Windows 7: Windows Boot manager does not find the boot drive

Windows Boot manager does not find the boot drive

Hi,

Have a new computer with freshly installed W7 on a SSD drive. The computer boots properly unless external HD are connected. If I have external HDs connected (USB 3) it fails to find windows. I've been into the BIOS and there Windows Boot Manager is set as first choice and I have disabled booting from external drives.

Why is WBM unable to find the installation on the SSD? Can I manually change the settings in WBM to select the SSD?

Going nuts on this so any suggestion is appreciated.

Christoffer

Hi,

Not sure I understand the question.

If the external drives are connected, the BIOS looks the same as when they are not. The computer does not boot if they are connected, and I do not know what it does to the WBM (I do not know how to access it at that point). If I plug the drives in after booting with them disconnected, everything looks normal.

Cheers,

Christoffer

Chris I meant that if you remove the externals it will boot? because it sounds like the machine is trying to boot from one of them for some reason.

Now I see that you have done that so I am just puzzled as to why those drives are not being seen in the BIOS. Are they listed in Device Manager? ie Computer > Manage > Disk Management?? I am not trying to be funny just curious as to why that BIOS is like it is.

Try this.

Boot the computer and then hook up the external drive.

Then complete this tutorial by Golden so we can have a look.

It could be a combination of boot order and which partitions have the system flag.

Ok mate sorta understand that so am I right in thinking that one of the other drives has some sort of priority "hit" for booting?

Hi again,

Here is an image of the drives from the computer manager.

I don't think the issue is in the BIOS, but rather in the windows boot manager. Regardless if the drives are connected or not, the BIOS setup looks the same, where I have WBM as first choice and then only the DVD drive. I've switched off booting from any other source. So as far as I can see the computer tries to boot using WBM and then fails if the external drives are connected.

WBM fix?

Hi again,

Anyone with a suggestion for a solution? Or a tip on how to manually fix/check the WBM to make sure it looks for windows in the right place?

Regards,
