USB HDD is what you want.  A flash disk looks like an HDD (or should) if
you copied the diskboot.img file to it using dd:

    # dd if=/media/dvd/images/diskboot.img of=/dev/sda bs=512

and assuming your flash disk appeared as /dev/sda on the system you
copied it from.  I keep an cheap 128MB flash around for just such use.





Sorry but this did not work. Specifically, I did the following (my flash disk appeared as /dev/sdb1 but it was not recognized on boot:-( and the laptop went into MS Vista (yuck!). The boot priority order is current CD, USB CD, +USB HDD (I don't understand why there is a + before USB HDD and then ATA HD0. 

One other question I wonder is whether I should have unmounted the disk the usual way (I used nautlus's unmount volume).
Is this the correct thing to have done?

Many thanks and best wishes,
Trotter
