It
seems like a precarious situation and possibly the first time in a while to have
experienced such an error. When the setup of Windows has loaded some
system files only to be presented with an error message just right
before the screen of partitioning the hard disk drive, 'Fastfat.sys is missing or corrupted' . Options beneath are nothing other than to Esc to restart or insert an installation disk to upgrade.
For
a while it has taken more attempts to rectify the error by following
instruction as presented on screen yet without success. The installation
disk seems to be working fine and all information on internet have be
exhausted. Now, it is becoming wait-for-epiphany idea, more like a
believer's thing.

Fastfat.sys
reviews have no much explanations for the function of this file. Many
information available online are concerned about the causes and how to
forestall the error message. Pointing to the importance of this system
file in Windows operation, it seems to be having some kind of
relationship with the RAM (Random Access Memory)of a system making it
subjected to how important a process is accessed by the present of this
file. A closer look introduces one to FAT(File Allocation Table), that
is an original disk format used by Disk Operating System(DOS), which
this Fastfat.sys is a system driver for it. Instead of just naming it
FAT.sys due to the way it evolved the driver is named Fastfat.sys. It
can be found inside the drivers folder of the system32 sub-directory of
the Windows main directory.
However,
there are consequences of this error message, that is the installation
can not proceed without it due to the nature of how it is hardwired into
the Windows system. There are two things to take note of while looking
for this particular file, either the file is actually missing or
corrupted and it can be a hardware responsible for the error. Whatever
that may be, there is always a solution to the problem.
(a). The File is Missing or Corrupted
Step 1: Get a genuine Windows Installation Disk.
Step 2: Start the installation from the beginning.
Step 3: If you are still experiencing the trouble follow the instruction on Microsoft Support Website to resolve it.
(b). It is Hardware-related Problem
Step 1: Turn off the system before proceeding with it to the next step. Probably jot down the steps before turning the system off.
Step 2: Open the system and check for bad or damaged RAM and change it.
Step 3: To check for damaged or dead RAM remove all the RAMs and test them one by one to see the one with the fault.
Step 4: Look
closely at the golden connectors of the RAM to see if any of them are
out of place. If there is damage due to pulling or inserting it into the
slot, then try to be careful in placing the new replacement in the
rightful slot.
Step 5: Restart the system and continue with the Windows setup.
