SO A INSTALAR: LINUX

A traves de consola

Download the desired file Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight)

Convert the .iso file to .img using the convert option of hdiutil

hdiutil convert /path/to/ubuntu.iso -format UDRW -o /path/to/target.img Note: OS X tends to put the .dmg ending on the output file automatically. Run

diskutil list to get the current list of devices Insert your flash media Run

diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2) Run

diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2)

If you see the error "Unmount of diskN failed: at least one volume could not be unmounted", start Disk Utility.app and unmount the volume (don't eject).

Execute

sudo dd if=/path/to/downloaded.img of=/dev/diskN bs=1m (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img or ./ubuntu.dmg). Using /dev/rdisk instead of /dev/disk may be faster.

If you see the error dd: Invalid number '1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M.

If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in use. Start Disk Utility.app and unmount the volume (don't eject).

Run

diskutil eject /dev/diskN and remove your flash media when the command completes Restart your Mac and press alt while the Mac is restarting to choose the USB-Stick

Open a Terminal (under Utilities)

Run diskutil list and determine the device node assigned to your flash media (e.g., /dev/disk2)

Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2)

Execute sudo dd if=/path/to/downloaded.iso of=/dev/diskN bs=1m (replace /path/to/downloaded.iso with the path where the image file is located; for example, ./windows7.iso)

Run diskutil eject /dev/diskN, and remove your flash media when the command completes (this can take a few hours on slower drives)
