I setup my mac to dual boot, seems when entering the firmware settings i set a password. Now it boots in Windows and when i tey enter the disk utility during startup, it asks for a password: i don't remember what it is. I am stuck using windows. Anyway to reset the password.

Set a firmware password on your Mac - Apple Support (CA)
And do not forget the below to have any hope of Apple doing anything with this machine
If you forgot your firmware password
If you can't remember your firmware password, schedule an in-person service appointment with an Apple Store or Apple Authorized Service Provider. Bring your Mac to the appointment, and bring your original receipt or invoice as proof of purchase.

Hi Yogi_Austin,
Unfortunately, it sounds like you had set a firmware password. It is particularly difficult to remove, and on some models impossible without Apple's help.
What year was your iMac made in? This determines whether the firmware password can be removed on your own.
EDIT: If you have the Boot Camp tools installed on Windows, run Apple Software Update and install all available updates. Then, you could use the Boot Camp Control Panel to set the startup disk to "Mac".
Thanks for that info. Unfortunately, you will need Apple’s assistance to remove the firmware password (unless you remember it). Please contact Apple Support and set up a hardware appointment. You will need proof of purchase for this.
Alternatively, did the Boot Camp suggestion work to start up in macOS?
It is a 27inch late 2015 imac.
