XP Dual Boot

Hello:

I am trying to configure my PC to dual boot Windows XP Home. My main and
original install is on drive C:\ -- first partition of primary master hard
drive. I copied the install to the first partition of the secondary hard
drive using Partition Magic 7.0. It is logical drive H: in the boot from
Drive C:\. I can read the new XP boot partition and access its files just
fine.

The XP boot loader appears to have found the second copy just fine. Here is
my boot.ini file from Drive C:.

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home
Edition" /fastdetect
multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Microsoft Windows XP Home
Edition (#1)" /fastdetect

If I select the first (original) XP from the boot menu, it boots just fine
as before. But if I select the new drive for boot, I immediately get the
following error message...

Windows could not start because of a computer disk
hardware configuration problem.
Could not read from the selected boot disk.
Check boot path and disk hardware.

I gather I need to change something else in the copied partition to make
this work? Or can I boot XP from the secondary (slave) hard drive?

Any help would be appreciated.

Thanks,
Jess
