how to keep existing EFI partition while reinstalling proxmox

[mehoweck]

I am experimentally installing proxmox in the thin client's eMMC memory, there is also a Windows EFI partition in this location. After the first installation I had to fix Windows booting. Now I would like to reinstall proxmox again (I gave up with the WiFi connection config) and I don't want to mess up Windows booting. Is there a way to keep the EFI partition unchanged? So that I don't have to repair Windows again?
thx a lot

No, yet I recommend backing the EFI filesystem up and restore the entries after PVE reinstall. Every operating system I know is very "consuming" and will wipe everything there is because they want to ensure that their product will work.

ok, clear, thank you for such quick answer
but maybe a different approach - I just want to change the active network interface from WiFi to Ethernet. Is there any convenient way to do this, like during the installation process?

Finally I created for Windows its own EFI partition on its own drive and then reinstalled Proxmox.
Everything works
thank you for your help

I'm unaware of such a setting. Generally, WiFi is not bridgeable (just a very, very small percentage of WiFi chips out there are capable), so it'll not work with VMs. After the installation, you can just use the normal debian way to enslave nics into the bridge.
