I want to restore the original system loader in order to be able to start Windows again. But I do not know how to do this. Here is where I am at right now:

I tried to encrypt my system partition (Windows 10) with VeraCrypt. During the pre-test (i.e. before any encryption started), VeraCrypt told me that the system needed to be restarted. This should have been the moment when I should have seen the VeraCrypt boot loader, but instead, I landed in EFI shell. I found out that from there I could get into BIOS by typing EXIT. I further found out that I had to disable secure boot in BIOS in order to start the VeraCrypt rescue disk (a zip-file which I extracted onto an USB stick). I tried various options and managed to get the VeraCrypt boot loader running, or so I think because it does not say VeraCrypt boot loader, but just asks for my password However, it will not accept my password, although I am sure that I typed it correctly because using F5 I could see what I typed. I did not know what to type in as PIM, so I left it empty for default. After that nothing happens, it just says (after quite a long time): "Authorization failed. Wrong password, PIM or hash. Decrypt error(3) Invalid Parameter."

Because of this, I gave up on Veracrypt (at least for now) and want to restore my original system loader. This should be possible because the disk is not encrypted yet. The problem is, I cannot find this option in the rescue disk menu. In the documentation it says:
"Your VeraCrypt Rescue Disk contains a backup of the original content of the first drive track (made before the VeraCrypt Boot Loader was written to it) and allows you to restore it if necessary. The first track typically contains a system loader or boot manager. In the Rescue Disk screen, select Repair Options -Restore original system loader."

Where can I find this option? VeraCrypt rescue disk 1.2.3 gives me only the following options to choose from:

d) Decrypt OS
m) Restore VeraCrypt loader to boot menu
z) Remove VeraCrypt loader from boot menu
c) Restore VeraCrypt loader configuration to system disk
k) Restore OS header keys
r) Restore VeraCrypt loader binaries to system disk
v) Boot VeraCrypt loader from rescue disk
h) Help
e) Exit

So how do I restore the original system loader? Somewhere I read that I had to press F8 to see the rescue menu, but that does not help either. Where can I find this option? If such an option does not exist in VeraCrypt rescue disk 1.2.3, how can I use an older version? Or is it possible to restore the original system loader by other means (i.e. using EFI shell)?

Without help, I think my computer and all data on it is lost. I really, really appreciate any help you can provide. Any ideas?
