I have loaded Ubuntu 9.10 as logical drive extension to my existing Windows 7. The Linux Ext 3 is in a partition 283.6 GB in size and occupies just 6.6 GB. The Linux Swap is 7kB in a partition of 9.3 GB in size.
When I boot up, the Grub shell menu is offered, I select the first Ubuntu option and it boots up OK. I then try and move the cursor, but after a short time period it just freezes.
