Disadvantages:
1. Because the motherboard does not have a unified USB boot standard, this causes the U-disk boot compatibility is not perfect. In terms of compatibility, ranging from high to low is dos〉pe〉xpe〉xp.
2.U disk is more critical to hardware requirements
3. Installation inconvenience, basically installation difficult degree arrangement for DOS〉PE〉XPE〉XP
4. Although the function is rich, but and we usually use the operating system still has the gap, the speed is not as good as the local hard drive.
