    How to Dual Boot Windows 7 and 8.1


    Hello all, I just recently got my computer running Windows 8.1 and plan to use it as my everyday operating system ,but I was wanting to put Windows 7 on a separate partition because I still want to use 7 to watch DVD movies and maybe still do just a little bit of browsing on the web, nothing to much and I want to dual boot the 2, any help or advice would be greatly appreciated thanks

    I did figure out how to dual boot it, but didn't like the fact that it made Windows 8.1 load up slower than what it normally does and I hate having to switch between operating systems, just to get certain drivers off Windows 8.1 such as the Wi-Fi Driver, so I deleted the partition and made Windows 8.1 the only operating system installed once again and as far as watching DVD's on Windows 8.1, I will just use VLC Media Player, not unless you have another suggested app thanks again

    Windows 8 & Windows 7 Dual Boot


    I have a dual boot system in my laptop and desktop. And I have painfully discovered the same thing, whereas when switching from windows 8 to Windows 7, it has to boot twice making the wait almost unbearable. What I discovered was that the windows 8 bootmanager it the cause.
    what you should do is after installing both OS, start the Windows 7, then go to msconfig and select BOOT tab and set windows 7 as the default operating system, which will make it use the windows 7 boot loader which is a TEXT menu of OS selection instead of the GUI menu which is sooo sloooow....
    Night and day difference!!

    If you still get the slow GUI, then also change the default OS inside the windows 8 to Windows 7 in the msconfig boot option.

    You will still have access to both systems..

    I personally preferr Kodi(formally XBMC) as my all round media player. It works somewhat like Windows Media Center.

    You should install windows 7 in the other drive not in windows 8 drive .If your RAM and motherboard is not too good two operating system can make your comp slow .

    I discovered out something else with Dual Boot this morning, if I were to shut my laptop completely down using Windows 8.1 and turned it on the next morning it would boot directly to Windows 8.1 and not even give me the option to boot into 7, but after I discovered this I all of a sudden started having issues with 7 because after trying to install updates and then restarting my computer to apply them I would get as far as choosing my operating system and the splash screen and get the BSOD and then it would restart and give me my Operating Systems and if I chose 7 the same thing would happen again until I finally decided to boot into recovery mode, Windows 8.1 however is not affected by this error and after I had enough of it, I finally decided to delete Windows 7 and start over from the beginning and so far things seem to be going well, I think what was causing the issue was a driver that I had installed from my PC manufacturer and didn't install it this time.

    All of this has to do with fast startup and the legacy bootmanager. You need to go into a command prompt (administrator) (Win+X, click Command Prompt (Administrator)) and run the following commands, under Windows 8.1:

    powercfg -h off

    followed by

    bcdedit /set {default} bootmenupolicy legacy
