Red Flag Linux partition Raiders 1, a new unopened hard disk, a red flag 4.0 installation CD. We have to divide two partitions on this hard drive, one for HDA1 partitions to install the operating system, the other is HDA5 as an extension partition, used to back up important data, so that the data is not damaged when the operating system is reinstalled next time, The C partitions and D partitions like Windows do not affect each other. Second, the partition method 1, set the computer BIOS to the optical drive to start priority. Put the Red Flag 4.0 Install the CD into the CD-ROM drive and restart your computer. 2. After entering the graphic installation environment, until the partition, we choose "Handmade Size with FDISK", click Next, double-click to select HDA to enter the FDISK partition menu. 3. In the menu, we choose N- to add a partition, and the E-extended partition and P-basic partition will appear. Let's first select P to establish a basic partition, then enter the cylindrical size of the partition, we enter the start cylinder 1. Terminate the cylinder as half of the total cylinder. Go back to the main menu, then we select N, then select E, establish an extension partition, enter the remaining cylinder. After pressing the Enter key, the computer will prompt to establish a logical partition, and we press the Enter key directly. When you return to the main menu, you can see the HDA1 primary partition and HDA2 extension partitions and HDA5 logical partitions after selecting a P-list. HDA1 is the partition we want to install the operating system. It is equivalent to the Windows C partition, and HDA5 is the logical partition we have to store backup data, which is equivalent to the D partition. Back to the main menu, select W to write partition table data to complete the partition. 4, now we choose Q to exit in the FDISK main menu, click Next, the partition selection list will appear. Let's choose HDA1, click Edit, select the mount point for /, the partition format, select all space, click OK; click HDA5, click Edit, Mount Point Optional, Partition Format, choose to use all space , Click OK, click Next to start our installation journey. 5, congratulations, we have two Linux partitions after the installation is over. The second partition HDA5 is mounted when the mount point selected when we partition, we can re-mount it under MyComputer, first create a directory under MyComputer, the directory name, such as the directory name HDA5, enter the terminal Mode, use the mount command to mount: mount / dev / hda5 / mycomputer / hda56, we can store important data in the HDA5 partition, please feel free to use it. Third, the next time if the operating system crashes (of course, the possibility is very stable), or we want to reinstall the operating system, then you must be very careful when installing to the partition, we choose GRUB manual partition, choose HDA1 The method is the same as the first time, HDA5 we don't do the choice, click Next, otherwise the operating system will format the HDA5 partition, and the data we save is Over. Ok, wait until the system is installed, what? Without HDA5 partition? Don't tighten, it is normal because we don't do HDA5 during partitioning. So how do you use the data of the HDA5 partition? Intuition tells us that directly mount it, this is right.
