Mark the 100mb System REserved partition Active if you have it, otherwise the Win7 partition. Judge by size. If you don't know how to navigate using Diskpart then use free Partition Wizard CD, post back cam snap of drive map and listings.

Boot the Win7 DVD or System Repair Disk to run Startup Repair - Run 3 Separate Times until Vista or Win7 starts. If you've lost the Dual boot, install EasyBCD to add the missing OS: EasyBCD (free Download at bottom of page - no name or email required) .

If this fails Mark Win7 Partition Active and run the Repairs again. This should start at least Win7, so you can install EasyBCD to add Vista to the boot menu.

Hopefully you correctly installed Win7 originally from booted DVD so it sees itself as C when booted, as it does when correctly installed from boot and not run from another OS.

windows 7 ultimate x64

I eccidentely make my D drive active too....

So i follow karlsnooks steps, and it works! Many thanks! beside in my diskpart step:
on detail disk, i found my C partition size is inverted to D;

C: 500gb and D: 250gb.

And i realize for first time i set myleptop, my system partition(C:\) is less than the other one. So in diskpart i set my D partition in to Active and restart - windows nicely working.

Now when i open disk management my D drive still marked 'Active'. How can i set it to non active guys? thank you..
