Dual system Ubuntu7.10 and windowsXP installation is so simple

Dual system wanted to do it a long time ago, but always reluctant to put things in the computer already arranged, it has been looking for an excuse to delay until the first few days in the experiment This unfinished wish of the room has become a task that must be completed. I just decided to start doing it. Oh, I am doing a dual system of ubuntu and winXP. For me, it is to divide the space on a hard disk. In two parts, one is reserved for ubuntu and the other is reserved for winXP, but in fact it is not so simple to operate. Below, I will share my experience with you. Office software failure CPU maintenance First of all, when doing dual system is a sequence, I mean: first do winXP after doing ubuntu or do ubuntu after doing winXP is not the same, the same operation will be due to the order Produce different results, it is definitely a certain, huh, huh! Here I explain the reason I understand: sound card failure 1. Press the big button on the chassis to start the power. 2. After the power is turned on, the host starts scanning and checks the status information of the BIOS (Basic Input/Output System) to understand the hardware status of the entire system: CPU, memory, graphics card, network card, and so on. (1.2 two-step linux and windows no difference) 3. The next step is the most critical step: the host starts to read the Boot Loader on the MBR (Master Boot Record). (Well, I will talk about this, because in this article, I mainly want to talk about the dual system problem, and the crux of the dual system to create difficulties for everyone is the reading problem of this MBR. About the system boot Start the description of the whole process I will give you a detailed explanation in the future, huh, huh!) I successfully installed the dual system of ubuntu after winXP, in fact, this installation, and the normal installation of the single system is not much different, I detail Introduce the whole process of my installation: 1. Hard disk partition I am doing a brand new installation, my hard disk is 160G, I partitioned like this: First partition: 20G Second partition: 60G (This space is reserved for Ubuntu) Third partition: 20G Fourth partition: 60G 2. Install winXP system I will install winXP in the first partition, put the winXP system CD, carry out the normal operation of the previous installation single system, you have completed the dual system The first step. At this point this is a typical XP system, huh! It seems to be nonsense, but after you finish the operation, you will not be able to install the dual system. 3. Install the ubuntu system After completing the XP installation, I inserted the ubuntu system disk into the CD-ROM drive, wait a moment, then the ubuntu installation screen appears in the display, perform the normal ubuntu installation operation, all the way, when you arrive Ubuntu partition to create this step, we will do something different here, here you will see the same as the hard disk partition in the first step above, because the Linux system recognizes the hard disk partition type of windows, so the hard disk All the partitions are displayed here. The first partition should be the ntfs partition we just installed XP. We certainly can't move this. Since I want to leave it to ubuntu60G, I chose a 60G partition and put it. Deleted, turned into free space60G, I will create a root partition, swap swap partition and home main partition on this 60G space. I am explaining here, I did this because I planned to leave space for ubuntu60G at the beginning, so I only partitioned it in the first step. In fact, the size of the partition is controlled by you, as long as you keep it. The size of the partition for XP is not lower than the minimum value of the system disk partition, which will cause XP to be unable to install to the partition. Ok, after setting up the ubuntu partition, it is a flat point. Install! Oh, wait ten minutes, ubuntu is also installed, restart the computer you will see a boot menu, which marks the successful installation of your dual system, huh, simple, think back to what you just did. I haven't done it, just a fool-like installation twice. There is another detail. I don't know if I noticed it. I am now creating a partition for XP. The 60G colleague who wants to reserve it for Ubuntu also created a partition. After the installation of Ubuntu, I deleted the partition and re-created Ubuntu. Partition, some people will ask, is this not the case? Let me talk about my experience, just as the reason why I am "all in one fell swoop", huh, huh! Since I installed 60% free space for Ubuntu when I created the partition, note: it is free space, not built partition, but after I finish XP installation, when I install Ubuntu system, I want to spend the remaining 60G free space. When creating the partition, the system prompts me that the number of partitions has reached the upper limit and cannot create the partition. No way, I will try to create the 60G component. Then, when I install ubuntu, I will delete the created 60G partition and then rebuild ubuntu. The root, swap, and home partitions have proven to be viable. Since I am a beginner, why is this problem? I still don't know. In fact, you have to choose how much space you want to leave for ubuntu. If you want to leave 80G for ubuntu, you can create it by 20G, 80G, 20G, 40G. In short, how to create your preference. Finished, it was successful, but it seems that I didn't have any contact with MBR reading. This is why I installed XP with ubuntu first. Ubuntu seems very polite. When installing Ubuntu, Ubuntu will not be barbaric. Rewriting the entire MBR, causing XP's boot to be overwritten, and then XP can't start, but you're going to try it, oh, this problem will definitely happen. XP can be no ubuntu such a gentleman, it will be a robber-like copy of the entire MBR, lost the ubuntu bootloader, so you can adjust the installation order first ubuntu after XP, you can only enter XP.
