Thanks guys, at least I'm getting replies now!
OK, I've simplified things now.
I have Windows 7 on 1st drive (ignore other partitions), and OSx86 on 2nd drive.
I have the dual Windows 7 and Mac OS set by EasyBCD on the 1st drive.
So, what happens is:
1) on boot, I get the first menu 'Windows Boot Manager' a) Windows 7 or b) Mac OS.
2) selecting b) then takes me to another screen that says (amongst other things) 'Boot Device 0x80... Press a key within 2 secs to change boot drive'. So I then select 81 for the drive that OSx86 is installed on.
3) then I have 'Darwin /x86 boot v5.0.132 - Chameleon v1.0.12' menu and I select 'hd(1.1) Mac OS' and Leopard boots up perfectly.
I have tried to install Chameleon RC1 and RC2 from the download install files, but nothing changes.
Can you give me any more help?
Thanks.
BTW, I tried searching a lot to find a similar problem without success.
