    This is highly annoying, I dual boot between win 7 & win 10, and when I pick win 7, all is fine it continues to load the OS.
    However, when I pick win 10, it resets the machine, and then loads win 10.

    I am trying to figure out why it resets the machine just so it can launch win 10?

    Anyone know the reason behind this?

    I've been wondering this too. Would this have anything to do with Secure Boot or UEFI?

    The machine I am using don't have secure boot or a UEFI BIOS... so, don't think that is the case.

    For what it is worth, if I replace the MS boot loader with GRUB, then, it don't reboot, it just boots directly into win 10.

    Maybe because it's switching from MBR to GPT?

    Different boot manager gui.
    W7 has the old one & W10 has the new one that came out w/ W8.

    Same thing happens to me, I have W10 as my default OS but when I choose W7 from the (new gui) boot manager the PC restarts & boots into W7 automatically & bypasses the boot manager.
    When I set W7 as the default OS then when choosing W10/W8.1 (in the old boot manager) the PC restarts, same as yours is doing & boots directly into the W10/W8.1 OS I chose.

    This is because with Windows 10, the system pre-loads several operating system files before presenting you with the choice of os menu. If you choose Windows 10 in the menu, booting continues with the remaining system files, giving the impression of a very fast boot time. But if you choose a different os, then all those preloaded files are useless, and the system has to reboot the computer to restart the booting process for the other os.

    In a command window running as an administrator, type the following command:

    bcdedit /set {default} bootmenupolicy Legacy

    Next time you boot you will be presented with the classic text mode boot menu of previous Windows versions.

    One of the reasons I uninstalled Win 10 and said goodbye.
    laqk's fix may solve the problem, but I'm not going to test it

    lark's fix SOLVES the problem.

    It's the first thing one must learn since the day that Win8 released, and looks like a really minor problem to me. Blame the things that hasn't a solution, not the ones with a supersimple one

    There are many things I do with Windows 10 after a clean install. So many that I have a portable folder which contains a cmd file that I run as administrator. This takes care of 99% of all my customizations, and even program installs. There has not been much I have NOT been able to do with Windows 10. There are many excellent coders that have solved all sorts of issues, and I take these solutions, and adapt them to what I want. I have never found a reason not to stick with Windows 10. It is all about perseverance, failure, reinstalls, and hopefully, eventual success.

    Diversity opens minds. Yoma like the American food, but there isn't any reason to not taste spaghetti, lasagne or sushi.

    Nowadays each OS can do mostly most of you need even Macos or Ios :)D) but dealing with different OSes makes the user flexible, wide minded.

    That is, It's like traveling, learning different languages, facing different cultures

    No need to switch, nor to stick to windows and/or to anything else, just try and use what's available, sometimes.

    Code:
    bcdedit /set {default} bootmenupolicy standard
    --
    When I was dualbooting 8.1 and 10, I just switched the default OS in msconfig to the one I was about to boot into, before I rebooted, and it used that OSs bootloader, preventing the double reboot, when I wanted to go back to the other OS, I set it as default first, then rebooted

    Legacy menu is not good just to switch quickly, but also to get out of troubles using the safe mode or to disable the driver signature.

    Unless you have a keyboard less device there isn't a single valid reason to keep the ugly new thing

    Yea I agree, I just hadn't bothered changing it while I was DBing, I usually set to legacy straight away for safemode reasons

    People who find hard to remember the syntax, or scared by the command prompt, or just too lazy to do it, can use easybcd to get the same effect. Just uncheck "use metro bootloader" and save the settings.

    I was wondering how many posts it would take before someone mentions EasyBCD from neosmart.net.
    I use it to boot directly into VHDX drives without having to use Hyper-V.
    It's a great little application. Also iReboot is a good partner with EasyBCD, so when you want to reboot into another OS, you select it from iReboot and when your system reboots it boots into that selected OS directly.

    I stared using VHDs even for main installations.

    Too handy to not use them.

    VHDs are very handy, and you do not even need a main OS to use them. You can have your disk with only VHDs. Backing up is as easy as copying a file! The only thing you can not do with a VHD is update from one Windows build to another asfaik!

    I used to work only with VHDs. Main system, test systems, etc. Like other users said, way too useful not to use them. I even dual booted with Linux Mint using mint4win. But when I started triple booting with OS X I couldn't find a solution for booting OS X from a dmg, so I was forced to use at least one separate partition. Then I said to myself if forced to use partitions, might as well use them also for my other systems. :pardon:

    Turn of fast boot if it is enabled, this can cause problems.
