1. Note: It is not necessary to create a blank volume when installing dual systems! ! ! In this way, it will be displayed as FreeSpace when installing! ! !

2. If you cannot open the URL, you can search for "How to separate disk space and merge disk space under win7 Ultimate Edition

2 : Make a USB system disk. The details are as follows:

1. Insert the U disk, open the floppy disk, open - select the system iso file - start - write the hard disk image

3. Save the settings and leave.

Four: (1) Enter the installation interface

Follow the following steps:

1. Enter the "Installation Type" interface, if it displays: " "The computer currently has no deteted operating system", then read the following points 2-4, otherwise directly start from point 5.

2. "The computer currently has no deteted operating system" means that your original win7 system has not been detected (the second picture below) then it means "

64-bit Win7 Another problem will arise, that is, the signature of the GPT partition. If no processing is done, you can log in to the trial version of Ubuntu according to points 1+2. However, when installing through the desktop, you will find that your Win7 cannot be recognized during partitioning. partition. So you need to open the desktop before installation, open the terminal, enter a line of command: sudo dd if=/dev/zero of=/dev/sda bs=1 count=8 seek=512

The purpose is to eliminate GPT Partition Table Signature" - Excerpted from "Linux Commune Network"

3. So how to enter the trial version and enter the terminal to enter the command line? See point 4

4. First, click quit on the "Installation Type" interface. It will automatically bring you into the trial version (don't worry), and then use the shortcut key alt+F2 to exit. run a command, and then you can see the command line window, please enter sudo dd if=/dev/zero of=/dev/sda bs=1 count=8 seek=512

(below As shown in the picture, you can see that I entered it incorrectly the first time. If I try it again, it will show success!)

5. If you used step 4, close the command line window and click on the desktop. "Install Ubuntu...", you will see that it returns to the initial interface, and it displays something like "It has been detected that you have installed the win7 system" (maybe in English). . Otherwise, continue (see the fourth picture below): .... (Supplement the fifth picture, select language, select Chinese, it is at the bottom, keep clicking down)

Four (2 ) Enter the installation interface: As shown in the picture above, the original win7 has been detected!

1. Select the third option, which is "Customize".

2. Did you see that the free space is 41940M, which is probably the free space we designated (a little larger than the 40000M I designated, which is normal)

3. Select Free space,

click the "Free" partition, select "Add" below, the pop-up window is as follows, fill in the partition space size at the top, and fill in the partition to be mounted at the bottom , and then OK. The "/" partition and "/home" partition are all created in this way, and the swap partition should be selected under "for". (Additional: "/" is the primary partition, I filled in 30000M; "/home" Equivalent to "My Documents", the size can be customized; /boot is used for driving, a few hundred megabytes is enough); the swap partition does not need to be too large.

---Refer to "Baidu Library"

4. Install the device that starts the bootloader, pay attention! ! ! Fill in the device of your mount point "/boot" (in the sixth picture, you can see that the device of /boot above and the device of boot boot below are selected the same!!)

5. Click " Install now”

Then enter the registration interface,

1. Fill in your personal information~~~

2. Then start installing the software and system. . . I waited for several hours (maybe the Internet speed is not good, I will scare you to death if I don’t tell you...)

3. The installation is successful, restart! Pull out the U disk!!! (Note: Otherwise, the previously set USB as the first startup item will cause you to reinstall when restarting!)

4. Enter win7 (you must enter win7, and then use EasyBCD Make a boot boot so that system options appear! )

EasyBCD is here!

1. Your original win7 system appears! (The familiar koala appears...)

2. Open EasyBCD

3. (1) Add a new entry - (2) Select "linux/BSD" for the operating system - (3) Drive selection: The partition you used for /boot has the word "linux" in front of it, and the size matches the one you set before (it may be a little different, it will be smaller than what you set!) - (4) Add an entry!

4. Display added successfully! In "View Settings" you can see that there is a Linux system under win7! It worked.

Restart the system and find that there are two options! Log in - enjoy the music ~ Likes and favorites are welcome, thank you xian2r ~
