HELP Needed regarding Dual boot VIsta/Leopard with tboot, NTLDR, chain0

[rohitkpatil]

I had working 10.5.2 with dual boot Windows Vista. I was using windows bootloader with 4 files in C:\ , tboot, boot.ini, NTLDR, chain0.

After upgrading to 10.5.3 and kernel upgrade to 9.3 modbin, it booted inside mac OS,

but when i booted inside vista, and when i again restarted , and i got boot menu option, i selected Leopard, it is not booting inside. Its showing boot menu again, even after repeatative pressing of Leopard, coming back to selection of OS only.

does 10.5.3 changes to different chain0 file ?

please help
