SP2 installation

[owenh]

I recently got battlefield 3 to finally play on my pc , but after several tries it wouldnt work and i found the problem was I needed to upgrade from sp1 to sp2, but every time i try to install it just says "update couldn't install" or something like that with an error 0x80004005! ive tried repeating installing 3 times so far but yet no luck! any help would be much appreciated!!!

According to MS :

When you install Vista SP2, the Vista SP2 installer must update the system boot files. If third-party disk management tools are used to "clone" disks or partitions, the SP2 installer will be unable to uniquely identify the correct system boot files.

See here for further details and how to hopefully get past the error !
