Problems after changes with Partition Magic 7

[hysterio]

Hi,

I have a pc with Windows XP SP2 and a 120GB SATA HDD. This drive contains already a lot of information and data on it. Yesterday i wanted to partition in several smaller pieces with Partition Magic 7.0 so i used the wizards to add some new partitions. No problems so far. When i click on "apply changes" it's telling me to restart my pc so changes can be made, so pc reboots and PM7 does his job. It went really slow, so i did see some tv. When i came back PM7 says error has accoured (some attribute is missing) and will now reboot if i hit any key.

Problem: pc keeps rebooting and when i want to reboot from pc and i want to install new operating system it says it can't find any drive! So what can i do now? is there any possibility that i can recover the data on this drive?

Any help and suggestions are appreciated
Thanks anyway!

Repartition drive. Restore from backup.
