Sda2 never mounts during installation

[eoghainam]

I'm trying to install sabayon 9. The installer gets to the point where it says its mounting sda2 and never moves on (sda2 is an extended file system according to gparted). Ubuntu has been installed in the same place before and never had this problem except when you tried to use the recovery mode or one of the options in gparted. Any ideas if this is fixable?

Not enough info. Boot the Sabayon CD, open a terminal and as root user (su -) enter the command: fdisk -l(lower case Letter L in the command) to get your partition info or else post the partition info from gparted. If it is an Extended partition, there is nothing on it. Extended partitions are containers for logical partitions which can contain data. Not sure I am reading your situation correctly but if you post the output, someone should be able to help. Do you have any other operating systems installed?

From ubuntu couldn't get a terminal using the sabayon usb.

sda1 has windows xp
sda5 has more windows xp (both these and sda2 are how the laptops instalation disk set it up I then shrank sda5 to install linux)
sda6 is where I would be installing sabayon if I could get that far
sda7 is ubuntu

I insert the usb it, turn the computer on, I type install (or sabayon, they both have the same problem), I press alt-f1 to get verbose mode.
I then get to this screen:

and it goes no further (having left it for half an hour)

The pertinent message is "looking for the cdrom". It can't find the filesystem on the usb.

I type install (or sabayon, they both have the same problem),

I haven't installed the most recent Sabayon. The last time I did, I booted the CD and got to a Desktop with an install icon. How did you create the usb? Have you tried it on another computer to see if it boots? Do you have the usb set to frist boot priority in the BIOS?

The link below has step-by-step instructions for installing Sabayon. It's not for the latest version but is pretty much what you can expect to see:
