Windows 7: Dual boot with Win7 - problem with boot menus on Lenovo laptop

I used Easy BCD and dual boot through Windows Boot manager Linux choice pointed to Grub on Linux partition. Good explanation here as to why you want to preserve the Win Boot mgr.

Yes Snick, that's absolutely right. I know the Matthew Moore tutorials on YouTube very well, and I've been a supporter of his method, and a user of EasyBCD, for years. I have three other computers (plus my wife's netbook) all set up to dual boot Windows with one or more Linux distros. They all work flawlessly.

BUT...... the issue with this refurbished Lenovo T430 laptop (as I tried to explain in my OP) is that the boot arrangements are not "normal". The boot manager, the boot loader, and/or the BCD, appear to have been modified. I don't know whether this was by Lenovo (as part of their OEM Recovery setup) or - less likely - when the laptop was refurbished.

The result is that the normal EasyBCD configuration doesn't seem to work. Although I installed Linux Mint and its Grub into a separate partition, and added that to the BCD using EasyBCD, the boot process doesn't seem to "see" or use that BCD. It only boots, as before, into a briefly-displayed screen with "Boot normally into Win7" or "Restore System Image" options, and then goes on to boot into Win7. So the normal EasyBCD dual boot process doesn't seem to kick in even though Linux shows up as having been added to the list of installed OSs.

I don't know why this Lenovo boots up like that - apparently bypassing the normal BCD and/or boot manager - and I don't know how to change or correct that so that EasyBCD will do its stuff.

Regrettably my requests to the EasyBCD support forum have brought no answers. I was hoping that someone who understands the boot process better than me (and perhaps is more familiar with Lenovo's setup and recovery arrangements) might be able to diagnose and explain. I am reluctant to try to mess around with or "repair" the bootloader - which at least still boots Win7 - until the cause(s) of the problem are pinpointed so that I know what any repair process is aiming to do.

You could post a screenshot of disk managament window, so we can see the partition layout.

You could also post a zipped copy of your current bcd store.

Happy to do both, SIW2, but with slight delay as I'm now away travelling for a few days and have left the problematic computer in a drawer at home while relying on another laptop which is configured normally.


I posted details in my post #3 of the entries in the BCD which EasyBCD displayed; and I listed the (few) differences from what the BCDEDIT command prompt displayed in the terminal. I don't know whether "the BCD store" would reveal anything different....?



What remains a mystery to me is whether, or how, the laptop is currently using this BCD during boot-up, if at all. The only menu screen I see during the process is this mysterious "Boot Windows Normally or Restore System Image" display for a couple of seconds before the Win7 logo/splash screen appears.


Screenshots to follow when I get home later in the week....
