[SOLVED] - How to create boot usb disk on MacOS X (Linux and Windows maybe)

Hi,

I'm new around here and i was looking how to make USB boot disk on MacOS X and did not find any useful information on the net (no Windows in my home )

After trying i managed to get it working here is how.

1. download unetbootin from http://unetbootin.sourceforge.net/  for your OS

2. plug usb stick at least 512 MB in your PC (recomended 1GB+)

3. format usb stick to mbr partition with fat32 file system and name it UNRAID (all capital letters is needed)

4. Download unRAID zip file (i have done this with version 4.7)

5. change extension from zip to iso

6. start unetbootini again

7. Chose diskimage (the one you renamed - you dont have to select distribution)

8. Change type to USB drive and select your drive (in my case /dev/disk2s1)*

9. Click on OK

now its building your USB stick, wait while it decompresses file to the USB stick and installs syslinux and makes it bootable

When it says it found some files (menu.c32) and asks to overwrite, just answer YES TO ALL

After its finished, eject your USB stick, insert it in your new "ServerPC" and boot

* how to check what is your dev id for USB Stick on MAC OS X

1. open terminal windows

2. type in diskutil list

3. you will have list of all devices and look for one that is named UNRAID

I Think this would work with Windows, Linux versions also. So if any one has Windows or Linux can you try this and write here if it works there also.

mod edit: corrected the flash drive name as unRAID needs to be all capitals.

Did you actually boot unRaid with the USB drive? I though it had to be named "UNRAID".

I did boot hmm but i named it just unraid i'll change in this guide but i will try and boot with other name also to see if it works

Cool, I have a Mac also, and was looking for instructions on this, but just booted into Windows to create my bootable USB.

this is cool, last time I checked unetbootin did not have an OS X version.  Now that they do this should make it much easier.

I finally got a chance to try this and it does work.  There is some extra steps/trickery that has to be done, but it does work to set up a flash drive on OS X.

I will try updating the wiki tonight when I get home from work.

I finally got around to testing this out and messing with it a little bit.

I will put links in the wiki to these How To's as well as here.

Here is the Windows write-up using unetbootin.

Here is the OS X write-up using unetbootin.

I found the whole process to be pretty straight forward and the fact that I can now create an unRAID USB boot drive from my Mac is great.  I was always using some other machine, or a VM, to make the USB drive.
