Ubuntu – I can’t create bootable USB drive with Startup Disk Creator

11.04startupusb

After re-installation of Natty, I had lost ability to create bootable USB drive with Startup Disk Creator.

When I tried to add an .iso image into (through the button Other), nothing happend.

Disk Creator won't add the source CD image.

Startup Disk Creator Image

I have tried to re-install Startup Disk Creator, but it doesn't help.

I have read that a 2GB flash drive is now minimum for a Live install. I have not confirmed this.

Alternatly you can boot the 712 MB Ubuntu iso image using grub2. MultiBootUSB has script for doing this.

You could always do this the command line way.

Unmount the drive first

sudo umount /dev/sdb1

then you'll need to use DD to write your ISO to the drive:

sudo dd if=/path/to/file.iso of=/dev/sdb bs=1M

be sure to get the correct path, and change sdb to whatever your external drive is mounted as.

Your device is mounted. Your OS is using it, so it will not work correctly.

Also, you need to dd to a "/dev/xda" device, and not a mount point.

You will need to run:

sudo umount /media/felixinx/0392-8145

Then, run

blkid

to find out the device, maybe it will be /dev/sdb, so run:

sudo dd if=ChromeOS.img of=/dev/sdb bs=4M

Should work, if not, post the result. If you cannot unmount, just reboot, and don't open the file manager.
