    How did you create your USB Stick?

    And make sure you select the USB boot on your mainboard.

    @niuk: I had problems with that too. Try different USB Sticks and different methods to write the ISO to the USB stick.
    If all else fails burn a CD or an external HDD wich emulates a ODD drive - I took the last route because I regulary need this and would not trade it in again :)

    Hi,
    "formatted on Linux" makes no sense, because you overwrite any formatting with dd!

    Do you use the same USB-port on the server? Perhaps the bios don't support all ports for booting?!

    Hi,
    do you sync after dd and write long enough before disconnected the usb-stick? (the sync must be finished)

    And again - it's helpless to format the usb-stick before write an iso with dd onto the disk. the dd overwrite an excisting format!

    I used this command: dd if=proxmox-ve_*.iso of=/dev/XYZ bs=1M as the wiki recommended.

    Hi,
    this is correct, but you must do an "sync" after that and wait with disconnect the stick until the sync is finished. Otherwise it's can happen that not all data is written to the usb-stick.

    So the correct command would be this ? : dd if=proxmox-ve_*.iso of=/dev/XYZ bs=1M conv=sync

    I did this, the process is only 2 seconds, but the problem is the same.
    Maybe there is something wrong in my BIOS setup.

    Hi,
    2 sec. are much to less. Has your downloaded iso the right size?
    you can use this methods:
    Code:
    dd if=proxmox-ve_*.iso of=/dev/XYZ bs=1M; sync
    
    dd if=proxmox-ve_*.iso of=/dev/XYZ bs=1M conv=fdatasync
    
    An cheap USB-Stick write app. 5MB/s - so the dd takes round 100 second:
    Code:
    ls -l Downloads/proxmox-ve_4.4-eb2d6f1e-2.iso | awk '{print $5/(1024^2*5)}'
    104.359

    I tried the both way, and 2 pendrives, the process was around 1 minute. Problem is the same.
    I got the same 104.359 result, so the iso should be ok.

    Hi,
    the same size of the iso don't say, that the iso is correct - for this you should compare the hash.
    Code:
    md5sum Downloads/proxmox-ve_4.4-eb2d6f1e-2.iso
    e453b3e1038d8b95f4a6d12cb233c389  Downloads/proxmox-ve_4.4-eb2d6f1e-2.iso
    
    compare with https://www.proxmox.com/en/downloads/item/proxmox-ve-4-4-iso-installer

    But perhaps you must change something in your bios to boot from the USB-Stick - like bios/efi-boot, boot order, type of usb-handling?

    What kind of hardware do you have? I had problems with older servers and in general older motherboards using usb boot. In those cases, I use a usb dvd drive and a dvdrw disk to avoid hours of fruitless struggle. This method always worked.

    In any case, double-check you're not booting off anything but the usb drive.

    I have got a PC with Gigabyte motherboard, 8 GB RAM and 500 GB HDD. The processor is an Intel Pentium dual core.
    I built a new PC with Intel core i7 and with 16 GB RAM, and i would like to use this older PC for test and learning purposes.
