Triple boot machine can't find Windows partition

[nipponese]

Hi, I having some trouble getting Parallels to find my Windows partition.

After editing My Boot Camp.pvs to the following, Parallels just throws out an "There is no operating system installed in the virtual machine" error.

[IDE devices]
Disk 0:0 enabled = 1
Disk 0:0 = 1
Disk 0:0 media = 1
Disk 0:0 connected = 1
Disk 0:0 image = Boot Camp;disk0s4
Disk 0:0 cylinders = 0
Disk 0:0 heads = 0
Disk 0:0 sectors = 0
Disk 0:1 enabled = 0
Disk 0:1 = 0
Disk 1:0 enabled = 1
Disk 1:0 = 2
Disk 1:0 media = 1
Disk 1:0 connected = 0
Disk 1:0 image = Default CD/DVD-ROM
Disk 1:1 enabled = 0
Disk 1:1 = 0

Under the warning dialogue, VM says "Boot from hard drive... No boot device avaliable, please Enter to continue".

This machine is machine is triple booting OSX 10.5.2/Ubuntu8.04/WinXP SP2 using rEFIt.

Also, this is what is coming out of diskutil:

$ diskutil list
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *186.3 Gi disk0
1: EFI 200.0 Mi disk0s1
2: Apple_HFS Mostly 154.8 Gi disk0s2
3: Microsoft Basic Data 15.2 Gi disk0s3
4: Microsoft Basic Data 16.1 Gi disk0s4

#3 is the Linux partition, and #4 is the Windows partition.

This is from my boot.ini:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(4)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(4)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

My machine is a Macbook Pro

Can anyone help me out? Thanks
