Windows 7: Trying to dual boot 2 windows 7s

Reboot and enter BIOS setup to check SATA controller setting. That error can be caused by the controller being set to RAID. If set to RAID you may need to provide the RAID drivers.

Next check the UEFI settings in BIOS, including Legacy BIOS and CSM. You may need to set it to a Compatibility Mode to install.

Is there a newer BIOS update?

Is this an Advanced Format HD (AF logo?) which may require a BIOS update?

Are there performance issues with the extant Win7 which might point to HD issues, or a bad SATA cable?

Are you using the new DVD, or a flash installer which may need to be removed before reboot, with HD set as first to boot in BIOS setup?

If using flash or burned installer, try another official ISO for your licensed version burned to DVD or flash stick using tool in Steps 1 and 2 of Clean Reinstall - Factory OEM Windows 7
