Hi, very new to Terminal commands and need a little help executing one. I'm trying to dual boot Ubuntu on my MacBook Pro using a USB device to start the initial boot / installation from. And here's where I got to on the ubuntu website: "Convert the .iso file to .img using the convert option of hdiutil (e.g., hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso)" I'm in Terminal but I'm really not sure what parts of that command to change and what parts to leave alone. I've tried various google searches and variations but I just keep getting errors. Would someone be kind enough to either give me the complete moron's guide to executing this particular command or simply direct me to a free program that converts .iso to .img. I would much prefer a program to do it for me, as I don't want to risk screwing it up. Thanks in advance for help / assistance.
