I have Ubuntu 18 installed on my laptop's SSD and I would like to install Windows 10 in a partition that I've made on the HDD drive.

I haven't started because I have some doubts related with the GRUB. Is it completely safe to install Windows after Ubuntu is already installed? Will I have to do something (GRUB re-installation or mount related things) even when I'm installing Windows on a different hard drive?

I need to keep all my Ubuntu files and software as it is my main OS and I will only use Windows to play some games.

I know there are several similar threads but none of them solves this particular issue, in my opinion.

Thanks in advance!

I had the same problem on my computer a few months ago. Since you are installing Windows on a different partition, then all data of your Ubuntu will be safe.

However, Windows doesn't like to live together with other operating systems. Therefore, it will remove the GRUB from your machine, and you will need to reinstall it. The links below present strategies to recover your GRUB.
