Problems Using LS/120 Floppy Disk Drive with Windows NT Setup

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.

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

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.
