回复：Changing a PC's Boot Order in the BIOS.

Thanks LAChinese again. Very helpful and inspiring advice.

I followed the instructions from your link, trying to change the Boot Order to USB as No.1, but failed or no response as result.

That is, the default order still holds (1- USB Key, 2-USB FFD, 3-USB HDD, 4-HDD (Hitachi XXXX), 5-USB CDROM, 6-LAN: MBA v11.XXX), 7-N/A, 8-N/A., even after I selected and saved with F10. It seems that my change request didn't get executed, and the malfunctioned Windows from HDD always prevails in order. Sad my S10.

Any more advice? Thanks.
