change boot mode from System Reserve partition to OS partiti

Can you get a Win 10 system that boots from a System Reserve partition to boot from the Win 10 partition and delete the system Reserve partition?
If so, how?

Yes, you can use the chgdtype.tbs script to do that.

Well, yes, but that means changing the disk from GPT to MBR and booting using legacy/compatible mode, right?

It's not completely clear to me whether the original poster understands and wants to to that or not.

The chgdtype script can also remove a SRP partition from a MBR disk, and, thus, configure the System partition to be the boot partition.
For sure, here, there is no need to change the disk type.

Eric,

The script contains this...

// On MBR/EMBR type disk, it can also be used to remove the "System reserved"
// partition and configure the main system partition to be active (unless BIBM
// is installed).
//

Does BIBM need to be uninstalled prior to running the script?

In fact, no. It can remove the SRP (and configure the BCD inside the System) even if BIBM is installed.
But then, you will have to reconfigure the boot partition in BIBM.
Maybe the script should leave a warning in that case?
