Data recovery from Vista Home with Ubuntu...

Hi!
Can someone, please, give me a full description (command lines included) of how to resolve a nasty situation?
On my HP Compaq Presario laptop I have the pre-installed Vista Home Edition (never ever will buy again a machine with a pre-installed system on it).
Chasing a nasty subroutine (kind of poly-morphical something) I deleted - among others - the boot file. Nothing terrible, because on the back up partition I have the back up :))
The problem is that instead of giving the restore command, I gave the format command and the process started...I stopped it by simply turning the machine off :))
The next turn on just gave me the ''BOOTMGR not found...CTRL+Alt+Del'' message.
And now, after trying several times to at least copy the important files under DOS, I have created a Start Disk with Ubuntu. The disk is running well, but I don't know Linux :))
I have downloaded Foremost, I have opened the archive .tar.gz and my Ubuntu is waiting for me to compile the executable... but I have no success with it.
Somebody...?
Thank you!

Hi. If I understand you

Hi.

If I understand you correctly, you are trying to compile foremost?

There is no need. Foremost is in the Ubuntu archive as well as on the ubuntu-rescue-remix live cd. Just boot the rescue-remix and you can run it.

You can refer to http://help.ubuntu.com/community/DataRecovery for instructions on how to use foremost or Photorec to recover your list files.
