Hi, and thanks for your report.
InterLinked <deb...@phreaknet.org> (2024-12-16): > The Debian 12 installer (any minor version) fails to install on HyperV > on Windows Server 2008 R2. For demonstration purposes, I am using the > debian-12.6.0-amd64-netinst ISO installer. > > Debian 12 installs on HyperV in Windows Server 2019, and Debian 11 (any > version) also installs successfully in HyperV on Windows Server 2008 R2. > Therefore, the issue seems to be limited to a regression within the > Debian 12 installer itself. > > Issues are as follows: > > * Detect network hardware step fails with the default network adapter > in HyperV.

Do you happen to know the names of the Linux kernel modules that'd be required to support those devices? You could try and run a Debian Live image to check whether kernel support is missing entirely (from the Linux kernel packages) or “just” from within the installer.
