Is the ISO for v2.0.1 supposed to work? I have tried installing with the
directions attached, used rufus to burn the validated iso to a usb stick,
basically picked all the defaults (erased old disk) on an i5 nuc. When the
install completes and the system reboots, I am left at the grub
bootloader. I try to boot and it says there is no loaded kernel. The live
boot works, but if I install through that process, I can't boot up either.
When installing, I get erros that
/usr/lib/lv2/gx_colwah/.lv2/manifest.something... file is not there.
I am trying to install on an intel nuc. Not sure how to get much more
vanilla when it comes to hardware.
Also, I have another nuc that I installed Ubuntu Studio and then installed Jamulus on so I know a nuc can support the OS and Jamulus. I am currently using that system as my Jamulus Server. I am interested in trying JamulusOS to see if there are any optimizations that may help. Every ms counts and I figured it was worth a try.
Thanks for any help anyone can provide.

I guess I will answer my own question. With the same install USB stick, I was able to install Jamulus OS on a laptop just fine. It appears there is something wrong with the Jamulus OS installer specific to Intel nuc boxes. Like I said, I can install Ubuntu Studio just fine on the nuc, just not Jamulus OS.

This installation problem frequently occurs with UEFI-Bios and is probably caused by a mismatch between the directory name created on intalled OS (/boot/grub/efi/EFI/jamulus) and the one expected by grub (/boot/grub/efi/EFI/ubuntu).
A solution that worked for me in several cases is to boot manually into the installed system (see below) on the grub prompt and then copying /boot/grub/efi/EFI/jamulus to /boot/grub/efi/EFI/ubuntu
You found the root partition (for example: (hd1,gpt2)) if the output of this command contains:
/root /boot /etc /home ......
3) Enter using the found root partition (below with the example (hd1,gpt2):
grub> set prefix=(hd1,gpt2)/boot/grub
grub> set root=(hd1,gpt2)
grub> insmod linux
grub> insmod normal
grub> normal
4) After this last command your installed system should boot.
If it doesn't and the grub prompt shows up again, you made something wrong or have another problem.
5) Open a terminal
7) Enter the copy command: sudo cp -r ..... (see above)
Now the automatic booting of your system should work.
Good luck!

Thanks for your help, Karl. I was able to get it to boot using your commands above. (I had previously had to use a "super grub" usb stick to get it to boot.)
However, my install was on a Lenovo FLEX 3 laptop that was set to UEFI-Bios, and I had to do the following copy (based on your suggestion):
cp -r /boot/efi/EFI/Jamulus /boot/efi/EFI/Ubuntu
Thanks, again!

Now I have another laptop where I installed Windows 10 on part of the SSD, and then Jamulus OS on the rest of the SSD, and I get the usual GRUB prompt instead of a boot, and your instructions of how to boot to UBUNTU work, but there is no /BOOT/GRUB/efi/EFI folder, nor a /BOOT/efi/EFI folder, so I have nothing to copy from and nowhere to copy it to.
In addition, now I cannot boot the Windows 10 that is also installed on this PC.

How to manually boot into the installed system on grub prompt:
1) list partitions
grub> ls
gives output like: (hd0) (hd0,gpt1) (hd0,gpt2) (hd1) (hd1,gpt1) ....
2) search for the partition containing the root
for all partitions found (hdx, gpty) enter:
grub> ls (hdx,gpty)/
You found the root partition (for example: (hd1,gpt2)) if the output of this command contains:
/root /boot /etc /home ......
3) Enter using the found root partition (below with the example (hd1,gpt2):
grub> set prefix=(hd1,gpt2)/boot/grub
grub> set root=(hd1,gpt2)
grub> insmod linux
grub> insmod normal
grub> normal

You can try boot-repair:
You may install it and run it by using following commands:
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
At least you should get back access to your Windows 10 by this
Alternatively you can try the rescue USB stick :
