Make bootable USB

Make partitions

   # fdisk -l /dev/sdb  
   
   Disk /dev/sdb: 8422 MB, 8422162432 bytes
   239 heads, 47 sectors/track, 1464 cylinders, total 16449536 sectors
   Units = sectors of 1 * 512 = 512 bytes
   Sector size (logical/physical): 512 bytes / 512 bytes
   I/O size (minimum/optimal): 512 bytes / 512 bytes

Download Gentoo LiveCD iso

Go to http://www.gentoo.org/main/en/where.xml ; pick mirror you like and download install-amd64-minimal-[0-9]*.iso, for example - this one:

   wget http://distfiles.gentoo.org/releases/amd64/autobuilds/current-iso/install-amd64-minimal-20120621.iso

Mount gentoo LiveCD

   # mkdir -p /mnt/cdrom/
   # mount -o loop install-amd64-minimal-20120621.iso /mnt/cdrom/
   mount: warning: /mnt/cdrom/ seems to be mounted read-only.

Mount usb stick

   # mkdir -p /mnt/usb/
   # mount /dev/sdb1 /mnt/usb/

Copy contents of LiveCD to usb stick

   # cp -aR /mnt/cdrom/* /mnt/usb/
   # mv /mnt/usb/isolinux/* /mnt/usb
   # mv /mnt/usb/isolinux.cfg /mnt/usb/syslinux.cfg
   # rm -rf /mnt/usb/isolinux*
   # mv /mnt/usb/memtest86 /mnt/usb/memtest
   # sed -i \
        -e "s:cdroot:cdroot slowusb:" \
        -e "s:kernel memtest86:kernel memtest:" \
        /mnt/usb/syslinux.cfg

Unmount medias

   # umount /mnt/cdrom/
   # umount /mnt/usb/

Install syslinux

   note guide # syslinux /dev/sdb1 

Boot from USB-stick

If in trouble, try following gentoo handbook

Install Funtoo

Once booted, do this:

Partition hard drive

   # gdisk -l /dev/sda  
   GPT fdisk (gdisk) version 0.8.4
   
   Partition table scan:
     MBR: protective
     BSD: not present
     APM: not present
     GPT: present
   
   Found valid GPT with protective MBR; using GPT.
   Disk /dev/sda: 1953525168 sectors, 931.5 GiB
   Logical sector size: 512 bytes
