When upgrading to Windows 10, will the MBR be replaced?

[Windows Central Question]

Hello.

I have got one question.

I'm currently using in my computer 2 OS. Windows 8.1 and Linux in separate partitions.

I use both OS but the default bootloader is GRUB, which is installed in the MBR.

I'm looking forward to upgrade from Windows 8.1 to Windows 10, but I'm not certain if this upgrade will replace the MBR. Will it be replaced?

I don't think that it may be a problem but it would be interesting to get more details about this topic.

I don't know for sure, but I my gut tells me this will mess with/overwrite GRUB or whatever boot solution you're using.
