I am trying to install Sayayon on an Acer C720 Chromebook.
I downloaded Sabayon_Linux_14.01_amd64_KDE.iso and
used unetbootin to make a bootable live usb stick.
I followed the Chrubuntu guide on how to dual boot linux on the Acer C720:

In developer mode I ran the installation script 9sgchs which
shrunk the ChromeOS artition down to 12G leaving 103G for Linux on my 128G M.2 (NGFF) mSSD.
After successfully rebooting, the reparitioning all went well.
So I stopped at Step #7 before installing the Chrubuntu OS in order to install Sabayon.
Pressing Ctrl-L for Legacy SeaBIOS mode, I got the SeaBIOS prompt to boot from either my SSD or pendrive.
So I chose the Sabayon liveusb pendrive, and at the Anaconda Menu chose to boot KDE,
pressed "tab" to edit the kernel commandline and added "mem=1536m" and then booted.
KDE loaded with everything working (except for the trackpad)
which I knew needed patching to work from IntelMiner's blog on installing Gentoo on the Acer C720:

I ran the Anaconda and installed LVM on top of /dev/sda7 with 3 logical volumes:
root / 30G
boot / 500M
home / 50G (encrypted with passphrase)
free ~ 32G of unused LVM space for future use
After completing successfully I then rebooted
and at the SeaBIOS prompt selected booting from my new Sabayon partition,
then the bootloader hangs:
Decompressing Linux... Parsing ELF...Performing relocations... done.
Booting the kernel.
So I rebooted from the Sabayon liveusb pendrive to try repairing the bootloader by adding the
mem=1536m kernel commandline option to /boot/grub/grub.cfg (as well as in /etc/default/grub)
I originally had /boot formatted as ext2, but Anaconda said it could migrate that to a better format,
so I said OK. (All it did was just change from ext2 to ext3). The next time running Anaconda
bootloader repair it said that the /boot was ext3 which didn't match fstab and so it then aborted

So I just edited /etc/fstab to change /boot to ext3 and reran the bootloader repair. This time all
went well.
But after rebooting, SeaBIOS hangs at the same spot.
Thanks for any ideas on getting Sabayon booting from the SSD and not just the pendrive.
