Hi! I was wondering what the difference is between img and iso file extensions. I was trying to install the UNR of 9.10 but was not getting an img file to write into my USB stick so downloaded the iso file and wrote it to my usb using dd. But my laptop does not boot from the USB. Am I missing some thing that needs to be done?
My command to write the iso image - #dd if=Ubuntu-NR.iso of=/dev/sdb bs=1M Ubuntu has a usb image writer program that writes img files into the USB stick. But operates only on img extensions. It uses the command #dd if=Ubuntu-8.10.img of=/dev/sdb bs=1M Does iso and img files differ fundamentally that these commands on iso format does not work? -- Navneet Thillaisthanam
