Windows 7 64bit PC With 3 X 3TB Hard Drives No Longer Boots In AHCI Mode?
Jul 5, 2011
I successfully installed Windows 7 64bit in AHCI mode on a PC with 3 new 3TB Western Digital WD30EZRX Caviar Green hard drives.Then I installed "Intel Matrix Storage Manager Driver [v8.9.0.1023]" & as soon as Windows restarted after installing it, Windows would not boot, & will now only boot in IDE mode.In IDE mode I have to do a system restore to the point before installation of "Intel Matrix Storage Manager Driver" to be able to boot again in AHCI mode.

i'm working with a new pc build that uses a 60 gb ssd for its boot drive, and which is also reusing some "old" sata hdds for storage.
at the time i installed windows 7 ult 64, i had only a new ssd plugged in, and the bios was set to ahci mode. the installation went fine and i was able to boot into windows afterwards without issue.
then, i connected a wd caviar black sata hdd to use as storage, with the ssd being the boot drive. with both of them connected, windows will not get past the starting windows screen.
i made this video of the program before i understood that it was a drive controller issue: startup problem - Internet in it, you can see that windows boots fine in ahci mode with just the ssd plugged in, but that when the backup sata drive is also connected it doesn't get past the starting windows screen.
for the record, this caviar black hdd was my previous boot os, and it also has a windows 7 install on it (which i've renamed the base folder of), but it is not booting from that hdd. also, i have tried the same thing with other "old" sata hdds that do not have any previous windows install on them, and the result is the same thing which is shown in the video.

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.

I created a system image on an AHCI system, then I replaced the hard drives & re-imaged the system. Now Windows won't boot in AHCI mode, it has to be it IDE mode. Why is it not booting in AHCI mode?

After trying to scan my computer with tdskiller (I believe its called) to remove some viruses, I was asked to reboot. When I did, my backround desktop picture turned black, files seemed to be missing from my desktop and a window poped up scanning and telling me how many errors I had. Shortly after I got about 20 error pop up messages. I rebooted my computer and more files were missing to the point all I had was recycle bin, and two other programs.
Now the computer runs only in safe mode, No matter what I do (pressing f8 - start in normal mode) nothing works. I cant get internet access, and worst of all, I cant even system restore or even recover it back to to the malfunctioners option due to errors. I am stuck and do not know what else to try.
Ive tried the repair option in dos aswell and it just keeps me in the "Loading window files" screen, as I left it there for nearly four hours im guessing that was not going to work.

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.

I use a lot of different usb hard drives in my shop. I have two basic enclosures, a generic one that uses pata drives on a usb 2.0 cable and an Apricon USB SATA 2.0 adapter.Suddenly when I plug in a new drive device manager does see the drive and installs it in device manager. I can see the drive in Disk Management but it has no drive letter assigned, and therefore doesn't show up in Computer. I can easily just assign a letter in Disk Management and the drive immediately becomes usable. However, I would like to get Windows 7 to resume automatically assigning a drive letter.
I have tried a program called USB DriveCleanup. What it appears to have done is remove all installations of prior USB drives and when I plug in a drive that has been in the machine previously it then goes thru the install again. Yet still no drive letter. I think the program is doing what would manually be done by going into safe mode and cleaning out all the entries that build up there that don't appear in normal mode, then removes them. Basically it seems like a shortcut to manually doing it.
I also tried a registry fix that essentially asked me to delete the upper and lower filters. This seems similiar to fix for CD/DVD drives that no longer appear in Computer. This fix also didn't work.I tried removing and reinstalling the chipset drivers. Still no go.Running Windows 7 Pro SP1, H55 chipset.

So just a few minutes ago my desktop was running fine and all. I was opening and reading documents off my flash drive when all of a sudden it turned off and proceeded to restart. Upon passing the POST screen, it comes to an error page that says boot device not found. Just FYI I have a WD 250GB boot drive and two additional Samsung 1TB drives set up in RAID 1 NTFS. So I look in BIOS for my boot drive and find it there and it says its working. However, when I try to set the WD boot drive as the first boot device, it does not show it as an option at all. Only my raid drive shows up along with removable drive, and cd drive.I need some ideas as to what could have caused this. The WD drive is a few years old, but I don't think the drive would have just died like that; there were no previous cues for the hard drive starting to fail. It still shows up in BIOS and powers up.I wanna hope that the MBR was somehow corrupted, which should be an easy repair I think if I can get my hands on the ISO file. Also, it's Windows 7 Ultimate 64 bit

I have an HP Quad Core computer that came with two hard drives.I installed Windows 7 32 bit a year ago. The disk also came with a 64 bit version but the upgrade required a clean install.If I decide to install the 64 bit version, do I lose everything on both drives?

anyways, my main drive is a RAID 0 with Vista x64, but I have a second HD that is a SATA 250GB, which I installed Windows 7 on. The only way I could get install to work was to switch my BIOS to IDE mode rather than RAID. I would of course though, like to be able to access my Vista drive from Windows 7 (and more importantly, not have to switch between IDE/RAID mode at all in the BIOS, it's a pain).
Now, the one odd this about this all is that the drivers I have for Vista (x86/x64 drivers) for this mobo's RAID controller WORK when loaded on installation to identify and install to the drive, but seem to not load or not work in any way once the first reboot on install occurs. Maybe this is because I installed from within Vista x64, though.
(Incedentally, my motherboard is an M3A Asus, using ATI's SB600 for a RAID controller)
I've tried loading the drivers from within Windows 7 while in IDE mode, but the install program won't let me. At first it didn't allow because of version restrictions, but then I altered the ini file to get around that, but it encounters some sort of error when installing and quits.
Any help that can be offered, would be grateful. I realise it's a beta and not a real release, so I can get past the BSOD from my odd setup, and I really am enjoying playing around with it so far. Very very impressed.
Edit: Just in case anyone thinks of suggesting me to right-click the inf file and install that way, already tried, won't allow for it.

After restoring an image made with Clonezilla that used to work, Windows 7 is unable to start. When prompted, I used the DVD, but it still fails with "Startup Repair could not detect a problem".When rebooting, it says "Windows Error Recovery: Launch Startup Repair (recommended) and Start Windows Normally": Launch Startup Repair fails with "Windows Boot Manager: 0xc000000e The Boot selection failed because a required device is inaccessible".FWIW, to investigate, I deleted both partitions (#1 to hold the OS, #2 to hold images) and re-created them with enough space to hold (#1 was made a bit bigger because I didn't know how to specify infos in cfdisk accurately), and Clonezilla happily restored the image.

Windows 7 x64 does not boot into Safe Mode or Safe Mode with command prompt. Normal mode boots perfectly. Are there any suggestions on how to resolve this? I've tried startup repair and attempted fix boot, etc. No affect. The unit is free of infection. I also tried using SFC, but it said everything was fine.

I did have the following setup, on a single drive, two partitions:
345GB: Windows XP (installed first)
120GB: Windows 7
I've made a slight mistake – I've deleted the partition which hosted the MBR for my dual boot setup.
Basically, I have a single hard drive split into two partitions. I thought that I was thoroughly satisfied with Windows 7, so I decided to delete the partition which XP was sitting on. Little did I realise/remember at the time, but the XP partition held all the boot information, thus rendering my newly formed single partition unbootable. I booted GParted to ensure that my partition was intact, and it showed the following:
/dev/sda1 Extended 465GB LBA
/dev/sda5 NTFS 465GB Boot
(I manually flagged /dev/sda5 as 'boot')
This all appeared normal to me, so I put my Windows 7 disc in and attempted the various repair options. In my experience (with XP), FIXMBR from the command prompt usually fixes the issue, in this situation it hasn't. I've also tried 'BootRec.exe /fixmbr' & 'BootRec.exe /fixboot'. None of which seem to work.
My last attempt at fixing this was using the 'Startup repair' option on the Windows 7 disc. This hasn't worked either.
Can someone perhaps kindly offer me a solution? I'd rather not reinstall Windows.

I had a stock machine running windows 7. I built a computer for myself and I hardly use cds so when I needed to install windows 7 on the new computer I simply removed my cd drive from my old computer and put it in the new one. I assumed that since the os is installed to the hd that the computer would still run but it does not . I already installed windows 7 on the new computer but when I went to boot my old pc up it says no operating system. Do I just need to buy a new cd drive? Or do I need to buy another copy of windows?

I would like the good and bad about running your SATA drives in IDE and AHCI modes.
I have 3 drives. 1 SSD and 2 normal hard drives.
Does it even make a difference? I have an Esata bracket that I want to run in AHCI mode but how about the normal system and data drives? What is the best way to set up drives?

I'm coming from win XP and I've got 3 SATA drives currently operating in IDE mode. I am just about to move to Windows 7 Pro and I was considering setting the motherboard to recognize the drives as AHCI. I am going to reformat one drive completely for the OS drive.
My questions are:
1. Will this negatively affect my other two storage drives because they had previously been running in IDE mode?
2. Is there a way to determine whether or not my drives support AHCI at all? (They're all SATA drives bought in the last 4 years.)
3. I intend to run XP mode, will AHCI mode pose any problems for this?

First thing, my build:
Board: Gigabyte GA-P55A-UD4
CPU: Core i7 870 @ 2,93 Ghz
Graphic: Sapphire AMD Radeon 8670 Mushkin 2x2Gb Red Culvert Kit @ 1600Mhz CAS 6-7-7-18
Seagate 320 GB SATA II HDD + WD Caviar Black 1TB SATA III HDD
Running: Windows 7 Ultimate
Trying to install: Windows 7 Ultimate
PSU: LC Power Arkangel 850W
I have Windows 7 Ultimate installed on my 320 Gb HDD and everything is running ok. I just bought a WD Caviar Black 1TB SATA III disk and I want to install Windows 7 there, since the disk is faster. Here's what happens. When I connect the disk (it is connected GSATA 3 connectors), the disk will be recognized in bios and in Windows, but wont show under My Computer. I figured it must be some software bug so I formatted the disk in diskpart (clean format) and installed Windows 7 on it. At that time the GSATA 3 interface was set to IDE mode. It ran fine but after installing a big batch of Windows updates, the system hung at windows startup screen. After restoring the system to a previous state (i.e. before the updates), the system booted up normally.
I didn't know what was wrong so I formatted again, and this time I set the GSATA 3 to AHCI mode, since I realized this is a better option. When installing in AHCI mode, the computer expands the windows files but when the system is restarted, I get a BSOD (code Stop 0x000000B4 video driver failed to initialize) at Setup is updating registry settings. I really want to use the AHCI mode, but I cant get the system to work in IDE either so its really a bugger. I have no idea what could be causing this as the system works fine when using the other disk. Can the BSOD be caused by the HDD? Anyway, I really want to start using the disk. I have tried installing Windows 7 from a dvd as well as from a USB key.

I changed the appropriate setting in the registry. (msachi > start: 0) Then I changed the setting in my motherboard and Windows froze upon starting up, and my system rebooted.
The thing is, I changed it to AHCI before. It worked fine! I then switched back to IDE while trying to fix a problem with eSATA detection (turned out to be a faulty cord), Now I can't switch back! Sigh. I really would like my eSATA to be plug and play.

I just upgraded my cpu,mobo,ram and HDD recently and I am having some issues. I have the Phenom ll 3.2ghz 1090T amd cpu with the ASRock 970 Extreme 3 mobo with 2x4gb Corsair Vengeance ram. My problem is that when I try to use my ram, my pc freezes on the Starting windows screen while the bubbles are coming together to make the microsoft logo. I am using my old ram that is a 2gb 1333 ram. I have another stick of the same ram but I am unable to use that as well. My OS has all its updates and I am completely stuck right now and a lil frustrated. I have consulted many people and nothing has worked.

My PC only boots in safe mode. It works fine in safe mode. Otherwise , it stops at starting windows and does nothing else. I've backed up all data in safe mode. Now I want to delete everything and install a new version of windows 7. But when I try to install it (from usb) it freezes at starting windows also (it loads from usb). How can I delete my hard drive? (I don't have the thing to connect it to another computer)

New i5-8570k with Z77X-D3H build. SSD's & HD's. 1 backup HD is in a caddy (simple SATA connection, its not a raid device) with on/off switch. BIOS is AHCI by default. Installed Win7 Pro x64 then after chipset drivers with mobo DVD. IRST is installed but notes say it should be installed during o/s install. How to confirm AHCI is on? The drives aren't listed in safely remove/eject hardware icon in systray. HD Caddy is useless because hot swap isn't working or on.
Does the new Z77 chipset require the drivers to be installed during O/S install? I tried that with files on USB flash drive but Win7 prevented it because the drivers were unsigned. These are Intel's latest drivers for the Series 7 chipsets. I've tried to confirm whether i have AHCI on or not, 'AS SSD benchmark' detects 'iaStor'. I guess if the chipset drivers must be installed before o/s install then the question becomes "How to install Intel drivers that aren't signed during O/S install". There is no 'ignore & continue' option.

I tried to install with my graphics card ATI ASUS EAH4350, but I couldn't install win 7. It stopped when "starting for first use" message. But I found solution to install Windows 7 in vga mode and it worked. Then again I put my graphics card and started win 7. It automatically installed vga driver and asked me to restart before I install ati catalyst driver from cd. After restarting when black screen comes before "win 7 welcome screen" it freezes with mouse pointer. It only starts in vga mode or safe mode. By the way I have win xp as well in c drive nad installed win 7 in h drive.

I recently upgraded to an SSD. I moved windows 7 over to the new SSD and re-aligned the partition properly The drive setup is as follows:
2x 500GB WD Black drives in RAID 0
1x 120GB ADATA S510 SSD
In BIOS, RAID mode is enabled. You cannot enable RAID for one pair of drives and AHCI separately. I was assuming disks that are not part of the logical RAID volumes would be set to AHCI automatically. I have enabled NCQ in AMD RaidExpert for the SSD.WEI is 5.9 for the primary disk. The primary disk is the SSD.Other strange behanivour is that the RAID array and the SSD both appear as SCSI devices in device manager, and Windows won't accept the ahci drivers from ECS.

i have an ASUS M5A88-M motherboard, and a Western Digital WD2503ABYX HDD. i am trying to make that drive work in AHCI mode, but when I try, the disk won't boot. i think the HDD is AHCI compatble, tho not certain. i went into the registry to set a value=o for the relevant AHCI parameter, but no luck. if i need a full re-installation of Windows 7 64-bit, does it prompt me along the way to set the mode to IDE or AHCI?.
