If you’re using UEFI there is nothing to reinstall. The installed bootloaders are still there in the UEFI partition, Windows just changed which one is set as the default. There are tools you can use, such as EasyUEFI (if I remember correctly), to revert the default to Grub or refind or systemd-boot, whichever you’re using.
I’m not sure, to be truthful. Never looked into it! But even if one exists, I’m sure what Windows is doing during an update is grabbing its own bootloader and either installing it or just hitting the switch to set it as the default bootloader.
I say all that to say, that even if there is a grub made specifically for windows, it likely wouldn’t fix this problem. To ultimately get around this, a user would have to change the features in the Windows update, which I believe is possible since I know some installations exist that remove features from Windows during an initial OS install.
But I do believe that Windows’ default bootloader can boot into a Linux OS too. It’s been a while, but I have seen where you can choose different versions of Windows if you have them installed dual boot on the same machine. Where the bootloader will ask whether you want Windows 7 or Windows 10 to boot into. I believe Linux OS installs show here too, but I could be wrong. The problem is really that the bootloader doesn’t show by default so the user doesn’t know a second OS exists on the same disk. If Windows’ bootloader showed by default and let you choose your OS to boot into, I don’t think we’d have the issue OP’s meme shows except with it hiding grub or another non-Windows bootloader.
Is there a grub installer that runs under windows? (no spell checker I refuse to capitalize windows)
