These instructions (https://www.ubuntu.com/download/desktop/create-a-usb-stick-on-ubuntu) doesn't work for Ubuntu Server iso. Doing dd if=ubuntuserver.iso of=/dev/sdb doesn't work either. In both situations, after the Ubuntu Server installer boots correctly, it says it hasn't found any CD drive and stops.

I've a USB stick where I've put the content of Ubuntu Server iso on it. I've configured Syslinux (with no APPEND parameter) pointing to vmlinuz+initrd present in "install" folder. The installer boots correctly but it hangs with an error saying it doesn't find the CD-ROM.

If I replace the vmlinuz+initrd with the "hd-media" ones (available here) I get another error: installer can't find any iso file anywhere (which is logical because I don't have any iso, I have the expanded tree on sdb1).

So I can't boot Ubuntu Server 16.04 from a USB stick.

  • Thanks, but with Ubuntu minimal CD the packages must be downloaded from a remote server. I don't want to have any network infrastructure: I just want to insert the Usb, install Ubuntu and nothing more.

  • I finally solved using a Fedora Server iso :-(

  • Thanks. In my case, I ended up using an actual CDROM instead of a USB.

Cloning the current Ubuntu Server 16.04.1 LTS iso files with dd works for me. But I use mkusb or mkusb-nox to wrap a safety belt around that powerful but dangerous dd tool.

  • Maybe the original 16.04 version is bad. But 16.04.1 (the first point release) is debugged and polished.

  • Maybe your download {was/is/will be} bad. Please check the md5sum (or get a new copy via torrent, that checks the md5sum automatically).

If you want an installed system in your USB stick, I suggest that you try according to the following link,

Installation/UEFI-and-BIOS
