I checked the trace. The boot is slow because the ReadyBoot prefetcher is completely untrained. Make a double click and look at the readyBoot IO graph. It is mostly black, which means there are cache misses. This is very bad. The TOSHIBA MK2555GSX 250GB 5400rpm Hard Drive is not the fastest so a fully working Prefetcher is really needed to have a fast Windows boot. I can see that the Windows is Windows 7 RTM. So install the Sp1 + all post Sp1 Updates. Now try it again, please.
