Before getting a SSD and installing Windows on it, I had Windows installed on a HDD and the SATA ports were set to IDE.
Previously to installing Windows on the SSD, I unplugged all other hard disks and set the SATA ports to AHCI, then installed Windows then plugged the other HDDs back.
Now, if I leave the SATA ports to AHCI and try to boot from the old Windows installation, I get a blue screen instantly.
My question is: do I always have to toggle the SATA ports in BIOS between IDE and AHCI depending on what drive I want to boot from (new SSD or old HDD) or is there a way to leave it to AHCI and have both installations work?
Would modifying the registry on the old Windows installation while in IDE mode work so I can boot without issues in AHCI mode after a restart?
