Why isn't Startup Disk Creator working in 12.04?

Solution 1:

There is a alternative way to make StartUPdisk

You need to install UNetbootin. Go to software center and search for it. Then install....

Run it.....from application

You will see this window

• Click on Diskimage.
• Select iso.
• Give 3 GB of space in Space used..... Then select your USB Drive from dropdown menu. Click ok. And wait until finished. Hope it helps.

Solution 2:

I had similar problems on 12.04LTS. My workaround was to launch usb-creator-gtk from the Terminal cli:

• open the Terminal application
• run sudo usb-creator-gtk at the prompt
• inster your login password (I assume you are the admin;) )
• the Startup Disk Creator gui should appear
• try to erase/create the startup disk you need

Solution 3:

Free up your Pen-drive by using Erase Disk button. After finish, there will be an option to set the space that will be used on your pen-drive.

Open Startup Disk Creator

Select Pen-Drive and click Erase button

Click Yes when prompt

Put your password

Wait a lil bit and you will get an option to adjust the extra space.

If it still doesn't work, remove your Pen-Drive and reboot your system.

Solution 4:

I need to test this again but I think if your usb drive isn't configured as "bootable" you'll see this. I could be wrong.

Run Disk Utility and mark partition as bootable.
