How to Remove and Uninstall Windows 7, Windows 8, or Windows 10 from Dual Boot PC
If you have more than one operating system installed on your PC, you will see a Choose an operation system (Windows Boot Manager) screen at startup with the name (description) of each installed OS (boot loader entry) listed on the boot options menu.
This tutorial will show you how to remove and uninstall Windows 7, Windows 8, or Windows 10 from a dual boot computer with another Windows operating system installed.
You must be signed in as an administrator to remove and uninstall Windows from a dual boot computer.
EXAMPLE: Boot options menu at startup for Windows 7 and Windows 10 dual boot
Here's How:
1 Boot into the Windows OS (ex: "Windows 10") you do not want to remove.
2 Delete the boot loader entry (click on link) of the Windows OS (ex: "Windows 7") you do want to remove. (see screenshot below)
3 Restart the computer to verify the boot loader entry (ex: "Windows 7") has been removed.
4 Format the drive (click on link) of the Windows OS (ex: "Windows 7") you do want to remove. (see screenshots below)
If the Windows operating systems are installed on separate partitions on the same disk (hard drive) and the Windows OS (ex: "Windows 7") you want to remove is on the partition just to the right of the partition of the Windows OS (ex: "Windows 10") you do not want to remove, then you could combine them by doing this below:
1) Delete the partition of the Windows OS (ex: "Windows 7") you want to remove so it will be unallocated space on the disk afterwards.
2) Extend the partition of the Windows OS (ex: "Windows 10") you do not want to remove into all of the unallocated space.
5 If the Windows OS you did not remove should unlikely fail to load at startup next time, perform a startup repair for the Windows 7, Windows 8, or Windows 10 OS you are trying to boot.
That's it,
Shawn

Shawn, may I make a suggestion? After deleting the boot entry in MSCONFIG, need to click "OK", and "Apply". Then should take the option to Restart. Then after you're back up in the OS to keep, do the formatting, etc.

Restart before doing anything else is what I normally do, only to make sure the BCD data has been updated correctly and the OS not wanted is not referenced anywhere, just partitions with data.

Sounds like a good precaution. I updated the Delete the boot loader entry tutorial linked in step 2 to restart the computer.

If i remove the Win 10 entry from the boot menu keeping only single os but i left the installation partition untouched(without formatting) , is it possible to add that deleted entry again to MSCONFIG so that the second os can be used again ?
Any easier options to add that entry for a novice ?
Thanks . Take care and stay safe.

For a novice (bet you aren't really that novice
), go get a copy of EasyBCD. Freebie that will allow you to put that right back in. Just ask for help with it if it's not real clear.
There are DISKPART commands to do the same, but if you would like a GUI approach and see what it's going to do, try the app.
