Hi,
On the old BIOS systems, if I wanted to swap hard drives on a system
(e.g. move over to a bigger one), I could clone it off-line, then swap
over, and it'd just work.
Should I expect a UEFI system to do it that simply?
And do secure boot options throw any spanners in the works, too?
I tried this last night, and it didn't want to boot. I cloned it using
"dd if=/dev/sda of=/dev/sdb" while booted from a gparted ISO on a USB
flashdrive (current release). Shut down. Unplugged the old drive.
Rebooted.
If it makes any difference, I can't recall if I plugged it into the
same SATA port on the motherboard. It's a board with 6 sockets, and
I'm only using two of them (DVD and HDD).
I did get it to boot by messing with the boot menus in UEFI, but it was
quite hit-and-miss about what to boot from. I can't remember now if I
selected the drive with it on, or the entry with the release's name in
it, but neither worked on the first boot. It was a few reboots before
I got it to go.
