  1. Upgrading from Win7 to Win10 - on a dual-boot laptop


    This is probably an unfair question to ask in this forum. But given the depth of expertise, someone might have advice to offer! I have recently done successful clean installs and activations of Win 10 with the help of Shawn Brink's tutorials and advice from other forum members. I also have a laptop which has Win 7 Pro installed, along with Linux Mint in a dual boot setup. Both in Legacy/BIOS mode. I am using what seems to be a less-typical option for dual-booting. The normal [Linux] approach is to have the Linux bootloader "GRUB" take over from, and replace, the Windows boot manager in the MBR, and boot either OS. The hazard with this is that any Windows upgrade which affects the Windows boot manager will fail, and perhaps also affect the GRUB - potentially rendering both systems unbootable. But there is another way. A clever program called EasyBCD can be installed in Windows. It modifies the Windows bootloader so that it can "see" the Linux OS on a separate partition and offer the option to boot into it. It works well. I would now like to upgrade the Win7 to Win10. In theory, it seems that I can do an in-place upgrade (I've read the tutorial...). This is supposed to preserve all existing files, apps and settings in Win7 and move them onward to the Win 10 install. The main exception seems to be third-party AV programs, which need to be removed from Win7 and then reinstalled in Win10 after the upgrade. Now here is my question. Will an in-place upgrade of Win 7 keep, and transfer, my EasyBCD program and settings - and the changes it has made to the Windows bootloader to enable dual boot with Linux - to Win 10? The simple answer may be I won't know till I try, and the upgrade process will, or should, alert me - before it runs - if EasyBCD (like AV programs) won't play nicely. But I'd be curious to know if anyone else who dual-boots in this way has successfully run the Win7 to Win10 upgrade. I have posted in the EasyBCD forum as well, but it's not very busy.....

    Dual Boot Upgrade Q: Win7 and Win10 Preview

    I currently have a dual boot with Win7 Pro and Win10 Preview. Now, as I understand, to keep both win7 and Win10, I need to purchase a new license for Win10 as the separate partition installation is not eligible for free upgrade program.

    So, I'm planning to upgrade my Win7 itself. Does anyone try this? I'm not sure how it is going to work after the upgrade? Am I going to have Win10 (New, Release version) and Win10 Preview?

    If thats the case, how can I remove the Win10 preview installation? It doesnt make any sense to have the Preview version if I have the Release version on the other boot

    Thanks in advance..

    WIN10 /WIN7 Dual boot, WIN7 forced to upgrade to win10, now I can only boot to Primary WIN10 drive

    I have a WIN10 install on a 256 SSD (DRIVE 2)

    and had a win7 install on a 1tb WD Black HD (DRIVE 5)

    My primary boot was WIN10 (D2) and always had the option of picking wich drive to boot to on start up.

    I was recently forced to upgrade my WIN7 (D5) to WIN 10. It completed the update and I was using the opperating system on my 1 tb HD and it was working fine. Then I shut off the computer and came back about 4 days later and I couldnt boot to my second
    win10 install. (there may have been an update to the win10 before I shut it down)

    I went into boot up options and selected the 2nd win10(win7) Drive 5 as primary boot and it reverted back to the original win 10(drive 2) boot.

    What is the best way to have a dual boot win10 system and how can I change my boot up options so that I can continue to choose the boot up drive?

    WIthout a doubt the upgrade Win7 drive is still there and can be used, but there must be a boot settings that is preventing it from being accessed.

    If i am not allowed to have a dual boot WIN10/Win10 machine, can I revert back to WIN7 on the upgraded drive?

    Also, original WIN10 install was from a win8 upgrade, 2nd one is from a win7 upgrade, both fully registered versions of WINdows.

    Much apprecaited
