Windows XP, Microsoft’s flagship operating system, is widely recognized as the company’s most reliable consumer OS yet. With WinXP, Microsoft eliminated the Windows 9x architecture from its consumer OSes and adopted the technology core of its Windows NT and Windows 2000 corporate OSes. This strategy considerably beefed up reliability and virtually eliminated the constant crashes that plagued products such as Windows 98/Me.
Windows users hailed the dawn of a new era of reliable, crash-free Windows computing. But in spite of the significant improvement to Windows reliability, WinXP is not crash-proof. After all, we are talking about a program packing millions of lines of code that must work in a virtually unlimited variety of computer configurations. And we haven’t even mentioned the wide variety of computer user skills, from raw rookies who can barely turn on their PCs to accomplished experts who love to tinker with everything in their computers.
WinXP is much improved, but it does crash from time to time. And sometimes crashes occur at the worst possible times. Startup and shutdown crashes are probably the most frustrating for Windows users. Startup crashes are especially vexing because you can’t even get your system going long enough to diagnose and solve the problem. Shutdown crashes are frustrating also: Just when you think you can push away from the computer and go on with your life, a mysterious crash throws a monkey wrench into your plans. A 15-minute check-your-email-and-log-off session suddenly turns into a five-hour troubleshooting ordeal.
When crashes occur, WinXP usually presents you with a message attempting to describe the error and, in some cases, telling you what you can do to fix it. The only problem is, for those of us who aren’t programmers or Windows experts, most error messages are virtually incomprehensible. Instead of making things clearer, cryptic error messages only muddy the waters. Seeing “Non-system disk or disk error” at startup sounds pretty serious, right? In the next few pages, we're going to cut through WinXP's gobbledygook and take a closer look at some common WinXP startup and shutdown errors.
STARTUP ERRORS
Error Message: “Non-System disk or
disk error . . . Replace and strike a key
when ready.”
Translation: This simply means that WinXP is attempting to boot from a disk (be it a floppy diskette or one of your hard disks) that doesn’t contain the system files WinXP needs to start. WinXP needs access to certain bits of information when it starts up. Your hard drive’s boot sector, a specific location on the disk, contains the startup files WinXP needs to continue the boot process. If WinXP can’t find those files, the boot process stops cold.
Solution: This one is either a simple mistake or a catastrophe. First, check to see if you have a floppy diskette in your drive. Nine times out of 10, this error is caused when you leave a floppy in the disk drive, turn off the computer, and then turn it on again without taking the diskette out of the drive. If the floppy is not a system disk with the required boot files, WinXP won’t launch. Check the floppy drive, and if there is a diskette in it, remove it and press any key on your keyboard. Windows should now start up normally.
If a forgotten floppy disk is not the cause, then you’ve got a much bigger problem on your hands. Somehow, your hard drive’s boot sector has been damaged or erased. This is typically caused by either a boot-sector virus or a hard drive failure. Most antivirus programs let you create a rescue disk designed specifically for those times when a virus renders your computer unbootable. If you created a rescue diskette, insert it into your floppy drive, restart the computer, and follow the antivirus software’s instructions to clean the boot-sector infection and restore your computer.
If you don’t have a rescue diskette, go to a friend or co-worker who has one and either use his or use his antivirus software to create one, even if you use different antivirus programs. Right now, your main focus should be on disinfecting and booting your computer.
