1. Copy Proxmox ISO image file into PVE Bootable USB stick.

2. Boot from USB on debug mode
(Type 'debug' when PVE boot: prompt)


3. Check Your USB Stick mount status

Normally, you'll see boot prompt ('#') with 'no cdrom found' message.

fdisk -l 


You can see mount status.


4. mount iso image.

mount /dev/sdb1 /mnt 

(note: the /dev/sdb1 represent my stick on my system — Please change this value to reflect your settings)


mount -o loop -t iso9660 /mnt/proxmox_1-7.iso /mnt
(again change accordingly based the name of your iso file… )


5. Install VE

chroot /mnt  sbin/unconfigured.sh
