Dual boot 2 Win 7s make the second fail.

The situation is simple, just got a new HDD and installed a fresh copy of Win 7 on it - now when i try to remove the previous HDD (with the previous version of 7 on it) it won't boot. Is there any way windows can configure the MBR or am i forced to reinstall ?

It seems you have removed the drive that had the Windows boot files, so the system can no longer boot.

With the old drive disconnected, boot from the Windows 7 DVD and run startup repair several times.

Or fix it manually using the command-line. Some examples:

Shift + F10

bcdboot c:\windows

bootsect /nt60 SYS /force

You can't dual boot when one of the drives is disconnected. If you are planning on disconnecting drives then you need to make sure that both disks have the necessary boot information. Also you probably need to go into your BIOS and change the order in which the computer tries to access it.
