Install Ubuntu on a new computer: install win10 and Ubuntu14.04 dual systems on the same solid state drive in UEFI mode (same for 16.04)

Since the author is also a novice in installation, if you have any questions, you are welcome to correct me.

Entrusted to install dual systems for someone else's newly bought Dell xps 13 computer. The machine itself is pre-installed with win10 system, which is installed in UEFI mode. Next, let's get to the point, how to install ubuntu on the original system?

1. Under the disk management of win10, separate a part of the empty area of ​​the solid-state drive and set it as unallocated.

2. Make a U disk boot disk, some use Lao Maotao, Chinese cabbage and other software to burn, there is also a saying on the Internet that the image is directly decompressed, I use the latter method.

3. Press F2 to enter the computer BIOS, set the boot mode to UEFI, and set the fast boot to enable. Switch to configuration, set SATA

Controller Mode is AHCI (this is very important, not setting it to AHCI will cause the hard disk to not be read).

Switch to Security, set security boot to disable (this is the secure boot of win10, there is a saying on the Internet that you don't need to set this, I suggest setting it first,

After installing the system, change it back. ) xps13 is to press F12 to enter the quick bios setting interface, there are changing,,,, select it

4. Select the boot disk starting with uefi to enter the installation interface. There are two options for usb selection, one is to enter the installation in traditional mode, the other is to install in uefi

to install.

5. For the installation partition method of ubuntu, please refer to https://blog.csdn.net/jesse_mx/article/details/61425361, the tutorial for installing Ubuntu 16.04 in UEFI boot mode .

6. I thought I could use my computer happily after installation. After entering the ubuntu system, I modified some settings. When I was about to go back to Windows, a blue screen appeared. So Baidu has a lot of solutions for win10's blue screen when booting in AHCI mode. Since it is someone else's computer, I dare not modify the registry indiscriminately. I used the method of entering safe mode, and then all the time was spent on how to enter the safe mode of win10.

7. First change the hard disk mode back to the original IDE mode, enter the win10 system, and the system will automatically repair Barabara, in the Troubleshooting -> Advanced Settings -> Restart to enter the safe mode option. Then after entering grub, first change the hard disk mode back to achi mode, restart to enter the windows system, press F4 to enter safe mode, all problems are solved. Both systems are now accessible. http://bbs.zol.com.cn/diybbs/d231_844701.html

There are instructions in this

Insert a sentence, if you change the hard disk mode to ide mode, you will not be able to enter the ubuntu system.
