How do you make that Windows Server 2025 into a Proxmox 8.1 Template?

[TazzSmk]

I got "Windows Server installation has failed" lolz xD
EDIT: did another reboot, wiped half-done install, and it installed at second try - perhaps latest Proxmox is still picky about latest Server 2025 build

[MouhammudMarai-rwpk]

does it require tpm, secure boot and modern cpu?

Sup. how do you make a custom storage like yours called ISO?
