I have looked at several forums, but I have had trouble figuring out the right steps to fix the issue. I updated grub and it will not see the os on my ssd. OS-prober does not return any values. I assume that it only searches the drive that it is intalled on. I used boot-repair to no avail, except for this handy link with a lot of system info. https://paste.ubuntu.com/p/QzzKhGYm4v/ I have Ubuntu running on one HD and windows 10 on a separate drive. The windows 10 install is on this drive /dev/nvme0n1. boot-repair says I can use gparted to make a boot partition, but I am reluctant to do so without guidance from the community. I have messed this process up in the past. The BIOS does not give me an option to boot into my other drive either. I installed grub customizer and I when I make a new entry for the windows disk using chainloader, the program tells me there is an error building boot sequence. Check parameters! If I need to share more information I can. Can I make an entry into the grub config file that will allow me to boot the os on the nvme0n1 drive? Do I need grub installed on that drive? nvme0n1p1: _____________________________________________________________________

GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again. Alternatively, you can retry after activating the [Separate /boot/efi partition:] option.
