Ubuntu16 to add boot win10

I use a mobile hard drive after loading ubuntu16, the Win10 MBR (Master boot record) to replace, and then is not to go to Win10, was originally installed Ubuntu has been set in the Ubuntu guide Win10, but do not know why not use, really vexed, Think about it, add it yourself.

First you need to know the UUID of the system disk that you installed WIN10, then boot up, then press E to edit and enter grub.

Grub>ls   #把所有的硬盘给列举出来
(hd0) (HD0,MSDOS4) (HD0,MSDOS3) (Hd0,msdos2) (HD0,MSDOS1) (HD1) (HD1,MSDOS7) (HD1, MSDOS8)
Grub>ls (HD0,MSDOS1) 
partition hd0,msdos1: File system Ntfs-label ' Windows10 ', UUID 1c12fc8012fc5fe6-partition St Art at  1024kib-total size 104340316.5kiB

It is possible to know that the disk in which the WIN10 is mounted is (HD0,MSDOS1) and the UUID is 1c12fc8012fc5fe6.

Then go into Ubuntu, open the/boot/grub/grub.cfg with Vim, and add the end:

Menuentry ' Window10 ' {
insmod NTFS
set root= (HD0,MSDOS1)
Search–no-floppy–fs-uuid–set C9/>chainloader +1
}

In fact, the name of Menuentry ' WINDOW10 ' is irrelevant.
Then save and then enter in Terminal:

Grub-mkconfig-o/boot/grub/grub.cfg

Finally reboot the computer to see the added Win10 boot entry.
