Yes. I gave you the link above but maybe it was hidden in my huge block of text. Sorry about that. Here it is in full The rEFInd Boot Manager: Installing rEFInd
Essentially you mount your EFI partition, copy the rEFInd folder to it, rename refind.conf.sample to refind.conf and then tell your boot manager to load rEFInd not windows boot loader first with (from an elevated Windows command prompt) bcdedit /set {bootmgr} path \EFI\refind\refind_x64.efi . That is it.
You only need to update the refind.conf in very unusual circumstances. Otherwise if you can make new partitions, insert an external USB or SD card with Windows or Linux on it and it will be found and you can boot it. If it isn't there then it will not appear as a choice.
If you are interested in EFI and GPT partitioning the rodsbooks site is the best I've found even if you decide not to install the loader and use something else.
