Many new children's shoes do not know how to uninstall Linux, often corrupt grub, resulting in the normal access to Windows.
Here's an easy way to do it, and I've been using this method since I uninstalled Linux, safe, convenient, and fast.
1. First, you must not delete Linux under win. Open the terminal under Linux and enter:
sudo dd if=/usr/lib/syslinux/mbr.bin OF=/DEV/SDA
