Boot issue

[embedded123]

Hi

 

I'm trying to dual boot mac os x 10.5.7 with win7.

I was trying to install cham rc2 on my mac os.

 

I did some mistake by executing this command:

fdisk -f boot0 -u -y /dev/rdisk0

 

and I can not boot neither Win7 nor mac os x.

I think the system tries to boot from the wrong partition.

 

How do I resolve this issue?

 

Thanks

 

Edit:I solved it, just set the right partition as active
