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.
