Problem Description:
Installation of Ubuntu14.04 under Win7, due to the boot entry/boot loader installation location error (/DEV/SDA1 (Win 7 loader) will not be able to enter Windows (in the Grub interface can see the win7 boot option, click on the black screen flash a few, Back to the Grub interface), but the Ubuntu system will work.
Problem solving:
It took 2 hours to solve the problem through the experience of many previous people in Baidu. It blew up when I saw the Windows interface appear! The perfect solution is as follows:
1, into the Ubuntu environment;
2, open the terminal (alt+ctl+t), input sudo grub-install/dev/sda;
3, download the latest version of Grub4dos (http://download.gna.org/grub4dos/), unzip the file, the bootlace.com copy to the user Directory/home (open a new terminal, input LS, See bootlace.com can be);
4, enter under Terminal: chmod +x./bootlace.com;
5. Under terminal input: sudo./bootlace.com-floppy-ntfs/dev/sda1;
6, in the Ubuntu system into the system disk Windows folder, locate the Bootmgr file, copy and rename to Grldr;
7, terminal input: sudo update-grub;
