According to picture Boot Device is HarddiskVolume2 !

Why not HarddiskVolume1 ?

Is this effect Windows boot time ?

How to change to HarddiskVolume1 ?

*My SSD installed Windows and Programs
My Hard disk is for backup

Thank You

Windows 10 installs several partitions, one of which is the one you are using now. The others would appears hidden, because they are not assigned a drive letter.

A third-party application such as EaseUS Partition Manager would make these partitions visible. Computer Management may show you these, but I can't say with 100% certainty that it would.

\Device\HarddiskVolume2 is on my SSD not Hard disk right ?

Mine says Harddiskvolume1 (which happens to be my SSD). Perhaps when you installed Windows you left the HDD connected, therefore ending up with some boot data on the second drive?

"HarddiskVolumeX" is *Volume* number X. Volumes are numbered in some fashion and not all volumes have a drive letter.


IMHO, MS uses odd terms. It calls the volume that contains boot loader as "System", and the volume that contains majority of OS as "Boot".

On UEFI+GPT installations the hidden "EFI System Partition" -- ESP -- contains boot loader and could be harddiskvolume1, leaving the "C:\" as number 2.


No, volume number in itself does not affect the speed of booting.

Frustratingly, MS uses multiple terms even in the same OS.

Sometimes Harddisk0 is Harddisk1, depending on the context, for example.
