But,
@Hrishi ,I had to uninstall the Deepin Linux,and am now for CentOS-7.
That was because,the wifi connection in Deepin Linux was getting disconnected intermittently.
AND I HAD TO REBOOT THE DEEPIN OS TO ENABLE WIFI TO WORK.
To everbody out there, since Deepin Linux is based on China, I am very,very sceptical about it.
In fact while I was restoring my Windows 10 in the Laptop,with deleting GRUB and under the UEFI mode,I found 2 directories/Folders,which were installed under UEFI . This type of folders were never found in case with other linux distros.
One was some boot file folder(OTHER THAN THE WINDOWS DEFAULT BOOT FILE) and another peculiar folder with some project mentioned on it.
I DELETED BOTH OF THEM,ALONG WITH THE GRUB.
Now succesfully booting onto windows.
