I have a 8 GB flash drive and a 4.3 GB DVD iso (openSUSE-11.3) Is it possible to use the flash drive to install the linux? Pendrive linux universal USB installer formats it to Fat32 which limits the filesystem to 4 GB.
Yes. UNetbootin is a tool that will extract the ISO onto a thumbdrive so that you can boot from it. It should work like a DVD would, allowing you to install from the thumbdrive.
