hey Wes,
Thanks for the aid.
I've reviewed the links but I feel they're too much firepower for such a trivial issue.
I'm almost certain that all I have to do is access the contents of the laptop drive so that I can delete ntoskrnl.exe (the modified, problematic, incompatible version) and replace it with the backup I made just before trying to change my bootscreen. The backup is named ntoskrnl.exe.bak and is located in the same directory. Unfortunately, the system doesn't boot so that I can't reach Safe Mode. Also, using the CD gets me nowhere as well because it doesn't recognize a windows installation on the disk. Additionally, Recovery Console doesn't recognize the existence of the drive so I can't get in that way either. Lastly, I attached the drive to my desktop system as a slave using a Notebook-to-IDE Adapter Card. The desktop bios and Device Manager recognize the drive but oddly, Disk Management recognizes the whole drive as Unallocated Space and provides as the only option a conversion to a Dynamic Disk. Windows Explorer doesn't show drive letters corresponding to the drive (which includes 1 additional partition) but it does skip a couple of letters under My Computer indicating that the system recognizez the drive and has assigned it letters but is not making them available.
Helppppppppppppppppppppppppppp!
Thanks again.

PS: I've tweaked XP on the laptop drive with instructions posted on tweakxp.com. So I've turned off some services and made other System Performance modifications. I'm not sure whether this information is helpful but it seems appropriate to mention.

Error messages.
Windows could not start because the following file is missing or corrupt:
<winnt root>\System32\ Ntoskrnl.exe.
Windows NT could not start because the following file is missing or corrupt:
Winnt_root\System32\Ntoskrnl.exe
Please re-install a copy of the above file.
ntoskrnl.exe is the NT Kernel & System.
ntoskrnl = NT Operating System Kernel.
ntoskrnl.exe is the core (also called the kernel) of the Windows NT
operating system.
[[The kernel is the central part in most computer operating systems because
of it's task, which is the management of the system's resources and the
communication between hardware and software components.
As a basic component of an operating system, a kernel provides abstraction
layers for hardware, especially for memory, processors and I/O that allows
hardware and software to communicate. It also provides software facilities
to userland applications such as process abstractions, inter-process
communication and system calls. ]]

All computers running Windows NT share the same startup sequence:
* Power-on self test (POST) phase
* Initial startup phase
* Boot loader phase
* Detect and configure hardware phase
* Kernel loading phase
* Logon phase
Without ntoskrnl.exe Windows is worthless.

Wow!!!
I'm in deep sh*t. Damn, I had the system so prepped. I'll begin
brainwashing myself into thinking that I might just have to clean install
everythinggggggggggggg. It was so much work.

It means that the partition doesn't exist anymore. You have to create a new
partition in the unallocated space, format the partition, then install
Windows.

Scooby,
I appreciate the info. but something in me tells me that there is another
way. Especially when I have a good backup copy of the file in the same
directory. There must be a way to get into the drive so that I can simply
delete the bad file and replace it with the known, good one. I'll be sure
to let you know when I've unearthed it. Thanks again.

The bad file is a minor problem. You somehow have deleted the partition so,
unless you know how to fix it, you'll have to partition the drive and format
the partition.
