Help it's urgent

[ProMeth]

I have installed windows twice in the same partition due to some issues, now I want to boot from my old windows by deleting the newer installed one, so how can I do it?

wait what? is that even possible? how did you install it the second time? did you just select the partition and installed?

Uhh, pretty sure when you installed over it the second time the previous install was lost

I made some search for you, because you need it urgent (good that you write that, otherwise everyone would help you so slow) - https://www.quora.com/What-should-I-do-if-windows-10-is-installed-twice-on-same-pc

I hope is fast enough! Damn, I must have special skills for find that.

It's gone. You're going to have to start fresh. 

 

Open Command Prompt in the installer and use the following commands:

diskpart
list disk 

Find which one is your main disk and select it. In my case, it will be disk 0

select disk 0
clean
create part pri
format fs=ntfs quick
assign
active
exit

Then exit Command prompt and install Windows as normal.

This is for Windows installations on another volume or partition. Not for the same partition.

No it is present there as old windows

Are you sure?

I'm pretty sure that msconfig shows all installations, on different or the same drive.

Windows.old folder is your only hope. Is it there? Did you make backups?
