Try using CC cleaner to fix your registry. All drivers and services that are loaded during safe mode are essential and you should not disable them. Only thing you can do is to disable some programs that are loaded during startup in windows.
Try to defragment your disk, it may speed up a bit process.
Also if your HDD has lot of data, rather than just windows it is normal that it will boot longer, esspecially on laptop since your HDD is probably 5400rpm.
