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.

Anticompetitive behaviour from microsoft??? gasp
No, Windows is just setting the computer up for users who don’t typically change anything in the bootloader.
I can confirm. It does this I think if both OS are on the same disk, probably share bootloader. Never happened when I used separate disks.
Is there a grub installer that runs under windows? (no spell checker I refuse to capitalize windows)
