Windows 7: How to make a hard disc a system disc

How to make a hard disc a system disc

I think I may have found an answer to my boot problem. After reading the tutorial on system image restore I saw this statement.

"You can fool it into thinking that simply by marking the 7 partition as active.

May be as well to make it a "secondary" system partition , by copying across the relevant files - in case you forget to hand the active flag back"

How would I be able to make my "C" Windows 7 drive my system drive instead of my "D" Vista drive. Right now my "D" Vista is my system drive.
Or, can I have two system drives at the same time? Remember these are on TWO SEPERATE hard drives.

First make sure you are set to see hidden and protected files in Windows Explorer.

Copy bootmgr file from D: to C:
Copy boot folder from D: to C: and tell it to skip over copying bcd and bcd.log when it prompts.

Run this command from an elevated command prompt. You may copy and paste into it. Hit enter.

bcdedit /export C:\boot\bcd

Reboot into bios and change the primary boot device to be your C: drive.

Boot to Windows and make sure C: is now the system drive. If so, you may delete the boot folder and bootmgr file on D:

If you want two "system drives" so in case one fails you'll be able to boot from the other, don't delete anything and use bios to change drives in this instance.

Thank You Thank You Thank You....you fixed something I have been working on for the last four days. Everything I tried ended up with me doing reinstalls, mbr repairs, changing boot managers, changing the boot order, and everything else you can think of. Nothing worked....this did. Now I can use my RollbackRX program with my dualboot system. Youse folkes are the best.

Please any help?

Also, After moving the exact files that you told me too, and running that scrip in cmd, When i tried to boot off the HDD that has windows installed, i couldnt get to windows... I had to tell the computer / bios to boot from the system drive which has NOTHING on it. :|

EDIT: And yes i know this is a really old thread, but i really need the help, and it is exactly what i need help with.

EDIT:
All good now!!!
My friend told me to put in my Windows 7 disc, boot off that, go into its repair section and launch its CMD. Then type in "bootrec /fixmbr" and that made it so that I could boot from the drive that actually had windows installed!

I have now installed Windows7 on my 250Gb HDD, and am using Software RAID1 to mirror my 2 1Tb HDD's, which is now lets me format because they are not needed to run my 250gb OS.

Huzzah!
