The information in this article applies to:

Microsoft Windows NT Server versions 3.5, 3.51, and 4.0
Microsoft Windows NT Workstation versions 3.5, 3.51, and 4.0

SYMPTOMS

When you are trying to install Windows NT, you may experience any of the following symptoms:

When you boot from the installation disks, the following error message may be displayed when disk 2 is inserted:
```
      Stop 0x0000007B Inaccessible Boot Device
      (0xFF109C50, 0x00000000, 0x00000000, 0x00000000)
```

When you are attempting to create a set of installation disks using the WINNT /ox or WINNT32 /ox command, the following error message may be displayed:

      This floppy disk is not formatted as high-density, not formatted
      with a standard Windows NT or MS-DOS format, or is corrupted.
      Setup is unable to use this disk.

CAUSE

You are using a LS/120-type floppy disk drive.

RESOLUTION

To work around this issue, install Windows NT Workstation with the /b switch. This causes Windows NT Workstation Setup to run without requiring the installation disks.
