Weird Windows booting Problem

[Arttekeov]

I just changed my motherboard from a Gigabyte AB350m-Gaming 3 to a B450 Aorus M.

I have a 500GB NVMe ssd, a 2TB SATA SSD and a 1TB HDD. Windows is on the 500GB NVMe ssd, games on the 2TB and misc. storage on the 1TB.

When I replaced the motherboard I only had the NVMe ssd connected and the other drives disconnected and I was able to boot into windows perfectly, so I then shut down and turned he PSU off to plug in the other drives but this caused Windows to not be recognised and is asking me to restart with a boot media. I turned the PC off, unplugged the other drives and turned it back on and it still comes up with the same message.

I then updated the BIOS to F32 with just the OS drive (NVMe) and I was able to boot into Windows, so I tried plugging the other drives in and now I am back in the same "Please insert boot media" message.

I have made sure the boot order only has the OS drive when all 3 drives are connected. I have tried to boot override the OS drive but this did not work either.

I am really hoping that I don't have to reinstall Windows.

Check your MOBO manual.  Having an M2 port populated tends to disable 2 of your regular SATA ports.  The manual should tell you which ones.  Plug your drives into the other ports and it might solve your problem.

Thanks for the quick response.

 

I just checked the manual and it says only the ASATA ports are disabled with an x4 ssd but I have the other drives in SATA 0 and 1.

I have no idea why this fixed it but I left all 3 drives connected and reinstalled the F32 bios and I was able to boot into windows.

 

If anyone has any idea why this worked please let me know because I am really confused and I think this would be helpful in the future.

Turns out this did not fix it. As soon as i restarted the PC it went into the same "please insert boot media" message

Do any of these steps help?

No luck with these steps sadly. I think a reinstall is the most likely to fix it but I was really hoping to avoid that because it takes so long to get all of the software back on and to relink my games files

That's true, but you aren't playing anything if you can't boot.

Very true. When I get back from work I'll be reinstalling windows then.

 

I'll probably try and reinstall the bios so I can get that temporary boot up to get a list of stuff ill need to re-download then.

 

Thank you for your time

I fixed it now.

It turns out Windows didn't like the version of the bios I was on. I updated to f42a, then back to f32 and then to f42a again and so far I have been able to boot into windows 3 times
