Mythril Posted October 19, 2010 Share Posted October 19, 2010 Hi guys. Quick question. I bought a Corsair P64 SSD a little while ago. All was fine until this evening. Within the BIOS I have had my hard drive settings set to AHCI and not IDE due to running a SSD. I have four other SATA HDD's within the same case. It's been fine for several months and now it refuses to boot into Windows 7. Now if I set the BIOS to IDE, the system boots :bigeyes: I can't get my head around it. I've tried unplugging all of my other HDD's including the CDROM, but no luck. I've even updated to the lastest BIOS just incase. So my question is, how come I can no longer have my BIOS set to AHCI ?

Synbios Posted October 19, 2010 Share Posted October 19, 2010 When you change it to AHCI then when you boot windows you get a BSOD? If you can boot into IDE fine then go in to IDE then change the registry in the AHCI guide then switch back to AHCI. Link to comment Share on other sites More sharing options...
Mythril Posted October 19, 2010 Author Share Posted October 19, 2010 Hi. I can't get past the detecting HDD's within POST. I'll take a look at the reg settings. Thanks. Link to comment Share on other sites More sharing options...
Engmod Posted October 20, 2010 Share Posted October 20, 2010 I was having similar problems, I updated my BIOS and the problems went away. Derek Link to comment Share on other sites More sharing options...
Yellowbeard Posted October 20, 2010 Share Posted October 20, 2010 You cannot change from IDE mode to AHCI mode in this fashion. You have to change your registry first in the OS with the controller in IDE mode. There is a sticky in the SSD section for this. Link to comment Share on other sites More sharing options...
Mythril Posted October 20, 2010 Author Share Posted October 20, 2010 Welll after 12 hours of messing around I've finally got my system up and running. The original problem was due to a small partition on the SSD. Once this was removed Windows was able to start the installation. Another problem was that whenever you selected the SSD within Windows installation it would say that I was unable to install Windows on here. I tried setting the BIOS to IDE, RAID and AHCI mode but nothing wourld work. Finally after many a test with different ideas, hdderase sorted out the problem. I was now also able to see the SSD within Parted Magic as I was not able before. Windows installed in AHCI mode and everything is working fine again. Least it's working now. Thanks guys for your help and support :) Link to comment Share on other sites More sharing options...
