Access Windows On Upgraded Desktop Build?

I recently decided to upgrade a very old build from 2010. So I purchased a brand new motherboard, CPU, RAM, GPU, and PSU and had them all swapped out. I am working on an SSD but it's taking forever to ship.

Anyway, since the upgrade, I cannot access Windows at all. The BIOS does know both drives exist and that only one has BOOTMGR but won't properly boot. If I try to boot from the drive with the OS, I get a bluescreen saying "inaccessible boot device" and it restarts into auto recovery which asks for my keyboard language - I cannot provide the answer though, because the keyboard doesn't work - in any USB port.

So I tried making a boot device on my USB. Same keyboard issue. I get to the installation screen, and I can't select anything because the keyboard is off.

I don't know what else to try or why this is happening. Is something corrupt or too old? Is there something I overlooked when setting up? I'm tearing my hair out ready to cry at this point. I spent a lot trying to update my old computer and I've gotten nowhere.

The only other thing I haven't tried is resetting the CMOS battery, which is currently behind the large GPU PCI card I had installed. (Great placement for a CMOS battery, really)

Your inaccessible boot device error is probably because you are trying to boot an MBR drive with an NTFS system partition in UEFI mode.

Boot to the BIOS and check if legacy devices are enabled in USB. or if there is a specific setting to disable usb ports.

I have checked and legacy devices are enabled by default. There's no setting I could find that disabled the USB ports.

Yes I do see where you're coming from and that's where I thought I saw a solution as well. A friend actually pointed that out.

I was on UEFI mode and it was just booting directly to the BIOS. He told me to switch to CSM (the other mode in my BIOS) and viola! It worked...or so I thought. The Windows logo popped up and seemed to start, but ended in the Blue Screen Error "inaccessible boot device"

Unless there's another setting I seem to be overlooking? I wouldn't be surprised if there's a setting I missed. The motherboard's a MSI - PRO B650-P WIFI and I flashed the BIOS to the current version on their website, so it's up to date.

Did the keyboard work within the BIOS.

Yes. Keyboard and Mouse work perfectly within the BIOS. And I can use the keyboard shortcuts beforehand as well. The Delete key will get me into the BIOS just fine and I assume the F keys work for their purposes as well.

I don't know why it shuts off the keyboard on Windows Installation, it doesn't make sense to me. Is there maybe a cheapo keyboard out there that will just work on all USBs with no installation needed?

"inaccessible boot device"

did it give a code ?

Can you get into SafeMode?

I'm afraid I'd see a repeat of what's happening here. Does Safe Mode require booting to work properly? When booting normally I get "inaccessible boot device"

Also I think I've tried hitting F8 numerous times with no results. Unless there's another way to get into Safe Mode?

Whatever the standard code is on the bluescreen itself would be all I could give you. I don't have a full stop code or anything. I'd have to check tomorrow though.
