If you deleted the System Reserved partition (or it is initially missing) and want to restore it, use the following steps.

Create a new 500 MB NTFS partition:

DISKPART> create partition primary size=500
DISKPART> format fs=ntfs
DISKPART> active
DISKPART> assign letter R
DISKPART> exit

Now you can place the Windows bootloader files on the new partition:

X:\Sources> bcdboot C:\windows /s R:
X:\Sources> bootrec /fixmbr
X:\Sources> bootrec /fixboot
X:\Sources> bootrec /rebuildbcd
