    Cannot dual boot after installing Windows 10 with Windows 7


    The win7 mentioned is latest since it is auto-updated. win10 is version 1903.

    This is not the first time I am doing this. Months ago I did it on my own PC: old system is win7 with single HDD, I shrink the win7 partition to spare new volume for win10, install win10 with USB media, and I automatically got dual boot after finishing, and using both so far so good. Yesterday I did the same for my friend on his 7-year old laptop (lanovo x230) which is also a win7 on single HDD system. At first, everything went as expected. After it went through the setup with green checks up to FInishing Up, it rebooted and I could see dual boot of win 10 and win7 there. Naturally, I selected win10 for it to continue the installing, then it went through the initial setup, creating first user etc., it reboot again. But this time not dual boot appeared. It went straight into win10. Now I am not able to boot win7 thought win10 seems to work fine.

    Searching the web for solution but all are telling me the same method I did above. None so far on how to create dual boot when you have both OS in place but no dual boot. I did a Code:
    on win 10 and attached below. Hope somebody can tell me what to do next. Thanks in advance.

    Code:
    :)

    What is the best way to set up a dual boot of Windows 7 and 10 after a fresh install of Windows 10

    Windows 7 and 10 hate each other, I had dual boot W7/10 and they just want to repair each other all the time which ends up screwing the install and then refuses to boot. You have to install W7 first I think then Windows 10, you cant do it the other way around. This was on 2 separate HDDs

  4. Cannot dual boot after installing Windows 10 with Windows 7

    Installing Windows 10 using Windows 7 key

    Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

    As for getting rid of Windows, delete the Windows folder.
