BootManager (BootMGR) is missing?

The "recovery" disk is not a "repair" disk: it is NOT intended to just re-load broken or missing components, but to wipe out the entire hard drive and re-load everything from scratch. Perhaps the directions should have more clear about what a "recovery" is. The fact that you interrupted this process after the first disk means that major parts of the system (and application) software are NOT on your computer. In particular, the BootMGR is the first thing that loads into the computer's memory after the initial hardware checks (called the POST tests). If you have just one operating system on your computer, you will likely never see the Boot MGR, but if you have multiple OS's (even different versions of Windows), it will stop briefly, display a list of known operating systems, and boot the one that you select. Without this component, your computer (as currently configured) cannot boot the OS (which may not be fully installed anyway).

There are other, better ways to repair damaged or malfunctioning drivers, but since you went this far, there is no hope of backing up and doing that task correctly. At this point, your options are (1) find that missing second disk or (2) find a full copy of the Windows disk and install that by hand. In either case, you can boot the computer using the loaders that are on these disks, but you cannot boot from your hard drive (at this point), and you can forget about getting any of your old files from it.

It is possible that I am missing some details here: these kinds of diagnostics are best performed in person, or maybe over the phone. With just one paragraph of description, and with most of my experience on Dell, Sony, and IBM hardware, I may have missed something that Toshiba does differently. Call their customer support line, or borrow a friend's computer to go online and search their support site.

If I am correct and the hard drive has been re-formatted (or at least erased), and you *really* need to recover files from it, there are ways to do it, but since you have partially completed the recovery process, the likelihood of finding undamaged remnants of your files is not great. Go online and search for "data recovery" and go from there. Best of luck.
