Hi,
It's difficult to help without more information:
1. What is your QEMU command-line?
2. What is the partition table on the disk?

General problems with booting Windows are usually caused by a guest
configuration that doesn't match the hardware configuration that Windows
was installed under.  Can you check that the AHCI bus address of the
disk and partition numbering matches what Windows expected?

It may also be useful to enable tracing (see docs/devel/tracing.txt) to
see what the ahci_* trace event log says.  I have CCed John Snow, one of
the few people who can read this log :).
