There were other bugs on the list that were similar to mine, but they were all trying to install other OS versions. I'm trying to install Ubuntu 20.04 LTS on my machine, and I'm trying to dual boot it with Windows 10. I have already have Win 10 on the same hard drive that I'm trying to put Ubuntu on, it's on an NVME SSD (500 gig model). There are a few interesting things that happen during the installation process that likely help lead to the Ubuntu install crashing before completion. One of them is that when it gets to the install options, there is actually no listing for "Install Ubuntu Alongside Windows". The only options are for "Erase Disk and Install Ubuntu" and "Something Else". So, I click "Something Else". The other interesting thing I've noted is that there is no EFI file detected on my hard drive once you click "Something Else" to manually partition your drive, so I have to make one by selecting EFI partition and giving it 250MB or so. If you try to click the install before you do this, a warning message will pop up that you may ruin the installation, so I always obey the warning. I believe this is part of the problem because it doesn't show to create an EFI file in any of the Ubuntu install guides I've seen, so I strongly believe it leads to the crash.

Once I finish manually partitioning, giving ~20gigs for the "/" directory and the rest of my 200GB partition to my "/home" directory, it goes through the install, and then it eventually crashes at the same part every time.

"Executing 'grub-install/dev/nvme' failed.
"This is a fatal error."

The above is what the error message reads. I've even tried to install Ubuntu again, directly after it failed, with half the Ubuntu install still on the hard drive. Hilariously enough, there came an option for "Install Ubuntu 20.04 alongside Ubuntu 20.04" because it detected the other install. I selected that option, but it still failed at the exact same spot, with the exact same error.

Hope this helps.
