OK, here we go...
I need to move the Windows 7 boot manager. I have tried 'rebuilding' it but it only seems to land me back in the same configuration.
Originally I had XP on an 80Gb hard drive (the drive had drive letter of 'C:' and the name 'Boot Disk'.
I then put in a second drive and installed Win 7 64bit on it. This drive had the letter 'D:' assigned to it.
After testing Win 7 for some time I decided to stop using XP.
I altered the 'bootmgr' to stop offering the dual boot option - now I only have the option to boot to Win 7.
Now that I am booting from Win 7 it looks like the old 'D:' drive is now renamed as 'C:' and vice versa.
In the Disk Manager I can see the following:
Disk 0 'is D:' with the label 'Boot Disk' and is 'Healthy(System, Page File, Active, Primary Partition)'
Disk 2 is'C:' and is 'Healthy(Boot, Primary Partition)'
I want Win 7 on one drive - currently it is split across two - one for booting and the other with the actual O/S on it. Every time I have tried to 'fix' this by rebuilding the bootmgr I end up back in the same position.
