I am having some issues with installing Ubuntu on my laptop. I recently reinstalled windows after screwing up the MBR and GRUB. I currently am able to boot into Windows 7 Home Premium and into Backtrack 5 R2. The problem is that neither the ubuntu installer nor gparted can see the individual partitions on my drive. It is all listed as one unallocated space. When I open the "ubuntu explorer" on the live cd I can see the other partitions and can even mount and explore inside of them. I did an fdisk -lu just for kicks and it sees all of the partitions. Here is the output from the fdisk:
root@ubuntu:~# fdisk -lu

sda 1 is the recovery for windows.
sda2 is the windows 7 partition.
sda3 is a data partition for windows.
sda4 is ?.
One if the Linux partitions and the swap partitions must belong to Backtrack.
Any help would be greatly appreciated.
