Hi,

I am trying to reinstall the latest version of Proxmox (8.1) but having some issues.

Steps:
I downloaded the latest proxmox version from here
I installed the USB imager to make the USB rebootable using GTK+ version for Ubuntu LTS from here

Problem:
I boot from the usb then I get proxmox installation screen.
I select the option "Install Proxmox VE"
Then get some logs on the terminal like screen.
Then it reboots back from the start into the usb and I get the installation screen again.

It's like a loop in which I am stuck. Is there a way to get rid of this problem. I am really desperate to solve this issue.

Note: The previous version of Proxmox 7.1 was already installed in this server. So I am trying to re-install Proxmox.

Immediate help would be much appreciated.

Thanks
 
I have the same issue, and I also started getting an error in the terminal screen, which said no suitable ISO found. It happens after a few moments, after selecting "Install Proxmox VE"

Most likely: Your installation media is faulty.

I recommend this very-old-but-very-relevant post about verifying boot media: https://www.troubleshooters.com/linux/coasterless.htm

isoinfo is your friend - Use it wisely!

Pay special attention to the "Volume size" field in the output - You'll use that with dd and md5sum to verify the important bits.

Thanks guys, this was driving me nuts. I have been too comfortable using Ventoy on USB to mount install ISO's and most distros have no issue with it, but Proxmox doesn't like it. Once I installed the ISO on the USB with Etcher, it installed without issue.

Thanks for your time!
