What does thie error message REALLY mean:

Preparing system post-work for prefetching failed.
PrepareSystem failed.
Couldn't find kernel logger in active logger list.
Couldn't find user-mode logger in active logger list.

?

And this is my xbootmgr.log file:

First thank for analysing.

Sir I don't blelieve that HDD sata 1 IS THE PROBLEM BECAUSE I have another pc with an hdd ata and I have made it to boot for 13s. THis pc has 2gbram but laptopo 4gb.The problem is showe when I installed iolo.

This hdd has inteliwrite. If i uninstall its driver and make defrag and then reinstall driver can solve the problem. Perhaps iolo inteliwrite and dell intelli write are crashed.

Also has any problem with drivers or any other proicess?

Hello MagicAndre1981.

 

I reduced my boot time from ~190 sec to 130-140 sec. It's a big difference, but still boot time is so long. I would be grateful if you could take a look at my .xml log and tell me what can cause that. I know there could be some rubbish which slow my computer, but maybe you will help me to localize it. :)

Thanks in advance.
