[SOLVED] Install from USB device

[panther-ra]

Hello. I have some troubles with installing from USB stick or HDD. I made usb stick with this command:
dd if=proxmox-ve_*.iso of=/dev/XYZ bs=1M , but when i try to boot i have an error:
searching form cdrom
testing again in 5 second. Then its drops to shell.
I made bootable USB|HDD with GRUB4dos, menu.lst:
title ProxMoxVE
map --mem --heads=0 --sectors-per-track=0 /linux/proxmox_ve_5.iso (hd32)
map --hook
root (hd32)
chainloader (hd32)
boot
But this error happen again. I suspect that ISO from download page not hybrid. Any suggestions?
ISO name: proxmox-ve_5.0-af4267bf-4.iso , i tried to download from HTTP and Bittorent

Maybe your usb stick has some leftover mbr, please try to clean out your usb stick and try again with dd (for testing, use dd without the bs option).
