does a debian bullseye image also work? you can try installing PVE on top of that as well [0]

you can also install PVE6 and then upgrade it to PVE7 [1]

most of the time the black screen issues come from missing display drivers or incompatibilities with your hardware.
it would be interesting to know what kind of hardware you're using.

I am having the exact issue. I am trying to install on Fan-less Mini PC Celeron N5105 with 6 Port 2.5G LAN from KingnovyPC . Did you find a way round to install successfully?
 
Thanks for the heads up. I have since managed to install pfsense on that machine. And it loaded up ok. I have to check & test how well pfsense runs. I do think it's a video output / resolution / refresh rate issue with proxmox installer. I can't even go through the installation process in the first place because the screen goes blank. The issues you highlighted comes after installing proxmox. I'm not even there yet! I will try a different monitor later.

My main aim is to run pfsense stable. So I may abandon the idea of a hypervisor altogether if I can get pfsense running well. It's just that there will be a lot of processing and ram left unutilised.

Was only meant as a information/warning, that even if you get through the black screen problem, you may get a unpleasant experience. Especially if you rely on this system as with a pfSense.

Just an update. I did manage to install Proxmox 7.2 today. It was very likely display/refresh rate issue. It would go blank on my 75Hz QHD ultrawide monitor. I hooked it up to my son's 1080p 60Hz monitor via HDMI and the display worked with out any issues and I managed to install with out any issues. Now to go and test things with pfsense. If I do start getting problems, I will just go baremetal pfsense.

Good day all,

Sorry to revive an old thread but I'm having the exact same issues trying to install Proxmox 7.4.
The install will start but after about 5 seconds the screen goes black.
I'm trying to install it on a HP DL380 Gen7, I've tried using a simple monitor and a 26" Philips TV but both give the same out come.
 
Hello. Writing here just in case if someone needs:
I had the same problem with Proxmox 7.4 and HP 360 g7. After choosing 'install proxmox' I had monitor out-of-sync - probably because not supported refresh rate. Generally hints in other posts are correct however I fought a little bit to make it work.
Below the procedure which worked for me (with old 15 inch monitor and resolution 1024x768).

The Procedure:
1. Write Proxmox on USB Key and choose to start server from USB
2. On the Proxmox Grub screen move to (highlight) option "Install Proxmox", and press 'e'
2. You are in the grub edition mode, add the following text at the end of the kernel parameters: module_blacklist=radeonfb nomodeset
3. Click F10 to continue with the installation
4. There will be a problem with the GUI and the installer will fail back to the console
5. Edit file: /usr/share/X11/xorg.conf.d/10-quirks.conf
with eg. nano edtor
> cd /usr/share/X11/xorg.conf.d/
> nano 10-quirks.conf

Add section in the file (with correct indents):

Section "Device"
ID "Card0"
Driver "fbdev"
EndSection

6. Save the file, and exit the nano editor.
7. In console run command:
xinit
8. The installer should start without problems, continue with the proxmox installation...
