I don't believe your ocsdimg command line is correct for a UEFI bootable iso. see docs:

To extract an existing Windows PE ISO file, add files to it, and make it bootable again, you can follow these steps:

1. Extract the Existing ISO:
   • Use a tool like 7-Zip or WinRAR to extract the contents of the original Windows PE ISO file.
     • Create a new folder where you want to store and modify the extracted files.
     1. Add Files:
        • Copy any additional files that you want to include into this newly created folder. These could be drivers, scripts, executables or other necessary components for your customized version of Windows PE.
        1. Modify Configuration (Optional): If needed, Edit configuration settings such as startnet.cmd, winpeshl.ini etc., based on specific requirements
        2. Create Bootable Image:

• To create a bootable image from modified content/folder structure
• You’ll need external tools capable creating iso images e.g., ImgBurn , PowerISO

5 . Open chosen software/tool & select “create image” option typically found in menu bar

6 . Select appropriate options within UI provided by selected application : * Choose source directory containing all previously added/modified windows pe related folders/files * Specify output path/name/location desired for resulting iso being generated

7 . Configure Boot Information : Ensure proper configurations set up so resultant Iso is marked/booted correctly when used later

8.Click ‘Start’/‘Generate’/similar button depending upon which program utilized

9.Wait until process completes successfully without errors/warnings.

10.Verify Resulting Output File : Check if final result meets expectations i.e.,

• Verify whether changes made are reflected properly after mounting/burning/reusing updated iso
