Removing NT4
I have a laptop that someone tried to remove nt 4 from. When I do fdisk I can only see 1 partition and it said it is 5.3 gig with 56% useage. This laptop has a 10 gig hard drive on it. It will let me go to the c: but I cant look in itto see any files. I want to install windows 98 on this system but it wont allow me to. I would like to see if I have partition I cant see on this drive, and if I could remove them.
Thanks Ed

Insert the boot disk in drive A:,at command type fdisk
In the fdisk panel choose option five to view drive
the drive partition is possible in NTFS,so you will not be able to see the extended drive from Win 98
Note the drive letter and hit escape,choose to change drive option,now go back to first panel and choose to delete non-dos partition and the then choose to delete extended dos partition,if this works then remember to go back and change the drive back to (1),follow the on screen instructions

I went to fdisk and it only has 1-4 no 5. When I display partition information option #4 it showes the extended dos partition contanis logical dos drives. When I hit yes to show the drive information it comes back no logical drives defined.

Regardless of what you see in the information screen, the easiest way to fix this problem will be to completely repartition the drive. Just remove any DOS and/or non-DOS partitions - the NT partition, as soulrider said, is probably NTFS and will show up as a non-DOS partition. Once you have the original partition(s) removed, you can repartition the drive and start over with formatting and loading the OS. BTW, be sure the boot disk that you're using to run fdisk and format is a Win98 boot disk, not earlier Win95. Otherwise, you won't be able to create any partition greater than 2GB or format with FAT32. Hope this helps!

fdisk for windows98 would not remove partitions created by NT in NTFS format to delete those partitions you need the start up disks from NT or the NT Cd . You can create the disks by running winnt /? and pick the right / to create the disks reboot the computer and folow the prompts until you get a chance to delete partitions after that F3 to quit the NT setup.

Use DEBUG to remove any and all partitions from the hard drive.
Boot with a 98 Startup that has DEBUG.EXE on it. It is located in the Windows\System folder if you need to copy it.
At the DOS prompt, type "debug" (without the quotes) and press enter. You will get a dash (-) for a prompt.

CAUTION: Performing the following will remove all data from hard disk.

TYPE: A CS:100 [ENTER]
you will have xxxx:0100 returned.
TYPE: MOV AX,301 [ENTER}
you will have xxxx:0103 returned
TYPE: MOV BX,200 [ENTER]
you will have xxxx:0106 returned
TYPE: MOV CX,1 [ENTER]
you will have xxxx:0109 returned
TYPE: MOV DX,80 [ENTER]
you will have xxxx:010C returned
(NOTE: "80" for hd0, "81" for hd1)
TYPE: INT 13 [ENTER]
you will have xxxx:010D returned
TYPE: INT 20 [ENTER]
you will have xxxx:010E returned
TYPE: G [ENTER]
you will have "Program Terminated Normally" returned.

That will remove any and all partitions on the drive...
