It's interesting that you say that, as even though Fedora 9's disk utility 
showed the more that 16GB of freespace, create new in the freespace, only 
showed 100MB in the box where you put the size of the new partition. I 
thought that it normally showed the total space available, then you just 
changed it to whatever you wanted.

The fdisk -l /dev/sda output is below, but in the meantime I tried installing 
Kubuntu Hardy Heron 8.04 on the same drive, and had no problems creating 
sda13 for /, and sda14 for /home, as you can see below, and HH is installed 
ok.

And the same for sdb, which is supposed to be just for data, but F9 is also 
there at the mo.

sdb1, and sdb2 have no Win OS on them, and just so that I can store data 
easily from any of the Linux OS's easily, and retrieve it again to whichever 
Linux OS happens to be booted at the time.

Can't login to either KDE or Gnome on F9 though. Firstboot ran on the reboot, 
entered user name, and password, then Firstboot decided to crash. The login 
screen on a reboot shows my realname, and hovering the mouse over it says 
logging in using my user name, which it shows. So I enter the password, but 
nothing from Gnome, just back to the login. Trying a KDE session, it displays 
an error box top left, saying something like "check installation". Anyway 
that problem if I can't fix it is for a new thread.

Thanks for all the replies.

Nigel.
