Restoring windows 10 on a dual boot laptop with ubuntu

I have installed dual boot windows 10 & Ubuntu on my laptop.

I accidentally permanently deleted "swapfile.sys" & "pagefile.sys" from my machine while I was logged in from Ubuntu which resulted in loss of my windows 10 account & setting.

Because of hundreds of settings and stuff, I so badly want my windows account back.

The only two solutions that I can deem of are either somehow bringing these .sys files back or restoring windows to an earlier point.

I tried restoring windows but my laptop just stuck after the screen where I choose an option from the two booting options i.e. windows & Ubuntu.

Is there any specific protocol to follow whilst restoring windows on a dual boot machine?
Other than that any other ideas or solutions to get my windows account back would be highly appreciated.
Thanks in Advance

Welcome to the forum can't you undelete it from Linux?

Nope as I shift+deleted the .sys files. And as per data recovery softwares are concerned I can't seem to find any that specifically recover .sys files
If you could please help me out with some software or method to recover those .sys via Linux or windows that would be too awesome.

The error I receive now, that somehow windows was able continue to restore procedure, is unspecified error (0x80070091)

This is the problem I don't have proper backup.................my only bet is windows automatic restore point which is giving me the following error .

As for restoring from Ubuntu is concerned, how to do that as far as I know Ubuntu do not have any such automatic restoring feature unless we explicitly install some third party software. Installing rite now would be of no use as the damage has already been done.

Could you please suggest any other solution?

I only have ONE
