Q: How to enable AHCI mode for sata drive instead of IDE mode??

I have a motherboard Asus p5k se/epu( intel p35 board). I felt that my sata drive emulated in IDE mode... So i want to fully utilize the sata drive in xp.

Therefore I follow the method provided by other forum's member.

But the problem is that my bios setting only have one option that allowed me to select.. which is IDE mode ONLY!!! Where is the AHCI mode ?

Or any of you have your own standard way to enable AHCI mode? teach me please...?

hi all. i just got an asus a8r32 mvp deluxe crossfire board, and it has tons of options in the bios im not used to seeing. one of them, under storage, allows you to run your sata drives in 'emulated pata mode' or 'AHCI mode.' i have read that AHCI is faster, but what exactly does it do, and how do I get my computer to support it, because everytime I enable it my system reboots and will not load windows. thanks.

Hi, I recently purchased P53s in Windows 10. I've been trying to dual boot with Ubuntu but the computer doesn't recognize the SSD when booting with a flash drive. In bios, I can't find a place for changing the SATA mode to AHCI (no sata configuration). Should I update the bios? Please let me know what to do. Thanks!

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

A:can't boot from cd/dvd sata drive/AHCI mode

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.

So after I changed to SATA AHCI mode in the BIOS, the main boot internal hard drive shows as a removable device in system tray. So how do I fix this issue, and I did follow the instructions in the Microsoft Knowledge Base article 922976, http://support.microsoft.com/kb/922976
to enable the sata driver first before I changed the BIOS setting. However in the Vista on the
same hard drive in the same computer, with the same SATA AHCI fix done to enable the needed
drivers, the internal hard drive does not show in the system tray as removable. So possibly if
I install the Intel Matrix Storage Manager from their site for this ASUS P5QL Pro motherboard
with a Intel P43 express chip set, known as ICH10, then after a re-boot it may no longer show
as removable. This computer is a 2009 store built desktop that has only one 500 GB SATA hard
drive installed. I had it set in the IDE compatible mode, so that I could mult-boot with XP, Vista, 7, and Ubuntu Linux.

A:after change to SATA AHCI mode in BIOS the drive shows removable

That's not an issue at all, and it's perfectly normal. AHCI offers, on some boards, hot swap capabilities. It's nothing to worry about.

I have bought a new SSD which I plan on using as a program drive, though not as OS drive (will reinstall Windows in the next few months). Currently I am running Windows 7 Pro 64bit.

My OS is installed on a Western Digital 2TB drive. It is set to run in IDE Mode currently. My motherboard, an MSI Z87-G43, only has one SATA controller.

I have recently acquired a Crucial M500 240GB SSD. I have it plugged into a SATA 3 slot with a SATA 3 cable. When I booted into the BIOS first, it changed my motherboard to AHCI, so I manually changed it to IDE mode as my OS HDD ran in IDE.

I then booted into Windows, formatted the SSD, and copied some files to it. It appears to be working.

Essentially, I am running on an HDD with my Windows 7 install in IDE mode as well as an SSD running in IDE mode.

I am wondering if it is possible to change from IDE mode to AHCI without reinstalling or corrupting Windows 7 install or any data on either my HDD or SSD?

The tutorial here seems straight forward, though I just wanted to ensure such a process would work in my exact hardware/software configuration:
AHCI : Enable in Windows 7 / Vista

If my hardware/software does not have any issues then I will go ahead and do the registry edits.

Thanks in advance for any help.

I have just completed a new build using my HDD's from my old computer so I an running Win XP Pro SP3 32-bit before installing Win 7 Home Premium 64-bit.

My HDD are configured as IDE in bios and everything works fine. If I reset the HDD mode to AHCI I only get the windows splash screen and the system restarts.

Searching the archives I found the following from crjdriver :

FWIW I have done some tests running native or standard ide and ahci. On an intel p35 chipset board, an amd 770 chipset board, and an intel 945 chipset board. On each one, native ide actually gave better performance in a benchmark. Not by much however it was faster with both a raptor drive AND a seagate 7200.11 drive. If anything should benefit from ahci, it should be the newer seagate however it did not.

Hey everyone. I hope everyone is doing fine. I've literally rebuilt my entire machine but I think I made a mistake before installing Windows 7.

I should have gone over the BIOS with a fine tooth comb, but I did not. The SATA mode is set to IDE instead of AHCI or RAID and now of course, I can't switch it to my knowledge without getting a BSOD. It means I would have to reinstall the OS over again.

I have been reading up online and did a search here, but didn't find the appropriate thead. I have two questions. I read on a forum somewhere, where an Intel user used a program to change this in Windows somehow. Is there some kind of utility that will allow me to switch to AHCI mode without reinstalling Win7 64bit?

Second question, is it worth it to switch over? I see the benefits are this:

AHCI mode brings 3 main advantages:
Supports NCQ (Native Command Queuing) allowing SATA drives to accept more than one command at a time and dynamically reorder the commands for maximum efficiency.
Supports hot plugging of devices
Supports staggered spin ups of multiple hard drives at boot time

My machine seems kind of slow when accessing data and don't know if this is an issue with the SATA drives being in IDE mode. I got some choppiness in some games that's coming from access data (tested) and that seems weird but could definitely come from SATA drives being in IDE mode.

A:Sata Mode AHCI / IDE

That's weird. I thought Windows 7 handled switching to AHCI mode better than that. Guess it has the same problem as XP.

Anyway, quick answers to a couple of your questions:

1) There is nothing magical about AHCI. About all you will gain is the ability to hot-plug drives. That may be worthwhile if you use an external HDD connected by eSATA. Otherwise, I wouldn't worry about it.

From what I've read, NCQ is only of real benefit in an environment where the disk is being accessed constantly, such as server. Normal desktop users probably won't see any measurable benefit.

The staggered spin-up thing probably doesn't matter either. Maybe it would, if you were running a large RAID (like maybe a 6-disk RAID 10) and had a barely-adequate power supply.

2) Yes, there should be a way to install the AHCI drivers so that Windows 7 doesn't bluescreen on startup. I did it with Windows XP, although it wasn't all that straightforward. I didn't have to reinstall Windows XP, and you shouldn't have to reinstall Windows 7 either.


Just for curiosity, I tried switching my disk controller to IDE mode. Windows 7 booted, but then made me reboot immediately, presumably because it had to install the IDE-mode drivers for the disk controller. On next startup, I re-ran the Windows Experience Index test. My disk score remained exactly the same (5.9) as when I had the disk controller in AHCI mode.

I then restarted, got into the BIOS menu & switched the disk controller back to AHC... Read more

I have a company laptop (HP 8530w) with Checkpoint Pointsec HDD encryption and 32bit Vista.
I want to use win7 booted from an external eSATA drive. For that to work first of all I had to remove the internal HDD, because win7 install has already ****ed my system up one time (probably the MBR because the encryption never came up after I installed win7 on the external drive). Secondly I had to set SATA mode to IDE because in AHCI mode it can't be booted on this laptop. (RAID would also work but I didn't want to complicate things).
My question is if I try to boot from the internal drive would it **** Win Vista up or even the encryption stuff? I mean without resetting SATA mode to AHCI (so that i don't have to change it every time I want to boot from the extrnal drive). And that's not even the biggest issue: for now I think I will remove the internal drive every time I want to boot another OS, I don't want to go to IT support all the time.

Basically what i wanted to achieve is to get the laptop to boot from the external drive whenever it is plugged in at home, but boot the company OS Vista at work. It seems it is not that easy.
Do you think it can be done?

I have an XP + Linux dual boot setup. I booted XP for the first time in months, and it immediately went back to the BIOS boot (no BSOD, only the automatic reboot). Safe mode did the same thing. After experimenting with BIOS setups, I discovered that the problem was apparently triggered by my changing the SATA controller setup from IDE to AHCI mode. Linux is OK with this, but XP apparently not.

Can someone verify this? Do I need another driver for XP? I doubt if the performance gain from AHCI is noticeable (true?) so perhaps it is just as good to keep the IDE mode for both OS's.

A:XP does not boot if SATA in AHCI mode?

my 2 cents: keep IDE mode.

however, the problem can solved by forcibly installing the xp SATA driver while in IDE mode (you must install hardware that is currently not connected). then restart in AHCI mode and windows XP should work.

I installed XP in dual boot mode with Vista pre-installed on a Toshiba Satellite L350-20J notebook.

Since I couldn't find the appropriate files for the F6 process in the Matrix Storage Manager (in the L350 Toshiba driver section for XP, you get an EXE file) to use at xp install time, in the BIOS I switched the SATA AHCI parameter to "compatibility". The XP installation went fine.

Once XP was installed, when I tried to run the Matrix Storage Manager driver, I got the message "This computer does not meet minimum requirements for installing the software". On the other hand, the chipset utility was installed without a hitch.

When I switched back the "compatibilty" parameter to AHCI in the BIOS, the system would not boot properly. It would direct me to multiple choice screen for Safe mode, etc.

Furthermore, EasyBCD gets stuck when I try to define Vista in the Add/Remove entries section.

How can I get into SATA mode at this stage?

Hi, back with another issue on a different computer.

I'm installing Seven on a WinXP machine and completed the install, but forgot to change the SATA setting in the bios from "compatibility mode" to AHCI. Now when I change it, windows gives me bluescreen on boot.

I'm dumbfounded that Windows Seven startup repair can't fix a problem this simple, but it completely failed, wasn't even able to find a problem.

I was thinking it might be easier to just reformat and begin the install over again, or startup in safemode and install the intel SATA drivers... assuming it will let me boot into safemode with AHCI enabled.

Is there another alternative here?


ps. On the other computer (different thread), I'm going to wait till I have several hours of uninterrupted time, in case I need to begin over installing all the windows versions one at a time. I'll reply with any success/failure on that thread later in the week.

A:Changing SATA from Compatibility mode to AHCI

Not to worry - Windows 7 actually already has a generic AHCI driver; it just needs to be enabled before you change the mode in your BIOS.

Microsoft provides a step-by-step guide for doing so, which involves nothing more than setting a single registry value.

I recently got new Intel SSD series 330 60gb in addition to my standard 1tb Samsung HDD. So I set RAID mode from IDE to AHCI in BIOS (mobo MSI X85 pro-e). Now some of SATA ports (port 3 and 5) don't recognize my HDD or CD/DVD being connected but I still can use them in windows while other ports display them normally in BIOS. Also when I switch back to IDE mode, ports 3 and 5 display hardware in BIOS.

I have an Asus M4N78 PRO.

There are 6 Sata connectors but 2 support AHCI and RAID mode only. (4 red and 2 black)

I have 3 harddrives and 1 DVD connected in the 4 red ports.

Maybe I'm going to buy a SSD to speed up my PC Is it possible to use one of the black sata ports if I enable AHCI. (I don't want RAID, just want to use it like the others SATA ports).

Then should I put my DVD or a harddrive in the black port?

A:SATA that support AHCI and RAID mode only

If you enable AHCI, I suppose that SATA ports 5 and 6 will behave like the other four SATA ports. I see no indication in the M4N78 PRO manual that ports 5 and 6 are on a third-party controller.

On my own Asus motherboard, I'm using AHCI mode. An SSD, a HD, and two optical drives (all SATA) work without problems.

I don't know how easy it is to switch to AHCI mode without re-installing windows with your nVidia chipset. It's not difficult with Microsoft drivers:

I had a computer with windows 8.1 installed but the HDD died. So I bought a new one and installed windows 8.1 with SATA mode IDE. Everything was fine untill I shut it down. When I tired to open it said that there were no bootable device. I tried everything
and finally when I changed SATA mode to AHCI it saw the HDD but could not start Windows, so I changed it back to IDE and it started Widows as if nothing had happened.
Whenever I shut down the computer and try to start it, the same thing happens, and I do all these steps again.

I also tried to install windows 8.1 on AHCI mode, but the same thing happened again. But this time I had to switch to IDE and then AHCI again.

Also, when I pick restart option, not shut down, there is no problem. It restarts just fine.

Do you have any idea why this is happening or how can I fix this?

Hi everyone I've got a Latitude D820 and I really like it. I'm really interested in getting an SSD to put in this system but I have my doubts. I have been told that SSDs only really like being in ACHI mode but the D820 doesn't have this option in the BIOS. I've also been told that SSDs running in IDE compatibility mode will cause bluescreens and have slow performance.
I did some digging around and discovered that Dell have hidden this option from BIOS setup for the sake of saving time, answering costumer support calls regarding SATA operation and drivers.
So my question is, will Dell be able to release a new BIOS revision with this feature enabled? The D820 is still a capable and i would hate to see it crippled in this way.

A strange problem, nothing critical, but I found it annoying that my optical sata drives will not boot from a bootable disk when in AHCI mode in Bios. If I switch the drive mode to native IDE then I can boot just fine from either of the Opitcal Sata drives.

I have done some searching and found this has been a problem out for some builds/MB in the past but you would think with a new MB and Sata controller and such this would no longer be a problem.

If you look at my specs you will see the Gigabyte MB. The documentation is fuzzy on the sata ports. There is a setting to put SATA port 4/5 into some kind of IDE support mode. I currently have the slots 0 - 3, used for all the drives. 0 & 1 for HDD, and 2 & 3 for the optical drives, wondering if I use the 4/5 slots for the SATA and set the bios to the 4/5 ide support if this might solve my little problem.

Has anyone else out there run into a similar problem?

A:AHCI mode no boot from sata optical drives

Optical drives to my knowledge don't benefit from AHCI.
You have 2 controllers, Intel and Gigabyte.

1. Install SATA hard drives on the Intel controller and set it to AHCI.
2. Install Optical drives to the Gigabyte controller and set it to IDE.

Even if you did set all controllers to AHCI, double check the boot option and make sure that the optical drives are set as the first boot device.

Ideally, the hard drives take advantage of AHCI, so it doesn't matter whether the optical drive is set to AHCI or IDE.

Hi. My desktop (h8-1080t) is about 5 years old, and is configured with two 1TB, factory-installed HDDs, along with a custom-installed 250GB SSD where my OS (windows 10) now resides. Out of the box, the two HDDs were configured in raid 0. When I moved my OS over to the SSD about a year ago, I changed the sata controller mode in the BIOS from "RAID" to "AHCI." Now, since I'm about to sell my computer, I changed the mode back to "RAID" (my intention was to configure the hard drives into RAID 1, so as to increase reliability for whomever buys the computer; I now realize that HP's bios doesn't seem to support anything besides RAID 0). Anyway, after making this change, my computer will no longer boot. I get past post and the screen is black with a blinking white cursor, as if the operating system isn't there. No blue screen. No text. Nothing. After doing some reading, it seems that I needed to do a clean OS install if I wanted to change the controller mode. After trying to revert back to AHCI mode and even IDE mode, the issue persists.

Or can I make the changes first in Vista and 7 to enable the needed sata driver, and boot to the BIOS to switch the mode, then boot to either the Ultimate boot CD for Windows or my real XP CD disk to attempt to then install the XP sata AHCI driver ? I just want to avoid a full re-install of XP. Or I can clone an image of my XP drive partition to then put onto a PATA IDE second new hard drive ?

I am a user of the vistax64 forums and found thread on the 7 forums related to a problem I have. I use vista but I don't think my problem is OS independent. Anyway, I stumbled upon this thread:
Sata Mode AHCI / IDE

A user, Unifex, posted this "Well, that's the thing for Dell Inspiron - there is no separate setting in the BIOS for AHCI. Only IDE and RAID. But, RAID actually corresponds to AHCI, so by choosing RAID I actually get the AHCI BIOS screen and so on"

That is exactly what I want to know how to do. How do you get the AHCI BIOS screen after selecting RAID in the Inspirion 530s BIOS? I am aware this is a very hardware specific question. I hope this is appropriate for these forums. Unifex, if you happen to be reading this post, I would greatly appreciate your input considering your familiarity of this BIOS.

A:Selecting AHCI SATA mode: Dell Inspirion 530s


I believe the RAID option is for the AHCI. There inst a separate BIOS Screen for this option although it may show a few more settings on the BIOS relating to the RAID. If you are going to setup your OS so that it uses AHCI then you will have to download the drivers first or your system wont boot.

Hi: It is best if you can, but you cannot until you install the SATA ACHI driver. If you have an Intel processor, I can help you do that.  If you have an AMD processor, I can't because I don't know how. If you have a notebook with an Intel processor, please post your full notebook model. It isn't really a big deal if you can't change the setting back. You'll hardly notice any difference. It is just that ACHI mode allows the hard drive to perform more efficiently for lack of a better word. See this article for more info. http://www.differencebetween.net/technology/difference-between-ahci-and-ide/ Paul

I Installed windows on a ssd drive running in ahci mode. I then switched the sata setting in the bios from ahci to raid in order to add 2 other hdds as a raid 0. Now the pc won't boot anymore getting no boot device error. I know about the registry fix to get an IDE sata drive to boot in ahci mode, is there a similar solution to change a dire from ahci to raid?
Note the mb only has 1 controller so I can't have the boot drive in ahci mode with the other 2 in raid mode.
Thanks in advance.

A:Can I switch my boot disk from ahci mode to raid mode?

Hello Danag, and welcome to Sevenforums. What kind of computer do you have, or did you custom build it? Go to it's manufacturer's website and install the Raid drivers.

EDIT: set it to RAID after the Raid drivers are installed, it will be fine. Let me know how it goes

Hi. I have a PC with an Asus M4A79T Deluxe motherboard. The board has 5 SATA connections but I think ports 4&5 share a double connector. Originally I had this machine set up with a pair of 150GB drives in Raid 1 for the OS (ports 1&2), a pair of 500GB drives in Raid 1 for Data (ports 3&4) and then the DVD drive on port 5.
Recently I decided that Raid 1 was not the best solution for me as there are other good ways to backup data. I bought an SSD with the idea that I would use this for my OS and separate out my 500GB drives to double my data storage space. I connected the SSD to SATA port 1 and installed Windows 7 on it. I can now boot to this drive or my old drive on port 2. But the BIOS is still set up for RAID so at boot up it is reporting that the array with 1 disk removed is critical. I would like to get rid of this and also split the data disks so they are no longer in RAID.
Having done a little research I believe that I need to change the BIOS to AHCI mode instead of RAID. However, when I do this the machine detects the 4 hard disks that are connected on ports 1-4 but does not see the DVD drive on Port 5. The machine also fails to boot. I think I may be able to get it to boot in AHCI mode if I could run Startup Repair. But I cannot try this without the DVD Drive working. I would really appreciate if somebody could help me sort out this configuration so that I can remove RAID and get all my drives working.

A:Pls help to get DVD Drive to work in AHCI mode

I had a bit of a break through with this. I was able to get the system to boot in AHCI mode by changing the value as describe here:
The AHCI drivers were then automatically installed to each drive.
The only problem now I believe is that I think the DVD drive is still not seen at boot but it is seen within windows. This just means that I cannot boot from the optical drive which should not be a problem most of the time. I think I can remedy this by plugging the DVD Drive into a different SATA port. But any feedback would still be appreciated.

Hi, I just want to know what the best mode is, IDE or AHCI, my board has defaulted to IDE so that's what I'm currently using.


A:Hard drive mode: IDE or AHCI?

If it's an SSD then you should change it to AHCI and reinstall Windows. If all of your drives are normal HDDs then it won't make any difference.

I have successfully installed Windows 8 Pro x64 on an ASUS P8Z77-V Deluxe board on a SSD under UEFI/secure boot mode. Used the following settings:
Fastboot = enabled
CSM = enabled
Secureboot = Windows UEFI

Everything works fine. Qcode = AO, performance is excellent etc. System information shows:
Secure boot state = ON
SSD partitioned to GPT

I now want to create a RAID1 volume on which to store my data. I understand that ideally one has to set SATA mode to RAID before installing windows in order to make the creation of RAID volumes possible.

However, is it possible to convert my present AHCI system to a RAID system without re-installing windows? I heard that some registry settings will do the trick.

A possible alternative kind of RAID1?
I have been checking the user manual of this board and on page 3.39 there is a description of Drive Expert Mode. It can be set to Normal Mode, Super Speed or EZ Backup, where EZ Backup means: "Allows you to use the EZ Backup function that copies and maintains an identical image of data from the SATA6G_E1 drive to the SATA6G_E2 drive".

How different is this from the RAID function set up with Ctr-I? Is it better or worse in terms of fault tolerance and performance?

Many thanks for any advice.

A:Convert AHCI mode to RAID mode without re-installing

On that board, to get full Windows 8 Secure Boot, you have to Disable the CSM. I know it shows "On", but it will show that until you select Other OS in the Secure Boot section. If you have a Video card installed, such as a GTX XXX, it may not yet be Secure Boot capable and will cause the system to abort the boot and put you back in the bios, when the full Secure Boot is in place.

Have you looked into using Storage Spaces as opposed to RAID? There have been some comments about it is not as stable as RAID, but I have no personal info. Maybe some others will have some information.

If you want to change your system to RAID, it can be dangerous, so backup everything you can, and remember, if it doesn't work, set it back to AHCI.

This is not recommend for Windows 7, just in case anyone wanted to try.

When in Windows 8, open msconfig.exe and set the Safe Boot check box on the Boot tab.

Restart your system and use the Del key (for ASUS P8Z77) to get into the bios. Go to advanced settings and change the AHCI to RAID. When you select save, your system will reboot and this time, let it boot into Safe Mode.

While in Safe Mode the drivers will be changed. You can check Device Manager if you like and you will see an entry in Storage Controllers for the Intel Deskto/Workstation... . But you need to open msconfig.exe again and uncheck the Safe Boot box. Then close it and reboot back into normal Windows.

If at any time the system tries to do a repair operation,... Read more

My LG optical drive, model GH22NS40, popularly called "Super Multi DVD Rewriter", running on Windows 7 64 bit, will not burn a DVD-R if the SATA controller is in AHCI mode. All other optical drive functions work OK -- reads and burns CD-R, reads DVD. Attempting to burn DVD using Windows 7 Explorer gives this error:

Dialog name: Burn to Disc
Insert a disc
"There is no disc in the CD or DVD burner.
Please insert a writable disc into drive d:."

Switching to IDE mode in motherboard BIOS solves the problem. However this causes all SATA devices to work in IDE mode. I have several SATA hard drives, so would prefer running them in AHCI mode.

I have a Toshiba NB300 netbook, running Windows 8 Pro 32 bit, very happy with it!
I have a Corsair Force 3 112GB SSD drive installed, and everything seems to be running very nicely!

Reading up on SSD drives I see that for best performance I should be running the SSD in AHCI mode.
So I went to the Setup menu on start up and changed from Compatibility mode to AHCI.
I've actually tried this a few times, always with the same result, failure!

When the system attempts to boot I get a message saying a problem was encountered, and that
the sytem is trying to gather information.

The only solution is to go back into setup and reset to Compatibility mode.

The BIOS is up to date, and I just can't think of any way to resolve the issue.
I really would like to get the best performance I can on this net book.
I have a screen grab of the SSD drive details from Speccy, but I can't see a way of attaching it?

If any one can advise me on how to get AHCI mode up and going I would really appreciate it!



A:NB300 unable to set to AHCI mode for SSD drive

Unfortunately on this forum we don?t have reports about SSD usage on NBs. I have NB520 and I would like to use SSD to but until now I didn?t find the right one.

As far as I know by default BIOS is set to AHCI mode. Which OS have you installed? Original one that you got with your notebook or your own version? Have you installed Intel?s storage manager from Toshiba download page?

Yesterday my Wife's laptop stopped booting for her so I started to troubleshoot it.

What I've discovered is:

- If the BIOS setting for the hard drive controller is AHCI it will not recognize the drive. (This was the default setting in the BIOS)

- If changed to IDE mode it recognizes the drive but come up with an "No operating system detected" message.

- If the hard drive is installed in a second lap top it works fine.

- If another hard drive is installed it works fine in AHCI mode.

Only the combination of the original hard drive and the original lap top wont work.

Am I missing something?


A:AHCI mode stopped reconizing Hard Drive

You may want to see if any bios updates are available for it.
IDE mode will never see the AHCI data it can be reformatted in ide mode and then have windows installed on it.

Here is a thought though.
completely power down the laptop remove the battery and everything.
Let it sit for an hour or so like that.
Plug everything back in and give it another try in ahci mode.
This only has a small chance of working but it's worth trying.

I recently buy a Dell XPS 8900 desktop computer (i7-6700, 3.40G). Flash BIOS has been updated the the latest version (Aug. 2, 2017) now.
I need it dual boot of Windows 10 and Ubuntu 16.4. As Ubuntu 16.4 installation requires the hard drive in AHCI mode, it is set in BIOS from the default RAID to AHCI. Unfortunately Windows 10 cannot boot correctly with AHCI mode.
The Ubuntu 16.4 installation is failed in all the trials at the moment. 
What is wrong in this hard drive mode change?

A:XPS 8900 desktop computer cannot boot with AHCI hard drive mode

Sorry, I did not give more detail on the boot failure previously. When boot in AHCI hard drive, the DELL logo appears. It says diagonsing something. Then, a blue screen comes. It says Automatic Repair, but it can succeed. Only I change AHCI back to RAID mode, Windows 10 can boot correctly.
Can you help me? Thanks,
