It appears USB related. I have built a GPT system on a SATA drive on a Lenovo T520. Works just fine. Always has. I copied the system onto a USB drive of the same size, not with dd of the disk, but by using gpart(8) to set up the disk including pmbr and gptmbr, just like I did on the SATA drive and then used dd to copy y\the partitions. I did this just to avoid issues with the"final block" as, while both drives are 750GB, they are different models Well, the Lenovo refuses to boot from the USB drive. It does not show up in the list of possible boot devices. I looks like this is an issue with GPT on USB devices, though I could well be missing another explanation. -- R.
