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 :)

Regards,
Jonas

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!

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.
