enabling AHCI Mode in BIOS causes boot failure

elliottmarter · 7 Feb 2013 at 14:30

Currently using Samsung 830 SSD 128GB, in the new Samsung magician software V4 it advises me to enable AHCI for "best SSD performance" but when I go in to BIOS and change the setting from IDE to AHCI it does get to the "windows is loading" screen faster but then fails to boot and tries again, changing it back to IDE stops the problem and it boots just fine again just a lot slower

any ideas?

Windows has already been set to use ahci. Quite a common mistake and i've done this many times.

Here's how to get round the problem :

You needed to set AHCI before doing the OS installation. Fear not there is a way to get around it.

If you reinstall windows7 you should have no problems, however if you're using Win XP you're going to need to do what I initially did.

This for me as it will be for maybe you unfortunately, I spent hours on end searching the Motherboard installation disk to find the appropriate AHCI file which then will need slipstreaming to Win XP installation files, thus creating a new XP installation disk

If you're lucky enough to have a floppy drive, you can copy the ACHI file to a floppy disk and at the appropriate time Hit F6 during XPs installation.

I might be telling my Granny how to suck eggs here, if so I apologise in advance

if you cant be bothered with reinstalling or registry "hacking" a simply sysprep should do the trick and is extremely easy to use
