Dual Boot On Mac Mini Not Working


New Member
I'm trying to get EasyBCD 1.5 to work with Vista RC1 on my Mac Mini. When I try to boot OS X, I get an error message. The code is 0xc0000221 and the message is saying that the computed checksum does not match the checksum in the file header. Here's my configuration:

Windows Boot Manager
identifier {bootmgr}
device partition=C:

Thanks in advance for any help.
Hi dbialac, and welcome to NeoSmart Technologies!

I don't know why you're seeing that error, but it seems that Vista isn't recognizing your efi file.

Can you please try this:
Copy this file from your Mac install
to C:\NST\nst_mac.efi in Windows.

You didn't mention when this error appears.. I assume its after you click "Mac OS X" in the Vista bootloader?

Good luck, let me know if that works.
