maybe  you can-- I was following safest path

I dont have experience with booting from usb drives;
i think it takes some tricks in general not just for Quantian



Should I make multiple partitions on the usb drive and reserve separate

well that would probably be the safest;
but you might be able to store all the iso's in the same parrtition
once you had the rules down for booting from  a usb drive.


How should I organize the partition?  Leave it empty?


not  sure what  you mean  here;   not absolutely empty, it  has to have the
iso
and the   linux26, minitrt26.gz  has to be in the /boot,  in my case itself
a dir in dev/sdb7

not sure what you mean by "mixing programs"
unless you mean multiple different iso's in same partition,
which as i say above might work ok.



My sdb7  is in fact being used for two methods of running Quantian
1) the boot via grub
2)Quantian running via vmplayer,
in my case vmplayer running under fc5, see the howto on Dirk's site
ie
the one Qauntian.iso  in sdb7 is doing double duty



I have taken the liberty of including the quantian list for this reply
further discussion should take place thru it.

let me know if you learn how to boot from usb hdisks
regards,
Jack
