HOWTO: Prepare bootable USB disk from ISO image

1) Find out name of USB disk

sudo /sbin/fdisk -l

2) Umount device

umount /dev/sdb1

3) Format drive in FAT32

sudo /sbin/mkdosfs -n 'openSUSE-13.1-NET-x86_64' -I /dev/sdb -F 32

4) Enable ISO recognition by BIOS from hard drive

isohybrid ~/Quellkoden/opensuse/openSUSE-13.1-NET-x86_64.iso

5) Copy ISO file

sudo dd if=~/Quellkoden/opensuse/openSUSE-13.1-NET-x86_64.iso
of=/dev/sdb bs=4k

6) Unplug device correctly

sync
sudo eject /dev/sdb

HOWTO: Prepare bootable Windows 7 USB disk from ISO image

1) Create a new partition and change its type to 7 (HPFS/NTFS/exFAT)

fdisk /dev/sdc, n, p, 1, t, 7, a, 1, w

2) Partition USB drive with parted

sudo parted /dev/sdc

mklabel msdos
mkpart primary ntfs 1 -1
set 1 boot on
quit

3) Format new partition as NTFS

sudo mkfs.ntfs -f /dev/sdc1

4) Install ms-sys

tar xvzf ms-sys-2.3.0.tar.gz
cd ms-sys-2.3.0
sudo make
sudo make install

5) Write Windows 7 MBR to USB

sudo ms-sys -7 /dev/sdc

6) Mount USB drive

mkdir -p /mnt/disk
sudo mount /dev/sdc1 /mnt/disk

7) Mount ISO image file

mkdir -p /mnt/iso
sudo mount -o loop ~/Quellkoden/win/7/en_windows_7_professional_x64_dvd_X15_65805.iso /mnt/iso

8) Copy contents of ISO file to USB drive

cp -av /mnt/iso/* /mnt/disk/.

9) Unmount USB drive and ISO file

sudo umount /mnt/disk
sudo umount /mnt/iso

1) Convert *.iso to *.img using hdiutil

hdiutil convert -format UDRW -o /path/to/target.img /path/to/source.iso

2) Rename *.img.dmg file into *.img

mv <image>.img.dmg <image>.img

3) Get list of currently connected devices

diskutil list

4) Unmount target USB flash disk

diskutil unmountDisk /dev/disk2

5) Copy *.img file to USB flash disk

sudo dd if=<image>.img of=/dev/disk2 bs=1m

6) Eject USB flash disk

diskutil eject /dev/disk2
