Hi all,
I tried to create modified Windows 10/11 boot media for use with VMWare Workstation 15. I downloaded the final ISOs for Windows 10 and Windows 11 from Microsoft, they boot and install fine in VMWare 15.
I then unpackerd the ISO to a local folder, added a bunch of files, and used ImageBurn to create a new ISO. I have set the "Advanced" properties for "Bootable Disc" like follows:
Emulation: none
Boot-Image: path to ..\boot\efsboot.com of the unpacked ISO
Platform ID: 80x86
Developer ID: Microsoft Corporation
Load Segment: 07C0
Sectors to load: 8
Nonetheless neither a newly created Windows 10 nor Windows 11 ISO boots any more.
What I noted is that the created ISOs, even if I don't modify any of the ISO contents, but simply "repack" it to test the bootability, that they are slightly smaller than the originals, e.g. for WIndows 10: 5760336 KB (original) vs 5758656 KB (re-cerated).
Am I missing something, or is ImgBurn simply unable to create bootable ISOs for Windows?
Computer used is plain vanilla Windows (Version 10.0.19043.1766), settings on defaults., no antivirus installed. VMWare Workstation 15.
Thnx, Armin.
