- Using dd to write the ISO contents directly to the USB absolutely does not work. - Using any other method to copy the ISO contents also doesn't work.

Both are true for any distribution of Linux. The core problem is that how an ISO is converted into bootable USB is not the same from one distribution to another. The best option is unetbootin: Unetbootin is an automated tool that will take many different ISOs (it isn't guaranteed to work if you use it with an ISO that isn't on its approved list, though, so you might want to check the compatibility first) and makes bootable flash drives off them. But there is no OS X version of it, AFAIK, so the USB must be created using unetbootin in a Windows or Linux environment. If that's not a possibility, you can use OS X, and follow tutorials appropriate to your distribution, such as the ones at pendrivelinux.com, but you'll have to find an alternative way to put a bootable MBR on it and syslinux it.

Button and locate the ISO file. Make sure the destination disk is the USB thumb drive you've inserted. Click Continue. It can take about 20 minutes to format and set up the USB installer on the Mac. Solution 2: Burn ISO to USB hard drive. Besides the abovementioned solution to copy ISO to USB drive through direct copy-and-paste, for burning ISO to USB hard drive of external DVD/Blu-ray recorders, you could make use of some 3rd-party ISO burner programs.

(FWIW, I know I've done this at least once -- it's even possible to make a bootable USB of an Intel Linux distribution purely from a PPC Mac. I had to do this because I inadvertently completely jacked the Ubuntu installation on my Eee to the point that I could not recover, and I didn't happen to have a working bootable flash drive for it at that moment). Since Unetbootin came out, I pretty much avoid any other method if at all possible. 'but you'll have to find an alternative way to put a bootable MBR on it' I'm using Mac OS X 10.4.11 on an iBook G4 and in Disk Utility under the Partition tab, if you click options, there is a choice of partitions scheme, you can choose Master Boot Record (MBR) 'To use the disk to start up DOS and Windows computers' Things are easy on a Mac To get around the 'busy' thing when using dd: In Disk Utility: Unmount the volume of the usb drive, not the drive itself. I recently used this to put an.img of Ubuntu Netbook Remix on a usb flash drive following Only change I had to make was to use 'bs=1024' instead of 'bs=1M' for the blocksize argument in dd And you can get the /dev/disk? Number from Disk Utility too, select drive and press apple+i.

I've been reading forums all over to try to create a bootable USB version of slax with my Macbook. I'm running 10.5.8. Up to this point I have a configured USB with a FAT32 partition and I have both the slax-6.1.2 iso and the raw files extracted from the slax-6.1.2.tar. I have followed the previous advice about 'burning' the iso to the USB with the disk utility trying the iso and the mounted volume of the iso. I keep getting the same failure: 'Restore Failure Could not validate source - error 254' even with the mounted volume as the source. Am I missing a step?

Also, I'm not very experienced with command line interface, but i've tried running the bootinst.sh in the USB but I get an error like this: egrep: /proc/mounts: No such file or directory egrep: /proc/mounts: No such file or directory egrep: /proc/mounts: No such file or directory Can't find device to install to. Make sure you run this script from a mounted device. Any advice would be greatly appreciated thanks! I've been reading forums all over to try to create a bootable USB version of slax with my Macbook.

I'm 99% sure the error 254 indicates an incorrect drive format/partition type. I've noticed that whenever i get that error, if i click 'info' for the disk image, it is of a format that i can't apply using disk utility. It will be like iso 9886 or UDF, while i can only choose HFS+, FAT, etc. There is a program called macFUSE that can deal with extra format types -- and i hate to be another a**hole to post without a solution, but i would try looking into using macFUSE to give OS X the ability to deal with those formats, then maybe you'll be able to partition your media to the appropriate file system to match the source image. Personally, i boot into windows and use unetbootin to make linux discs.
