[PVE-User] 3.4 ISO boot problem on HP xw4400 workstation

[Eneko Lacunza]

Hi all,

I'm preparing a pair of HP xw4400 workstations for a 3-morning 
presentation next week about Proxmox and Ceph, but I seem unable to boot 
Proxmox 3.4 installer from USB Pendrive media.
I have tried:

37efacd45b70d5d720b11b468f26136b  proxmox-ve_3.4-102d4547-6.iso
215a582a53824772298c5171a48291d4  proxmox-ve_3.4-3f2d890e-1.iso


The same media works OK on other PCs, and the HP workstations boot OK 
from a USB CDROM and also from Proxmox 3.3 USB Pendrive:

b2531905a538bf01eebc25ee41aba0dc  proxmox-ve_3.3-a06c9f73-2.iso

Any idea what can be happening? Maybe it's because the new ISOs are 
using GPT instead of MBR?

Cheers
Eneko
