I was trying to create a liveUSB with many distros. The reason is simple. All of my USB sticks were quite big for only one distro. So the rest of the USB space is wasted. For example, the openSUSE USBs I got from conferences, are 8GB. If I use installation DVD, I’m going to use only 4GB. LiveGNOME is only 1GB (the rest would be persistent drive for storage but personally, I don’t use it.
For that reason, I used 2 programs.
I translated to Greek. Unfortunately, this software is installed only on Ubuntu/Debian distros. I used it also on Arch Linux but there was a problem lately and didn’t work correctly. On Ubuntu, I managed to insert 13.1 successfully and lately this was difficult to do. At the end of each time, there were some strange symbols running for a quite long time with a sound (I muted the sound for that reason). I think persistent drive for 13.2 and Tumbleweed wasn’t something that the creators of the program added.
DVD ISO and NET install ISO wasn’t at their list either.
This works on Windows. At the end of the page there’s a version for Ubuntu/Debian (and source code). I didn’t test them.
I tested this tool and I inserted NET install ISOs to an old 512MB USB I had. The only “negative” is that there wasn’t room left for the ISOs I wanted. 90MB x 4 = 360MB. It adds syslinux stuff. Anyways, at least I can use a very old USB.
