Dual Boot 7 & OSX - Device Timeout

[SMUJeremy]

Here is my setup:

3 ACHI Sata Drives

Port 0 - 750GB - Windows 7

Port 1 - 250GB - OSX

Port 2 - 250GB - Backup/No OS

 

I have gave up trying to get the Windows 7 bootloader to load Darwin so I am attempting to use the OSX drive first and use Darwin to load either OSX or Win 7 but when I boot from the OSX disk when the Win 7 disk is plugged up I get EBIOS read error: Device timeout Block xxx Sector 0. If I only have the OSX disk installed then it will boot just fine. After about 5 minutes of timeouts, then it goes into Darwin and lets me choose which disk to boot into. I mostly installed using TonyOSX86 ... have PC EFI 10.6 installed and just tried to upgrade to the latest Chameleon - no change.

 

Edit: I would prefer to use my windows drive to give me the option rather than the OSX drive.

I think I have it figured out now. I played around with my hard disks. My 250gb drive that is a backup drive must be on it's way out because when it is not present I have no issues getting Chameleon to pull up instantly and then select which drive to go into.

and select STARTUP REPAIR

and then after its completed,u should boot into windows 7(TAKE OUT UR WINDOWS 7 CD)now download easyBCD 1.7.2

after that go to the tab ADD/REMOVE ENTRIES

and select mac and in the drop down list select GENERIC x86 PC

and give a entry name,it should appear in you windows 7 bootloader

reboot ur system u should see two entries

windows 7 EDITION NAME(RECOVERED)

NST MAC OSX(or whatever u named it)

select NST MAC OSX and it should take u to Chameleon,let the load bar finish or press any key for boot options and den boot how u want to into mac osx

None of the EasyBCD things work for me. If I try to use MBR I get a Chain Boot Error and if I try EFI I get the Grub prompt.

This fixed it for me:

I used that chain0 file and renamed it nst_mac.mbr and replaced the EasyBCD file.
