Cx26C and Cx221 stop errors during setup re-boot

OK, I have the following machine:

Tyan Tomcat I board w/ 150+ Cyrix
Seagate IDE Drive
  - single partition (tried FAT and NTFS)

I am able to load NT 4.0 WS well using the disks -- it finds
my hardware successfully, and it loads files from my CD-ROM
to my IDE drive successfully(?). At this point, I am prompted to remove floppies (and CD-ROM) to re-boot the

Computer re-boots, but then I get one of the following

(Using NTFS)
1. stop1. Stop: C000026C {Unable to load device driver}
   \??\c:\winnt40\system32\win32k.sys device driver could      not be loaded
   error status was 0xc0000221
   restart and set the recovery options in the system       control panel or the /crashdebug system start option

   I roboot again, getting

2. Stop: C000026C {Unable to load device driver}
   \SystemRoot\System32\Drives\qv.sys device driver could    not be loaded
   error status was 0xc0000221
   restart and set the recovery options in the system       control panel or the /crashdebug system start option

Then reloaded NT, this time formatting partition as FAT

1. Stop: C0000221 {Bad Image Checksum}
   The image oleaut32.dll is possibly corrupt

   I reboot again, getting...

2. Stop: C0000221 unknown hard error

   I reboot again, getting...

3. Stop: C000026C {Unable to load device driver}
   \SystemRoot\System32\Drives\NDIS.sys device driver could    not be loaded
   error status was 0xc0000221
   restart and set the recovery options in the system    control panel or the /crashdebug system start option

So, it asks me to place new files in non-existant directories. (And, of course, this requires that I use a
FAT system so I can copy over new files with a floppy. And
of course, this presumes that I have another computer to
copy files from a CD).

Anyways, I know c0000221 errors (according to MS) are due to
corrupted files, but I have tried probably a dozen different installs (on FAT and NTFS) with same error codes, and I have
even tried different CD ROMs and serup disks, so I know the
media is not a problem.


Edit to above question by mlopez 06 Feb 97 9:33 PST--->

Yea, have already tried fdisk-ing drive several times. I did
have some limited luck when I partitioned the drive into 2
partitions with less than 1 GB each, lets me occasionally
get into NT (but only about 20% of the time). But everytime,
I get the following error in event_log:

event id: 26
Application Popup: System
Process: Unable to load Device

Drive \SystemRoot\System32\Drives\rdr.sys device driver
could not be loaded. Error Status was 0xc0000221

Although these partitions were formated in NTFS, I guess I
could try two partitions in FAT, but not very hopeful that
would make a difference? Drive (in fact entire) computer is
brand new, each component straight from the manufacturer, so
I think virus idea is unlikely (plus, I have only used
virgin 6.20 and NT disks in my install... I'm careful about

By the way, during one of my many re-boots, I did get the
message that srv.sys file could not be loaded -- in addition to the rdr.sys file -- any ideas? I'm also pretty certain the drive is OK, every Symantec scan I do looks cool...

I don’t think the issue is Fat or Ntfs.
But if it was me, I would load Fat.
You can’t lock your self out seven ways to Sunday with NTFS with some problems.

Try the following :

1) Virus scan your system.. I just worked on a system were Windows NT would not load because of a Boot sector virus. so...
2) With a Msdos boot disk preferably 6.20 or later delete the partions and re set them up.
3) After rebooting type the following fdisk /mbr. This will rewrite your master boot record on the hard drive.
4) If you are still having problems loading NT. Try a program like Norton disk doctor and have it look at your hard drive.
5) If you still having problems or if norton finds something and can’t fix it. It may be time for a new Hard drive.
