I have been getting a very nice headache with this very specific problem or "bug" some might with a GPU making the Proxmox VE installer and OS boot for some reason. I think this could be a bug with the drivers that are included with the PVE Installer and those that are in the OS once it is installed.
This is the combination I'm using: AMD Ryzen 3600 + MSI B450 Gaming Plus + 4x8gb ram at 2133 + m.2 sk hynix 500gb ssd
-I did move around components and have switched them one by one too. Other components I used: Gigabyte A520M-K v2 Motherboard, AMD Ryzen 5600x, 2x16 Kingston Fury Beast DDR4 at 3200mhz and some lower capacity and speed ram too , different Sata and M.2 ssds just to be sure and finally the ASUS GT1030 2Gb Low Profile Active Cooled GPU
-First I did use Ventoy (always the latest version) and got a feeling that caused it, but then flashed the installer directly and this was deemed not to be the issue.
-Also have tried moving around RAM, storage, and even an other CPU (AMD Ryzen 5600x) until I thought the only thing left was the GT710 card.
-I tested this with the next PVE versions: 9.0.3 and 9.1.1 - And for Proxmox Datacenter Manager: BETA 0.9 , Release 1.1-1 -> The issue was replicated on all of these, but did not appear on other Linux distros or Windows 11 Pro with the same setup.
With the ASUS GT710 2gb with passive cooler there is an issue and no boot parameter (so nomodeset or others) or anything worked to even get the installer running and with an afterfact GPU swap (install first on a different GPU and switch to GT710 after the install) the boot would sometimes worked flawlessly, sometimes half of the hardware wouldn't be recognized (storage devices via onboard sata, pcie devices and other component connected to the motherboard). The GT1030 2gb also from ASUS with the same "style" cooler but the cooler being smaller and with a fan, the issue completely disappears, and the installer is now able to work and booting is not a problem anymore.
My conclusion is that something conflicts with something that must have something to do with this GPU, I do not think it is only mine, but could be this model. I shamelassly did ask an AI but because I did not find anything anywhere and after lots of hours of testing I thought it was either motherboard or GPU until I somehow got it to work. And I do not have anyone around that knows that much about PCs or Linux, and Proxmox is completely unknown here sadly.
PD: If anyone need I can upload photos of the GPU I mention.
[UPDATE] I messed up the model, it was not the GT730 but the GT710 I had the problem with. I also corrected misspelled words.
