Hardware Drivers :: AHCI Mode - Del Key To Get Into BIOS Not Work?
Mar 3, 2013
Ever since switching to AHCI mode, I've noticed that my keyboard has issues with the volume wheel not working properly. Also after setting up the LED lighting on the keyboard and a few restarts later, I've notice that when restarting my system the keyboard LED, blue in this case, will automatically show up and when it does, and I use the del key to get into BIOS doesn't work. I have to move the the usb connection to a different port, restart and keyboard LED will be white. This time using the del key, I can get into my BIOS no problem. This never happened when I was using native IDE mode.

A couple of weeks ago, I cloned my HDD C drive to a new 250GB Samsung 840 EVO SSD.
After fitting the SSD in place of the old HDD, the system rebooted fine and worked well with a very noticeable increase in the speed at which Windows loaded.
However, Samsung's "Magician" software informed me that the drive was running in SATA mode and that better performance would be obtained by switching the Storage Configuration parameter to AHCI mode in the BIOS on my ASUS P7P55D Pro motherboard.
So, I tried this but Windows would not load. I didn't get a BSOD as such... I'd get the Windows 8 start-up logo with the spinning dots below for a while, then the screen would go blank, then a message would flash briefly on the screen saying something along the lines of "Windows has experienced a problem and was unable to start so your computer is being restarted" (not exact words as it's not on screen long enough for me to read) and my computer reboots. This startup/error/reboot loop is repeated until I enter the BIOS and switch Storage Configuration back to IDE whereupon all is back to normal.
Further research then revealed that I needed to tweak the registry so I did this but I still get the startup/error/reboot loop.
Next I tried booting into SAFE mode as described in this thread. It'll boot fine if I leave Storage Configuration set to IDE but not if I change it to AHCI. It just goes back to the same old startup/error/reboot loop and Windows makes no attempt to install any new drivers.
I know I could do a clean install of Windows but I don't really want to go down that route if I can possibly avoid it.
I strongly suspect that the motherboard's Intel(R) 5 Series/3400 Series SATA AHCI/RAID Controller does not have the right driver installed that would enable AHCI mode to work. Is there a way that I can force installation of an updated driver? Is there such a thing (device manager tells me the latest driver is installed)?
I can live with IDE mode as the computer boots considerably faster from the SSD and programs load much quicker too but not being able to use AHCI mode is bugging

Windows 8 has suddenly stopped to recognise my friends keyboard. Mashing Shift-F8 seems to let the keyboard work (for several minutes). All drivers are up to date, works perfectly in Safemode and BIOS. I have reinstalled windows 8 (its only used for web browsing) and nothing has worked. It is a Toshiba Satellite.

i have recently bought an SSD. I have heard from a youtube video that changing the Sata controller from IDE to AHCI can give me better performance but i tried to enable this and it doesn't recognize the drive. The PC will not boot in AHCI mode which meant i have to switch to IDE again. I have tried booting from the Windows install DVD but it tells me that i cannot install Windows on this drive. Am i missing something?

I tried installing the 8.1 Intel SATA/RAID driver from the ASUS website P8Z68-V motherboard model, but when enabling AHCI in BIOS I'm getting blue screens which is making me think something isn't configured properly in the OS. How to properly enable this in 8.1 yet? I'd definitely like the extra speed out of my SSD

I just can't seem to get windows 8 to install/use the ahci controller - some specifics:
- new system
- clean windows 8 install (non-pro)
- one new ssd drive and one new hybrid drive, latest firmware flashed
- windows 8 installed on ssd (samsung 120gb)
- bios set to ahci+raid
- bios version current
- installed Windows 8 without pre-installing latest storage drivers during setup, ahci not recognized in device manager
- reinstalled Windows 8 using latest pre-installed drivers during setup, ahci still not recognized in device manager
Spent a lot of time researching this issue and none of the suggestions i've come across seem to work, including registry hacks. regardless of what i do Windows 8 just won't recognize my drives as ahci mode - ahci mode is setup in bios but Windows 8 still loads the ide drivers which can be seen in device manager under ata/atapi controllers. Why won't windows 8 recognize the bios ahci setting?
chipset - intel pch-c206
hp z1 server
latest bio update installed
cpu - e-1245
ssd (120gb) - operating system
hybrid drive (500gb) - storage
memory - 16gb

One day, I changed the configuration of IDE to AHCI through Windows registry and configuring the BIOS parameters. Today, I want to go back to IDE without reinstalling Windows. I do not know how to do.

So I switched over to the SATA setup via BIOS in attempt to improve my SSD performance. I knew I had to reinstall on the SSD but my I am not able to read or even format my second HDD that was also in AHCI. Is there any way to (would be awesome if) read, or at least format my drive so I can use it again? I tried disk management and other options within the OS and couldn't format.
it's an MSI 990xa gd-55 mobo. Which I am ashamed to even own because it sucks.

The OS is installed while the mode was set for IDE, and afterward it was changed to AHCI. Now, the system does not boot. "Attempting repair" is displayed and the process does not advance.
Windows 8 is installed on a ssd and a hdd, and both exhibit the same symptom.
The system includes GA-970A-UD3, FX-6300, DDR3 1866 4GBx2, 1TB SATA3 and 120GB SATA3 SSD.

Currently using Onboard RAID1 which is just a pair of 1TB SATA drives that boots into windows 8.1. SATA BIOS mode is set to RAID.
I need want to switch the onboard SATA mode to AHCI so I can boot to SSD, instead.
I'm sure some have tried this: If you just clone the RAID partition as it sits on to the SSD, it will not boot the SSD when the SATA Bios mode is set to AHCI.
So, besides a bare-metal reinstall, how do move my Windows 8.1 installation on to the SSD so that when its all done the SSD will boot into windows and the SATA Bios is in AHCI mode? I'm not opposed to purchasing software like Macrium or Acronis if any of those can do the job.
It seems like anyone using onboard RAID would have run into this problem after purchasing an SSD.

On my computer there is a pre-installed Windows 8 which works fine for UEFI boot (Secure boot not necessary).
Now when I switch in UEFI setup at boot time the UEFI mode into the CSM (BIOS) mode and restart then Windows 8 is not starting any more.
As far as I find out an UEFI-based Windows 8 can only boot with UEFI mode enabled.
So my question is: Can I turn an existing UEFI based Windows 8 installation into an CSM/BIOS based installation (=a Win8 which boots successfully even when I enable CSM in UEFI setup) ?
If yes: How do I do that?

I cannot install windows 8 in BIOS or UEFI mode.
it's getting boot and install only in EFI mode. after trying to reinstall it won't allow me to select the disk partition, as it gave me the error "
Windows 8 cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks." i tried all the given solutions on GOogle. even i cannot recover or refresh using windows 8 environment. many times it gives me BSOD. cannot vonvert to MBR as it says it cannot be done on virtual HDD.
tried many things nothing works, need to install windows 8 after every 1 or 2weeks, many a times my BCD data gets corrupt, and windows wont start. Also tried many things to repair this, but only thing that works is reinstalling windows 8.
That gpt or MBR error was solved by selecting UEFI:CD drive. in boot options by pressing F12 after inserting the disk.
My system configuration:

Windows update has been really messing with my pc lately. I ran update and when it installed the updates my integrated mouse ended up not working. I rolled back update and installed the updates one by one and the one I ended up not installing was the camera codec pack. Now the problem I am having is that my touchscreen won't work. If I talk to HP support they do the most basic thing they can and then when they can't fix it they tell me that I have to ship it to them because hardware is broken.

I'm an IT pro and I'm in the process of creating Windows 8 Pro (64-bit) images for my workplace using audit mode (i have done this countless times on windows 7). The problem is, the 'Change PC settings' button does NOT work when I click on it in audit mode. Nothing happens at all, the charms bar just slides away as it should, and then....nothing.
Heres what I'm doing:
1. Installing Windows 8 using our (MAK) dvd on my base image PC (Dell Optiplex 780). This is a CLEAN install on a wiped hard disk using verified installation media.
2. I Press Ctrl-SHift-F3 at the 'Personalize' screen to launch audit mode
3. The system logs in as it should with the built-in admin account
At this stage, Windows is not yet activated. The change PC settings button does not work.
I then:
4. Activate Windows 8 using the 'slui 3' command to input my volume product key. This activates OK.
5. I reboot to complete activation
6. I verify in system settings that windows IS activated.
The 'change pc settings' button still does not respond at this stage (nothing happens at all, no errors etc). And this is with ZERO changes to the PC.
Attempted Workarounds
For the record, I have tried countless things in a bid to fix this, including but not limited to:
* put the resolution to 1024x768 (as some forums recommended) - 'change PC settings' still not working.
* installing ALL available windows updates (before activation, after activation etc) - 'change PC settings' still not working.
* updated the PC bios and tried again - 'change PC settings' still not working.
* I have created new local accounts (admin and non admin) just to test it using the new accounts, and that doesnt work either.
* I have wiped the disk and attempted complete wipe and reinstalls countless times (and on 3 different models of PC), with the same result. 'change PC settings' still not working.
* tried countless possible fixes found in forums all over the web - none of which worked.
I have done all this and more, countless times, and in countless different orders to try and beat this thing, but to no avail.

I was initially very excited to hear that windows 8.1 allowed users to split the screen in any ratio they want (not just 80:20) in metro mode. However, no third-party apps seem to be compatible with this feature. Only Microsoft apps will expand to any ratios other than 80% or 20%. All third party apps will remain in the narrow 20% view even when you try to expand them to, say, take up 50% of the screen.

big problem for everyone who uses an SSD for the sytem drive and used audit mode to relocate Users to another drive. Is there a GA iso available yet?n Or a way to burn an iso from what we've downloaded from the MS Store?
This seems like a pretty glaring oversight now that MS is pushing to get rid of optical media. Things fail, often catastrophically (esp Windows).

A while ago I tried to put a new HDD in my laptop and got a message saying something a long the lines that the disk wasn't recognised (forgot exact message)
I took the computer to my computer repair shop and they installed the HDD I asked them if it would be easy for me to do it and they said yes it was just a case of resetting the BIOS.
how to reset the BIOS so I can install a new HDD?
I've installed HDD's in windows 7 machines and it was just a case of inserting the disk- I didn't have to mess with the BIOS!

I have a Lenovo G510 i7(which does not seem fantastically faster than my celeron Samsung R530!). I have replaced the DVD with a SSD. I have cloned the HDD to the SSD, made changes in the BIOS(changed to ACHI,switched to Legacy, put the SSD first in boot) but get the message "no bootable device insert disc and press any key". If I use UEFI I do not see the SSD. I have googled this until my finders are sore to no avail. How to boot from the SSD and once I can do this can I reformat the HDD? The SSD is called A:, the HDD C:. I cannot change the drive letters.

I have a Samsung DP700A3D All-In-One. It came preinstalled with Windows 8. I remember it being version 6.2 (?). I always seem to try things above and beyond my skill set (Current Computer Science student). I installed Ubuntu 13.04 64 bit alongside Windows 8 with no problems. I aloud the Ubuntu to do the partioning. It used Grub2 for bootloader. I wasn't happy with that wanting to use Windows Boot Manager. After changing this and reloading that, somehow the windows 8 partition did a recovery. I can now not boot anything. I'm currently on Ubuntu live CD. I can see the drives from here. There are partitions labeled SAMSUNG_REC, SAMSUNG_REC2, 487 GB Volume(Windows files inside), Windows RE tools, and 481 GB Volume(Ubuntu files inside). When I boot the machine, I get the Install Boot Media ?? comment at attempted start-up. When I was setting up the Ubuntu alongside Windows I could access BIOS(?) with an F2 press at initial flash screen. Now I cannot. I can do nothing but run the Ubuntu Live CD. I don't want to try Fresh install of Ubuntu because there are files on Ubuntu partition because there are files that are too large for me to back-up else where that are very important. I KNOW .... BACK-UP BACK-UP BACK-UP!! It however is too late for that..

Some time ago I replaced an IDE hard drive with Windows 8 installed for an SSD drive onto which I installed Windows 7. I would like to know if I can temporarily swap back to the IDE drive (Windows 8) while I obtain the Windows Product Key (embedded in BIOS apparently) and then replace the SSD drive (Windows 7), or boot from an external docking station and if so how do I do that?I am totally confused about the BIOS. Does a different OS change the BIOS details?

I have recently built a new computer and installed Windows 8. All was running fine (including USB devices such as iPhone, flash drive etc), however since upgrading to Windows 8.1, none of my USB devices are showing up at all. Oddly, the mouse and keyboard still work.
When I go into the BIOS, all my devices (iPhone, Flash drive, keyboard and mouse etc) all show up in there, so I'm guessing it's a driver/Windows 8.1 issue that I'm missing?
I have been to the ASUS website and downloaded all the drivers I can find, but still no luck.
My motherboard is an "Asus Z97 Pro". I have tried contacting Asus support, but they are completely useless!

Every few weeks, I have to get my old graphics card and change the BIOS settings because the CSM mode just resets out of nowhere. The new graphics card isn't compatible with windows 8 so I have to go back and enable the CSM settings to get it to work. Is there a reason why my BIOS keeps resetting the next morning I wake up?
