Problems caused by multi-Linux system boot

Problems caused by multi-Linux system guidance-general Linux technology-Linux technology and application information. The following is a detailed description. I have seen that after Ubuntu is installed, openSUSE is installed. openSUSE is installed with GRUB. openSUSE and Ubuntu are used for guidance. After Ubuntu is selected, it can guide GRUB of Ubuntu, I didn't know how to implement it at the time. I thought this was the case when I saw this article, so I turned around.

A few days ago, I plan to install another Linux instance on the remaining hard disk space of my laptop. I chose ArchLinux (a release version of Super K. I .S. S, which is very good but not suitable for beginners ).

A problem occurred before installation, that is, after ARCH is installed, the GRUB file is under ARCH. If the GRUB boot entry is written in advance after the kernel is updated in ubuntu, in this case, the GRUB of ArchLinux cannot correctly detect ubuntu updates during startup, which may lead to unbootable or boot the old kernel.

Manual modification of GRUB files is cumbersome. Although the frequency is not high, the solution is as follows:

Add the following two lines to the grub configuration file:

Title ubuntu
Configfile (hd0, 0)/boot/grub/menu. lst

According to your actual situation, GRUB of ARCH will guide GRUB of ubuntu, and then the GRUB of ubuntu will guide the system.
