    Dual Boot Windows question.

    here is a guide that should do the trick: How to Dual-Boot Windows 10 with Windows 7 or 8

    Just remember if u want UEFI on Windows 10 u most have UEFI on your Windows 7 too if not u need to go change it in the bios everytime u want to go back to Windows 7.

    Changing IDE to AHCI Mode

    Hi guys, I thought i might put this up for people that also might have missed this setting to get AHCI mode working on your motherboard.

    A mate of mine decided to look into it and found a Windows Vista/7 fix so you can enable AHCI mode in your BIOS without the system blue screening, like it does for most computers that are already set on IDE mode.

    Now most of you guys might already knows this but I didn't and all my computers where set on IDE mode and when I would change it to AHCI it would just crash when booting so I just thought oh well it don't work and never bothered with it again. But it seems if you set AHCI mode BEFORE installing Windows you wont have this issue, but if you did not set it before then running this Fix will fix your problem *Smile Changing HDD access from IDE to AHCI under a dual boot system (window 7 & Window 10) :)

    Ok run this Fix > http://support.microsoft.com/kb/922976 then go to your BIOS, change your settings from IDE mode to AHCI mode, save and exit, boot into Windows, it will then install all the drivers that you need for this Mode. Once its finished it will ask you to reboot, reboot and your done *Smile Changing HDD access from IDE to AHCI under a dual boot system (window 7 & Window 10) :)

    Made a big difference for me in boot times and file transfer times, everything sped up alot.

    AHCI vs regular Native IDE


    If you want to change IDE to AHCI in windows 10, without a clean install, do the following steps:

    • Open Command Prompt (Admin)
    • type: bcdedit /set {current} safeboot minimal
    • Restart PC and go into you BIOS -> Set IDE to AHCI
    • Windows 10 will start if Safe Mode
    • Open Command Prompt (Admin)
    • type: bcdedit /deletevalue {current} safeboot
    • Restart and Windows 10 should load with AHCI enabled now

    Until now, I had a 100% succes rate with this, but in the case Windows 10 wouldn't start, go back into your BIOS and set AHCI to IDE.
