About avoiding the error message "Service pack did not install. Reverting changes" when installing Windows Vista SP2 on a dual boot system including OpenSolaris

OpenSolaris installs Grub in MBR. Grub in MBR, however,
interferes with installing Windows Vista SP2. Normally
installing Windows Vista SP2 demands using Windows
Boot Manager when we choose an operating system.

Firstly, we need to boot OpenSolaris using Windows Boot
Manager. Therefore we confirm Fdisk information for device
/dev/rdsk/c3t0d0p0 after installing FSWpart and FSWfsmisc.
c3t0d0p0 is an example and dependent on each environment.
The command lines are given below.

# prtpart

# prtpart /dev/rdsk/c3t0d0p0 -ldevs

Figure 2  Virtual Device Names

After confirming a virtual device name of Solaris x86, we
create the boot image of the OpenSolaris using the
dataset definition. The command line is given below.

# dd if=/dev/rdsk/c3t0d0p3 of=osol.bin bs=512 count=1

After then we copy osol.bin in the directory on FAT32 and
Windows C drive. For example, C:\osol.bin.

Next we use Windows console which requires administrative
privilege. The command lines are given below.

>bcdedit /copy {ntldr} /d "OpenSolaris"
>bcdedit /set {GUID} device partition=C:
>bcdedit /set {GUID} path \osol.bin
>bcdedit /displayorder {GUID} /addlast

After reboot and the selection of Windows through Grub
menu we can boot OpenSolaris using Windows Boot
Manager.

Secondly, we designate NTFS partition including Windows
Vista as an active partition, using for example GParted
and so on.

After then we recover Windows MBR using Vista Recovery
Console. The command line is given below.

>bootrec /FixMbr

Thirdly, after installing Windows6.0-KB948465-X86.exe, we
have applied Windows Vista SP2 on a dual boot system
including OpenSolaris.

Finally, I will be happy to assist you in installing
Windows Vista SP2.
