I don't think it's relevant to me personally but it may be relevant to people who have a Mac of that age and may come across those particular problems, maybe.

I don't have the knowledge for extensive testing, just some anecdotal evidence: I took the Sandisk Cruzer that I had prepared following Quackers' great tutorial, wiped the content and used unetbootin under linux to install a different linux system (xubuntu 13.04). The drive booted both my MacBook and a Lenovo Thinkpad. So the information might be not 100 % accurate.
That's good to know. Thanks pindar.

Thank you for your effort and your information, i followed your guide but i didn't manage to make a functional live-usb. This are my information:
OS: Mac OS X 10.6.8
Hardware: Mac Mini 3,1
Ubuntu ISO version: ubuntu-13.04-desktop-amd64+mac
syslinux version: 6.01
usb pen drive: Corsair 8gb
I tried the following:
1. format and partition the flash drive with MBR (disk utility -> options) and use:
1.1 /syslinux-6.01/bios/mbr/mbr.bin/
1.2 /syslinux-6.01/efi32/mbr/mbr.bin/
1.3 /syslinux-6.01/efi64/mbr/mbr.bin/
2. with GUID:
2.1 /syslinux-6.01/bios/mbr/mbr.bin/
2.2 /syslinux-6.01/efi32/mbr/mbr.bin/
2.3 /syslinux-6.01/efi64/mbr/mbr.bin/
"Boot Error" was the result and of course after each of these 6 "experimentations" re-format the flash drive and follow step-by-step your instructions, always checking if the flash-drive was mounted.
Also, the command:never worked for me, instead i used:Code:diskutil unmount /dev/diskX
If you could provide me with any insights/suggestions/directions i'm happy to test themCode:diskutil unmountDisk /dev/diskX
ps: I even replaced the rEFIt program i used with the rEFInd that you used, so i could reduce the possible errors/problems.
ps2: all 3 mbr.bin files seems to contain the same (bytecode?) text, so i assume that it doesn't make any difference which one anyone choose.

sthrss, you're right about the unmount command. I suspect I've chopped the end off whilst editing. Thanks I've edited that.
Just for clarification you need to cd to syslinux-6/bios/mbr then run the command (not to /syslinux-6.01/bios/mbr/mbr.bin/)
I would have expected your command to give an error message. Was that the case?
You're probably better off with rEFInd than with rEFIt as that's not maintained any more.

Thank you for your quick reply and info! Yes, you're right about the folder i actually run (each time reformating my flash drive and repeating your steps from the beginning):
which is the same. My system didn't gave more errors than those that you've mentioned at your 1st post, the ones you've ignored.Code:1st time: sudo dd conv=notrunc bs=440 count=1 if=/Users/sthrss/Downloads/syslinux-6.01/bios/mbr/mbr.bin of=/dev/disk1 2nd time: sudo dd conv=notrunc bs=440 count=1 if=/Users/sthrss/Downloads/syslinux-6.01/efi64/mbr/mbr.bin of=/dev/disk1 3rd time: sudo dd conv=notrunc bs=440 count=1 if=/Users/sthrss/Downloads/syslinux-6.01/efi32/mbr/mbr.bin of=/dev/disk1

Hi, just checking but does your Mac boot from a flash drive? It has that capability? Some don't.
Secondly do you have a different kind of flash drive to try? I have read that some types of flash drive may not have EFI drivers available which could be a problem.
I can think of no reason why it shouldn't work other than the above.
It's really the same thing but a different way to go about it but if you copy or move the Syslinux folder to your user's home directory it makes it a lot easier to cd to it. You can then try to run the commands as posted.
However, if you aren't getting any errors when entering the commands I can't explain why it isn't working.

After a long series of tests (lol) i managed to make it work!
0. GUID partitioning of usb
1. follow all the steps from your guide except the unebootin part.
2. sudo dd if=/path/to/downloaded.isoof=/dev/diskN bs=1m
I read that the "r" in front of disk is like a parameter for faster copy, so i just preferred the "simple and safer" method; silly thought but it might did the trick.
Then mac os x returned a window with an error message, something that my device is not recognised and i ignored it. Reboot and voila! the usb worked!
BUT after the first steps of installation the partition i wanted to use (my hdd was already partitioned, 1 mac os x, 1 16gb for linux and 1 2,1gb for swap), was already in use by /cdrom, i couldn't unmount it by any means, so i opened the partition it was mount [/dev/sda5 -> the one i want to use for the installation] and found that it contained data from the usb, i returned to mac os, reformat them [/dev/sda5; /dev/sda6 -> swap] in ntfs (just in case ubuntu mounts the usb to any free fat32 -like the usb's fs- partition), reboot and the installation run smoothly...
... after the final -thought to be- reboot, i tryied to load the new ubuntu installation but efi returned this message:
No bootable device - insert boot disk and press any key
I'm really exhausted with the situation and the worst part is that i don't have 2nd computer, the cdrom driver is broken and i really need a linux distro in my stupid-for-buying-it-because-it-was-on-discount-offer, old mac mini...
If you have any thoughts/directions/info on how i should proceed i'm happy to follow, because right now i'm really puzzled and confused on what to do, thanks in advance
PS: Suddenly now i have no boot options (just boot directly to the mac os), tried to reinstall rEFInd but it didn't help, also i cant reformat the partition were i made the installation nor the swap; when i used "disk utility.app" to erase (format) the partitions, it returned:
Volume Erase failed with the error:
Could not modify partition map
