I have an old NEC laptop (PIII 500/128M RAM 10G HD), and there is only an external CD-ROM (connected via a PCMI card). Since the computer is infected with a virus, I want to format the entire hard drive and reinstall the system. But after setting it to boot from the CD-ROM, it turned out to be useless. Later, I found that the so-called CD-ROM couldn't be used without booting into Windows. Looking at the BIOS, it didn't seem to support USB device boot. I wanted to take out the hard drive and install it, but the hard drive of that laptop is extremely difficult to remove. The computer is now running Windows ME system, but it's full of viruses, and it's slow, of course, and completely unusable.各位高手，请问有何办法让我能把它格了再重装系统？如蒙赐教，不胜感激．
