I'm trying to run an HD repair software during boot but it won't continue as my HD is in ACHI mode. The only way I can run it is to change it to IDE mode. I tried going into BIOS to change this setting but I don't see any option to change it at all! There isn't even an Advanced Setup option in BIOS.
ACHI is enabled by default in the BIOS. There is no way to change it to anything else. You can go into the Device Manager / IDE ATA/ATAPI controllers and click on the > on the left side. It will show you what is available.
