Windows 10: Two Windows on Two different mode (Bios & UEFI) How to dual boot?

I have a 250GB GPT SSD and installed Windows 10-64bit in UEFI mode.

Also,

I have 1TB MBR HDD and installed Windows 7-32bit in BIOS mode.

Currently, I have to go to bios setting every time and change boot priority manually in order to boot from another windows. Is there any way to use Windows Boot Manager (dual boot) instead of selecting manually from mainboard setting?

UEFI bios, win10 on two different drives, one 1607, one 1703 creators update

Received a request from from the MS community forum team to the status of this post.

Should have kept this simple, 2 separate hard drives both with win10, 1 1607 the other 1703.

Have been using the hard drive that has 1607, instead of upgrading 1607 to 1703, I just wanted

to swap drive 1 (1607) too drive 2 (1703).

Just wiped the drive with 1703 and it in use as a storage drive.

UEFI bios, win10 on two different drives, one 1607, one 1703 Creators Update.

Had issues with 1703 Creators Update on this pc, mainly audio, dts & dd.

Had cloned 1607 first before 1703 Creators Update on this pc, swapped drives.

Now getting messages to install 1703 every day.

The question here is this, I do not want to take the chance of the same issues recurring.

Would it be easier to swap out the drive that has 1703 or cause issues with data

corruption on other media (storage) as it did when swapping 1703 to 1607.

Other then reinstalling W7 in UEFI to a GPT drive, or reinstalling 10 in Legacy mode to a MBR disk, then no.

You`ll have to keep switching, you are going to have to choose a bios method and stick with it if you want a true simple dual boot.

I would consider the way you`re doing it a real hassle and wouldn`t think twice about fixing it correctly.
