Please help with my Win7 x64 bootup performance issue caused by ReadyBoot(NOT ReadyBoost) boot plan

[LeungHW]

My computer equipped with a traditional 7200 RPM HDD is suffering from serious bootup performance issue from some day I don't realize. The OS is Windows 7 originated in zh_CN but I installed en_US pack (could not be the reason right..).

I applied no "optimization" on Superfetch function ever, then I someday noticed the bootup alway takes too much time, to be clear enough 100+ sec which differs from 35 sec previously.
I checked Suprefetch events and service but found no problem-- it just works fine all the time.
But when I checked on the directory where the trace*.fx files stores [C:\Windows\Prefetch\ReadyBoot] the supposed-to-be-there 5 files are mysteriously gone. Running ProcMon result suggesting that it's Superfetch itself which generates them, and then erases them in a later point of time. Because deleting always happens before I restart the system the next time, the bootup process has no I/O prefetch and cache at all and this caused the slow bootup issue.
Inspired by the bug fix issued by MS about boot plan failure and slow bootup when there're too many restore point for Windows 7, I checked the registry and Microsoft-Windows-ReadyBoost log Iam sure boot plan failed 232(0xE8) caused this problem but Im unable to dig anyything out form the Intermet so I came for HELP！

Any advice is needed, thx...

If i were you, i would back up your data and rebuild the OS..

if boot times are of concern to you, invest in a good quality SSD. My PC boots in seconds. You can use the SSD to keep your OS and program files on and keep large files on a seperate conventional drive.
