Hi so I have a Dell xps 400 with windows media center 2005.

On startup I get a bsod and on the bottom it says there's a IASTOR.SYS error. I did some research and found that I need to change the Sata operation from RAID Autodetect / AHCI to RAID Autodetect / ATA in System Setup.

But when I do this I get a unmountable_boot_volume bsod.

I then searched and found I should put the xp cd in and run the recovery console but my computer wont boot from the cd rom or usb. (Yes I changed the boot sequence)

Any advice? :(


once I get booted up I am suppose to get the updated drivers then switch back to RAID Autodetect / AHCI. (I think) :|


@Allan, Nothing is new just randomly started doing this. Newest thing would probably be little things like installed malwarebytes/Chrome couple weeks ago.

What is new or different since the last time everything worked properly (ie, new hw, new sw, virus, error, etc)?

IASTOR.sys BSOD's can be caused by Malware, but to make sure you are not infected you would need to post in the Malware Removal section. Also IASTOR.sys is a driver associated with Intel based motherboards. Since you are getting the unmountable_boot_volume I would go and make the changes in your BIOS to let Windows see the SATA Drive as an IDE one. Sometimes Windows has issues booting from a SATA Drive

What are you trying to accomplish?

<<On startup I get a bsod and on the bottom it says there's a IASTOR.SYS error.>>

Please post the entire error message, not just what you think is important :). It's all important.

<<I did some research and found that I need to change the Sata operation from RAID Autodetect / AHCI to RAID Autodetect / ATA in System Setup.>>

Can you post a link for this "research"? The ultimate authority on BIOS settings...is generally your system manual or motherboard manual.

<<But when I do this I get a unmountable_boot_volume bsod...>>

Does that mean that...when you don't change the BIOS settings...the system boots...or does it just mean that you don't get the Unmountable Boot Volume error...but you get another?

<<...but my computer wont boot from the cd rom or usb. (Yes I changed the boot sequence)...>>

Are you following Dell instructions?
