Can't delete ext. partition w/FDISK or load NT Server

Here's the problem:
I had a dual boot system (98/NT Server). NT crashed and won't allow me to recover or run the setup.  I get something along the way of a "Page Fault In Non Page area" along with a memory dump.  as soon as I indicate support for large hard drives (27GB) - crash!  Windows 98 installs just fine.

FDISK indicates that I still have a 19GB extended DOS partition.  If I try to delete it the partition FDISK indicates that there is a logical drive that must be deleted first.  When I try to delete any logical drives, FDISK indicates that no logical drives exist.  

I attempted to run PartionMagic from Win98, but when I try to view partion information I get the following error: "Access violation at address 004415E3. Read of Address FFFFFFFFF.

There's no data to be saved so wiping the entire harddrive clean is as good a solution as any, I can't get rid of the partition I can't format the hard drive as one 27 GB drive either.

Any takers?  Any suggestions on how to wipe out the partition or reformat the entire drive and wipe out any partitions at the same time?

Well, since you tried partition magic, I'd suggest looking for an Update to partition magic or just download a linux set of boot disks and use linux's fdisk program - it's much better at handling partitions than anything Microsoft ever came up with.  
debug the master boot record, this will clear all partition information if the disk is still good.

Clearing The Master Boot Record
Use This Routine When:

FDISK does not recognize the hard disk and NO hard disk error messages appear on POST such as "FIXED DISK 0 FAILURE".
There is a virus on the master boot record of the hard drive (in this case a DOS format will not remove the virus). This particularly applies when virus detection programs cannot eradicate the virus. A cold boot is necessary after this is done to clear the virus from memory and prevent it from writing to disk. Follow this with a FORMAT C: /S/U.

There are non-DOS partitions to be removed. This is will remove all partitions on the hard drive including any existing DOS partitions.
Using Debug


1) Open an MS-DOS Command prompt.
2) Type DEBUG and press Enter.

what you will see          what you enter
-                                 FCS:200 400 0
-                                 RAX
AX0000                       0301
-                                 RBX
BX0000                       0600
-                                 RCX
CX0000                       0001
-                                 RDX
DX0000                       0080
-                                 E100 CD 13
-                                 P
-                                 Q

if you want a description of what this does, let me know but it will work.  you will then have to use fdisk to recreate partitions ( or third party disk manager ).

by the way, it is best to cold boot to DOS to run this.
when restarting, continually hit F8 to get to the start up menu and choose command prompt only.


Good Luck!!!
also, please make sure you have a boot disk since you will have nothing on the system!!!

probably obvious but if I didn't mention it, I'd feel bad!
Go to your hard drive manufacturers site, and download thier version of ontrack's disk manager or similar, then use the "low level format" option in that, it's not really low level in the original sense of the term, but it will return the drive to original specs and clean it up.

Upgrade to Version 5 of Partition Magic.
Then, use it to recreate a pair of "bootable" diskettes.
Boot the first diskette, switch to the second diskette when prompted, and a "skinny" version of Partition Magic will run.  Use it to delete drive-letters and partitions.
Try to download "XFDISK". You will get a small BOOT-MANAGER and some other features for free and your major problem of inaccessible partitions should be gone. For me it worked fine since you can create several primary partitions.
Load with a copy of DOS ver 6.22 and use its Fdisk.  This will clear your NTFS partition.  Then boot with Windows 98 boot disk so you can use the FAT32 partition and take advantage of the 27Gig.

what's the status here?

Rumour has it that Sylvar was kidnapped by space-aliens, and will never return to respond to your question.
no!  he's hanging with Elvis and Jim Morrisson.  He'll be back just like them.
