Windows 7 / XP Dual Boot

I did have a configuration that looked like this

Disk1
Partition1: Windows XP
Partition2: Extended Partition
Partition3: Windows 7 in Extended Partition

I have deleted the Windows XP partition to regain space for Win7.
I have expanded the Extended partition to take up the free space.
I have then converted the Windows 7 partition to a Primary partition.

The system will not boot now.
I am getting the BOOTMGR is missing error.

Can someone let me know if I have done something not supported? I have tried to Fix the MBR through Paragon. I have tried Booting the windows 7 install cd and running Bootrec to fix the MBR.

I can install the Paragon boot manager but when I boot it only gives me the option to Uninstall?

Can anyone please shed some light on possible options here...

 

I might add that I am very new to this as I have mostly done this type of thing on Linux it may be something very simple that I have missed.

 

The XP partition you deleted probably was the system partition containing the win 7 boot critical files.

To fix that:

1. mark the win 7 partition active.

2. boot the 7 dvd and run startup repair - it may take 3 runs.

Hope it helps

 

Ok cool. Thanks for your help. The windows 7 Startup repair may take three runs? Why is that? Do I just run it then reboot 3 times?

 

Yes , after marking 7 partition Active, just run startup repair 3 times.

It doesn't fix everything in one go.

 

Thanks yes that got it working...

Apprecaite your help

 

You're welcome.
