How to reinstall the system, how to reinstall the computer system (1)

First, press and hold the DELETE button to enter the BIOS when starting the computer, select the Advanced BIOS Features option, press the Enter key to enter the setup program. Select the First Boot Device option and press the Page Up or Page Down keys on your keyboard to set the item to CD-ROM so that you can change the system to CD boot. Second, return to the main menu and save the BIOS settings. (Save by pressing F10 and then pressing Y.) Third, then insert the CD into the CD-ROM drive and restart the computer. The system will boot from the CD and display the installation wizard interface. You can follow the prompts step by step. It is OK to make the installation settings. In addition, if your c drive is not formatted, you will have 2 systems after reinstalling, so it is recommended to drop it. Frequent computer errors are generally not problems with the computer itself. I have always encountered such problems before. If your CD is XP, you should take the following operations. Press and hold the DELETE button to enter the BIOS when you start the computer. Select the Advanced BIOS Features option and press Enter to enter the setup program. Select the First Boot Device option, then press the plus (+) or minus (-) key on the keyboard to set the item to CD-ROM, then press F10 to display the option Press Y and press Enter. This will change the system to The CD is booted. 1. Simply put, formatting is to divide a blank disk into small areas and number them for computer storage and data reading. Without this work, the computer does not know where to write and where to read it. The hard disk must be partitioned before it can be used. After the disk is partitioned, the next step is to format the hard disk (FORMAT), and the hard disk must be formatted before use. Formatting is the creation of tracks and sectors in the disk. Once the tracks and sectors are established, the computer can use the disk to store the data. In Windows and DOS operating systems, there are programs that format Format, but once the hard disk is formatted, the data on the hard disk will be completely gone! So before doing this, first determine if there is still a need for the data on the disk. If it is, then back it up separately. Advanced formatting is to clear the data on the hard disk, generate boot area information, initialize the FAT table, label logical bad sectors, and so on. The low-level format is to divide the blank disk into the cylinder and the track, and then divide the track into several sectors, and each sector is divided into the identification part ID, the interval area GAP and the data area DATA. It can be seen that low-level formatting is a work before advanced formatting, and it can only be done in a DOS environment. And low-level formatting can only target one hard disk and cannot support a single partition. Each hard drive has been low-level formatted by the hard drive manufacturer at the factory, so there is usually no need for low-level formatting. 2. Reinstall the system Before reinstalling the system, it is best to list the backup list. Before preparing to reinstall the system due to system crash or failure, the first thing you should think of is to back up your data. At this time, be sure to calm down, carefully list the data that needs to be backed up on the hard disk, write them one by one on a piece of paper, and then back them up one by one. If your hard disk does not boot, you should consider copying your own data after booting the system with another boot disk, or attaching the hard disk to another computer for backup. In order to avoid the disaster of hard disk data recovery, it is best to develop the habit of backing up important data every day. User documents are treasures, and the first thing to do is to back up. In the data that needs to be backed up, the user documentation is the first to consider the backup data. If you are an editor or author, you need to back up your own manuscript first; if you are a teacher, you need to back up your own handouts first; if you are a composer, you need to back up your own tracks first... Usually, the user's document data is placed In the "My Documents" folder. If the user additionally specifies a folder to store, the corresponding folder needs to be backed up. Internet veterans become embarrassed, just because they forget to collect favorites. Users who frequently browse the Internet generally have a personal address list. The next time you need to search for similar content, you can easily reach your destination by opening "Favorites." When reinstalling the system, if you forget to back up your favorites, the new system installed will have almost one empty collection for you

folder, the good address that was previously reserved will be missing, you will Feeling blinking. Although you may say that I have a good search engine such as Google, but the work that can be put in place in one step has become more complicated, why bother? Therefore, you must back up the "Favorites" before reinstalling the system. Windows XP Favorites is a folder under the system partition, and the username in the middle varies from person to person. To ensure high speed entry, backup input method lexicon Now, entering Chinese characters is nothing more than the two types of input methods: pen type and pinyin. At present, the mainstream pen type and pinyin input method all have intelligent components, that is, the personalized vocabulary formed by the user can be memorized automatically or semi-automatically. Individual users enter Chinese characters in a lexicon environment with their own characteristics, and work efficiency will be greatly improved. If you forget to back up the input method user vocabulary when reinstalling the system, after the system is reinstalled, the input of the personalized vocabulary in the work is equivalent to starting from zero. So don't forget to back up the input method user vocabulary. The user vocabulary is generally in the system or folder, and some input methods themselves have their own lexicon backup interface, which is very convenient to use. E-mail, QQ backup is good, all directions can not be broken Email and QQ and other chat tools are the main contact tools of our modern people. When reinstalling the system, be sure not to forget to back up your email address book and QQ friends information. Both the email address and the information of the QQ chat friend can be backed up by the export function of the corresponding software. In order to avoid the backup of these data after the system crash, it is best to develop the habit of regularly backing up these data in the usual time to minimize the loss in the system after the system crashes. In fact, FoxMail and QQ are quasi-green software, you only need to compress the folders of these two software and save them for use. The driver backup is good, the next time you install the machine, you don't have to look for it. The first feeling after installing the machine is that the screen is flashing to make your eyes uncomfortable, and the speaker has no sound at all. This is because there is no graphics card and sound card driver installed. If you have other boards or peripherals in your system, you will have to reinstall their drivers. Some of these users' drivers are copied to the hard drive folder and there is no installation disk. At this time, you need to pay special attention to the backup of your own driver before installing the system. Don't delete the original directory, please prepare the installation disk first. If the original system file can also be accessed with a boot disk, etc., after deciding to reinstall the operating system and end the backup work, don't rush to delete or format your original. Some systems, you should calm down and think carefully about the files in the original system partition that you do not need to keep. After thinking about it again and again, the next thing should be to prepare your installation CD. It should be noted that you need to set the CD-ROM drive as the first boot disk in the system BIOS. Software instructions or envelopes, with serial numbers installed There is a key to installing the serial number. If you accidentally drop your installation serial number and use a new installation, the installation process will not proceed. The serial number of the regular installation CD should be in the software manual or somewhere on the CD cover. However, if you are using a beta system provided on some software collection CDs, these serial numbers may be in a description text in the installation directory, such as SN.TXT. Therefore, the serial number must first be read and recorded for later use. System error is missing files, overwrite installation try again If the system prompts you to reduce some files when the system starts, or some files have problems, then you should not rush to format your own hard disk, but should first try to cover the installation. The main point of overwriting the installation is to first enter safe mode or boot to DOS, then execute SETUP.EXE on the installation CD or other files used to launch the installer. Note that during installation you choose to install the system files in the same directory as the original system. After such an installation, most of the general problems can be fixed, and more importantly, some of the previously installed applications can continue to be used. Overlay installation does not work, delete the installation of a new set If the installation method mentioned above does not solve your problem, then you can confirm that the backup work is completed, and all kinds of drivers are ready, first Start the system with the boot disk, then format your system partition with the FORMAT command, then execute SETUP.EXE on the installation disk or the executable file for installation, and install it completely. If there is no

drive disk, another directory is new. If you do not solve your problem by following the above installation method, you are not sure if you still have something to back up, or you don't want to Format your own partition, then you can use the installation method of another directory. To do this, execute the installation file after booting with the boot disk and install the system in a different directory than the previous system. In this way, the original driver is still in the old system directory. If your driver is missing, when the system discovers new hardware, you can find the hardware driver in the original directory by prompted. Once all the hardware drivers have been installed, you can safely delete the original system directory. Want to experience new shocks, upgrade installation needs to be replaced If you are using a lower version of the operating system, and you want to experience the same software company just launched a new generation of operating systems, then you can use the upgrade installation method to achieve your ideas. The method is to run the installation file of the advanced operating system directly in the low-level operating system environment. The operating system is generally backward compatible. Windows 98 can be upgraded to Windows 2000 or Windows XP, and Windows 2000 can be upgraded to Windows XP. Most of the original programs can continue to be used after the upgrade. If you are not willing to lose the original low-level operating system and want to experience the charm of the new generation of operating systems, then you can install dual systems. The method is: under a low-level operating system (such as Windows 98), execute the installation files on the advanced operating system installation disk, such as SETUP.EXE, and then choose to install in a new directory during the installation process instead of selecting an upgrade installation. This way, when the installation is complete and the system is rebooted, the dual system menu appears. The same is true for multi-system installation methods, but it is best to follow the low-level, post-advanced installation order, otherwise there will be a lot of trouble. Hard disk backup installation disk, reinstalling the system is more convenient In order to eliminate the trouble of finding the installation disk everywhere, we can backup the system installation disk to our own computer. To do this, create a folder in the data backup area of ​​your hard drive. Copy all the files from the system installation CD to this folder. You need to run SETUP.EXE or other installation files when you need to reinstall. If the system does not crash, part of the recovery is fast. If the Windows 98 system does not completely crash, but some system errors can not be repaired by disk scan or error correction software, then you can use the partial recovery installer of Windows 98. This installer can be found in the folder on the Windows 98 CD. The method is: go to the DOS state, enter the directory, run PCRESTOR, the installer will start. This installation is about the same speed as a hard disk installation, and it does not cause data loss. At the same time, when you reset the hardware, it is usually done automatically. Double-start menu failure is difficult, just XP installation disk If Windows 98 is installed after installing Windows XP, the system dual boot menu is lost. At this time, the following solutions can be used. First adjust the boot order to the CD-ROM boot priority in the BIOS, then put the Windows XP installation disk into the CD-ROM drive. After the auto-loading of the installer, the system will ask you whether to re-install or repair, do not care about it, and exit directly. Finally, in CMOS, the boot sequence is changed to the hard disk boot priority, so that the boot menu will appear after booting again. Do not use the XP system disk, still repair the double-opening. If Windows 98 is installed on the C drive, Windows XP is installed on the D drive, and the E drive is the user data area. We can back up the BOOT.INI, NTLDR, NTDETECT.COM, BOOTSECT.DOS, IO.SYS, MSDOS.SYS, BOOTFONT.BIN and other seven files in the root directory of the boot partition to our E partition. When we reinstall the system improperly and make the dual boot system menu confusing, you can copy the seven files to the boot partition and cover it to solve the problem. Clone backup methods, system tools together 也许 Maybe you will feel that the most troublesome thing to reinstall the system every time is not to reinstall the system itself, but to find and install various applications and

utility gadgets. At this time, a very classic software Norton Ghost can solve your problem. After you have installed the system and some tools, just use the Ghost software backup partition function to package the installed system and tools into a file. When you need to recover, start DOS with the boot disk, then use Ghost to quickly restore this file package to the original partition. Internet cafes use more than one computer to use this method. Computer veterans also use this method. Whether the software needs to be reinstalled, try to set the system in the other directory. Without deleting the application under the original folder, which programs can be used directly without reinstalling? In fact, this problem only needs to be tested. After reinstalling the system, run the executable file in the original program directory. If there is no error message, you don't need to reinstall it. You can treat it as a green software and do not need to reload it next time. Unable to run or prompt for missing files must be reinstalled, these can not be listed as green software. Whether the system needs to be reinstalled, the three rules will help you. If the system has one of the following three situations, it should be time for you to consider reinstalling the system: 1) The system operation efficiency becomes low, the junk files are flooded with hard disks and scattered and distributed. Convenient for centralized cleaning and automatic cleaning; 2) Frequent errors in the system, and the fault is not easy to accurately locate and easily solve; 3) The system cannot be started.
