Multi-boot usb drive
 

I tried to research this topic but didn't find anything to what I want to achieve.

What I would like to do is use a USB Drive that has a multi-boot on it (say opensuse, ultimate boot cd etc) that I can plug into various machines and use to help fixing pcs.

Firstly is this possible? and if so could anyone point me into the direction of a tutorial or something?

Many thanks in advance =)

Try SmartBootManager.
Quote: 'Smart Boot Manager (SBM) is an OS independent and full-featured boot manager with an easy-to-use user interface. The main goals of SBM are Absolutly OS independent, Flexable and Full-Featured. It has all of the features needed to boot a variety of OSes from several kinds of media, while keeping its size no more than 30K bytes.' (written in assembler)
I have used it on a usb-stick, and it works fine. It will find all partitions and bootsectors and save the result to memory,
including cdrom-drives, usb-sticks and floppy-drives. (E.g.: usb could be named FD1)
It has selfcontained usermanual, F1.
So 'cat sbootmgr.dsk > /dev/sdb1' (or whatever your usb-stic is called).

Thanks I'll give it a go =D

After my answer to you I thought, better try this again. (I used it last time a couple of years ago)
So I made 2 usb-keys, 1 worked but only on one of my 2 computers.
The safe way for SmartBootManager is on a floppy-disk or cdrom. There is an .iso on the
SmartBootManager site too.
For the floppy it seems to work best with 'fdformat /dev/fd0u1440'
before duplicating the image to disk, use 'cat' or 'dd'.

Linux binaies
 

Just wondering if anybody knew what is used to interpret(compile?) the binaries in linux when they are ran?

And also, how does source code become binaries?

thx

You should start your own post instead. A compiler compiles binaries. Hence the name! Linux uses gcc or g++ to compile C and C++ source code respectively.
