Registry Editor Problem

Back again Greg.

I'm sorry that I must appear somewhat stupid at this. It is new territory for me, or perhaps I'm just a slow learner. The F12 Start up menu did come up as you said, and then the BIOS, but I don't see my bootable Media that is plugged into a USB port. Am I suppose to see it somewhere so that I can change the boot order? It's not in Devices or in the Startup section. Hope that I'm not waisting too much of your time for something that's very simple for you. Stephan.

As I wrote in my first post explaining how to boot media, use the Lenovo F12 Boot menu key and not the BIOS setup key to enter and change the boot order which is old-school not used any longer with UEFI where Windows Boot manager must be set first to boot at all times.

In your first screenshot they word the Boot menu key as "Temporary Startup device" which is a little awkward and may have misled you. But it is what you want, as the directory shows in my first post, the BIOS Boot menu interrrupt key for Lenovo is always F12.

Then continue with the rest of the steps.

Hi Greg,

I created the Win10 boot Media from another Win10 computer using a clean 64MB Flash drive, and then inserted the Flash drive into a USB slot on my Desktop Lenovo and pressed the Start button. The F1/F2 boot Keys will not directly open my BIOS on my Lenovo. I have to get to the BIOS by pressing the Enter button during Start Up which opens an Options window, then selecting F1. But once I'm in the BIOS, I don't know where to find the boot Media that I've plugged in or how to proceed. Am I missing something in your instructions? Please see attachments below:

Gerdi -

It's obvious you need Step 3 to create bootable media which is the only repair method that doesn't require a password. I give detailed instructions there how to create the bootable media, how to boot it and then the numbered list of repairs to try which now dont' require a password and may work better than the onboard repair mode you already tried.

So please go back and follow the steps I gave, then if you get stuck just ask back and I'll guide you further.

If you have your files backed up you could skip to Option 7 to do the Clean Install which shows you everything that works best in Windows 10 and is such a great learning experience in itself if is worth doing it over. You will get and keep the best possible install to the exact extent you stick with the steps, tools and methods in the linked tutorial.

If you don't have your files backed up it shows how to use the bootable media to do so in Option 8.

Hello again, Greg

I have been going through your suggestion points with the following results:

1. I have already pursued this direction with no luck because it is asking me for my password, which is the problem, especially for the Command Prompt. FYI. I do not have Bit Locker enabled.

Option 1 & 2 require a password.

Option 3 - Do not understand the concept of dual boot. My Window OS on all previous computers are OEM so I'm not sure if these qualify and I don't have a Win10 disc.

Option 4 - No recovery drive.

Option 5 -No USB installation.

Option 6 - Accomplished the procedure six times, but no WinRE.

Option 7 - Cannot access Command Prompt without password.

3. I have downloaded the (Win10_21H2_English_x64.iso) onto a USB Thumb Drive, but not sure how to use it. Sorry, but not sure if I plug it into another Win10 computer and get something from the OS, or does it go into my computer to boot. I can get into my Lenovo Bios by pressing the Enter key during Start Up.

FYI. I just put a new HD in my computer about 2 weeks ago, so my System is very clean at the moment. I did not like the assigned User name so I mistakenly try to tweak and change it in the Registry.

I am very grateful for your help and knowledge.
