Install Linux (Debian) from USB stick
To install Debian on a computer/notebook/server, you usually need a CD/DVD drive. Nowadays, however, there is usually no optical drive, so the installation can be started simply from a USB stick. Meanwhile, this is even my favorite method, because the stick is quickly created and more handy than an old-fashioned CD/DVD.
The first step is to get an up-to-date Debian image (9.3). I usually use the amd64 Netinstall image:
root@datenreise:~# wget https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-9.3.0-amd64-netinst.iso
Then we can simply copy the image to a USB stick using dd. (The paths must of course be adapted to local conditions.)
Caution: All data on the USB stick will be lost:
root@datenreise:~# dd if=debian-9.3.0-amd64-netinst.iso of=/dev/sdb 247160768 Bytes (247 MB) kopiert, 33,1076 s, 7,5 MB/s root@datenreise:~# sync
Now you can boot directly from the USB stick and start the Debian installation.
