Using SUSE Studio Image Writer
Install ImageWriter for openSUSE
Install SUSE Imagewriter with 1-Click Install
Or you can use this command as a root to install Imagewriter.
# zypper install imagewriter
Write ISO to USB
Using live-fat-stick (Command line or GUI way)
If you'd rather not reformat the USB device and keep the ability of putting files on it and accessible by other operating systems, you have the option of using the live-fat-stick script from command line or live-usb-gui point and click graphical interface. You can put ISO on vfat partitioned USB stick or hard disk.
On openSUSE you can install the packages via 1-click from here live-fat-stick and live-usb-gui, if you are running any other distribution, get the script from here and make it executable(as root, with
chmod +x /usr/bin/live-fat-stick) after copying it to /usr/bin/, make sure you have syslinux and gpart installed before running it.
Run the following as root (with
su -, not using
sudo) in terminal:
to get the USB device path:
to copy iso to USB device and make it bootable:
it shows help.
Multiple iso images from multiple distributions can be added to the USB device, boot menu will offer a choice of distribution to boot from. Scripts does not format or remove data from the device.
Using commandline tools
Download LiveCD ISO
Download the installation image of your choice from http://software.opensuse.org/.
Verify the integrity of a downloaded image:
$ gpg --recv-keys 9C800ACA
$ wget http://download.opensuse.org/distribution/13.2/iso/openSUSE-13.2-GNOME-Live-x86_64.iso.asc
$ gpg -a openSUSE-13.2-GNOME-Live-x86_64.iso.asc
Find Block Device
After inserting your USB stick, you can find out what device it is:
Write ISO to USB
Finally, once you've found your block device, write the image to it. Point 'dd' to the full path such as '/home/user/Downloads/openSUSE-13.2-GNOME-Live-x86_64.iso' or change directory (example:
cd ./Downloads) to where the image is contained.
# umount /dev/sdX # dd if=/path/to/downloaded.iso of=/dev/sdX bs=4M
How to recover the USB stick for "normal" use again
After system installation, you may want to reuse the stick as you would normally to write things on it. In that case you have to reformat it. Often people complain that Windows fails to do it.
If you look at the 12.3 DVD image on a USB stick with fdisk, you would see something like this (notice the GPT warning):
WARNING: GPT (GUID Partition Table) detected on '/dev/sdX'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sdX: 7742 MB, 7742685184 bytes 64 heads, 32 sectors/track, 7384 cylinders, total 15122432 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x1bf0d4df Device Boot Start End Blocks Id System /dev/sdX1 4248 12439 4096 ef EFI (FAT-12/16/32) /dev/sdX2 * 12440 9162751 4575156 17 Hidden HPFS/NTFS
So, before reformatting, you have to repartition it again. And sometimes, if this fails, you may need an extra step - because software thinks the stick is a CD and thus not writable:
Notice: all these instructions assume the stick device is /dev/sdX. You have to find which is yours (see “Find Block Device” section above). An error here will destroy some other disk in your system.
# umount /dev/sdX # dd if=/dev/zero of=/dev/sdX count=100
That destroys the boot sector, partition table, and initial structures. Any operating system should be happy to reformat it again.
But typically, you would simply start fdisk:
# fdisk /dev/sdX
o create a new empty DOS partition table
n add a new partition
(primary, number 1, default size to use the entire device)
t change a partition's system id
Use type 6, FAT16
w write table to disk and exit
# mkfs.msdos -n SOME_NAME /dev/sdX1
This last step is necessary, specially the -n SOME_NAME, else the stick always mount with the iso name.
And done. Or, you could use gparted for partitioning and formatting.
You could, if you prefer, make a backup image of the stick prior to using it for installation, with dd, and recover it after the installation.
How to make a USB drive bootable
This situation would happen very rarely, but in the event that your computer doesn't boot from the LiveUSB/DVD from the steps above, you might try the following procedure.
Open a console and do the following as root:
# umount /dev/sdX # fdisk /dev/sdX : p «--- print partition table : a «--- activate partition (bootable) : 1 «--- apply to partition 1 : w «--- write changes and exit
