How To Use the PUSHD Command to Access a UNC Path at a Command Prompt

To use the pushd command, type the following line at a command prompt, where uncpath is the UNC path for the network share that you want to use:

pushd uncpath

For example, to connect to a share named Sharename on a server named Servername, type the following line, and then press ENTER:

pushd \\servername\sharename

The pushd command creates a temporary drive letter that points to the network share, and then changes the command prompt to that drive letter. 

You can use the pushd command several times in one session. This creates a list (or "stack") of folders. You can type pushdwith no path name to view the current state of the stack. 

Windows could not start because of a computer disk hardware configuration problem

To resolve this issue, use either of the following methods.

Method 1

Edit the Boot.ini file to restore or correct the Default entry and to ensure that the other entries in the [Operating Systems] section of the Boot.ini file point to the appropriate directories.

For more information about how to edit the Boot.ini file, click the following article number to view the article in the Microsoft Knowledge Base:

289022 How to edit the Boot.ini file in Windows XP

Method 2

Use the Bootcfg utility in the Recovery Console to correct the Boot.ini file:

1. Use the Windows XP CD-ROM to start your computer.
2. When you receive the message to press R to repair Windows by using the Recovery Console, press the R key.
3. Select the Windows installation that you want, and then type the administrator password when prompted.
4. Type bootcfg /rebuild, and then press ENTER.
5. When the Windows installation is located, the following instructions are displayed:
   Add installation to boot list? (Yes/No/All)
   [Type Y in response to this message.]
   
   Enter Load Identifier:
   [This is the name of the operating system. Type Windows XP Professional or Windows XP Home Edition.]
   
   Enter OS Load options:
   [Leave this field blank, and then press ENTER].
   After you perform the preceding steps, restart the computer, and then select the first item on the boot menu. This should allow Windows XP to start normally.
   
   After Windows XP has successfully loaded, the Boot.ini can be modified to remove the incorrect entry.

   For Multi-Processor systems:
   expand <cd-drive>:\i386\ntkrnlmp.ex_ <hd-drive>:\Windows\system32\ntoskrnl.exe
