Bios cannot find OS

[Madoggy]

I have just been on vacation for 10 days, before i went away i turned of the power for my PC. 

 

When i came home i tried to start it and it was not able to fin my OS, it had also changed my Boot Device Priority.

So i changed it back to normal, and i tried to start it again. This time it would not Boot as it was not able to find a proper Bood device.

Even thou i changed it back to my SSD that was supposed to have my OS on it. 

 

I know that there are people on these forum that are way more tech savy than i am, and i would like to know if any one of you had any idea to what might be the problem??

 

In advance thank you!

Two issues, the BIOS probably reset after power loss because the CMOS battery on the motherboard must have gone bad. If the system refuses to see an OS on your SSD...I wonder if the capacitor inside the SSD got depleted and the OS was wiped out of NVRAM. If this is the case then you have to reinstall the OS and don't unplug or hit the power switch on the PSU the next time you go on vacation.
