I have just fitted a new Gigabyte B560M DS3H (Socket LGA 1200) Micro ATX Motherboard, with a i3-10105 CPU, Crucial Ballistix 16GB (2x8GB) DDR4 RAM and a new power supply Corsair TX550M 550 W 80+ Gold. It all seemed to go well, all connections made etc, right up until I started it, of course.
It does the single beep POST, but only goes into the Gigabyte BIOS, I cannot get it to boot into Win10. The SSD is recognised by the BIOS as you can see from the image, but it won't boot to it. I have tried fiddling with settings, but nothing. Any ideas please?

I cannot remember where it will be but look for a csm/legacy option for the SSD. If it is on csm/legacy change it to the other one and if it is not on it then change to it.
 
Thanks - I did try that earlier I think, but I will go and give it another try. Whatever I did, it didn't even boot into BIOS, just a black screen with a static cursor at the far left.
 
Another thing to try is to just have the one drive installed for the first boot. Disconnect all the drives that do not have the OS on it and try to boot with just the OS drive.

Is really annoying when the software is more troublesome than the hardware.
 
Kind of regretting that I changed the CSM Support settings, because I now cannot get to BIOS at all - it just goes to a black screen with a static cursor left of centre, but no splash screen, so I cannot press DEL for BIOS settings...
I have disconnected the optical drive, still nothing.
 
Well I have never reset CMOS before, so that was new (thanks for the tip) - now back where I was in the 1st post i.e b&ggered
So much for upgrading the wife's PC while she was away for the weekend!
 
That is exactly what I have done. The last time I upgraded this PC with new MB, CPU & RAM (not HDD) I think Windows booted just fine, but not this time. I am about to bite the bullet and reinstall Windows destructively, which was not the plan (though I do have the data, but possibly not the MS Office key).

Won installer is saying that it's MBR and needs to be GPT, so I have to sort that first.

Any help welcome!
 
You are probably right. Funnily enough, I am about to replace the 500GB M.2 in my ThinkPad T490 with a 1TB, so that could work... The PC I broke is my wife's!
If I replace every single component, isn't Win10 going to complain about licensing?
 
when you changed the motherboard you would have already lost the activation for window 10. if it had booted up it would have detected the hardware changed and deactivated. However from memory when you try and activate and it fails i think there is option to look at what devices you already have activated and to remove the old motherboard.... and you may as well then upgrade to windows 11 as well.
 
Well I have finally (after being away and generally not getting round to the daunting task) got it working. Nobody was more surprised than me after I rebooted from the Win10 install USB / Troubleshoot / Command Prompt area, and got the Win login screen :-)
I had done some fiddling in DOS a couple of weeks and made it worse rather than better, but I just ran
MBR2GPT.EXE /convert /disk:0 /allowfullos
and all is well.
So that's new Gigabyte MoBo, CPU, RAM and PSU all upgraded with no issues in Win10, certainly no suggestion from System / Properties that it is unhappy about activation.
