Uefi boot is missing

I have a dell inspiron 15 3511 laptop bought around 3 years ago. The laptop was working fine till around 2 months ago. It started when I used a lower power adapter by mistake, then I started to have boot problems. I'm not sure if the use of the lower power adapter is the cause of the boot problem.

The following itmes are tried:

1- When turning-on the computer, I have the following message: Install driver to show hardware.

2- When I use the media installation USB, it allow me to start the installation till seaching for the disk to install-on. Only the disk used for the media installation is detected.

3- On the boot configuration (when selecting F12) I can see

a- the UEFI TOSHIBA MQO1ABF050 84RRCQNT (which is the installed SSD SATA drive)

b- UFEI HTTPS BOOT

4- On the storage page, we can see the SATA SSD and the M.2 PCIe SSD. ( I added recently the M.2 hopping to be able to boot the system)

5- I tried to reset the battery and CMOS coin battery, but was not able to find the location of the CMOS battery on this laptor.

I tried many other approaches, but was not able to resolve this problem.

Any help on clarifying how to access the boot system is highly appreciated.

Thanks and Regards,
