PC will not boot or self repair

Thank you. However, after creating an ISO DVD and following your detailed directions, I still cannot boot my pc.

After booting with the ISO, and selecting Startup Repair, the application went through "diagnosing your pc" TO "attempting repairs" then "startup repair couldn't repair your pc."

I think I also found out how this mess started. I have a picture I can forward if requeted that shows system restore showed that there was an apparent windows update that took place, unbeknownst to me, at exactly the same time! It didn't allow me to
access it, or any other listed restore point.

Anyway, I'm still unable to work. Whats my next step?

 

Windows10 update damaged something, attempting repair, some advise adv

They are Operating Systems that aren't based on MS/Windows code.
Ubuntu is a Linux Distro (there a lots of them).

You can run them from a CD/DVD/USB without installing them on your PC.
You can choose to install them if you want (for purposes of recovering your files you won't need to).

It will take a few minutes to boot a Linux Distro from an optical disc (installed versions are at least as fast as Windows though).
Note:
You may need to adjust the boot order in your BIOS/UEFI, if your PC won't boot from an optical disc (or USB) by default.

Once it has booted you should see a desktop similar to Windows (or Mac) depending on the Linux Distro you've used.

I have made some screenshots of my Linux Mint 18.3 (installed & customised) setup as a guide.
Running LM18.3 from a Live CD/DVD/USB will look different.

Step 1
Once the Desktop appears do one of these:

1. Double click on the Computer icon
2. Click the File Manager icon

Step 2
Browse to the folder that has your files
Even though it looks different to Windows it works basically the same
The left pane lists the drives/partitions on your machine
The right pane shows a directory/folder tree
You can double click on a folder to view its contents (the tree structure will start at the folder you clicked)


Step 3
Insert a USB HDD/Stick to save your files to.
The File Manager may open a new window showing the contents of your USB drive.
You may prefer to copy between windows in which case you can ignore Step 4 below.

Step 4
You can open a twin pane view to make transferring the files easier.

1. Go to the View menu and choose "Extra Pane"
2. Click in the new pane (right pane) and then click on your USB drive (in the left pane which is showing the drives/partitions on your machine)
3. Click in the pane (middle) that is showing the files/folders you want to save and select them

Step 5
The selection process is the same as Windows (i.e. you can use the Ctrl and Shift buttons to select multiple files).
Once you have selected the files/folders you want to save, simply drag them, or "Copy& Paste" them, into the USB drive pane/window.

 

Windows 10 PC, Unable to Repair/Restore

I turned on my PC to see a blue Diagnosing, Attempting Repairs set of screens.

When I try to restore to an earlier point via the menu, it tells me it is "unable to do so." That is with and without saving the files. The next step was trying rstrui.exe via Command prompt, but it could not pull up any restore points (I am a restore fiend,
so there should be at least 3 from the last two months, but nothing showed to option).

I tried to have it "Open windows 10," and it finally gave me this message;

Windows could not load properly, etc.

E:\\WINDOWS\System32\LogFiles\Srt\SrtTrail.txt

I though putting in my old Windows 8.1 and it only kept telling me to "start Windows normally."

Followed another suggestion for Command prompt using bootrec.exe fixmbr, but the same results.

Am I going to need another computer to force this PC empty and start from scratch?
