## ABOUT

This script will turn your USB-drive into a bootable drive from which you can boot Gentoo Linux.  

I tried running the script supplied in https://wiki.gentoo.org/wiki/LiveUSB/Guide, but I ran into some problems, so I followed the instructions manually, and came up with this.  



I originally intended for this to be run on an Ubuntu machine, which is where I have tested this. However, I believe it's flexible enough to run on any Linux system.  



## Requirements:

You downloaded the Gentoo installation media from https://www.gentoo.org/downloads/ or one of the mirror sites.   

The file should have the file extension `.iso`   

You also have a precompiled Master Boot Record on your computer, it should look something like this: `*mbr.bin`   



You have to run this as root.    



## Usage:

`./gentoo-usb.sh -t TARGET_PARTITION -m MBR_PATH -i ISO_PATH`   

Required flags:   

`-t`: Target partition. Something like `/dev/sdb1`, note that the partition number is required as well.  

`-m`: MBR-binary. The exact path to the precompiled Master Boot Record. For me, it was `/usr/lib/syslinux/mbr/mbr.bin`   

`-i`: ISO-file. Exact path to the ISO image that you downloaded   

Example:   

`./gentoo-usb.sh -t /dev/sdc1 -m /usr/lib/syslinux/mbr/mbr.bin -i /home/alice/Downloads/install-amd64-minimal-20210425T214502Z.iso`    



## WARNING! 

**THIS SCRIPT DELETES ALL DATA ON THE SPECIFIED DRIVE!**    

**NEEDLESS TO SAY, IF YOU ACCIDENTALLY SPECIFY THE WRONG DRIVE, IT WILL DELETE THE DATA THERE AS WELL!**    

**PLEASE USE WITH CAUTION!**
