BIOS doesn't detect M.2 drive when restarting laptop

I have a Dell Inspiron 3525 with Windows 10 installed on it. BIOS last version available.
If I turn on the PC normally it boots the OS correctly. On the other hand, if I restart the machine then it will not boot properly and I will have the error "No Bootable Device".
I found that when restarting the laptop if I go into the bios the M.2 drive doesn't appear, but if I enter the BIOS just by turning on the PC normally then it shows.
For some reason the drive isn't detected when rebooting the laptop but when booting normally it is detected and it boots correctly.
I have a SATA HDD installed with nothing on it and the BIOS always recognizes, it is empty. I don't think it contributes to the problem but I just wanted to mention it.

BIOS after booting normally, M.2 is showing up there

BIOS after restarting the laptop, M.2 not showing, only "First HDD"


When restarting there are no available Boot options because M.2 is not recognized, so that is why then I have error "No Bootable Device"


I don't know what can I try and why does this happen. Of course I can just avoid restarting my computer but I wanted to fix this issue if possible. Thanks in advance.


Extra: I've also had issues with the sleep functionality, when I wanted to wake up the PC it would crash. Doesn't bother me that much so I disabled sleep.

Update: I now have an M.2 Kingston drive instead of the Gigabyte that I had. Now I'm having no issues. I think it was the drive's fault because I tested it in different computers and the same happened. Hope it helps to someone that is having the same issue, don't go crazy changing settings in the BIOS, just try to get another drive or test the same drive in a different computer and see how it goes.

Was the OS factory installed?  If it's user installed, check the boot drive in Disk Management to see if all boot partitions being installed.  Verify in BIOS settings if SATA operation mode is AHCI and Boot Manager is first boot.

@Chino de Oro​ I installed the OS with media creation tool from a USB drive. SATA operation mode is AHCI (there is no other mode). This computer's BIOS is very basic, I don't have much things to tweak.

The initial guess was the EFI boot partition being installed on the HDD.  But that was not the case, all partitions are on the boot drive.

The next troubleshooting step is boot priority setup.  Many of Dell newer laptop models are specifically set to boot from a primary storage when both M.2 and SATA are being used.  For testing purpose, remove your HDD temporarily to see if that makes any different.  Note that you haven't set partition to the HDD neither.

 I guess that you did not have the problem with the original shipped Win 11 drive?  That would narrow down to storage settings and Windows installation.

Also, edit your post to remove pictures that contained your personal info (system tag) per forum TOS.

@Chino de Oro​ I already did the HDD thing and it didn't impact. I also removed the M.2 and put it into my desktop computer and I had the same issue. When I restart the computer the M.2 doesn't even show in the BIOS. So I think it is an issue with the drive itself. There are no firmware updates available for it so I can't even try that.
I never used the "original" shipped drive cause the people that sold me the computer changed the original drive for this one... I guess tomorrow I'm going to their store and see if I can get the SSD replaced if that's the issue
Thanks for your help!
