1. Description of the situation
Existing system windows (installed on C drive), Ubuntu, System boot for grub boot
2. Install WIN10 using the Winntsetup in WinPE
Take My computer as an example, the system has been installed in the C drive, and the C drive is the active partition, "Boot Disk location" selected as C drive
"Location of installation Disk" selected as e-drive, "version" select Pro
"Mount installation Drive" I chose the e-disk (installation location), do not understand the role, the internet said "as long as the installation of the installation drive option is checked, there will be no problem with the disk character interleaving"

The C drive disappears after installation, and the C drive can be displayed by Disk Management.
3.grub Boot Installation
Due to the installation of Win10,grub is overwritten, you need to reinstall Grub to enter Ubuntu, specific installation methods see my Blog "Ubuntu Grub u disk LiveCD repair method "
PostScript: So far, the road to experience WIN10 began, and now make a variety of attempts.
