When the linux Red Hat system starts normally, nothing is displayed when the user name and password are entered, and the root and password boxes cannot be displayed normally.

N ト┮┮♀♀⑧ Linux red hat system starts normally, and nothing is displayed when the user name and password are entered, so the boxes of root and password cannot be displayed normally. On this issue, I think it is the installation CD or image file of face version. 2. Leave at least two partitions on the hard disk for the installation system, and 4G is recommended for the partition for the mount point. 3. Record the following equipment models in your computer: mouse, keyboard, graphics card, network card and monitor. And information such as IP address, subnet mask, default gateway and DNS name server address used in network settings. Second, install Red Flag Linux Desktop Edition 4.0. Set the CD-ROM drive to the first startup disk, insert the first installation CD, and then restart the computer. If your CD-ROM drive supports self-startup, the following picture will appear without accident. If you don't operate, 10 seconds will automatically enter the next screen. The mouse can be used as soon as it is started, which is more convenient than the effect; You can only choose to agree to the software agreement, unless you don't want to install it, click "Next". Choose the installation type, generally choose "typical installation". There is also an option: "Restore System Boot", which is used to restore system boot at a later time. Ignore it here, and then click Next. Configuring partitions is a key step. You may lose useful data on your hard disk. Please be careful. The main reason why some people who use Windows for a long time can't install Linux is because they don't understand this step. If you select "partition manually with fdisk program (experts only)", click "Next" to show the following figure. Zoning in this way is not directly suitable for ordinary people, nor for me! Then click the "Back" button to return to the above figure, select "Manual partition with disk druids", and then click "Next". Select "partition manually with disk druid" and list the detailed information of each partition at a glance, which is suitable for me. My hard disk has four partitions. The first partition is Windows XP, so I want to keep it for dual system use. This table lists all partitions of the hard disk. I'm going to use the D disk and E disk of the original system. That is, /dev/hda5(4.8G) is used as the mount point to install the system, and /dev/hda6(252M) is used as the exchange partition. Here I will create a mount point and put it in the /dev/hda5 partition, which is the original (D drive). To create a mount point, click /dev/hda5 to select it. Then click the "Edit" button to open the dialog box as shown in the following figure. Select "/"in the Mount Point column, that is, use the root directory of the selected partition. Initially, the file system type is vfat (that is, the current file system is FAT32). This format is specific to Windows system, and Linux mount points can only use ext2 or ext3, so you need to change the file system format, select "Format Partition as:" and select "ext3" in the selection bar on the right. If you are not confident about the quality of your hard disk, you should also choose "Do you want to check the bad disk?" Put a tick in the front, and then click OK. You can see in the partition table that the mount point has been created. As can be seen from the figure, the mount point has been located in the /dev/hda5 partition, and the file system format of this partition has also been marked as ext3, indicating that the mount point has been successfully created. You must create a swap partition before the next installation. I choose the swap partition in /dev/hda6 (that is, the original E disk). The steps to create a swap partition are as follows: Click "/dev/hda6" as shown in the partition table to make a selection. Then click the "Edit" button to pop up the dialog box shown below. Since /dev/hda6 is used as the swap partition, the mount point column is not selected, and only "Format partition as swap partition" is selected. When Format Partition as Swap is selected, the mount point column is marked as not applicable. Then click OK. As you can see in the figure, the partition of /dev/hda5 is marked as the exchange file system format, and you can see that the exchange partition has been successfully created. It's time for the next installation. Click the Next button in the lower right corner of the screen. Prompted to format two partitions, click Yes, and the following figure will appear. At that time, these two partitions will not be formatted, and the formatting of these two partitions will really start after the installation wizard ends and before you are ready to start copying files. In this step, configure the boot program and select the installation location of the boot record. Generally speaking, the default boot record (MBR) is placed on the hard disk (/dev/hda). The two items listed in the list position in the figure are the startup options displayed in the startup menu, and the startup volume label is the content displayed at startup; The pictures above are Windows and Red Flag Linux respectively. Change "Windows" to "Windows XP"; Similarly, change "Red Hat Linux" to "Red Hat Linux 9"; The steps are as follows: Click on the line "/dev/hda1dos/Windows Windows" to select it, so that it will be displayed as dark blue. In the right box of the Startup Tab, change "Windows" to "Windows XP". Then click on the line "/dev/hda5 ext3 Red Hat Linux" to select it and make it appear dark blue. Similarly, change Red Hat Linux to Red Hat Linux 4.0. Finally, select the system to be started by default in the startup menu. Click in the white box in front of the system that you enter by default at startup to make it a "V". I choose "Red Hat Linux 4.0" and then click "Next". Set the password of the system administrator, that is, the password of the root user, and enter the password again in the confirmation box for confirmation, thus confirming the correctness of the password. The root account has the highest weight in the system and is generally not used when logging in to the system. After setting the root password, you need to create an ordinary account for logging into the system at ordinary times. Click Add to open the dialog box shown below. In the Add New User dialog box, enter the user name of an ordinary account (such as abc), and then enter the password used by this account. Enter the password again in the confirmation box to confirm. Click the "Confirm" button. At this time, you can see an ordinary account named abc in the picture, and click "Next". This concludes the installation wizard. If you still disagree with the above steps, you can click Return to return to reset, otherwise there is no return option after clicking Next. To start the installation, click Next. The first step before copying files is to format the two selected partitions, and then the screen shown in the figure below appears. It didn't take long to start copying files to the hard disk. Preparations for the installation are under way, and it is really extensive. The picture shown below will appear soon. A slow installation process has begun, and you can rest for about 30 minutes. This step is to create a startup disk, recommended! Put a blank floppy disk with write protection removed into the floppy drive, and then click Next. Creating the startup disk. When finished, it will be displayed as shown in the following figure. Prompt that all installations have been completed. After removing the floppy disk, click the Next button. After the system restarts, the startup selection menu appears for the first time. The first startup option is to start the graphical interface normally, the second is to enter safe mode, the third is to enter command prompt mode, and the fourth is to enter Windows XP. If you choose the second option to enter the safe mode, X settings (graphics card and monitor settings) will appear first, and then system settings, which is suitable for users who can't start the system normally. If you choose the third option to enter the command prompt mode, it is suitable for those experts who don't want to waste system resources. Here, select normal startup first, and enter automatically after 10 seconds. The login window appears, and you can change the user name and log in as user abc. Log in for the first time, log in to the system as the administrator root, enter the password, and press enter. The first login will be a little longer. Please be patient. The installation is complete, and now you have entered the system as root user. After entering the system, it will be a graphical interface. There are some tips for the first time, which can help you better understand some basic functions of Red Flag Desktop Edition 4.0, which is very useful for first-time installers. If you don't want to display the prompt window after startup, just uncheck the box in front of "Display prompt at startup" and close the prompt window. This is the landing desktop of Red Flag Desktop version 4.0. The desktop is very Windows-like, very nice! Science and technology are people-oriented, and the most convenient things will be used by the most people, because there will definitely be more ordinary users than researchers, which is absolutely.

Third, the method of uninstalling the Red Flag Linux desktop version 4.0 system: at the prompt "a: gt; _ ",enter" fdisk/mbr "to rewrite the main boot sector of the hard disk. After restarting, there will be no startup menu of Red Flag Linux Desktop Edition 4.0, and then format the partition where Red Flag Linux Desktop Edition 4.0 is located. In addition, the product group purchase on the virtual machine group is super cheap.
