after installing "ubuntu" lost the partitions that were earlier there in the system

I had Win xp and fedora core 6 in my system earlier.
Then I installed ubuntu . Before the installation of ubuntu my partition table was like this -

/dev/sda file system size used
/dev/sda1 fat 32 30005 Mb 23027 Mb
/dev/sda5 fat 32 30005 Mb 23626 Mb
/dev/sda6 fat 32 10001 Mb unknown
/dev/sda7 ext 3 106 Mb 14 Mb
/dev/sda 8 swap 1258 Mb 0 Mb
/dev/sda 9 8644 Mb unknown

While I was installing ubuntu it said
the following partitions are going to be formatted
But after the install i can't find my /dev/sda5, /dev/sda6 & /dev/sda9
Now i have my important data in them & i didn't even take the back up of it under the pretext that only the above mentioned 3 partitions are being formatted . Now what shall i do ?
Please help ? I badly need your help ! Thank You!

I assume you have only the one hard drive in your PC. The partitions may still exist but entries for them may not have been written into Ubuntu's /etc/fstab file. To determine if the partitions exist, boot into Ubuntu and open up a terminal (Applications | Accessories | Terminal). Now enter the command "sudo fdisk -l /dev/sda" and press Enter. After typing in your user password and pressing Enter, you will get a list of all the partitions on the hard drive. Assuming you see all the original partitions (sda[1,5-9]), you'll need to look at the fstab file to see if there are entries for sda5, 6, and 9. If there are none, you'll need to figure out a place where they should mount (e.g. /windows/D, .../E, .../F) and add entries for them to fstab (hint: partition UUIDs are under /dev/disk/by-uuid/). The existing entries can guide you.

If the partitions do not exist or have been overwritten, then recovery is more complicated. The earlier-mentioned link is probably as good a place to start as any. Good luck!
