Hi ,

I need to get the boot partition name from the user mode. Is there any
API/Register Key to get the boot partition name.

Thanks.

That gets the operating system directory, but the operating system is
not necessarily on the boot partition.

This is just a guess, but I suspect you can get the boot device from the
Win32_OperatingSystem WMI class property “BootDevice”. If this is
correct, and you then need to find the partition on that disk, you could
probably enumerate the partitions and check the Win32_DiskPartition WMI
class for the “Bootable” property (there can be only 1).

Right. One could get the boot ARC path
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SystemBootDevice and
try to translate this to a Win32 partition name.
