    Does windows 10 nov update work better with Grub2?


    Does windows 10 Nov update work better with Grub2 installed? When the original release came out, it did the upgrade but when almost completed it rolled back. The workaround I did, was to restore windows 7 boot using bootrec /fixboot and bootrec /fixmbr from a windows 7 repair disk. Installed windows 10, let it update, then reboot. I reinstalled grub. Then it was working. My concern is future releases, since they get automatically downloaded.

    By default most Linux distros install its Linux Boot Loader (GRUB) in the Master Boot Record (MBR) of the HD, Basically replacing the Boot loader for Windows, so GRUB handles boot loading for both Windows and Linux.
    Pro: Grub has wider compatibility than Windows Boot loader, it can boot multiple different OS'es from the same HD
    Con: Since GRUB is in the MBR and if anything happens to GRUB, every single OS on the HD becomes unbootable such as in the case of Windows Updates/Service Pack installation which can modify the MBR and override GRUB and now you're back to a single Windows boot even though Linux still exists but there's no way to boot it. On the other hand, if Linux get a kernel patch or update, it can modify/reconfigure GRUB and causes Windows to be unbootable.
    The screen shot shows a normal dual boot configuration in #1. To separate the 2's and put GRUB in its own partition with Linux so that any update in either Windows or Linux won't break anything as shown in #2.

    I have read people had problem booting Linux from the Windows Boot manager using easybcd. The issue maybe because of secure boot-even those distros that support secure boot.


    Would this be the proper way to do it?
    Restore windows 7 using bootrec /bootfix & bootrec /fixmbr
    Upgrade to windows 10 & do needed update if any
    Bootup to your Linux distro (I have a boot disk that can boot directly to my Linux system)
    then grub-install /dev/sda6
    Then reboot into windows and use bcd to boot to grub


    The only issue is how to prevent grub updates from writing to /dev/sda and force then to write to /dev/sda6

    You are running Windows with the Legacy BIOS (MBR) so secure boot is not available. Easy BCD will work with MBR disk type.

    Would this be the proper way to do it?
    Restore windows 7 using bootrec /bootfix & bootrec /fixmbr
    Upgrade to windows 10 & do needed update if any
    Bootup to your Linux distro (I have a boot disk that can boot directly to my Linux system)
    then grub-install /dev/sda6
    Then reboot into windows and use bcd to boot to grub
    Yep, just install GRUB on /dev/sda6

    The only issue is how to prevent grub updates from writing to /dev/sda and force then to write to /dev/sda6
    This is important step, you'd need to re-install Linux then install GRUB on sda6 instead of sda (MBR) so that the 2's are independant from each other then use Easy BCD to add GRUB2 boot loader. Any future update from Linux will not update the MBR.
