Hi Andre, thanks for the Tutorial. A couple of days ago my Zenbook UX32VD (Win 8) started to take 4 - 6 Minutes to boot up for no reason I'm aware of. The full boot summary is here: http://www42.zippyshare.com/v/98947187/file.html . From what I can tell the culprit is the SATA AHCI Controller which takes over 4 Minutes to load (the Driver is up-to-date). I wasn't sure if it's a good idea to disable it for testing so I didn't. <phase name="bootStart" startTime="29" endTime="246530" duration="246501"> <pnpObject name="PCI\VEN_8086+DEV_1E03+SUBSYS_15071043+REV_04\3+11583659+2+FA" type="Device" activity="Start" startTime="2515" endTime="242870" duration="240356" prePendTime="240356" description="Intel® 7 Series Chipset Family SATA AHCI Controller" friendlyName=""/> Any help to understand or even solve the problem would be greatly appreciated.
