Typical process of creating a bootable USB using previously downloaded ISO image file is pretty easy but with Debian it can become a bit tricky. Follow this article to ensure your startup disk is created in a correct way.
In my case using Startup Disk Creator led to see an unpleasant exception in my terminal.
An uncaught exception was raised: Invalid version string 'GNU/Linux'
Let's see how we can solve this issue and end up with a fully bootable USB with Debian 7.4.0.
Preparation of the Image
Find any USB drive you want to use that has enough free space. Mount it and check on which
/dev/sd* Linux recognizes it. In my case once it was
sdb and second time it was
sdc. Now obtain the path where the Debian ISO file is located. Mine sits at:
Your location (as well as the name of the home directory) will be obviosly different. Change it accordingly.
Creation of the Startup Disk
Open terminal and type:
sudo dd if=[path_to_iso] of=[path_to_usb]
sudo dd if=/home/slick/Downloads/debian-7.4.0-amd64-CD-1.iso of=/dev/sdb
Do not provide a path to the exact partition, like
/dev/sdb1. If you do that, your bootable USB won't work! In case you are wondering what
dd command does, in a brief explaination it copies whole ISO content as raw data into your USB.
After a minute or two, you should see something similar to:
1275904+0 records in 1275904+0 records out 653262848 bytes (653 MB) copied, 17,4742 s, 37,4 MB/s
Your bootable USB with Debian is ready to go.
