Hi
George Crothers and SIM2,
You solutions have been very helpful, thank you very much !!
After
performing George's method, I reached another difficulty.
After
the final reboot, I got the following message:
NTLDR is missing
Press CTRL+ALT+DEL to restart.
It turns out to be a known issue, WindowsXP updates the Master Boot Record (MBR), which causes the system not to recognize the Win7/Vista OS partition (that was restored).
I can only guess this MBR update was done by the "Mini XP" in Hiren's BootCD.
The solution is to perform a "Startup Repair" from the Windows Install DVD,
which will repair the MBR, and then it's done.
If you don't have the Windows Install DVD, it's advised to create a Windows Repair DVD (or download, if you can find it) before starting the entire process.
See below link for details,it's for Vista/7/8 alike :

Note: Even when receiving the "
NTDLR is missing" message, you _can_ boot the Restored OS by doing the following:
1. Insert Hiren's CD back into your DVD.
2. Restart.
3. In Hiren's menu, use the first option, which is booting from hard-drive. Hiren's will directly boot your OS. It somehow bypasses the MBR issue.
Of course this is not a long-term solution, but in this manner, if you forgot to create the Windows Repair DVD beforehand, you can create it afterwards in the restored OS.
