How to transfer path '\Device\BootDevice' to drive format

he_dkhe_dk Member Posts: 36

When I retrieve system root path from '\SystemRoot' by using function ZwQuerySymbolicLinkObject,
I got '\Device\BootDevice\Windows\' in Windows 10.
Can anyone tell me how to change '\Device\BootDevice\Windows' to drive letter, such as 'C:\Windows'
Thanks~
