Hello, I hope I am contacting the right adress here or that it, in case I didn't, can get forwarded. I just got an error message from parted that said I found a bug. As I don't know how exactly to check whether it was fixed or not I thought I'll just report it anyway as a bugreport too much is likely better than one too little. I was installing arch linux on a non-efi system and tried to toggle a bootable flag on my boot partition. That failed. Attached pictures of what happened. Feel free to contact me in case you need more details, I'd provide them as good as I can. Have a nice day! - anarchonerd
