KB101863 - Setup Does Not Clean Up After Failing

SUMMARY

When Windows NT Setup fails, the following may occur:

Setup leaves behind Windows NT boot code that causes the boot loader to bypass the boot selection menu on the first boot of Windows NT and go straight into the graphical mode of Setup. This is a problem if the system fails when attempting to go into graphical mode. You can get back to MS-DOS or OS/2 by holding down the SPACEBAR as the system comes up and then choosing Restart Computer at the Configuration Recovery menu. Then choose MS-DOS. You can edit BOOT.INI and change the time-out from 0 to something higher or change the default parameter to "c:\" which, with a time- out of 0, causes the system to boot straight into MS-DOS. For example:
```
      [boot loader]
      timeout=0
      default=c:\ 
						
```
Setup (WINNT.EXE) copies several megabytes (MB) of data into a directory called \$WIN_NT$.~LS on a partition it chooses. Setup should delete this, but if it does not, you can delete all of these files yourself.
Setup, in text and graphical mode, copies many files into the Windows NT directory (\WINNT). You can delete these files if you can get to them (for example, on a FAT partition, from MS-DOS).
