[SOLVED] I installed RAM and now Windows 11 won't boot.

[TheBigSmuz]

I have an Acer Nitro N50-600-eb18 desktop. Stock specs, except that today I installed more RAM, which I verified is 100% compatible with my system (even listed as such by the manufacturer). However, now I cannot boot up Windows. I tried removing the new RAM, just putting it back the way it was, but the issue persists. I get the error message:

"Reboot and Select proper Boot Device
or Insert Boot Media in selected device and press a key"

In BIOS, I can see that my new RAM is recognised. I can see my HDD and my SSD. I can see that everything SHOULD work... but it doesn't. And I can't access the Boot menu.

I tried creating a bootable USB to repair Windows with my laptop, but it can not repair or even find Windows on my desktop. I have also tried a hard reset of my CMOS. Inside my casing, all connections are tight and free of corrosion, and nothing is unplugged.

Anyone have any ideas? Let me know. Thanks!

system memory would normally have nothing to do with drive detection or initialization.
but Windows 11 adds all types of new complications due to it's unfinished development.

my first recommendation would be to do a total drive wipe and fresh installation of the latest Windows 11 install package MS has to offer.

Also when installing the ram make sure you didn’t disconnect anything else accidentally
