Solution to the problem that Ubuntu startup items disappear after Windows 7 is installed
The system was originally Ubuntu14. After win7 was installed two days ago, it started directly with win7, that is, the Ubuntu startup Item disappears.
In windows, I tried many methods and ended up failing. Finally, I chose the boot-repair software under Ubuntu to fix the boot item.
First, write the Ubuntu system to the USB flash drive. The process is relatively simple. You can also use Baidu.
Then, the USB flash drive starts Ubuntu.
Select trial after startup. After entering the desktop, open the terminal, press Ctrl + Alt + T, or search for terminal in the search bar.
Add boot-repair software source: sudo add-apt-repository ppa: yannubuntu/boot-repair
Update Software Source: sudo apt-get update
Install boot-repair: sudo apt-get install-y boot-repair
Start: boot-repair
For example:
Click the arrow to fix the problem.
