Hello!
I'm new to proxmox and i ran into problems while setting it up.
I already successfully installed proxmox on my AMD FX 4300.
But i made a mistake so i was going to start from scratch.
When i tried to install Proxmox again it didn't work out.
So i installed fedora to check if there are port related problems, but keyboard and mouse do work with fedora out-of-the-box.
Afterwards I tried again to install Proxmox.
Upon arriving at the page with the the agreement my mouse and keyboard disappears, even the power of the devices is off.
At my first install i didn't have these problems.
I tried other ports, but no success. I read here about some UEFI settings to make it run (again) but no success.
My Setup (for a homelab) is not up to date but it was running:
I've got a AMD FX 4300 on a Gigabyte 970A-UD3P Mainboard, equipped with 24GB RAM.

May someone have ideas what i can do to get it running again?

Best,
Mettigel
 
Before the welcome screen appears i can see error messages.
But the welcome screen comes so fast that i cant read the error messages.
The only thing i could read is efi...
 
i could catch the erros which appear directly after Welcome to GRUB:
error: file '/EFI/' could not found.
error: no such device: /.disk/info.
error: no such device: /.disk/mini-info.

To solve it i tried a different USB Stick, but still no success.

Debian has the same problem.

Hi mettigel, I'm sorry you are experiencing this problem, from the error messages it seems, your device does not pick up USB devices plugged in.

Does this thread on Stackoverflow help? Link: https://askubuntu.com/questions/7704/unable-to-enumerate-usb-device

Specifically, the last answer seems to be helpful, considering you have a motherboard from the same manufacturer as the poster of the last answer.
I had this problem with a Ubuntu 12.04 64-bit Live CD. It prevented all USB devices from working, which in my case was a wireless mouse and a wifi router. The hardware worked fine on the same machine in windows7 and with the 32-bit Ubuntu 12.04.

The fix was to enable IOMMU in the BIOS of my Gigabyte GA-990A-D3 motherboard. Everything works fine after that change.

I would also additionally make sure all USB devices are plugged into the correct ports for your device.

thank you aabraham.
unfortunately i couldn't solve it. When I enable IOMMU in the UEFI the installation stops.
The last lines are:
Bash: 
searching for block device containing the iso proxmox-ve-8.3-1
with ISO ID '(long  hexnumber)'
I tried all 8 possible settings with IOUMMU, XHCI and EHCI

All USB ports are functional, front and back.
Also I tried different USB-ports and addionally i unplugged the usb-device (exept the flash drive with the proxmos iso) and connected them to another port.

Try to use only a USB 2.0 port for both the installation flash drive & the mouse/keyb.
You seem to have numerous USB ports. If you are you using a USB hub change it or remove it.
Now looking at you M/B info, I do see it has loads of USB ports, but what I notice it has some feature called "GIGABYTE On/Off Charge™", I believe that is some high-current charging circuitry on the USB bus (for PD charging etc.). I'd also turn that off in the BIOS if you can.
 
its finally installing. Thank you guys!
It seems that the "erp" setting caused it. And thats a setting without description in the UEFI.
