Windows 7: Windows 7 boot manager on wrong drive

Windows 7 boot manager on wrong drive

Hi I installed Win7 X64 on my system where I first had a Vista installed on a 60GB partition on partition C of the first drive in the boot sequence. (two partitions C + D) And I have two other drives with only data H and P
When I installed Win7 I formatted the C partition and it installed flawless.
Then when I wanted to back an image, I found out that WIN7 placed the bootmanager on the P drive. Removing the P drive an trying to fix it with the repair after booting from the DVD resulted in a message that this operating system was not supported. ?
After much searching I found that I could copy the bootmgr to the C drive.
Now my windows starts again as normal from the C drive. But I can see it is using some loader parts from the previously installed vista.
I would like to gave also this loader from Win7 but I cannot find how to get this done?
Is there anyone that has a clue?

mrbert, welcome to the forums

I am not sure what you mean with the above, what "loader parts" from Vista do you refer to and what do you see?

Also, I am not sure what you want to accomplish, can you elaborate?

This is why all other drives need to be unplugged when installing Win7.

Mark the Win7 partition active, then boot into the Win7 installer repair console to run startup repair three times to correctly configure the boot and rewrite the boot manager.

windows 7 X64

Hi What I see is the same status bar right after bios screens. With the vista loading progress bar. Then some seconds black screen and after that I see the windows 7 loading with the appearance and colors of WIN7

When I installed win7 the screen after bios was same style as win7 with 4 moving color dots forming the windows logo.

I tried rebooting from DVD with 1 drive and repair option.
But then I get the message that the repair is not suited for the installed version of windows.

Since you can boot into Win7 now, run the WIn7 installer from the desktop and do a repair install after unplugging all other drives. The repair install in Win7 is an upgrade over itself.

Everything will be saved but the boot issues resulting from too many other plugged drives will resolve.

You will need to reactivate at Computer>Properties link after you get online.

This failing to give the correct Win7 color-flame startup would mean you need to reinstall from boot choosing Custom>Advanced tools to delete current installation, create new partition and format to get the old Vista completely off.

windows 7 X64

Hi Greg,

When I insert the DVD while windows is started the only option that I get is
Install Now.
There appears no repair option.

When I boot from the DVD I get a repair that tells it is not compatible with this OS.

I hope there is another solution then installing again from scratch.
I hav most of my software configured and running which is quite a lot of work:S

The repair install in Windows 7 is different than XP. You run the installer from the desktop as though you are Installing, choosing Upgrade install. All of your programs, files and settings are kept in place while the OS is reinstalled underneath. You only need to reactivate when it starts back up at Computer>Properties.

This is the repair you need to run to recover a dual boot that has been derailed by the presence of other drives which should have been unplugged during install, or somehow had its boot manager diverted to another drive.

[The only repair tools you get when you boot from the Win7 installer are Startup Repair (run repeatedly as there may be multiple issues if you can't boot into OS), System Restore, Command Line and Recover Using an Image you have stored.]

Since your Windows 7 can boot, and your issue is wanting to recreate a dual boot menu with Vista, you need to run the repair install from the Win7 desktop which will reconfigure the dual boot properly.

Make sure you unplug other drives besides Vista and Win7 so the Win7 installer is not confused again when creating your dual boot. However this may make your Win7 unbootable (since the boot has likely been hijacked to one of your data drives) so you will need to run Startup Repair after booting into the Win7 installer until it starts up to Windows 7.

If you would like us to take a closer look at your current drive configuration to determine this with certainty, then post a Screenshot of your Disk Management drive map using the Snipping Tool on your Start menu>programs.
