Hi,

My AIO started having issues starting up about 2 weeks ago. I would get a support assist page running some tests and then come back stating that a booting drive was not found. I tried changing several BIOS settings after watching endless videos, but I never got it to work. What I did notice though, is that even though my AIO has two HD installed, one HD and one SSD (Windows is installed in the SSD), my BIOS wouldn't show the SSD. I also tried F12 to look for the SSD as a bootable drive and it didn't show up. 

I ran the diagnostics and it came back OK. All systems were working well. What is interesting is that after several restarts, I was ultimately able to log in. Not sure what happened, but the computer will boot correctly and I would be able to access Windows. Yesterday I decided to download the latest Windows updates as well as run all the tests from Support Dell and again everything came back as working properly.

Today, once again, it is not working. I tried changing several settings and I now get the "Boot failure on device" message. Again, it makes me think the computer is trying to boot from the HD and not the SSD, but I do not know how to fix this.

Please help, I cannot access my computer
