This article will introduce you to the graphic tutorial on Windows 7 + Ubuntu dual system configuration. I hope this configuration will be useful for your reference. I have never been involved in a verbal war on Windows and Ubuntu. In fact, each system has its own advantages and disadvantages, and almost no system is perfect. For example, in the BlackBerry mobile phone operating system, to ensure security, software cannot be installed on external storage devices (such as SD cards). Therefore, software can only be installed on mobile phones for storage. However, the mobile phone storage capacity is limited, so the number of applications that can be installed on the BlackBerry phone is basically determined by the configuration of the mobile phone. As for the advantages and disadvantages of Windows, I will not talk about it here, and I believe everyone is aware of it.Do they have to be the same?Do they have to be the same? No, there are many methods to combine them, such as buying two computers! Er, of course, there is also an affordable method, that is, to install dual systems. You can try wubi installation. However, the wubi installation method is like running the system in a virtual machine. There are many unstable factors. Some netizens tried this method before and regretted it later. After such installation, the system will crash easily. Although it is recommended that new users try wubi installation. However, based on the above analysis, trying to install a dual system is not difficult, because it is not difficult to install a dual system. Next we will start the installation journey.Preparations:1. Ubuntu 12.04 LTS has been released for some time. In my previous article "official release of Ubuntu 12.04 LTS", the download link for ubuntu 12.04 has been provided. As for choosing 32-bit or 64-bit, depending on your personal preferences. As for choosing Desktop (LiveCD) or Alternate, we recommend that you select Desktop first. The graphical interface is more convenient. 2. Prepare a USB flash drive or a CD; 3. EasyBCD, a software used to boot the system. There are a lot of files online and you can download and install them on your own. 4. Local disks have storage space larger than 20 GB (recommended)Start installation:1. download the system image and burn the iso file to the CD or U disk. If the computer supports starting from USB, select the latter. 2. then, we provide disk space for ubuntu installation. Choose Start> my computer> Manage> storage> disk management (local ). For example, if your local disk (F) has 80 GB, you want to allocate 20 GB space for Ubuntu installation. Then, right-click disk F, select "compressed volume", enter 20480 in "Enter compressed space volume", and then press "Next ". Note: It is best to select the last disk in the local disk for compressing the volume. The reason is a bit complicated and I still don't understand it; 3. then, restart the computer and set the first boot item of the motherboard BIOS to the optical drive or USB device. 4. go to the Ubuntu installation start interface, select the language, then select "Install Ubuntu", select "install third-party plug-in", and next step; 5. enter to check whether the network is connected. If "No network connection" is selected for the moment, it will be okay. Otherwise, downloading and installing system updates during installation will prolong the installation period and click "continue"; 6, the "installation type" dialog box appears, as shown in. Remember to select"Other options", Otherwise Windows may fail to start normally. 7. The disk usage will be displayed in the new window. This is critical! Click the "idle" partition and select "add" below to configure the Ubuntu partition in the new window that appears. The required partitions include "/", "/home", "/boot", and "/swap" (select "swap partition" in the "used" drop-down list "). "/" Allocates 10 Gb, "/boot" allocates MB, and "/swap" allocates 2 GB (If your physical memory is 2 GB ), the remaining free space is allocated to "/home. For example, the screen displayed by the computer after I allocated the space: 8. then, select the device where the "/boot" partition is located in "device that installs the boot loader", for example, "/dev/sda6 ". This step is especially important. Otherwise, Windows may fail to start. 9. The next operation is relatively simple and relatively low. Other configuration items, such as user name and password, 10. then the welcome page appears, 11. next, restart your computer and you will naturally enter the Windows 7 system. Run EasyBCD, "Add New Entry" -- "Linus/BSD" -- select "GRUB (Legacy)" for Type) "-- the Device option starts with Linux and is about 200 MB in size, because the previously set"/boot "partition is 200 MB. Click "Add Entry" on the right to complete the configuration. After the configuration is complete, the screen is shown as follows: 12. restart the computer again. You will see the following screen, indicating that the dual system installation task has been completed successfully!How to upgrade/uninstall Ubuntu:

In Windows, you need to delete the partition where ubuntu is located, and delete the boot from the EasyBCD configuration, which is very convenient. If you need to upgrade the new system, you can repeat the above process, but the iso image file is of the new system.

How to solve the problem of failure to normally read Disk Partitions when Windows 7 + Ubuntu is configured

When you enter the "installation type", there is a problem that the free disk space cannot be read, and the displayed disk is completely different from the partitions seen in Win7. Previously, the "compressed volume" and other operations configured in Win7 are normal operations. The following figure is displayed:

In fact, the cause of this problem is that Win7 uses "Dynamic Disk" rather than "Basic Disk ). Microsoft, my pure soul is no longer able to speak to you. =

If it is a Dynamic Disk, Ubuntu cannot differentiate the Disk status. Therefore, the next step is to convert a dynamic disk to a basic disk.

Although there are many methods, such as reinstalling the system, this method is difficult to implement. You need to back up important files first, reinstall the system, and then reinstall the relevant desktop software and applications.

We recommend that you use the "partition assistant" to perform this arduous operation without loss, ensuring data security.
