You can  install  it directly from your DVD-drive (from My Computer) but what  if  your OS gets corrupt? At that point of time, you’ll require a bootable CD.

Now here are the steps to create a  bootable CD  from a non-bootable Windows XP iso:

1. First insert a blank CD and  mount your Windows XP iso image using  Magic disc or  some mounting  software.
2. For creating a bootable CD you’ll  require  boot file  known as  boot.ima . Download it from  http://www.mediafire.com/myfiles.php
3. Open  Nero Burning Rom 8 or 9  and select CD-ROM(boot) on the left side.
4. Click on Boot tab, browse to the boot image file boot.ima, then select Enable Expert Settiings.
5. Now Change Kind of Emulation to No Emulation and  Number of load sectors to 4.



6. Now  click on  ISO tab. Select Mode 1 in data mode, select ISO 9660+Juliet from File System, Max of 31 Chars from file name length and ISO 9660 from character set.Also check all in  relax restrictions



7. Click on the label tab and give any name  for your cd.
8. Now click on new at the bottom, browse the Windows XP image and  select all contents of image on the right panel.



9. Now  copy  and  paste the  selected  items into  left  panel space.
10. Click on burn.

Simple wasn’t it?

Note: The following tutorial assumes that your Windows installation directory as well as Internet Explorer has been installed on the C drive. If not, just change the drive letter.

Well its pretty simple, just enter the following in the RUN text-box:

C:\Program Files\Internet Explorer\iexplore.exe

Huh, don’t you think it’s pretty long? Well there’s a simple work-around. You need to do the following steps (just once).

1. Just go to the the RUN box again. (Keyboard Shortcut : Win + R)
2. In the text-box type:
   

   C:\Program Files\Internet Explorer\

3. Copy the file named ‘iexplore’ or ‘iexplore.exe’
4. Again open the RUN box (Win + R)
5. Now in the text-box type:
   

   %systemroot%\system32\

6. Now just paste the the iexplore file (which we had earlier copied) in this folder.

That’s it your done! Now to open Internet Explorer from the RUN box, just open it up and then type ‘iexplore’ (without quotes). How’s that!

You could do the similar for Firefox (firefox.exe) or any other related software.

So it’s very important that you disable auto-run in your PC’s quickly. Use the appropriate method according to your OS, and perform it:

1. The easiest and most effective means to truly disable autorun can be done via this simple autorun registry hack:REGEDIT4
   [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping\Autorun.inf]
   @=”@SYS:DoesNotExist”
2. To use this method, Open Notepad and copy/paste the following into a text file:REGEDIT4
   [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping\Autorun.inf]
   @=”@SYS:DoesNotExist”Save the file as something.reg. (You have to be sure to change the “Save File as Type” to “All Files” before saving, or Windows will try to save it as a .txt even if you typed in .reg.
3. Locate the file you just saved and double-click the file to run it. You will receive a prompt asking if you want to add the data to the registry. Click yes to allow the modification.
4. The above method nulls any request for autorun.inf and works on XP Home or Pro, as well as Windows Vista. Credit for this tip goes to Nick Brown.If you opt to disable autorun using any other method, you will first need to install an autorun patch from Microsoft that allegedly resolves issues that cause autorun to run even after it’s been disabled (using methods other than the above recommended method).
5. XP Pro users who have installed the appropriate Microsoft patch for your system and wish to disable autorun using a method other than described above, follow steps 3 through 8 only. XP Home users begin at step 9. Vista users, see How to Disable Autorun in Windows Vista.
6. XP Pro users: Click Start and then click Run. Type gpedit.msc and click OK. The Group Policy window will open. In the left pane, double-click Administrative Templates
7. the right pane, double-click System, scroll down the list and double-click Turn Off Autoplay
8. the Turn Off Autoplay Properties window, select Enabled. From the dropdown next to Turn Off Autoplay on, select All drives and then click OK. Exit Group Policy by selecting File, then choosing Exit from the menu.
9. Home users will need to make the changes by editing the registry directly. To begin, click Start and then click Run
10. regedit and click OK. The Registry Editor window will open.
11. the left pane, navigate to:
    HKEY_CURRENT_USER
    Software
    Microsoft
    Windows
    CurrentVersion
    Policies
    Explorer.
    (Note: For help navigating the registry, see the Windows Basics System Registry tutorial).
12. Explorer highlighted, in the right-pane right click the value NoDriveTypeAutoRun and select Modify from the drop down menu. The base value will be set to Hexadecimal. If not, select Hexadecimal.
13. 95 and click OK.
    Note that this will stop Autorun on removable/USB drives, but still allow it on CD ROM drives. If you want to disable autorun on both, substitute b5 for the 95. (Thanks to Ian L. of Manitoba for the tip).
14. Registry Editor by selecting File, then choosing Exit from the menu.
15. will now need to reboot your computer for the changes to take effect.
