  I have the same problem and i receive from dell suport this message: You will need to install the Sata Driver. On one of the setup screens is an option to install drivers on the lower right side of the screen. Choose this option and put the Dell Driver disk in. The driver it is looking to install is the Intel Matrix Storage Driver. If you need to download this driver and put it on a disk you can click the title below. Another way to complete the install without first installing the driver is to change the bios setting to ATA. To do this restart the system and press F2 to enter setup. Once there you can TAB down to Onboard Devices and hit Enter. Then tab down to SATA Operation. You will then see at the top of the screen on the right side ATA and AHCI. Change this to ATA. Save the changes and exit out. Once the system restarts you should be able to complete the install. After the install and you have loaded the drivers you will need to go back into the bios and change the setting back to AHCI it worked for me      :emotion-1:
I am having a problem with the reinstallation of Windows Vista on my XPS M1730. I have gone through the entire installation but seem to be hanging on the Completeting installation page. My computer has restarted once and is now hung. It has a check mark beside Copying windows files and one beside Expanding Files and one beside Installing features and one beside installing updates. Now it is hung at Completeting installation? I have gone through this 3 times now. Any ideas?
