unetbootin boot error
 

Hi I have Debian installed on my PC and I would like to install another Linux distro in a free partition, my cdrom device does not work so I have been trying to install from memstick this is what I do:
1. Create a FAT32 bootable partition using cfdisk
2. use mkdosfs -F 32 to create the filesystem on partition
3. use unetbootin to make the install media using a *.iso file
I don't get any error message during the process, but when I reboot the PC I get a "boot error" message. What can I do?

Maybe there is a certain procedure, for that other distro, in order to make it boot from usb.
The same applies for debian.

What is that procedure for Debian?
Is there another application/procedure in Debian to make a bootable memstick?

You download the branch specific boot.img.gz from

http://http.us.debian.org/debian/dis...ages/hd-media/

or

http://http.us.debian.org/debian/dis...ages/hd-media/

and you "burn" it on the usb stick (which has to be unmounted at that time) with
Once done, you mount it regularly and copy the stable/testing iso you want in it. And done!
