I try to install 11.10 on my Asus U30JC laptop. I have 3 partitions. 2 for windows and another Ext3 partition for Ubuntu. I try to install Ubuntu with my USB flash memory. The problem is when you should select the installation partition, it just shows my HDD as a single 500 Gigabyte Unallocated partition. Anyone has any idea what the problem may be?

This shows "sda" as a 500GB HDD, but I see six partitions: sda1, sda2, sda3, sda5, sda6, and sda7 - not the three you mentioned initially. Send the output of this command fdisk -l /dev/sda. –  dan_linder Nov 8 '11 at 18:15
    
Can you add info by editing the original question instead of posing comments. –  mikewhatever Nov 8 '11 at 18:16

Is it possible you chose the "don't overwrite any existing filesystems" option when you're starting the install? (I can't remember the exact name for that option...)

If the Linux partition (/dev/sda6 and /dev/sda7) is not needed, you could try deleting that partition and see if the installer sees the "free" space. Then the installer should see the free space and let you install there.
