Partitions Gone!

Hi All. I had 3 partitions with one of them running Kalyway perfectly. I tried to install iDeneb on one of the partitions because I wanted to update to 10.5.5. After the installation I got the error HFS+ Partition Error. I tried to fix it using fdisk and information from http://forum.insanelymac.com/index.p...t=#entry604741
But now I get Boot0: MBR, Boot0: done, boot1: error
If I run Disk Utility from the iDeneb installation disk I don't see any of my partitions any more!
fdisk still shows 4 partitions with AF id for the first and 00 for the others.
Any suggestions? Will I be able to get my data from my old Kalyway installation? Any help will be much appreciated.
