What is the make and model of the computer? It's not your daughter's fault that a Restore Point was not created. In Microsoft's infinite wisdom they decided to disable System Restore on Windows 10. I am not sure if it becomes enabled on a Windows 7 upgrade.
You can create a Windows 10 install DVD or USB flash drive using the Media Creation Tool. Boot and click Repair Computer on the below screen. Click Troubleshoot > Advanced Options > Automatic Repair. It may take up to three attempts to do a repair.
Another poster had a similar problem after an automatic update.
Does the computer have a valid Windows 7 key on a COA sticker? You could reinstall Windows 7 and use the key to do a phone activation.
If you need data off the hard drive you can use a live linux disk to copy data from the computer to an external drive. The problem with Windows 10 is it's hybrid shutdown model for quicker starts. This will only allow linux to read the drive but not write to it. You will still be able to copy data though.
I usually recommend Fatdog64 for copying data to an external drive on a Windows computer that does not boot. You can create a bootable USB flash drive using Rufus and the fatdog iso file. Fatdog64-710.iso
Run Rufus with the USB flash drive attached. Select MBR partition scheme for BIOS and UEFI. Leave all boxes as checked. Where FreeDos is shown in the dropdown box select iso image, click the icon, and browse to the Fatdog iso file. Press Start. Any data on the flash drive will need to be backed up as the drive will be formatted.
Fatdog copy instructions;
Boot Fatdog to the desktop. In the lower left of the desktop you will see your partitions listed as sda1...sda2...sda3...etc. On an upgraded computer from 7 or 8 you will see quite a few. Normally your Windows partition will be on sda3 but it may be different in your case. Click once on the partition icon. The partition should mount and a File Manager Window will open. If you do not see your files/folders then close the Window and click on another sdaX icon. Once you find your correct partition attach your external USB flash or hard drive. A USB icon will appear on the desktop. Click once on it and another File Manager Window will open. You can resize and move the two windows until they are side by side by left clicking and dragging the corner and title bar similar to Windows. Once you have both windows side by side highlight the data you want to copy by pressing Ctrl and left clicking or left clicking and dragging a window around your files/folders. You only need to click once to open a folder in Fatdog. Once you have your files/folders highlighted drag them from the sdaX window to the USB flash or hard drive window. A small dialog window will open. Select Copy and check the quiet box. Don't forget your browser bookmarks or email if using a client. Once all your files are copied exit out of Fatdog. You may want to open a few to see if the copy was successful
