hello, i'm sorry if this isn't the right section for this,but i'm new on this forum.
anyways..
so i've got a optiplex 755 computer that came with windows 7 pre-installed,my brother accidentally messed with windows and the bootmgr was unbootable,and i didn't have any other DVD Drives except for a windows 10 one,so i formatted the so "corrupted" drive,and then,i installed windows 10,and i decided to re-install windows 7 through windows 10 (because windows 10 doesn't seem right for me tbh),anyway,i've ran the setup.exe from the sources folder,i made a 60+GB Partition for windows 7 (this PC has like about 150GB of storage so i splitted windows 10 and windows 7 into half),after installing windows 7 i installed the windows drivers,yada yada,gone through all that,however,the real issue comes into place now..
since i've installed windows 7 on another partition through windows 10's usage,windows 7 was installed on windows 10's bootmgr.
and like,windows 10 is in the C: drive and windows 7 is on a different letter assigned with E:
anyway,i've tried to format the C: drive where windows 10 was located in,and i only get "windows was unable to format the partition" (through the disk management)
i really need help if possible,i just want to get rid of win10.
thank you.

Keep in mind that the Windows installation [or other OS] cannot manipulate the partition that is booted up, cannot kill itself. If you lived next door I could give you the Dell-branded Win7 Home disc that came with my 755 computer that finally died last spring but Win7 is so old don't know if it would activate. When faced with difficult partitioning duties I keep a copy of the GPARTED LiveCD created from the downloaded .iso file, works outside of Windows and is a bootable 'lite' version of Linux.

If Win10 has activated you could do a clean install and it should again be activated when connected to the Internet.
