Hello altogether,

a couple of weeks ago I updated my linux-system and copied the ISO-Image on an USB-stick so that I can boot it. It did work though, but now I don't have a clue how to format it back to a FAT32-system.

Any idea?

Thank you!

Are you formatting the disk using windows or linux?

if your using windows you should be able to format it by right-clicking on it and click format and select FAT.

Did you format this disk to something like ext3?
did you copy the iso or did you get a distro to create a bootable usb disk for you?

Hi Xlphos.

I copied the iso myself but don't ask me which command I used.

I solved the problem yesterday. I could rewrite the MBR on linux with cfdisk. After that MacOS formated it correctly. That wasn't really a shortcut ^^but it did solve the problem though.

Many thanks
