all who try to answer my question!

    All new laptops are shipped without DVD upgraders and everyone must create one. This is why Toshiba has designed small Creator called Toshiba Recovery tool. With this tool you can create recovery DVDs and use them for the installation of the OS more far.

    Whenever when you use, you'll have to factory settings and it will be like on the first day when launch you for the first time.

    When you have this recovery media, you can do whatever you want and, of course, install Win7 with HARD drive. One day, when you want to have Vista again just use created recovery DVD and you will have factory again.

    When you bought your laptop recovery image was recorded on the second partition of HARD drive in the folder called HDDRecovery. This image can be used to install Vista with the factory only settings. When you install Win7 these files can no longer be used and Vista must be installed from recovery created DVDs.

  • Can I downgrade from Windows 7 Starter to Windows XP Professional

    QUESTIONS: 1) can I demote a machine Win7 Starter purchased through package of retail full license, never installed, XP Pro OS?  Assume that both are 32-bit.  I was thinking of buying one of these netbooks cheap in Walmart stores that are Windows 7 upgrade option to Windows 8 (which I do not wish to use), and experiment.  If Win7 is proving to be as disastrous as I wait, I want to install a new copy of the new detail of full XP Pro including Service Pack 3 (which has never been installed on any computer), to downgrade from Windows 7. I've never used in triplicate.
    The machine is Acer Aspire One with Windows 7 Starter edition, on sale at Walmart for only $228.  They have other editions of Windows, I could buy instead, if the Starter Edition is not eligible for a downgrade.
    2) do you anticipate problems of license?  Do not talk about compatibility, as that varies depending on the machine.  It's just that the installation with MS products is always also annoying complicated and always associated with a licensing problem.  I can't guess at what these problems are, they are never what I expect.  Where the question.
    Backstory: I am wary of XP Professional updating to Windows 7, due to the many people experience incompatibilities.  I ran the Win7 Upgrade Advisor, and he has not yet detected what third-party software was running on my machine in his analysis, other than common programs of MS and stuff from the internet.  So I have ZERO faith it will be compatible with my XP software current and material, so 32-bit (which I use now), or 64-bit (which one of my machines can take in charge, but instead, 32-bit XP Prof OS is installed and running).
    It cost me about $100K of my time to switch to XP, in 2005; I just went through two own XP installed on two of my other machines.  Recovery was not possible.  Cost me three months of my life, these facilities.  Wouldn't do it again.  It is unnecessarily complex.
    So I have to check the effectiveness of Win7.  And if she is not enough justify using, as I hope - I have a lot of detail that new (well, once again) never used XP Professional OS bought in a store, that I can use to downgrade.  ("not OEM, not upgrade or academic, etc. so the full XP license is valid for each packet.)  I understand very well that support ends in April 2014 and don't care if it stops.  What I care about is running my business that threatens to Win7, because it changes the interface and eliminates a bunch of features that have been very productive in XP Pro.
    Of course, my impressions have not been tested on a live installation.  ERGO this post.  For me, it's a $100,000 decision, because it is the cost of my time if I deploy Win7.  Sorry for ranting, but I need to explain the reasons for downgrading in context.  Thank you for your time!

    I guess I do not understand you. If you have a version of Xp retail packaging, you can install it on any computer you want. Nothing MS or anyone else can say about it.

    As others have noted you might encounter a driver for some of your hardware problem is not not compatible wth Xp. The only way to know for sure, or I should say the best way, is to install Xp and discover.

    If it was me I would make sure that the computer has a restore disk or a partition to reinstall Win 7 if Xp didn't work. If none of those who were present I would clone the drive hard while Win 7 was still about this. Better safe than sorry.

    Finally, I would make sure that I got a usb Ethernet card so that you could make sure you have the ability to connect when the net card driver was not installed with Xp...

  • How can I downgrade from Windows 7 to Windows XP? Where can I get the disks for this?

    No not supplied with the PC recovery CD.  Where to get recovery HP CDs. says buy from Microsoft, Microsoft says contact manufacturer

    original title: Downgrade from windows 7 to XP

    If you have an HP computer with Windows 7 pre-installed,

    (a) you will not be able to find the drivers for your computer hardware for XP (except if you bought your computer, just like Windows 7 was spilled) - even if you could find somehow a copy of XP to install and

    (b) any person at HP who told you to contact Microsoft won't - HP is obliged by its license from Microsoft to provide you with a mechanism (it doesn't have to be physical CDs) to reinstall the operating system that was on the computer when you bought it.

    Hello

    To install windows XP on windows 7, you need to start your computer while the cd is in the drive. This will allow the system prompts you to "Press any key to boot from the CD-ROM.." and then follow the instructions accordingly.

    If computers were purchased with Microsoft's Downgrade rights, they would be shipped with Windows 7 Pro 64 bit installed in the factory and restore HP 8/8.1 Pro 64-bit Windows included media.
