The only other device is the USB drive I booted from. I've not had a chance yet to really look at what's going on, but it looks as if it's not waiting long enough as it reports no installable devices. If I then check when it exits to the shell I can see the drive is there and re-running the script then means it does find it (the script then fails for other reasons to do with the failed run).

It will sometimes install, so it looks as if the wait is nearly long enough.

I'm using an ATP AF512SSGH if that makes a difference.

BTW the change I need to make to the grub file is partially related - the boot device is sda and the internal (install target) is sdb. Grub gets configured to boot from sdb but the device is sda on a clean boot.
