I'm attempting to install Windows 11 on Proxmox VE 7.3-6, using a verified ISO directly from Microsoft (SHA256 checked). The VM uses OVMF (UEFI) with TPM 2.0 and an 8GB RAM / 2-core config.
The problem:
When I boot the VM, it prompts:
Press any key to boot from CD/DVD...
I press a key, the Proxmox splash screen appears for 5 seconds or so, and then it disappears and I'm prompted again to press any key — in an infinite loop. The actual Windows 11 installer never starts. If I don’t press a key, it eventually tries PXE boot.
This seems like it's failing to continue booting from the ISO and instead restarts the "press any key" prompt each time.
The VM Config:
Any help would be appreciated!

What I've tried:
- Changed the CD/DVD interface from IDE to SATA
- Verified ISO integrity (Win11_24H2_English_x64.iso, official)
- Tried both Q35 and i440fx machine types
