Ok, it was `sdd', not `sdb'. Now I can boot from the pendrive. The mistake was to do: dd if=debian-7.8.0-i386-netinst.iso of=/dev/sdd1 bs=4M; sync whereas it must be: dd if=debian-7.8.0-i386-netinst.iso of=/dev/sdd bs=4M; sync Thanks to all. But now, one more question: after using the pendrive for the installation, how can I restore it as it was before, to use it to store files?

Is the complaint issued *immediately* after the dd command or some time later? What is the size of the pendrive?

The command dd if=debian-7.8.0-i386-netinst.iso of=/dev/sdb bs=4M; sync , if given as a normal user, gets the `permission denied', and, as superuser, the complain that there's `no space left' on the device.

Why? Some computers contain buggy BIOS versions. Booting from pendrive did not work on my previous 32-bit PC either, even though the BIOS was set to do so. Fortunately, it does on my new 64-bit PC. If it does not work in your PC (did booting from pendrive _ever_ work with it?), then there are still a couple of other options you can try, as described here (section 3.6.2, last two paragraphs): www.debian.org/releases/stable/i386/ch03s06.html.en#boot-dev-select -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

Why? Assuming the machine can boot from USB, check the BIOS settings again.
