Windows 7 - Error 0x80070241 - One success story

This appears to be a somewhat common install error and it happened to me.

Searched and discovered multiple _possible_ hardware and software causes and multiple _possible_ resolution schemes.

The only consistent solution regardless of all other factors was a boot from the Windows 7 install media; DVD, USB, etc....

Necessitates a temporary BIOS change to make the Windows 7 media the 1st boot media.

Me: Dell Optiplex/P4 3Ghz/2GBmem, XP Pro sp3, Windows 7 to be installed on a clean fresh dedicated 75GB drive.

Failure History: multiple downloads, multiple DVD burns at various speeds on multiple drives and multiple media mfrs, copied to new drive, ISO busted to new drive - Install always started in Windows environment and always failed with Error 0x80070241.

Success: Reset BIOS to boot from DVD, seamless install from DVD, 1st time.

Observation: On some hardware/software configs, in some obscure corner of Windows there sometimes exists a process/dll/driver/etc.... that creates a conflict with the Windows 7 installer; run the installer in a 'non-windows' boot and no conflict.

Welcome to Seven Forums J7000,

I'm in LA too..

Are you using a JMicron SATA controller? In this case , you should set AHCI in RAID config in BIOS or it won't work, so I read somewhere.
