Fixed the problem that wubi installed ubuntu lost boot after Windows 7 was reinstalled. Use wubi to install ubuntu, it provides a lot of convenience for our win7 and ubuntu systems, but once windows reinstalls the ubuntu boot item of the system, it will be lost. It is very painful. Below is a simple method I have explored, you can fix Ubuntu boot Item 1: First confirm that your ubuntu is installed with wubi in win7. And ensure that your ubuntu has not lost any files after Windows 7 is reinstalled. 2. Prepare the ubuntu installation image. 3. Select a partition that has not been placed in your original ubuntu system. Use wubi to select the partition to be installed as follows. For my ubuntu system, use wubi to install the new ubuntu to the f Disk: Then select to install, when the installation is complete, we choose to manually restart 4: Open the command prompt CMD as an administrator and enter the command in the command prompt interface: bcdedit then displays the following red lines of information, which are the places where we want to modify the information and continue to enter the command in the command line: the bcdedit/set Identifier includes the braces device partition = the partition where the original ubuntu is located. A successful operation prompt is displayed. Then you can go to the newly installed ubuntu partition to delete the entire ubuntu folder, and then restart the system. the system will directly boot ubuntu upon the first restart (do not worry about the win7 boot issue) when we restarted again, our cute win7 and ubuntu boot items appeared again ^_^.
