It is necessary to install several operating systems on one machine. In particular, Win 7, 8.1 and 10. As well as Linux distributions Ubuntu 16.04.1 and CentOS 7.
Tell me, is the installation order important? If so, which one. And what nuances need to be considered besides this?

Order is very important
Windows uses the MBR, while Linux uses GRUB.
Installing MBR on top of GRUB overwrites the latter. But GRUB knows how to work with MBR, so they put the last
7 (MBR) -> 8.1 (MBR) -> 10 (MBR) -> ubuntu (GRUB) -> centos (GRUB)

Windows first, then Linux. Linux installers see other operating systems on the computer and configure GRUB to load them, and Windows overwrites other people's bootloaders in the MBR.
But it's wiser to put Ubuntu GNU/Linux as the main system, and breed the zoo in virtual machines (kvm and virt-manager will help you).
