[ubuntu_studio] Can't boot to newly installed studio

Hi,

I have a Win 10 PC and have been using a USB stick install of studio but now wanted a full blown studio on an SSD to boot from in a dual boot.

I installed studio on the SSD from the USB stick and it showed it installed correctly but after the reboot it does not boot to it. I have tried with and without the Win 10 primary os disk attached but still no boot to SSD.

I have this image of what is going on and I am not sure why but it shows a drive letter and /target which is where Linux looks to be.

Any ideas what has happened in the install and how to get it back to a good bootable studio, even if I have to do it again.

I see that Win 10 says one can install Linux inside it but not too sure about it, so will go with the separate disk and do a dual boo eventually.

Thanks
