Is it just plain not possible to boot from a CD/DVD drive that is set in BIOS as SATA/AHCI mode? I can acces the drive & read/write from it, it just won't boot to it. Yes I have CD/DVD drive set as 1st boot drive. I have "Googled" the earth & can't seem to find a straight answer to this. Can anyone enlighten me on this topic?
Thanks, Jim
The controller settings shouldn't have any affect at all on it's ability to boot. My controllers are always set to AHCI and are left that way.
If you are trying to install Windows, a simple work around would be to use a USB flash drive. I can't remember the last time I've installed Windows from a disc.
I'm not trying to install Windows. I'm just try to boot from a bootable cd to run an antivirus scan. When I change the mode back to IDE from AHCI I boot from the CD/DVD drive just fine. I'm just trying to get ALL drives to run in AHCI. The HDD's work just fine in AHCI.
Thanks allot for your reply though. It's much appreciated. Anyone else got any ideas?
You wouldn't be hurting anything if you switch to IDE just for the boot disc, but I can see that as being a pain if you do it often. Is there a BIOS update for your mobo, or have you contacted the manufacturer?
As another thought, maybe your specific boot disc has issues with AHCI. Have you tried other boot discs, such as Windows ones, just to see if the problem is that disc or overall?
Is your optical SATA or IDE?
If its an IDE drive, and your bios is set sata/ahci, that may be it.
On some motherboards a set of ports can be set to SATA or IDE in the BIOS. If your motherboard/BIOS supports this, then set these ports to IDE and plug your optical drive into it. I have seen people setting it to SATA and complaining that they are unable to boot.
Can't Boot from CD-ROM in AHCI mode
OP, what motherboard do you have?
Mobo is a Gigabyte GA-990FXA-UD3, BIOS Version F9
