How to rebuild corrupted windows?

i have a Windows 10 drive from another PC ( Disk 1, E: ) that only has its Windows files (like the main partition, see pic below) but its original EFI and recovery partition is in another ssd that we can't find.

    Deployment Image Servicing and Management (DISM).

    This tool repairs the Windows image that SFC uses. If SFC fails, run this first and then try SFC again.

    DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

    Use Windows Startup Repair (Automatic Repair)​​.

     This is the first tool you should try. It's designed to fix common boot problems automatically.

    If the drive contains important data, back it up before attempting repairs. Alternatively, you might clone the data to a new drive and perform a clean Windows install, which will automatically set up EFI and recovery partitions properly.
