I downloaded the 64 bit iso image and ran checksum
Md5 shows identical check sums
Ran isohybrid
used fdisk to mark partition as bootable as given in SUSE instructions
Have brand new ASUS motherboard with usb capability bios is set for allowing re-moveable drive boot
Any ideas?
Thanks for any help I can get
How did you copy the iso to the usb?
You cannot just mount the USB, then copy as a file.
I leave the USB unmounted, and copy with “dd_rescue”
as in
# dd_rescue openSUSE-12.2-DVD-x86_64.iso /dev/sdf
My USB devices shows up as “/dev/sdf”, which I check with
# fdisk -l /dev/sdf
This is the way I do it, assuming it’s on my laptop, with /dev/sdb being the USB medium
cd TO_FOLDER_WHERE_DVD_ISO_LIVES
isohybrid openSUSE-12.2-DVD-x86_64.iso
dd if=openSUSE-12.2-DVD-x86_64.iso of=/dev/sdb bs=4M
I used imagewriter for this, download from SUSEStudio 12.1 repo.
Not sure if 12.2 version is up, but this (32)](http://download.opensuse.org/repositories/SUSE:/SUSEStudio/openSUSE_12.1/i586/imagewriter-1.9-4.1.i586.rpm)(64)](http://download.opensuse.org/repositories/SUSE:/SUSEStudio/openSUSE_12.1/x86_64/imagewriter-1.9-4.1.x86_64.rpm) should work fine.
Sorry, I left out a step

USB drive was not formatted in FAT32
From what I read it needs formatted in FAT 32 to use the procedure that I am using?
Why not use a bash script that does all of the work for you?
S.C.L.U. - SuSE Create Live USB - Version 1.12 - Blogs - openSUSE Forums
openSUSE 12.2 iso download links have just been added to 12.1 included in the script.
Thank You,
Once you have written the ISO to the USB drive, it will be formatted to the file system of the ISO.
Looking at my USB for a successful 64 bit install,
fdisk -l /dev/sdf gives:
Disk /dev/sdf: 8004 MB, 8004304896 bytes
64 heads, 32 sectors/track, 7633 cylinders, total 15633408 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: 0x44e5d832
Device Boot Start End Blocks Id System
/dev/sdf1 * 0 9119743 4559872 17 Hidden HPFS/NTFS
so that shows the partition type ID as hidden NTFS.
When I run “blkid”, the line for the USB shows:
/dev/sdf1: LABEL="openSUSE-DVD-x86_640167" TYPE="iso9660"
so it actually has the file system iso9660 (or the filesystem used for CD and DVD).
Disk /dev/sdb: 7739 MB, 7739768832 bytes
64 heads, 32 sectors/track, 7381 cylinders

nrickert thank you but
My output is shown above. It is almost identical to yours. So why won’t mine boot?
I used dd and my live USB 12.2 DVD worked fine.
OK Problem solved. Did not have usb drive as first hard drive pointed to in bios. Thank you all for your responses.
Try the reverse and run isohybrid on the .iso file, then use imagewrite to make the usb.
When you run isohybrid on the iso file, it will output a warning about some bios’ not being able to boot the image due to its size. It’s ok to proceed and ignore that error.
All the previous suggestions above are great and provide you with many options.
In a nutshell, here is what I always do and it hasn’t failed for me yet. Note that that will erase the usb drive completely so backup any files if needed.
Do everything below as root:
su -
1.) Find which device your USB is assigned to.
fdisk -l
I’ll say mine is /dev/sdx
2.) Create a new partition table and a new partition on the usb drive:
fdisk /dev/sdx
press ‘o’ on your keyboard, this makes the new partition table
press ‘n’ on your keyboard and just keep pressing to accept the defaults, this makes the new partition.
press ‘w’ to make the changes final and it will exit fdisk.
3.) Use dd:
dd if=openSUSE-12.2-DVD-x86_64.iso of=/dev/sdx bs=4M
#Notice that the “of=” goes to /dev/sdx and not /dev/sdx1.
4.) Check to make sure it is bootable, it should be:
Disk /dev/sdx: 16.0 GB, 16049504256 bytes
64 heads, 32 sectors/track, 15306 cylinders, total 31346688 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: 0x44e5d832
Device Boot Start End Blocks Id System
/dev/sdx1 ***** 0 9119743 4559872 17 Hidden HPFS/NTFS
Look for the asterisk in the Boot column
When you reboot, select the “Installation” option, but before you enter it, place these into the boot parameter box near the bottom of the window.
namescheme=by-label kiwi_hybridpersistent=yes
Note that the kiwi option is optional. What that does is take the space on the USB that the DVD didn’t use and converts it into a usable linux partition to store files. The DVD will use around 4.7GB so if your USB is larger than that and you want to use the extra space as storage, then go ahead and use the kiwi option.

saultdon, thanks for all the details above. That let me successfully create and use a bootable USB stick as installation medium. I used the DVD iso for 32-bit OpenSuSE 12.3 milestone 1. I wanted to learn how to use a USB stick instead of burning a DVD for each development release.
I followed your steps 1 and 2, and ran isohybrid on the .iso file, then used SuSE Studio imagewriter to make the usb. I had used the dd procedure of your step 3 in one of my earlier attempts, and it seemed very slow. Imagewriter seemed faster at writing the iso. I have no data to back up these statements, it’s just my perception.
Your advice to put “namescheme=by-label” into the boot parameter box got me over the final hurdle.The installation went well from that point.
Regards,
Howard
I don’t know how to add that repository to my list. I’ve only ever had to do that twice and I had the specific entry spelled out for me. Thanks any way.
