I have the Windows 7 iso and I wanted to make a bootable flash drive out of it. I used to use Unetbootin but they have now removed the option to show all drives. Can anyone suggest another program that can make a bootable flash drive?
As recommended in step 2 of the simple Ubuntu download and installation instructions (click USB stick, click Windows, then click Show me how), you can use the Universal USB Installer to write .iso images (including Ubuntu .iso images) to USB flash drives.
Microsoft maintains some Windows 7 specific instructions for creating a bootable Windows flash drive. If the above suggestion doesn't help, perhaps those will. (I cannot watch that video--I have Moonlight, but I'm still not able to watch that Silverlight video. But you're interested in doing this from Windows, and you can probably watch that video from Windows. As I commented, I do wonder if this is on-topic for AskUbuntu...)
Using gparted format the drive NTFS, set the boot flag.
Using Archive Manager extract the iso to the drive.
(or just copy the DVD to the drive).
