Windows 7: Windows 7 Has Disappeared From Boot Manager

Windows 7 Has Disappeared From Boot Manager


Can anyone help please? I added another drive to my computer today. I am dual booting Windows 7 with Vista x86 and I was using Acronis disk manager to format the new drive and it asked me to reboot. After this is where the confusion started. My windows 7 got stuck in the windows splash screen. I had to install the installation disk to start it. After this it seemed fine until I rebooted into Vista to make sure that it was okay and it appears that acronis was completing it's disc management within this.

It booted fine into Vista but my boot manager shows 2 versions of vista instead of default Windows 7 and Vista.

Thanks for help in advance.

Kind regards

I can't give you specific instructions, but due to an unrelated problem using DDS, I posted a question on the Acronis Forum, and was advised that DDS 10 is not compatible with W7. The member who said this, said that he had used DDS sucessfully booting from the disk, but it didn't sound as though his use was comprehensive enough to cover all situations.

Since you now have enough drives to do so, I would recommend installing each OS on separate drives, while the other drives are disconnected. If done this way, you would not have a boot manager, and you would select the OS to boot by using the Boot Priority settings in the BIOS, or the F8 BBS Popup Menu during boot.

Thanks for the response. I didn't use Acronis disk manager to boot. I just used it to format the new drive.

Before installing the new drive it was running okay. I had slight teething problems getting the second boot to work after installation and I assume that is probably because I didn't disconnect my other hard drives when I installed Vista.

I have only just reinstalled Windows 7 and Vista so I really don't want to have to redo this again.

It does boot into both systems but boot manager shows Windows 7 as Vista Ultimate. I am sure that if I go into BCDEDIT it could be worked out there but I am not entirely sure how to do it.

I also have the operating systems on seperate hard drives.

I have managed to rectify this by completing an edit in BCDEDIT and changing the OS name.
