Windows 7: Windows cannot parse the unattend answer file's <DiskConfiguration>...

Windows 7 Ultimate x64
Windows cannot parse the unattend answer file's <DiskConfiguration>...

Hi there.

I'm trying to do a clean install of Windows 7 Ultimate on a Sony Vaio AR41s via a DVD that I burned (slowest speed, was very careful about that) but upon starting the installation I get the error message:

Windows cannot parse the unattend answer file's <DiskConfiguration> setting

After closing this dialog box the laptop reboots and starts the process from scratch.

The Vaio has nothing on it as far as I'm aware (No OS found etc...) so I'm pretty sure this is as clean a install as I could do.

Here's the specs of the AR41s:
CPU - Intel Core 2 Duo T7500 @ 2.2 GHz
Cache Memory - 4 MB - L2 Cache
RAM - DDR II SDRAM - 667 MHz - PC2-5300 ( 2 x 1 GB )
HDD - 2x 160 GB - Serial ATA-150 @ 5400 rpm
Optical Storage - BD-RE
GPU - NVIDIA GeForce 8600M GT - 256 MB
OS - N/A

Running the 2x160GB HDDs in RAID 0 configuration. I tried de-RAID'ing the HDDs to see if that was the problem but I get the same result.

I've done some research on the internet and there's a lot of talk about xml files and whatnot but I can't see how I'm going to access anything given that there's nothing on the machine.

This is my first time trying to install a new OS on a machine so right now I'm a little lost.

If there's any other information that I should have given then do please mention it and I will edit my post accordingly.

Any feedback would be much appreciated.

Hello farouche, welcome to Seven Forums!

Where did you get the Windows 7 ISO file you burned to DVD? This sounds like the real issue.

Leave the RAID broken, Windows 7 has issues with RAID anyway.

Check the PC BIOS to make sure it is set to ACHI and not RAID or IDE mode.

Then do a complete wipe secure erase to the entire single Hard Disk Drive (non RAID) and then create a 100GB partition to do the install to and start the clean install, have a thorough look through the information in these tutorials linked below and be sure to post back with any further questions you may have and to keep us informed.
