检查CMOS里的引导区防改设置
用DOS盘启动, 运行DISKEDIT或NDD之类的软件, 检查MASTER BOOT Record and Partition information(Notice the parameter of the hard disk, cylinder/heads/sectors, if it's the same with CMOS setting). If you can't find readable partition information, it may be damaged by virus or something else. (NDD is a utility help you automatically repair the boot record problem and find the lost partition)
If only the master boot record is corrupt, you can run FDISK /MBR to recreate your boot code without losing the partition information.
Good Luck!
