Ok I don't know what to do, and decided to ask here, here's the problem :
I have a 8 GB flash disk that i use to boot image. I decided to try opensuse 12.3, and then i use unetbootin to extract it to my flash disk.
When i try to boot it says something like the machine didn't find any OS, so I do some googling and it says i have to use suse image writer to extract the image, so later my machine can detect it.
After using suse image writer, I can boot my flash disk containing opensuse, but the real problem is, the size of my flash disk is shrinked to 3.7 MB from 8 GB. I tried to format it but nothing happens.
Any hints? And sorry for the bad english.
