Hi, i solved it. For future reference:

I changed PARTUUID=${uuid} to PARTUUID=745a7... (it's partuuid).

... but I'm not sure where (first line below or second) and how. [code] part uuid ${devtype} ${devnum}:2 uuid setenv bootargs console=tty1 root=PARTUUID=${uuid} rw rootwait smsc95xx.macaddr="${usbethaddr}"[/code] Any help would be appreciated!

Summary :

doesn't work:
MBR and PARTUUID (usb drive)
Hybrid MBR and PARTUUID (hard drive)
Hybrid MBR and /dev/sdX (hard drive)

works:
MBR with /dev/sda (usb drive)
GPT with PARTUUID (uab drive)

thanks for kind answer .

i guess i shoud do gdisk for partuuid .
is it right ?
