Windows 10+ubuntu 16.0 does not have a Windows 10 boot menu workaround after installing dual systems on the MBR partition

Background:

Hard disk Partitioning method: MBR

Hard disk capacity 256,windows 100,ubuntu 156, where the primary partition installed Windows,ubuntu installed on the logical partition, the file system for EXT4, the entire Ubuntu mounted in the root directory/under, no swap partition.

After installation, there is no Windows Startup menu. Default in Ubuntu.

Workaround:

1. Open grub.cfg File

sudo gedit/boot/grub/grub.cfg

Write the following on the last side of the open file

'Windows ten' {set root= (hd0,1); NTLDR/Bootmgrboot}      

The set root= here (hd0,1), which indicates the partition of thehard disk, where the C drive is, is almost always the case, but does not rule out special circumstances.

Save the option to see Windows 10 when you exit the restart.

2. Direct use of REPAIR commands

sudo update-grub

When you're done, you'll see the boot menu.
