Hi! New user trying to get into proxmox with an old desktop I had lying around but I've been having some issues getting it up and running. For context it's an old eMachines running an Athlon II X4 640 with 8 GB of DDR3, a GT 730 for display out, and has a 512 GB SATA SSD that I'm trying to install it to. Some of these were modifications throughout its life but it ran Ubuntu before so I figured it'd have no problems running Proxmox. One hiccup was having to set it to nomodeset or else the installer would hang but with that hurdle cleared, nothing else seemed to be going wrong during install. Despite that it would keep booting to grub rescue with the error: no such partition after the installer finished. I've tried rebooting the system manually, using Balena Etcher instead of Rufus, using a USB 2.0 flash drive instead of a 3.0, even redownloading the ISO and flashers a few times to make sure nothing is corrupted. Nothing alleviated the issue and since I can't find any seeming related incidents I don't know how to troubleshoot other than what I've tried so far. Any recommendations are appreciated!
 
Let it boot until there ... then just type "exit" and use enter key ... look what happen ... :)
Thanks for the recommendation but exit gives "no command found". Ls gives a few GPT partitions though so maybe I can work with that.
 
Insmod seems unable to detect the file system so I'm kind of skeptical as to whether or not it's been installing to target disk. I'll try one more reinstall with logs up but considering it's been rebooting after each attempt nothing is being flagged by the installer.
 
I assume you installed "pve with zfs" and there is race condition where the pool isn't imported and so landing in grub.

Sorry, it's been landing me to grub rescue, not grub. I'm also selecting xfs instead of zfs during the installations since I only have 1 SSD on it atm and won't be doing anything worth parity.

Nada. This is either a really obscure hardware config problem or a really obscure software problem. Either way I don't really have the time nor will to make this project longer than a day so I'm just going to install vanilla debian, which does install despite proxmox installer refusing to, and then use the guide to convert that to proxmox. Thank you for trying to guide me waltar.
