Thanks Andre, here is the boot log from Process Monitor https://dl.dropboxusercontent.com/u/64531882/bootlog.zip EDIT - in the boot log I see many "access denied" errors with custom fonts. I Don't know why but all of those fonts seems to disappear ... I have to reinstall them each time I boot my laptop (but Windows says that they have been already installed ...). EDIT2 - surfing the web I've found that this problem is due to the fact that I'm installing fonts that are encrypted! http://goo.gl/vR0jLe Is this causing delay? EDIT3 - HURRAY! Man, you made my day. Reinstalling decrypted fonts solved my problem. Now boot takes less than one minute. Thank you very much Hope this will save many other human's life
