### 8. Practice of Solving Problems with DOS

After reading the previous articles, I believe everyone has a deep impression of the basic operations of DOS. But simply mastering the above content is far from enough. To solve computer problems, the most important thing is to transform the learned theoretical knowledge into practical skills that you can use proficiently. Of course, this is not something that can be achieved overnight, and it also depends on the accumulation of experience. Now, let's take a look at a few examples with me to find the key points and main ideas for solving problems.

#### Fault Case:
A certain computer suddenly experienced a power outage during use. After the power was restored, the computer was turned on, but the Windows system could not start normally and frequently froze.

#### Fault Analysis:
From this situation, we can roughly infer that: the power outage caused an illegal shutdown of the computer, which damaged the disk files, thereby causing damage to the Windows system and making it unable to run normally.

#### General Operations:
Starting from the perspective of repairing damaged files, we need to repair the damaged files. If the damage is serious, reinstalling Windows can also be considered.

#### Specific Operations:
1. **Enter DOS**: Since the Windows system is damaged, operations can only be carried out under DOS. When the system is booting and "Starting Windows....." appears, press the "F8" key, and then select "Command Prompt Only" to enter the DOS mode. To speed up the repair, we can run the "SMARTDRV.EXE" program in the Windows directory. This is a cache program that accelerates the disk reading speed.
2. **Run the SCANDISK program**: You can add the "/autofix" parameter if necessary. This way, the program can automatically repair after the first selection.
3. **Run the CHKDSK program**: Check if there are still problems and can use "/F" to repair.
4. **Run Windows**: Check if the system returns to normal. If a registry error is prompted during startup, re-enter DOS, run "SCANREG /RESTORE" in the Windows directory, and then select a good registry file from the list.
5. **Reinstall Windows**: If the file system is severely damaged, Windows needs to be reinstalled.

If you cannot enter Windows normally, the task of reinstalling Windows will have to be done under DOS. For novice users, there is still some difficulty in installing Windows under DOS. Now, I will specifically explain the installation under DOS. The installation here uses a CD-ROM to boot. If a floppy disk is used to boot, the operation is roughly the same.
1. **Enter BIOS setup**: When the computer starts self-testing, press the "DEL" key to enter BIOS setup. In "BIOS FEATURES SETUP", set "CDROM" to the first position in "Boot Sequence"; press the "ESC" key to return to the main screen, press the "F10" key, and enter "Y" to save and exit.
2. **Insert the system boot disk into the CD-ROM drive before booting**.
3. **Select "Boot and use CDROM" in the boot menu after booting**. You can also choose to automatically run the Windows 98 installation program after booting, but that is not what I want, and the installation process will be very long. So before installation, we need to run "SMARTDRV.EXE".
4. **After entering DOS, go to the CD-ROM drive letter, use the "DIR" command to view the directory, and then enter the Windows installation directory (the directory name is mostly self-explanatory, usually "Win98", "Win", "Windows", etc.)**.
5. **Run "SMARTDRV.EXE"**.
6. **Run "SETUP.EXE"**, press Enter, and the disk scan will start. After completion, the installation can be entered, and the operation is the same as installing in Windows.

After reading these two most common problems, do you gain something? As long as you master the basic things, face problems calmly, think and analyze carefully, and constantly summarize experience from other failures, you will soon become a computer expert. In addition, helping others solve problems more can also give you more exercise opportunities, increase your knowledge, and thus accumulate more and better capital.

Well, very detailed, very helpful for beginners!

There are no pictures, and the format is not clearly explained! Also, now everyone is using XP, why isn't there an introduction to XP?

I read a simple DOS book last time but didn't understand it very well.

Thank you for your encouragement, I will redouble my efforts!

Learning...

There's nothing much to learn about XP anymore. DOS is more practical.

But it doesn't work well, so it's not commonly used

Thanks... Very detailed oh

I'm new here, want to learn DOS, everyone please give more advice

Learning

I'm studying, thank you. Such good materials.

Why are there no illustrations???

Good stuff, I'll give you a thumbs up after reading it.
