I recently tried to install Ubuntu GNOME 16.04 on a separate partition on a newly built machine. It already has Windows 10 installed in BIOS Support Mode. I made a LiveUSB and tried to run the installer in
legacy mode but it continually craps out on me (black screen with a cursor), so instead I tried running it in
UEFI mode. I know that when dual booting it is best to keep the boot modes the same, but I could not get the Ubuntu installer to run in Legacy mode and I figure I can switch between OSes by setting the CSM settings in my motherboard's BIOS whenever I need to.
The problem comes up when I get to the actual installation phase of the bootloader. After downloading updated files and beginning the setup, I got following error
GRUB installation failed
grub-efi-amd64-signed package failed to install into
/target/. Without the GRUB boot loader, the installed system will not boot." Does this possibly have to do with the fact that I already have an OS installed into BIOS mode? Is there a way to run the installation in Legacy mode without getting a black screen?
Please help me; I am at my wit's end. I have tried everything that the forum Q&A's have suggested and still I cannot get my system to boot properly. If there is anyone on here with experience dual booting Linux, feel free to offer your advice. I am an novice in Linux and have not typically had experience with matters of dual booting.
Thanks in advance.

Also, it should be noted that I get an
unknown chipset nouveau error whenever I launch the
bootloader. I have yet to see an Ubuntu desktop so I wouldn't be surprised if there was a persistent driver problem I have yet to rectify.
