Ubuntu won't install beside Mint

[Remi Marentette]

Tried installing Mint beside Windows at the beginning. Could only access Mint from bios after installation, or Windows, by changing boot order. Tried installing Ubuntu beside Mint to see if that made a difference. Now, when I boot (with f1} I only get boot order Ubuntu and Windows boot manager and neither one boots up, just comes back to the boot order no matter what I so. Booted from Windows recovery usb and just would not recover no matter what option I picked. Figured Windows was toast so formatted any windows partition (From the Ubuntu install disk after loading and trying Ubuntu as the option and going to Disks} and deleted those partitions to turn them into unused space. Rebooted and reloaded Ubuntu install disk and tried an install beside Mint, which still appeared to be there. No dice.Still won't boot unless I hit f1 and then defaults to just the boot order of Ubuntu and Windows boot manager! Would like to just erase my ssd and start with fresh install of Ubuntu but not sure how to accomplish that unless I use my desktop (That has Windows, Mint and Ubuntu running side by side with Grub showing up at boot to give me the option of OS's} I have another ssd plugged into a usb that I could exchange for this ssd in my laptop and do whatever is necessary to it from there. Or I could just download the Windows 10 ISO from the Microsoft website and start over. Not sure if any of those options are the right ones. HELP!
