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).
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.
