How to properly uninstall Parrot OS - Windows 10 dual boot

Hello,
i installed Parrot OS alongside Windows 10 to separate disk. Please how do i properly uninstall it? I had case, when Ubuntu put bootloader on system disk and than, my bootloader was broken. Should i just delete all partitions created by Parrot OS? I don’t know where Parrot OS puts its bootloader. Please tell me what to do.
Thanks!

well first open the windows
then delete the parrot partition
then rebuild the mbr if your hard disk partition type is mbr
or rebuild the gpt if your hard disk partition type is gpt
after that you can reboot
