External SSD is in boot menu but won't boot

[dwhail]

Hi,  I set up my NUC 10i5FNH in January. My internal SSD is a Samsung NVMe 500Gb M.2.

I have an external SSD in a caddy with USB lead. I have cloned internal to external drive as a back up. Everything looks fine in disk manager. The drive is an M+B key so I can't test it in the NUC.

The external drive shows up in the boot priority menu  as 'J' drive. 

I set J drive as first in priority but it will not boot. I get a blue screen with a message which says "No accessible boot drive" it restarts automatically and then same again.

I suspect it is a BIOS setting I am missing as the external drive has worked without problem on my old HP Pavilion i3 which I just replaced.

Thanks in anticipation.

Hello dwhail,

Thank you for posting the Intel* Community.

To better assist you, please provide us with the below details:

• Provide us with a picture of your Boot Order.

Also, when booting with the internal driver, provide us with the Intel® System Support Utility (Intel® SSU) 

• Download the Intel SSU https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-
• Open the application and select "Everything" click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View". 
• Click on the menu where it says "Summary" to change to "Detailed View". 
• To save your scan, click on "Next", then "Save". 

Best regards,

Maria R.

Hi Maria R,

I gave up with the external drive and put a smaller SSD in  the SATA 2.5 bay in the base.

My apologies, I should have closed the ticket earlier.
