I currently have 2 drives: (Primary C: drive and D: HDD drive storage), C: drive is an SSD NVMe and has Windows 10 on it plus the boot loader with Grub for Ubuntu 16.04, Ubuntu 16.04 it's self is installed on the 2nd drive D: HDD. I'm going to be installing Fedora25 on the D: drive with Ubuntu. After spending the last 2 days reading multiple different ways to install Fedora along side Windows and even Fedora\Ubuntu with Windows, I have yet to get a definitive answer to a few of my questions. First, do I need to manually expand the EFI partition on the primary C: drive to achieve the 500mb needed for the Fedora /boot, or will it auto-detect Grub bootloader and automatically configure and add the needed 500mb for Fedora /boot? So I guess what I'm asking is, will Fedora automatically detect Grub and automatically add the needed 500mbs plus add Fedora to the Grub alongside Ubuntu and Windows, or do I need to manually re-partition the EFI partition and add 500mbs worth of space and manually do a mount point for the /boot? Second question, for some reason when I created an "unallocated" partition on the D: HDD of 100GB's, during install, it stated that that was not enough space required for /root, /home/, and swap. Do I really need more than 100GB's for /root, /home, and swap? My D: HDD has around 700+ GB's of free space. My head is pounding from reading so many different posts about all of this and I am just needing some help to be pointed in the right direction. Any help is most appreciated. Thanks, ShaunB.

I do all such installations using the live CD download (in my case then written on a bootable USB) and allow the installer program to select appropriate options. When you get to the screen to configure the installation drives and partitions - early on in the install process - it will allow you to, for example, shrink a partition to create sufficient space to install Fedora.

I've never yet had any problems with dual booting or any other system issues when done this way. I once tried to manually configure the partitioning. Never again ;0)

I've already tried doing it that way but for some reason it won't allow me to do so unless I free up space (which I did). It looks like I'm going to have to extend the EFI system partition manually using gparted or some other application. I don't mind manually doing my own partitions, but based on what I've read, you can't have multiple GRUB2 bootloaders in a EFI partition, so I believe. GRUB2 is already present via Ubuntu, and also has Windows 10 on it as well. I haven't read a clear solution to getting Fedora25 onto an already existing GRUB2 bootloader. a step by step would be helpful.

Sorry it took so long to get back here, was out sick. Well I figured out my issue which was to convert my 2nd hard drive from MBR to GPT. This resolved all my install issues.
