Multi-boot facility gone

I USED to have, on boot-up, the option of selecting either Windows 7 or an older system.
Windows 7 was the Primary system, but I had XP French on a second drive, and XP English on a third.
The C Drive with 7 on it suffered a sudden catastrophic failure, and I had to replace it with a new drive (Samsung SSD 850 PRO 512GB), but I obviously had to do a new install of 7, which lost me the multi-boot info stored on the old C drive.
So the question is, can I recover the multi-boot function, or has it gone forever?
Here's hoping.................

Thanks for that.
Had a look and it's just gobbledegook to me.
I would probably do a lot of damage trying to use it !

After much reading on the 'net I purchased "Easy BCD".
Ran it, did the necessary, and:
I now have multi-boot back, BUT
When I choose either of the XP installations, I get the following message:

"Windows failed to start.
To fix the problem
1) Insert windows installation disc and restart
2) Choose Language settings, the next
3) Click repair your computer

Now my question is, if I do this, is it going to try to repair W7 on my main drive, or will it find XP on one of the secondary drives?
I have no wish to destroy my W7.

bump, as they say.

Do you have a Win 7 disc you can try a startup repair from ?

Yeah, already tried that. No change.
