How to load a previous operating system

I have a Mac Mini - Intel Core i5 at 2.3 GHz.  He has been under OS X 10.7.5 (Lion).  I've updated to El Capitan.

One of the programs that I have TO use anything beyond 10.8.5 is unusable.

How can I go back to a previous version of Mac OS X?

    Contact your computer manufacturer and ask them to send a recovery disk/s Vista set.

    Normally, they do this for a cost of $ small.

    Or borrow a good Microsoft Vista DVD (not Dell, HP, etc).
    A good Vista DVD contains all versions of Vista.
    The product key determines which version of Vista is installed.

    There are 2 disks of Vista: one for 32-bit operating system, and one for 64-bit operating system.

    If install a cleaning is required with a good DVD of Vista (not HP, Dell recovery disks):

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu

  • Want to download 10 W but not able to do that, during installation, a problem arises and the previous operating system is restored.

    My laptop is preinstalled with Windows 7 Home Basic.  At the free launch Windows 10 I downloaded the same and after 2 months, the hard drive crashed.  The repair shop trying to fix formatting, but could not revive.  This is why I bought a new hard drive and repair charge shot Windows 7 Ultimate edition.

    Now, I want to download 10 W but not able to do that, during installation, a problem arises and the previous operating system has been restored.  When I posted the question about how to solve this problem, I was told to try the download by way of USB/ISO file.

    Now my question is that

    one) can I reload Windows 7 Home basic as I have the product key?

    (b) I can then download Windows 10 according to the normal procedure?

    I'm not tech savvy, afraid to download files in USB and then load into the laptop, so this question.

    Original title: Windows 7 Home basic

    You can directly download Windows 10. Windows 7 complete edition currently installed is not genuine.

    When you upgraded from a previous version of Windows, what happened is that (your PC) hardware will get a digital right, a unique signature of the computer which is stored on the Microsoft Activation servers. The real Windows 7 or Windows 8 license you were using previously will be exchanged with a key to the diagnosis.

    Whenever you need to reinstall Windows 10 on this machine, go just to reinstall Windows 10. It automatically reactivates.

    Therefore, there is no need to know or get a product key, if you must reinstall Windows 10, you can use your Windows 7 or Windows 8 product key or use the reset function in Windows 10.

  • How can I get my operating system restored?

    My laptop (64 bit) crashed while trying to install Windows 10 of a download.

    I thought that Norton had the necessary backup to restore.  Not true!

    Now, no operating system is recognized.

    Do anyone know how I can restore the original Windows 7 Home Premium because it was already on the laptop when buying?

    Thank you

    http://Windows.Microsoft.com/en-AU/Windows-10/Windows-10-recovery-options

    Your laptop came with a partition recovery or recovery discs? If your laptop did not come with recovery discs, you created a disaster recovery support when you got the laptop?

    If not, have you contacted the manufacturer of your laptop to get recovery media to restore your computer to the previous operating system?

    Otherwise you can reinstall Windows (clean) 10

    If this does not work, you can use the same installation media to reinstall Windows (also called a new installation of Windows) 10.

    Original title: someone help please?

    Working on my old computer, a pentium 4, card mother GA81PE1000, I continued to have this message flashing on the screen "ERROR of LOADING of THE OPERATING SYSTEM" after the restart when loading the software Window XP. After so many years, working on the construction of computer & repair, it's new to me.

    So I checked the Microsoft Website for answers from people with the same problem in the past and apply their suggestions, nothing works... hard drive replaced, the changed value in the bios, did everything possible, still nothing works, phenomenal for me, please help me find an answer, thank you?

    Hello

    1. have you made changes on the computer before this problem?
    2 - what you want to say that you receive this error message during the installation of Windows XP?

    Check to see if the following is useful.

    Method 1: Disconnect all devices non-essential connected to the computer and restart. Check to see if it boots normally.

    Method 2: You may need to check the settings of the BIOS (Basic Input\Output System). Check if the hard drive is detected. If this is not the case, check the physical connections. Refer to the manual to check the same.

    Warning of the BIOS:

    BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

    My computer a gateway 815GM Media center PC has become black and start with some gray characters and words back up your data and replace the hard drive is bad. (or similar) My question is how can I move the operating system Windows XP Media Center Edition 2005 to a new hard drive.  Since the problem is the hard drive and all the computer a new operating system should not be purchased.  If there is no way to move it is it possible Microsoft send a replacement free of charge, or at least OS with only shipping.  My computer came with it pre-installed, and I have not received the drive with the OS on it.  What can I do?  Thank you for your information.

    When you received your entry door, it came with a CD or operating system recovery disc. If you no longer have that (or has not made a recovery disc set a utility included), contact Gateway to buy a set of recovery disks. It is normally fairly cheap. Then install the new hard drive and booting with the recovery disk to restore your computer to the factory State. MS - MVP - Elephant Boy computers - don't panic!

    Here's a cool way, go to this site and it will just detect it and say you:

    But another way is to press on +R on the keyboard, and run the winver command
    When you run it, it will appear a dialog box with your Version of Windows is displayed.

    For a little more detail and modern way, hold and press "Pause/break" of the keyboard.  It will appear a box of more modern.  It's also funny that pressing +Break is the trick to show this :)

    Download a program like TreeSize Free (http://www.jam-software.com/treesize_free/) to see where the files take up a lot of space.  Be aware that deleting files without knowing what you're doing can cause your system to be unable to restart or cause instability can so be sure you know that you are deleting before you start.  There is no way to extend one hard disk other than to replace it, in which case you need to copy all the files from your old drive to the new.
