How to create ISO image from WIM?

Question

System administration

Dear, tell me about the problem of creating ISO .
There is an installation flash drive with windows server 2008 r2 (standard, enterprise, datacenter). There are directories boot , sources , efi, ... In the sources directory there is a 2.7GB install.wim file , from which the Dism++ program managed to get only the required enterprise assembly .
I can't figure out what means and how can I now create an ISO image so that it can be used in qemu-kvm to install Windows?

Googling for the phrase "convert wim to iso" leads to continuous manuals and tools for windows 10, when launched, errors like "the desired file was not found" appear.

Answer 2

Actually in install.wim is the file system image of the system disk. You can make an iso out of it - but you won't be able to boot from it. So you just need to replace it on a USB flash drive and write all the files to iso indicating the bootloader.

Answer 3

You don't need to convert WIM to ISO, you need to package the FULL installation CD structure into ISO.
You can customize the WIM file - cut out unnecessary revisions, etc.), but it should lie in Sources in its place.
You can do this with the official CD Image utility from Microsoft.
