Installing Windows 7 Home Premium from a generic setup disk, I received an error at the end of installation.

"Windows could not complete the  installation. To install Windows on this computer, restart the installation.' 

I can only imagine a sociopath writes the error messages because restarting the installation only brings one  back to this error message.

Googling the error message,  I found a fix. In the BIOS I changed the SATA operation from RAID to ATA. After doing this I was able to install Windows 7 with the generic disk.

My question is do I have to worry about switching the SATA Operation back from ATA to RAID? Is this going to cause any issues later?
