Windows 10 won't boot - fresh install

Please post images of the the BIOS drives and menus.

These you can use the snipping tool:
Disk management
File explorer
Device manager disk drives

Setting to default sets all the boot priorities and other items as factory fresh. That's what we're attempting to accomplish.

We can't assume that OSs along the way haven't changed anything.

Sorry I took so long, but the BIOS should have been set to default not just UEFI mode.

OK, you lost me here. If I go to the BIOS and look under Settings -> General -> Boot Sequence, I see this...



This is the only place I can see any mention of UEFI. It was previously set to Legacy, and following your comment, I changed it to UEFI.

Can you see that secondary drive in your BIOS at all in the boot section?

As you can see, it doesn't show in the picture above, although I'm not sure if it should as it's not a bootable disk.

However, under Settings -> General -> System Information, the drive does show up...



Also, if I look under Settings -> System Configuration -> Drives, I can see it...



Does that help? Thanks again.

P.S. Thanks also to zbook, turns out it was a good idea after all!

I'm not familiar with that Dell BIOS is the problem I have. I have Asus. Check documentation. Does it have an option to set to default?

Have no idea why Disk Management is not seeing the drive with the pics you posted.

Ah, seems a couple of replies came in while I was typing. Do I assume that by "setting to default" you meant hit the Load Defaults button in the BIOS? I'll tried that, but when I rebooted, it didn't load Windows. After the BIOS messages, I got "Invalid partition table!"

Here is the drives display in the BIOS messages. This hasn't changed over the course of this whole sage...



As you can see, it shows both drives.

If I go into the BIOS, then the System Information section shows the same as before, but the Boot Sequence now shows more. This is actually what it looked like before I enabled the UEFI...



The System Configuration -> Drives section looks as before.

So, the BIOS can see both drives, but now it won't let me boot. What do I do now? Thanks again

Hmm, I just tried unplugging the second drive and rebooting, and it now says "No Boot Device Found"

Not sure what's going on here, as the only drive left plugged in is the one with the fresh Windows install.

Ulp.

Yes, load to defaults and save. Once again I think Windows formatted it as MBR scheme and not GPT. That's my hunch anyway.

I'd say to start over, wiping the disk, and reinstall now that you have defaults loaded and saved.

Leave both disks installed along with the USB thumb and pull anything else.

Plugged the SSD into my lap top and used Computer Management to look at it. It seems to think it's OK...



What do I do now? I can wipe the disk and start all over yet again, bu I can't see that's going to help. I did that earlier, and still had problems. Mind you, that was with enabling UEFI. I can reinstall leaving that as the default.

Any comments?

Ah, you replied while I was typing! OK, here goes yet again...
