Windows 10: Windows 10 Media USB Install option wiped all existing usb files

i downloaded the "Windows 10 Media Installation" https://www.microsoft.com/en-in/software-download/windows10files onto a USB option and when I open the USB file folder it appears to have wiped out all my previously stored files as well as changed the capacity of the drive from 128GB to 31.9GB. I've never seen this occur before, I've tried restoring via the CMD function, Viewing All Hidden files option...nothing seems to bring them back.

Windows 10 USB boot

Hi there, am not a windows 10 expert. I have a pc in the bedroom on windows 10, I messed up the bootloader trying to fix the xp on that system.

System wont boot, trying to repair via win 10 usb installer.

Downloaded the media creation tool to install windows 10 installer on usb stick. Not compatible with a host of usb sticks I have. Tried the usb sticks that others use, but I think they use rufus; as the media creation tool by win 10 does not detect the usb stick.

So quick question, the win10 machine i am trying to repair the bootloader is a win7 upgraded to win10.
If i were to use the usb win10 installer to "repair installation" does the version of the iso downloaded via the media creation tool matter?

There is three options:
Windows 10
Windows 10 Home
Windows 10 N

Also is there a step by step instead of using rufus as I want to try an alternative method of creating a usb win 10 installer. Preferably with more compatibility.

System is a asus sabertooth 990 (r2?) with AMD phenom X 6.

Also is there any other software I can load onto the usb that can repair the bootloader easily?
That would be the ideal alternative. Thanks

Step By Step from vista:
From admin cmd prompt

3. clean
4. create partition primary
5. select partition 1 (replace 1 with your usb drive)

Copy Windows Vista's DVD ROM content to the Flash Drive

And that's it, boot off your usb disk

 

Windows 10 Media Creation Tool wipe my USB driver -look for a solution of data recovery on the USB

I lost my data after launching Media Creation Tool for windows 10 installation from a USB drive. However, this application didn't give me any warning and directly wiped out all data saved in the USB. I have tried to use some applications to scan which
files still exist, and many have missed file names, which are also important information to me. I have not perform any recovery for the USB because I am afraid it will ruin the opportunity to get the full recovery. Is there any way to get the data/file names
back? Any suggestion will be appreciated.
