Description of problem:
after install Windows 2008 R2 Standard Edition 64(disk size: 20G, C:\ 15G,
D:\ 5G) on vhd file (as base image), os can not startup.
I found data error in C:\Windows\System32 :
?--------- ? ?    ?           ?            ? pnpts.dll
?--------- ? ?    ?           ?            ? pnpui.dll
?--------- ? ?    ?           ?            ? PnPUnattend.exe
?--------- ? ?    ?           ?            ? PnPutil.exe

How reproducible:
I tested 10 times, it appear 10 times that os can not startup.

Steps to Reproduce:
1. vhd-util create -n test.vhd -s 20480
2. xm create test.hvm
3. install Windows 2008 R2 Standard Edition 64 ( disk size: 20G, C:\ 15G,
D:\ 5G )
4. can not startup
5. xm des test.vhd
6. tapdisk2 -n vhd:/mnt/img/test.vhd
7. mount -o offset=105906176 -t ntfs /dev/xen/blktap-2/tapdev0 /mnt/vhd
8. ll /mnt/vhd/Windows/System32 | grep ?
?--------- ? ?    ?           ?            ? pnpts.dll
?--------- ? ?    ?           ?            ? pnpui.dll
?--------- ? ?    ?           ?            ? PnPUnattend.exe
?--------- ? ?    ?           ?            ? PnPutil.exe

Additional info:
I install
Windows 2003 Standard Edition SP1 32(disk size: 50G, C:\50G) on vhd file,
the problem disappear.
Redhat 5.4 AS 64(disk size:60G, /: 50G, swap: 10G) on vhd file, the problem
disappear.
Windows 2008 R2 Standard Edition 64(disk size: 100G, C:\ 100G) on vhd file,
the problem disappear.
Windows 2008 R2 Standard Edition 64(disk size: 100G, C:\ 90G, D:\10G)
on vhdfile, the problem
disappear.
Windows 2008 R2 Standard Edition 64(disk size: 20G, C:\ 15G, D:\ 5G)
on rawfile, the problem
disappear.
Windows 2008 R2 Standard Edition 64(disk size: 20G, C:\ 15G, D:\ 5G)
on vhd file,
the problem appear.
Windows 2008 R2 Standard Edition 64(disk size: 100G, C:\ 15G, D:\85G)
on vhdfile, the problem
appear.

ps:
windows 2003 need 3G disk space.
redhat 5.4 need 4G disk space.
windows 2008 need 8G disk space.
the problem disappear means that os can startup and no data error.

compile env and filesystem :
 Redhat AS 5.4

#   Configure guest CPUID responses:
#
#cpuid=[ '1:ecx=xxxxxxxxxxx00xxxxxxxxxxxxxxxxxxx,
#           eax=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' ]
# - Unset the SSE4 features (CPUID.1[ECX][20-19])
# - Default behaviour for all other bits in ECX And EAX registers.
# 
# Each successive character represent a lesser-significant bit:
#  '1' -> force the corresponding bit to 1
#  '0' -> force to 0
#  'x' -> Get a safe value (pass through and mask with the default policy)
#  'k' -> pass through the host bit value
#  's' -> as 'k' but preserve across save/restore and migration
# 
#   Expose to the guest multi-core cpu instead of multiple processors
# Example for intel, expose a 8-core processor :
#cpuid=['1:edx=xxx1xxxxxxxxxxxxxxxxxxxxxxxxxxxx,
#          ebx=xxxxxxxx00010000xxxxxxxxxxxxxxxx',
#     '4,0:eax=001111xxxxxxxxxxxxxxxxxxxxxxxxxx']
#  - CPUID.1[EDX][HT] : Enable HT
#  - CPUID.1[EBX] : Number of vcpus * 2
#  - CPUID.4,0[EAX] : Number of vcpus * 2 - 1
vcpus=2
#
# Example for amd, expose a 5-core processor :
# cpuid = ['1:ebx=xxxxxxxx00001010xxxxxxxxxxxxxxxx,
#             edx=xxx1xxxxxxxxxxxxxxxxxxxxxxxxxxxx',
# '0x80000001:ecx=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx1x',
# '0x80000008:ecx=xxxxxxxxxxxxxxxxxxxxxxxxxx001001']
#   - CPUID.1[EBX] : Threads per Core * Cores per Socket (2 * #vcpus)
#   - CPUID.1[EDX][HT] : Enable HT
#   - CPUID.0x80000001[CmpLegacy] : Use legacy method
#   - CPUID.0x80000008[ECX] : #vcpus * 2 - 1
#vcpus=5
#
#  Downgrade the cpuid to make a better compatibility for migration :
# Look like a generic 686 :
# cpuid = [ '0:eax=0x3,ebx=0x0,ecx=0x0,edx=0x0',
#           '1:eax=0x06b1,
#              ecx=xxxxxxxxxxx0000xx00xxx0000000xx0,
#              edx=xxx00000xxxxxxx0xxxxxxxxx0xxxxxx',
#           '4:eax=0x3,ebx=0x0,ecx=0x0,edx=0x0',
#  '0x80000000:eax=0x3,ebx=0x0,ecx=0x0,edx=0x0']
#  with the highest leaf
#  - CPUID.0[EAX] : Set the highest leaf
#  - CPUID.1[EAX] : 686 
#  - CPUID.1[ECX] : Mask some features
#  - CPUID.1[EDX] : Mask some features
#  - CPUID.4 : Reply like the highest leaf, in our case CPUID.3
#  - CPUID.0x80000000 : No extension we are on a Pentium III, reply like the
#  highest leaf (CPUID.3).
#
#   Configure host CPUID consistency checks, which must be satisfied for this
#   VM to be allowed to run on this host's processor type:
#cpuid_check=[ '1:ecx=xxxxxxxxxxxxxxxxxxxxxxxxxx1xxxxx' ]
# - Host must have VMX feature flag set
#
# The format is similar to the above for 'cpuid':
#  '1' -> the bit must be '1'
#  '0' -> the bit must be '0'
#  'x' -> we don't care (do not check)
#  's' -> the bit must be the same as on the host that started this VM

#-----------------------------------------------------------------------------
#   Configure passthrough PCI{,-X,e} devices:
#
#   pci=[ '[SSSS:]BB:DD.F[,option1[,option2[...]]]', ... ]
#
#   [SSSS]:BB:DD.F  "bus segment:bus:device.function"(1) of the device to
#                   be assigned, bus segment is optional. All fields are
#                   in hexadecimal and no field should be longer than that
#                   as shown in the pattern. Successful assignment may need
#                   certain hardware support and additional configurations
#                   (e.g. VT-d, see docs/misc/vtd.txt for more details).
#
#       (1) bus segment is sometimes also referred to as the PCI "domain",
#           not to be confused with Xen domain.
#
#
#   optionN         per-device options in "key=val" format. Current
#                   available options are:
#                   - msitranslate=0|1
#                      per-device overriden of pci_msitranslate, see below
#                   - power_mgmt=0|1
#                      per-device overriden of pci_power_mgmt, see below
#
#pci=[ '07:00.0', '07:00.1' ]

#   MSI-INTx translation for MSI capable devices:
#
#   If it's set, Xen will enable MSI for the device that supports it even
# if the guest don't use MSI. In the case, an IO-APIC type interrupt will
# be injected to the guest every time a corresponding MSI message is
# received.
#   If the guest enables MSI or MSI-X, the translation is automatically
# turned off.
# 
#pci_msitranslate=1

#   PCI Power Management:
#
#   If it's set, the guest OS will be able to program D0-D3hot states of the
# PCI device for the purpose of low power consumption.
# 
#pci_power_mgmt=0

#-----------------------------------------------------------------------------
#   Configure PVSCSI devices:
#
#vscsi=[ 'PDEV, VDEV' ]
#
#   PDEV   gives physical SCSI device to be attached to specified guest
#          domain by one of the following identifier format.
#          - XX:XX:XX:XX (4-tuples with decimal notation which shows
#                          "host:channel:target:lun")
#          - /dev/sdxx or sdx
#          - /dev/stxx or stx
#          - /dev/sgxx or sgx
#          - result of 'scsi_id -gu -s'.
#            ex. # scsi_id -gu -s /block/sdb
#                  36000b5d0006a0000006a0257004c0000
#
#   VDEV   gives virtual SCSI device by 4-tuples (XX:XX:XX:XX) as 
#          which the specified guest domain recognize.
#

#vscsi = [ '/dev/sdx, 0:0:0:0' ]
