Installing RedHatEnterprise5 on Ubuntu on XP

Because the previous Linux version was RedHat, but it was on the server. Recently, the server has been levied, but you cannot leave Linux, so you have installed Ubuntu on the XP system. However, it took a few days, especially for development. There is no way to install a RedHat after uninstalling it. Who makes yourself so real. 1. Installing Ubuntu is a dumb and it will be easier than RedHat. 2. Uninstall Ubuntu and directly use partitionmagic to partition the software.

Because the previous Linux version was RedHat, but it was on the server. Recently, the server has been levied, but you cannot leave Linux, so you have installed Ubuntu on the XP system. However, it took a few days, especially for development. There is no way to install a RedHat after uninstalling it. Who makes yourself so real.

1. Install Ubuntu

The next step is a Dummies. It feels much easier than RedHat.

2. Uninstall Ubuntu

Directly use the partitionmagic partition software to delete ext2 partitions and tile partitions, then restart and dizzy... Cannot enter the XP system. Cause of failure: the grub boot program exists on the deleted partition. When Ubuntu is installed, the boot of the XP system also changes to boot from grub and delete the partition. Naturally, grub does not exist, you cannot enter the XP system. Solution: Use the xp disk, go to "fault recovery platform", log on with the password, enter fixmbr in the console, and press Enter. The system will prompt whether to fix mbr. Enter y and press enter to complete the repair. Enter exit to exit and restart. The problem is solved.

3. Install RedHat Enterprise 5

This is so confusing that it is not difficult to install Linux on bare metal.

However, there are often many problems in the partition area.

It is best to familiarize yourself with the partition structure of Linux. It doesn't matter if you are not familiar with it. Here is a rough description. A disk can contain up to four partitions, at least one of which is the primary partition. Partitions are divided into primary partitions and extended partitions. An extended partition is composed of several logical partitions. The relations between extended partitions and logical partitions are the inclusion relations, that is, an extended partition contains several logical partitions. The size of this extended partition is equal to the sum of the sizes of the logical partitions it contains.

When you create a custom partition, the next step will go to the existing partition page of the system. You can create Linux partitions here. Of course, windows partitions are also displayed here. In this case, calculate the total number of primary partitions and extended partitions displayed. If there are already four partitions, you cannot create them. "You cannot dial the applied partition ..." . In this case, you need to return to windows and use the partition tool to re-partition or merge partitions. If the sum of the Number of Primary partitions and extended partitions is less than four, you can perform Linux partitioning.

But in my experience, it is best to have at least two partitions in Linux, one swap partition and one/partition, which is a last resort. There are many restrictions on installing Linux on windows. If only Linux is installed on a machine, it can be divided into several more zones. In this way, the security and efficiency will be higher. When you want to split Linux into two partitions, it must be a swap partition and A/root directory partition. In this case, windows has two partitions at most. At this time, you can create a primary partition, that is, the partition where the XP system is located, and an extended partition. This extended partition can be divided into multiple logical partitions to meet the requirements of multiple partitions. In short, Linux partitions and windows partitions cannot exceed 4.

If you start to partition so many times, create a swap partition on the idle partition or the partition that you want to install Linux, preferably twice the size of your memory. /Root directory partition, at least 8 GB. If you can add more partitions, split the/boot partition into MB. After the creation, the uplink is basically finished. In the next step of boot program installation, if only one Linux system is displayed, but not its own windows system, manually "add" it ". Most of them will be displayed, but the name will be "other". You just need to "edit" the name. If you don't change it, it's okay, as long as you know it. It will be no longer difficult.

The depressing thing is finally done well. We need to study what these partitions are.
