Windows 7: xp and windows 7 dual boot

xp and windows 7 dual boot

i am trying to dual boot windows 7 with xp. Windows 7 is allready installed on my machine i have created a iso boot disk using nlite with windows xp pro service pack 1 and have slipstreamed the required drivers(I THINK ) and service pack 2. When i boot up my laptop from the cd it comes up with this error

iaStor.sys is corrupted

I have done a little research on the fault code and have came up blank. Can any body help me by identifying this fault and how i would go about amending it and getting the machine up and running on both xp and windows 7

if you would like any further information just ask

many thanks.

Likely a problem with the slipstreaming. Rebuild the ISO and try burning it at slow speed with Verify using the drop-down menu on same page where ISO is created.

If error repeats: Unless you were prompted for the drivers during install, might as well wait til after install to provide any missing in Device Manager. A single driver can mess up slipstreaming.

If you remove the drivers and it repeats, then you may need to do over the SP2 slipstream, or try SP3.

If you are going that way, why don't you use SP3 to slipstream? There are several sites to show how to do this and it might fix your original problem at the same time.
