[SOLVED] Computer doesn't find boot devices after motherboard upgrade to Z390-E Gaming, cant boot into windows 10 from SSD

[Bluetoofe]

I recently decided to upgrade my motherboard, CPU, RAM and power supply. I was under The impression that I would be able to boots from my solid state drive after installing everything, but I guess I was mistaken. When I 1st power on the computer, everything seems to work and all my devices are recognized, but I can't see any of my hard drives as boot devices, and I don't currently have a windows 10 installation device that I couldn't plug in to USB or the CD drive. I am not exactly sure what to do at this point, as I thought it would just be as simple as booting from my original device.

I know that I possibly screwed up because I know you're supposed to find windows 10 installation media before you do the hardware changes but I was wondering if there was a solution to get around that. If anyone could help me out that would be awesome.

You must reinstall windows to operate the new system. Acquire a usb drive 32GB or larger and follow these steps. Save your data first.

Create an up to date USB install media by following the steps outlined here:

Then disconnect or disable all hdd /ssd drives but the one where you will install windows.

Insert the USB media tool, with the windows install files, into the board. Next startup and go to the board setup and ensure the board is configured to use UEFI boot settings, CSM is enabled and SATA mode set to AHCI.

On the motherboard boot device menu, select the command that identifies both the firmware mode and the device. For example, select UEFI: USB Drive or Windows Boot Manager: USB, and list that device in the first boot slot on the board.

Reboot. Install begins.

When choosing an installation type, select Custom. On new disks, the drive will show a single area of unallocated space. If there are partitions, select each one and then "delete".

Select the unallocated space and click Next. Windows detects that the PC was booted into UEFI mode, partitions the drive using the GPT and begins the installation.

NOTE: Any data on the drive will be lost
