Copy and paste the commands from my post one at a time. Press enter after each.

When we have seen what the effect that has, we can proceed.

It is odd you are getting system recovery prompt, normally on Lenovo you need to press F11 to get that menu. Posssibly your F11 key is a little sticky.

Thanks SIW2. Will now tackle the BCD editing as you advise...

On the point about system recovery prompt, I'm not familiar with Lenovo laptops (this T430 is my first - my other laptops were/are Compaq, Dell, Samsung, HP and Acer). All I can do is describe as accurately as possible what happens and what I see when booting up this machine.

It seems as if almost none of the "normal" Function key options are enabled. According to the Lenovo user manual, pressing F8 on startup should bring up the "Advanced Boot Options" menu with Safe Mode options, Repair Your Computer, Last Known Good etc. On this machine, it doesn't...

The F11 key doesn't seem to be sticky. The user manual does indeed say that pressing F11 on startup gets you to what they call the "Rescue and Recovery workspace". Not on this machine.....F11 doesn't have any effect.

The only way of interrupting the boot process is to hit Enter as soon as the Lenovo logo appears. This brings up a screen titled "Boot Menu" which has five options thus:
Esc - resume boot
F1 - BIOS Setup Utility
F10 - diagnose hardware
F12 - choose temporary startup device
<Ctrl-P> - to enter the management engine setup screen

I've tried each of them except the last, and from this menu the Fn keys work as stated (I have used F12 whenever I wanted to boot from an external USB or disk).

The screen which I do see briefly if I don't interrupt the boot process is also simply headed "Boot Menu". It isn't titled System Recovery, or Advanced Boot Options, or anything like that. It just lists the two options (Boot Normally or Restore the original System Image) with a 3 sec timeout.

If I let it boot normally, after that menu there is a momentary glimpse for a nanosecond of a screen which has three lines of green text on it (which might include "NTDLR"????), But it flashes up and vanishes too quickly to read what the wording says. And then the Windows logo screen appears and we're into Win7.

Might be because of reinstall - it should be possible to reinstate both the F11 and F8 functions, if you like. They are both custom bcd entries which use scankey codes ( for the keyboard)

You might be able to get rid of that somewhere in bios - you need to go into bios setup and have a look.


3. The locate entries the bcd you posted can cause problems with multiboot. For example,

The device element is locate=custom:12000002. That tells it to scan to finds the data in element 12000002.

That data is \Windows\system32\winload.exe.

Another way to display the same thing is like this:

locate=\Windows\system32\winload.exe.

The problem is it will stop after those locate functions, useless in a multiboot situation.

We are changing both the device and osdevice values to [boot], which means the active partition (which is C in your case)



4. The other problems are there is no device listed on which to find the \NST\Autoneogrub0.mbr file.

We need to tell it that is on C. We can also use the value [boot] coz C is the active partition.


5. Also your RamdiskSDIdevice was unknown, so again we set it to [boot], which means C in this your case.

Thanks - yet again - for that explanation, SIW2. We're bumping up against the limits of my understanding here.... some of this stuff still seems like witchcraft and magic to me!

But I'm relying on you to interpret the mysteries of the BCD and to reconfigure it to something closer to normality, so we'll see how it goes when I've done the editing using the commands you've suggested. For the moment I'm not too anxious about not having the F8 and F11 keys operating. This seems to be a separate issue, and as long as I can use Enter to interrupt the boot process and then get to F12 so I can when necessary boot from a USB or external drive, that's OK for now.

I've had a look at the BIOS Setup screens, and I confess I can't immediately identify anything which appears to refer to that mysterious "Boot Menu" screen with the Boot Normally/Restore System Image options...

On a separate but possibly related angle, I did come across an article online which said that there were situations in which a Lenovo couldn't be booted into Safe Mode because of a "Security Chip" setting. The article is here. I'm not sure I fully understand the detail, but the process of disabling the chip seems pretty straightforward. I'm tempted to try it, on the basis that if it doesn't change anything then - I hope - I can get back into the BIOS setup to reinstate the previous setting.

If you look in bios under Startup Tab . There is probably something called "Boot Mode" with several settings. Fast/rapid - Normal- Diagnostic.

Select Normal, then save and exit. That might get rid of the annoying boot menu.

Yup, went and had a look at that. On the Startup screen of the BIOS Setup, there are 6 'headings':
Network Boot - [PCI LAN etc]
UEFI/Legacy Boot - set to [Both], with Legacy first priority
Boot Mode - where the only two settings are either [Quick] (the default) or [Diagnostic]
Option Key Display - [Enabled]
Boot Device List F12 Option - [Enabled]
Boot Order Lock - [Disabled]

I re-set the Boot Mode to [Diagnostic] and rebooted. The only difference was on startup two or three additional screens showed up with detailed tech info..... then up came the mysterious/annoying boot menu and on we went into Win7.

So I set Boot Mode back again to the default [Quick] setting, and now the boot is as before: first the ThinkPad logo screen, then the annoying Boot Normally/System Image Restore menu, then a nanosecond of another screen, then the Win7 logo....

So that particular mystery (why do I get that Boot Normally/System Image Restore screen) remains unsolved....

Very curious. Those entries are not in the bcd store you posted.

Take a look at the bcd store on the recovery partition and on the 100mb system partition.

You might need to give the recovery partition a letter to get at it - often Lenovo use Q for that. And give the 100mb thing letter S.

Well the more we dig around, the more curious and strange it all seems to be. I still haven't launched into the BCD editing for which you provided the commands.....

I have a way of looking at what is in all the partitions (but not necessarily editing them) - and that is by booting up into a Live session of Linux Mint from a USB plugged into this pesky Lenovo computer. That's a lot easier than trying to navigate and interpret Windows command prompts....

In such a Live session I can open up the Linux equivalent of Windows Explorer (the File Manager) and I can easily access the Win7 partition (C:), the Recovery partition, and even the System Reserved partition.

Obviously a lot of the files that show in these latter partitions are what I think are called "binary files" (which I cannot open or interpret). There are also some text files (which I can open); and other files which I simply don't recognise.

I can see the BCD (store) file in the 'Boot' folder on the Win7 OS partition (the one which Windows labels 'active'). I guess this is the one which I copied, zipped and posted earlier.

In that same Win7 OS partition (C:) are about a dozen other files. One is a file called Menu.lst which I can open with a text editor..... and that actually contains all the text, and formatting instructions, of that weird/annoying menu screen (Boot Normally/Restore System Image) that comes up when I boot up the laptop normally. And there is a binary file called bootmgr, and others called ANG0, BOOTSECT.BAK, grldr, hiberfile.sys, ... plus a few more.

In the Recovery partition is a Boot folder, and inside that is a bcd file (or store) - evidently another binary file. I think I ought to be able to make a copy of that and post it up if you would like to look at it.

Also in the Recovery folder is a binary file called bootmgr and various other files. One is imagex.exe which I guess might be the actual system image? Interestingly there is also a file called menu.lst which is a text file and contains the same wording as in the Menu.lst file on the Win7 OS partition described above.

Finally I have looked into the System Reserved partition. In there is another binary file called bootmgr, a file called BOOTSECT.BAK, and a folder called Boot inside which is another BCD file (or store?).

That's of course not a complete list of all the contents of these partitions. I have just mentioned those which seem most relevant to the booting process. I'm afraid that although I can see all these files and folders, I don't know what they contain, nor how they work. Would it help to copy, zip and paste any of them? We do seem to be getting into ever deeper and darker waters.....

I am also conscious that this is taking a lot of time and attention, which I appreciate - but I am beginning to feel guilty. I'm wondering whether I should give up, cut my losses, wipe the drive completely, and just install Linux. It's an option - but feels like admitting defeat!

It should be easy to give the 100mb and the recovery partition letters. Just right click each in disk management and assign a letter.

It can be done in seconds. Then you can access the contents from within windows.

If one of those bcd stores contains the entries you see at startup, then that indicates it is being pulled up by your machine at that point.

A child can copy and paste those lines into an admin command prompt, pressing enter after each one. Takes about 20 seconds.
