I’ve made several times bootable usb stick, either with a fat filesystem or a linux one, but I can’t install a dual boot. is it possible?
regards
As an USB stick mimics s mass-storage and as such mimics a disk, I do not see the difference between installing on a PCI connected disk or an USB connected stick.
Only thing is that USB devices tend to be taken away from the system and then connected to other systems. Which means that references to the device itself within the device (like partition definitions in GRUB and /etc/fstab) should not be by e.g. /dev/sdb, but by-id or by-uuid.
It’s not clear what you are trying to do here. Dual boot what and what?
Also not clear how you make the sticks. The file system on the stick is immaterial since a proper copy of the iso will change it any way.
So maybe explain your problem a bit more clearly. Do you want several OS’s on one stick? If so you need to install to the stick ie treat it as a drive just install to it
If you want an installer on the stick do a binary copy of the iso to the device (not a partition) cp xxxx.iso /dev/sdx will work wher x is the device number of the stick or you can use dd or if working from Windows Image USB will work http://www.osforensics.com/tools/write-usb-images.html
Note that USB sticks use flash and do not in general have write leveling and other features a SSD would have so have a very limited write life. ie they fail if you do lots of writes So if you reun a OS from one don’t expect it to last too long
Yes, and there are instructions how in another thread in these forums that was posted a few weeks ago.

Yes, it is possible to multiple boot from from usb stick. http://goo.gl/3EuY8b http://goo.gl/3n8tl8
