HELP! Dual Boot.

Crestfallen · 15 May 2017 at 18:55

Hi,

Can any of you help me?

I have a PC with 4 HDD's. Two of them have Windows 10 installations, one has an old Vista installation (all legit), and the other is just data.

I was having some black-screen issues so replaced mt gfx card.

After installing the card, and booting, the boot menu no longer knows about my main Win 10 installation (which has all my personal stuff on it email and so on). It will only let me boot onto the Win installation which I use for work or vista (which is no longer used).

I can see the other drive/installation in explorer, all the file are there it's fine, but the PC no longer recognizes it as a boot option.

How can I recover the boot option without re-installing win 10 on that drive and wiping all the data?
I have tried the limited options in the system boot options, but since it's not listed in the boot manager it can't load the other OS.

Any ideas?

Have you checked to make sure the BIOS is seeing the correct drive in boot manager- I would also tri (tri- for all you OSW guys out there!!!) just connecting the drive you want to see and check that out

Try installing EasyBCD to the OS that will start,you can then try adding entries to the drives for the different OS's. EasyBCD is made by Neosmart.

Thanks for your advice.

I'm back into my preferred installation. Wierdly, I had to disconnect the drive that is pure data, and fiddle with the HDD boot priority in BIOS.
So I've lost my MP3 library, but I have that backed up, so it's not the end of the world.

EasyBCD sounds worth the investment. I've never had problems with BCD's and Boot Ini's in the past, but Windows 10 seems to have a mind of its own.

Right, I guess I'm off to make sure that EVERYTHING is backed up before deciding if I'm brave enough to try and recover my MP3 drive.

Cheers.

easyBCD is brilliant used it since the ark.. had 6 operating systems running of it in one pc at one time. 4 versions of windows and 2 linux distro`s (really no need for them just to see how it could be done) its a great tool and the forum is really great also.
