Windows 10 how to move bootloader to another drive?

Question

Windows

Installed a second Windows 10 on a different drive. Now I want to remove the disk with the first system, but the bootloader is on the disk with the first system. How to be?

Answer 1

Disconnect the disk or swap them, boot into the WinRE environment from a bootable USB flash drive / disk, burn the bootloader. Enjoy.

Answer 2

And if you take a system image of disk No. 1 and upload the system image to disk No. 2
Utilities for removing the system image: Norton Ghost, Acronics

Answer 3

Or pull out the old disk and reinstall the system again (this should have been done right away).
Or pull out the old disk, insert the installation one. On the install screen, select System Restore and select Troubleshoot Boot. The disk will install the bootloader itself, provided that the bootloader files are on the new disk (this is a 300 MB partition). If this section does not exist, then everything is bespontu, there will simply be nothing to boot from.
