Joseph, I am assuming you are trying to create an install disk? If so, you shouldn't have to do all these steps. I normally just download the minimal install ISO and write it to a USB drive with the following commands: # dd if=/path/to/minimal-install.iso of=/path/to/usb-drive bs=4096 # sync You don't have to mount the USB drive. Use sync to ensure that all the data has actually been written to the device before you remove it. I have run across problems with some ISO files that don't play nice with this method, but this one seems to work well with the Gentoo minimal CD. Also, keep in mind that you don't really need to have the Gentoo install disc to install Gentoo. It's certainly EASIER to follow the handbook when you have the minimal install disc, but just about any Linux live CD will work as long as the architecture matches (chroot from x86 to amd64, for example, will not work). Anyway, if this is not what you are trying to do, maybe you can give us more details. -- Will Tomlinson

There's actually instructions for non-Gentoo installation media: https://wiki.gentoo.org/wiki/Installation_alternatives Specifically, there can be some issues with setting up the shell environment from some environments. -- wraeth signature.asc Description: This is a digitally signed message part.

Surely you don't mean an actual USB stick with 1MB capacity...? dd if=/path/to/minimal-install.iso of=/path/to/usb-drive bs=4096 sync I think the dd will work with LiveDVD but not liveCD. What path are you using for the USB drive? Are you specifying a partition (which you shouldn't)? As a working example: dd if=/home/wraeth/iso/install-amd64-minimal-20140529.iso of=/dev/sdc bs=4M sync -- wraeth signature.asc Description: This is a digitally signed message part.
