Hello,
I'm new to proxmox VE but I tried everything I could find online in order to solve my problem:

Configuration: z690, i9 13900k, 128GB RAM, 3080 12GB

I'm trying to install the latest Proxmox VE iso on a nvme (there're other drives with OS's installed plugged into the same mobo) but I keep getting "file `/boot/` not found" seconds before the installation screen pops up.

The checksum is the same as the website, I tried burning the USB using balena and rufus. Everything on UEFI mode, CSM disabled, secure boot disabled.

When I select install, it freezes while loading files. Tried accessing the command line but I didn't really know what to type so I tried the "break=bottom" command, following Gemini instructions.

I tried Rescue Boot option and it gives me "error no such file: rpool", so I tried some stuff with the SATA controllers but to no avail.

Please, let me know what I'm doing wrong.

edit: fast boot also disabled

Hello soviet,

what does mean "there're other drives with OS's installed plugged into the same mobo"? What is the purpose of these drives?

Try to disconnect all drives and let connected just the one where you want to install PVE. Also disconnect for PVE not necessary USB devices.

These drivers are other OSs I use, that's the main reason I want to move to proxmox is being able to use different OSs at once.

I tried your suggestion but I keep getting the same error, letting only keyboard, pve usb and the nvme connected.
 
Right now, I'm considering two possibilities:

1) Secure Boot on the motherboard might be blocking the PVE system from booting. The GRUB in the PVE image should be signed, but your motherboard may not trust the certificate. I've read some reports about a Windows 11 update that can break a dual-boot setup.
  • Try disabling Secure Boot.
  • Try disabling EFI boot and using CMS.
  • At last try factory reset EFI settings
2) RAM (or other hardware) issue
  • Check memory integrity using Memtest86+, running at least two passes.
If these steps don't help, please provide more information about the point where the boot process stops. Disable the full-screen logo (if enabled) and look for any error messages. Do you see the GRUB menu? Who wrote the "file /boot/ not found" error message—the EFI shell or something else?

Hello!

Sorry for not updating, I had some personal problems going on

I tried a different solution and it worked:

On the linux /boot/linux26 line, I removed the quiet and splash (some versions might be splash=silent ) and wrote nomodeset.
It solved my problem on booting, apparently it's gpu driver related. But then I started having another one, console related.

I find PVE on the network, I access its browser page, I have the iso location mounted on the proxmox, but whenever i try to boot it, i get a black screen.
I've redone the VM configuration a couple of times, always checking if there were no video configurations that could be causing this problem, I even tried different combinations of video driver but to no avail. PVE terminal says my VMID is running. (I'm using a cellphone to run the PVE browser page, I dont have another PC at the moment).

Anyways, thank you for your attention and help!
