Win 7 boot files missing or corrupt

I have an Advent Roma 2001 configured, in PC World style, with a "recovery partition" alongside the system partition and, after resolving a hard disk problem, I found that the machine would not start/boot Windows 7. clearly some necessary files are missing or corrupted, but the normal system recovery tools have not solved the problem(s). I'm familiar with the process for resurrecting XP, but not its counterpart for Windows 7...the files and steps for doing this are rather different. it would seem that pretty much everything else is in place on the hard disk, but certain recovery programs report "0" Windows installations when Win 7 is still in place where it was before the disk problem, e.g. it is available to be selected by the main recovery/startup program...this prog can "see" it, but can't access/boot it.

I'd really appreciate it if someone (or some folks) could map out the steps, files, command line statements, etc. so that I can breathe some life into this anaesthetised device sooner rather than later...I may as well work my way through the whole lot rather than using a trial and error method...that might take a long time. however, I'm also happy to be advised on the approach if and where this unnecessary or inadvisable.

thanks in anticipation,

DH

Try running a Startup Repair as this tutorial explains. You may need to run it three times.
