Use a USB flash drive in Windows 10 to install Ubuntu dual system and ubuntu Dual System

Problem description: Install Ubuntu in Windows 10.

Tools used: Windows 10, Ubuntu16.04 LTS installation package, UltraISO, and easyBCD.

Procedure:

1. Before installation, allocate a certain disk space to Ubuntu. I use 170gb to install Ubuntu. My hard disk is large. If the hard disk is small, you can select 50 GB for Ubuntu. For detailed partitioning operations, see disk Allocation Operations under Windows.

2. Create a USB flash drive for the Ubuntu system. The data in the USB flash drive will be formatted here. If there is any important data, back up the data first.

 

Select USB-HDD + in writing mode ".

 

The interface after successful writing is as follows:

  

3. Perform Windows Settings. here you need to reset the Windows Startup settings.

4. Set the system to start from the USB flash drive in BIOS. If you cannot enter the BIOS no matter how fast you press F12 (different keys on different computers enter the BIOS), you should consider enabling quick start for Windows (recommended).

Different computer BIOS interfaces are different. (Press enter to enter the sub-menu .)

  

Select the USB flash drive and save and exit.

 

5. After restarting, go to the Ubuntu installation page. If you have not successfully entered the installation interface, you can choose to go to the BIOS again, and select U disk to start on the first page of the BIOS.

 

To install the dual system, select "other options ". (Unfortunately, I don't know why I have to select "other options". If I have a chance, I will try it again next time .)

  

6. Allocate partitions for Ubuntu. In general configuration, the "/" partition should be allocated 15 ~ 20 GB space, "/swap" is allocated twice the RAM memory, "/boot" is allocated 200 M, "/home" is the primary partition used by the user, you can configure 20 GB or more.

My own settings are "/"-25G, "/swap"-16G, "/boot"-1G, ", home"-128. One thing I want to talk about here is that the "/boot" allocated by my last installation of Ubuntu is 200 M. After using it for a while, the system prompts me "insufficient boot space ", I searched for the boot cleanup tutorial on the Internet. As a result, the kernel data was deleted by mistake, so that Ubuntu could no longer be used. So I installed the Ubuntu System for the second time, this time I intentionally zoomed in "/boot.

Here, "/" is set to "primary partition", and the next three can be set to "logical partition ". The settings here can be restored as long as they are confirmed before "Install now.

Set "/":

  

Set "/swap ":

  

Set "/boot ":

 

Set "/home ":

  

Set "device for installation of boot Guide" to the partition where "/boot" is located:

 

Write the preceding settings to the disk. Before this operation, the previous operations can be restored.

 

7. Perform other settings for Ubuntu. From here on, the installation of Ubuntu needs to be careful.

Set the time zone:

 

Set the keyboard layout:

 

Set User information:

 

Interface for successful installation and installation:

 

8. Set the boot guide for the dual system. Here we use the easyBCD software for configuration. Save the settings and exit.

Add the Ubuntu boot item and select the "/boot" partition in the "Drive" column:

 

9. restart the computer. The Boot screen shows that the dual system is successfully installed.
