The new motherboard isn't supporting SSD booting.
The new motherboard isn't supporting SSD booting.
Here’s what happened: I switched from a Gigabyte Gaming Ultra to an MSI Z490 Unify meg board with an I5 10600k. Now I’m stuck and can’t boot any of my hard drives. The SSD appears in the BIOS hard drive menu but isn’t listed in the boot order. It doesn’t show up on any drives, including the CD drive. The new board has ClickBios 5 installed.
You need to transfer your setup files from the old SSD to the new Windows SSD. Since your hardware is different, you’ll likely want to use a tool like DiskPart or a GUI utility to move the necessary partitions and data. Make sure you back up any important settings before proceeding.
I've reviewed all the information available. The settings on the MSI board are under Advanced... Settings... Windows OS Configuration, but since this board hasn't ever run a Windows drive before, the Windows OS configuration section isn't present. When I tried using my Windows 10 CD, it simply indicated it couldn't convert. Even entering C: in the command line to select the C drive worked, but it still showed a conversion failure.
For those who search this up in three years with the same problem: you should have a recovery disk or USB drive. Open the Command Prompt and type 1.DISKPART to launch DiskPart. Then run 2.list to see all connected disks and their status. Note the disk number you have. Proceed with 4.mbr2gpt.exe /convert /allowfullOS /disk(yournumber) to convert the disk, remembering not to try this during another Windows install. This method works only from a Windows Recovery CD.
