Lose HDDs (boot Hangs At DVD Sniffer Boot) After Switching To AHCI?

Apr 10, 2011

Win 7 x64 Home Premium w/Gigabyte GA-EP45-UD3P, v.1.1 (P45), works great in IDE mode. (N.B.: eSATA port is just regular SATA port w/cable as provided by Gigabyte.) Trying to install external eSATA HDD. First I enabled AHCI drivers via registry. Then I turned on AHCI in BIOS. When I save BIOS and reboot, boot hangs when DVD writer performs sniffer boot, i.e., HDDs aren't found.

Convert Dual Boot To Single Boot, 2 HDds

Aug 27, 2009

I setup an XP/Windows 7 dual boot on two drives. Currently C: Windows 7, D:XP

Love Windows 7 and now I'm ready to convert to single boot Windows 7.

I'm not real savy re. bcdedit so will need very detailed instructions

I did find the command line in Windows 7 by going through accessories but I'm scared to go further without help.

Eventually I want to clean up the D:xp and use it for storage etc.

I'm guessing this procedure may have already be written up but I can't seem to find it.

SB600 ATI RAID AHCI Drivers? (BSOD On Boot If In RAID/AHCI Mode.)

Jan 6, 2009

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.

Dual Boot From 2 Different HDDs?

Dec 28, 2012

I'm new around here so, if you've seen this before, please bear with me.I have a computer with 3 hard disks in it as follows.Patriot Pyro 120 GB on Windows 7 Ultimate x64 (installed first).WD Velociraptor 450 GB on Windows 8 Pro x64 (installed second).Samsung something 2 TB storage (forget about this one).The 2 operating systems are completely independent and functioning properly; obviously, the SSD (Pyro) is set to boot first in the bios and, at start-up, there's no boot manager asking me which OS I intend to use. Basically, every time I want to logon on my Velociraptor with Windows 8 I have to press F8 at start-up and choose from the given list of bootable HDDs.Now, I've tried EasyBCD without luck and I've read somewhere that, apparently, the Windows 7 boot manager can't boot a Windows 8 partition so, my question is, is there a way to add my Windows 8 Velociraptor to the boot manager of the first booting HDD, i.e the SSD with Windows 7?

Will Not Boot From SSD When Attach Additional HDDs?

Feb 14, 2012

I am upgrading my HTPC that i put together a few years back to have a SSD as a boot drive to increase space, quiet background running and speed up booting, etc.Everything was running fine before trying to exchange the raptor for the m4. I had a big issue getting Windows installed on m4 but finally did a clean install when no harddrive was connected except the SSD to the original SATA port of the boot drive. Once I had windows installed, and i was able to boot up with only the SSD attached to the boot SATA port, I attached the 3 storage drives to their original SATA ports and got an error when booting... it paused in mid boot, then started searching for a boot disk in the DVD drive. I looked at the BIOS and the SSD is listed as 1st (port0) on hard drive boot order and hard drive is 1st boot priority. I unplugged all 3 storage drives and it booted up without an issue

Boot And System Partitions On Different HDDs

Nov 17, 2012


I've just discovered (after a panicked hour trying to work out what was going wrong) that my boot and system partitions for windows 7 are on different hard drives. The boot partition is on my 120GB SSD and the system partition is on my 320GB WD HDD.

This means that I have to have both hard drives plugged in for my system to boot. Obviously this isn't the best set up as if one of the hard drives fails then I'm screwed! Is there any way to fix this without having to re-install windows?

Vista / 7 Dual Boot Separate HDDs

Nov 3, 2009

I've done some searching for this and found some similar issues but nothing fits exactly what I'm trying to do. I have been running Vista Ult. 64 bit for a little over a year and have loved it. It solved all the problems I had with XP Pro 32 bit on my hardware. I bought 7 Pro 64 bit through www.theultimatesteal.com since I'm taking some night classes. I forgot I couldn't upgrade from Ult.

to Pro so I had to do a clean install, which I did, on a separate drive. I have five drives in my system, C, D, and E are all 1TB while F and G are 1.5TB. C is where Vista is installed and G is where 7 is located. I'll be going back and forth between the OS's until I get everything the way I want it.

At that point I want to remove Vista and have 7 be the only OS. But I do not want to migrate the install onto the 1TB C: drive, I want to keep it on the 1.5TB drive but have it recognized as the C: drive. The install was done from within Vista from the download since my physical media has not yet arrived. So even when I boot into 7, it is seen as being installed on the G: drive; it did not make itself the C: drive.

So I'll need to get rid of Vista, get 7 to see itself as being the C: drive, get rid of the boot menu, and swap the drives and cables around to put my 7 install at the head of the HDD pack. I've already done a full system backup of my Vista install with Acronis TIH 2010. How do I need to go about this? On another note; why did MS only offer home and pro through ultimate steal? They offered Vista Ultimate. I mean, it is called ULTIMATE steal, not Pro steal afterall, and it would have made the upgrade process that much easier.

Dual Boot Windows 7 & XP From Separate HDDs?

Aug 4, 2012

I want to combine my 2 desktops into one, since I never use both together and the older one is very dated by now (think Time/tiny computers old). My current machine is an Asus P5Q-E with a C2D and has one HDD on a SATA connection running windows 7 64bit. The old computer is a single core Athlon 2700+ thing with a pair of hard drives on a single IDE ribbon.What I want to do is put the hard drives from the old machine into the newer and be able to choose between Windows XP already installed on the old master IDE hard drive and Windows 7 on the newer SATA drive (I've only kept the old computer to run XP for compatibility), all the while keeping the old slave IDE drive as a slave.

BootMGR Missing - Only When Multiple HDDs Plugged In Not Boot Order

Jun 4, 2012

So I tried installing Windows on my new machine and did waht seemed to be the recommended thing and plugged in only my SSD into the Sata port, leaving my other drives unplugged until after the installation. Everything went fine and I was able to get Windows 7 up, drivers were installing and everything was peachy, but Then I plugged in my other drives, and when I did so with the computer running Windows immediately recognized them and I could access them, as well as do whatever I wanted. However when I restarted I got the message BOOTMGR is missing.

Now, you may be thinking that this is a simple issue of it trying to load from one of those other HDDs, just set the boot order in the BIOS blah blah. But its not. I set the boot order in the BIOS to use the SSD, I set the SSD to the top of the list within the HDDS priority order and still nothing. I then took it a step further and instead of selecting the order manually told it to boot from the SSD flat out, boot from this drive and the same error message came up. I already did the boot from Windows disc, startup repair thing - didn't work.

Delete Vista / Dual Boot Leaving Windows 7 - Separate HDDs

Mar 12, 2012

I would like to remove Vista from my dual boot setup. Here is how I got to where I am now.

I had Vista installed on my PC hard drive (was C. Later, I decided to install Windows 7 HP on a new and seperate HDD. I unplugged the Vista HDD and added the new HDD and installed Windows 7 as if from scratch (I was worried that the install would mess up all my files on Vista). After the Windows 7 was up and running, I then reconnected Vista redesignated it as drive E: and after some searching on how to, I created the dual boot using my Windows 7 disk so I'm assuming the boot file in on drive C: along with Windows 7.

I now want delete the dual boot and Vista so I can use the drive as a backup drive or possibly Win8. I have found several methods to do this but none that really have my specific situation.

After Switching From IDE To AHCI Disk Requires Formatting

Sep 15, 2012

I reinstalled windows, and went with AHCI for eSata hot swap. 2 of my 6 drives did not appear in my computer. 1 of them I just assigned a drive letter in DM and it is fine. The other, which was previously working, says it requires initialization, which I did, and assigned a drive letter. I stopped short of performing a format ( to preserve the data) but it is listed as raw and inaccessible.

I am not sure what to do now as I have a raw drive that I cannot access...which a few hours ago had several hundred gigabytes of data. The drive in question is a 1tb seagate 7200.11. The other thing I did was move the drive from a jmicron controller to an intel controller on the MB. All 6 drives are now on the intel controller sata ports.

Switching Boot Drive From SSD To HDD?

Feb 5, 2012

I built my computer the other day, and I had not planned to have an ssd at all, but somehow ended up getting a 64 gigabyte Samsung SSD. It is very fast, which is good for the boot, and i just told myself i would put all programs on the HDD. I did that, Windows installation took up like 25 gigs, and since then I've been watching the disk space slowly drop. without even putting anything on it. So i need to switch the boot drive to the HDD, i dont know how to do this. Can i just copy and paste the entire ssd onto the HDD? or do i need to install windows on the HDD. how exactly can i accomplish this. I actually prefer this solution because this way i can have all my more used (large) programs on the ssd operate very quickly and just have to have a longer boot time. If you are going to try and change my opinion

[BIOS] Can't Boot From CD-ROM In AHCI Mode

Feb 9, 2011

I'm trying to do a startup repair of Windows 7 x64 on an SSD but can't boot from the CD-ROM while in AHCI mode. I have set CD-ROM at the top of the boot order in BIOS but this is just ignored and the computer boots from the SSD with the knackered version of W7x64. I read somewhere that when in AHCI mode, the BIOS boot order may include "CD-ROM" but it's not the real device anymore. I tried looking for the CD-ROM by its manufacturer name in the list under Hard Drives but it's not there either.So just how do I go about booting from the CD-ROM in AHCI mode? No problems booting if I set the BIOS back to IDE mode, install Windows 7 and then do the registry hack to install the AHCI drivers, but I'd like to be able to boot from the CD-ROM in AHCI mode.

P.S. I have a Gigabyte GA-MA78GM-US2H motherboard and am using the latest BIOS version (F9D)

BSOD During Boot On AHCI Mode

Mar 31, 2012

My motherboard is a Gigabyte Z68XP-UD3 Revision 1.3, my OS is Windows 7 Professional 64 bit, my HDD is a Seagate 1.5tb, and my SSD is an OCZ Agility 3 60gb.

So i was using Intel Smart Response technology with my SSD for SSD caching, everything was pretty much working fine. The other day i flashed my bios using @BIOS without properly disabling my smart response configuration, which i probably shouldn't have done and i won't do again. When i rebooted, Intel Rapid Storage technology was acting up and when i tried to open it, it said "IAStorUI.exe has stopped working". After that, i uninstalled the program and tried to re-install it, but during the install it said "This computer does not meet the minimum requirements for installing the software." After a little research, i found out that it meant that my bios was set in IDE mode instead of ACHI mode. I am not sure what the mode was before i flashed my bios, but it was probably some sort of raid that it used for SSD caching. When i went into the bios and switched from IDE to AHCI, windows would blue screen after performing a few seconds of the boot logo. I switched back to IDE, and did some research to find out about the "Start" registry in HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesmsahci. I switched that from 3 to 0, and windows was able to boot into AHCI mode and automatically got drivers. Then, i tried re-installing Intel Rapid Storage technology. It was able to install, and i rebooted my computer. It blue screened again on the same part of the boot logo as before. I had to switch back to IDE mode to get it working again. Then, i got new chipset drivers from Intel's website, which didn't help. The registry that i changed is still set to zero, but it just won't successfully boot with AHCI like it did the first time i changed the registry. I am very stumped and i dont know what i could do to make it work like it did before i flashed my bios. My friend recommended that i should reinstall windows, but then i would have to go through the trouble of getting everything back and i think there should be some way of doing this without reinstalling the os.

The bottom line is that windows blue screens when the bios is in AHCI mode, even though i have the registry that should fix that and that did fix it on one boot set to zero.

AHCI Crashing Windows 7 On Boot?

Aug 2, 2012

So I just bought myself a Crucial M4 SSD. And the guy at the store told me to make it run even faster to go into the BIOS and turn the HDDs to AHCI. So after installing Windows and playing around a bit I decided to go to the BIOS and do it. But then when the Windows sunburst comes up it crashes. What gives? I was reading somewhere else that there needs to be a registry change somewhere too?

Boot From AHCI CD-Rom: Operating System Not Found

Aug 15, 2011

my computer crashed last night and when I have tried to switch it on since it gives me the above message.I have tried entering setup by pressing F2 and changing the hard disk to be the primary boot device, but the same thing occurs.I have created a Windows 7 32-Bit recovery disk by downloading the iso file on my dad's pc and burning that to a dvd. I am able to load this, but when it first starts up it has a table supposed to list operating systems but it is blank and I cannor select anything. It says if my operating system isn't listed, "click load drivers and install drivers for your hard disks" but I don't know where on earth these are located and neither does google seem to.then working through the option on the menu:

-if I click start-up repair it tells me "startup repair cannot repair this computer automatically"

-if I click system restore I get an error message saying I must specify which windows installation to restore

-if I click system image recover it gives me an error message saying "windows cannot find a system image on this computer" and if I try to select one none appear.

No Boot After Switching HDD Sata Order On Mobo?

Aug 29, 2011

After putting in a second GPU -- which now covers 3 of my Sata ports -- I was forced to switch my drive order around. I was able to boot successfully with 2 of them, but oddly not 3. So I removed my System Reserve drive, setting C: to the active drive, figuring that would clear things up. Then plugged in my 3rd drive into that spot leaving just 2 drives, but windows still does not boot.I checked boot order in BIOS, but I still get boot error.Windows will only boot when I remove the drive leaving only the OS drive.I know a reinstall will solve my problems, but I need to avoid that at all costs.

Switching BIOS SATA RAID/AHCI Setting Causes BSOD At Windows Start

Mar 30, 2012

I just changed my disk setup from:

1 SATA HDD Primary OS Disk
2x SATA HDD Backup Disks in RAID 1

TO:

1 SATA SSD Primary OS Disk
1 SATA HDD Backup Disk
[No RAID]

Everything worked great, no problem. So, since I don't have a RAID array anymore, I decided that I could change my BIOS setting to AHCI instead of RAID. I have a Gigabyte GA-P35-DS3R v1.0 mobo.


These are my steps:Settings > Integrated Peripherals > "SATA RAID/AHCI Mode" = RAID
--> Changed this setting to AHCI Reboot Windows Start screen shows up, but as the color orbs are spinning into focus, BSOD and immediate restart Repeated reboot several times, same outcome
Next Step:Launch BIOS settings Integrated Peripherals > "Onboard SATA/IDE Ctrl Mode" = RAID
--> Changed this setting to AHCI Reboot Windows Start screen shows up, but as the color orbs are spinning into focus, BSOD and immediate restart Repeated reboot several times, same outcome
Switch both settings back to RAID, reboot, and Windows starts up just fine, no issues.

What am I missing? Why can't I set it to AHCI mode without BSODs?

AHCI Mode No Boot From Sata Optical Drives?

Apr 30, 2011

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.

Can Dual Boot With Windows 7 On An AHCI SSD And WinXP On An IDE SATA2

May 29, 2012

I have a SSD with Windows 7 Home Premium x64. To boot off it my bios needs to be in AHCI mode. I also have Windows XP Prof SP2 x84 on a Sata2 drive and too boot off of that I need to be in IDE mode. Also when I boot into the XP drive it rewrites the boot BCD and I need to load up the Windows 7 install disk and do a repair to get back into Windows 7. While EasyBCD will allow me to fix that issue I can't imagine it will allow me to do the whole AHCI/IDE combo will it?

Switching From 'dual Boot' To A Single Partition Windows 7

Jul 28, 2011

I'm trying to install a new hard drive and retire my current one to backup and data storage purposes.

The problem is that I've installed Windows 7 on a hard drive with 2 partitions, an old XP partition (D:) and the new W7 partition (C:). At the moment the disk management screen looks like this:

What I am trying to do is delete the D: partition, and then copy/resize the C: partition including Windows 7 installation to my new hard drive (F:)

If I ignore the new hard drive and just try to migrate to a single partition, I can never get it to boot. I tried using Partition Wizard to set the C: as a primary, active partition, copied over the bootmgr and boot directory, then used bootrec /fixmbr and bootrec /fixboot to try to make Windows 7 bootable from just the C:, but it didn't work. All I got was "disk read error" whilst the PC was trying to boot off the C: (this is with all other drives disconnected...).

I could try to migrate to a single bootable partition from a 'dual boot' configuration?? I tried this video's advice and did everything as instructed but got the disk read error problem.

AHCI Computer Hangs

Oct 27, 2009

me as the most of you is using Windows 7 with so much fun! I do have a little problem,don't know why actually,this is why i'm here asking for help. First of all here is my hardware configuration:

Asus P5Q PRO (latest bios,waiting if Asus is ever going to release the EFI also for my motherboard lol just like happened with P5Q Deluxe,anyway).

In bios options if I select AHCI i get faster performance and system responsiveness,but from time to time,it could happen anytime,i get complete hangs up so i have to hard reboot my pc. I tried EVERYTHING,also Intel sata ahci latest driver for my motherboard and nothing works. This happens with both 32 and 64 bit of Windows 7,and it doesn't seem to happen if it's set to IDE (which definitely makes my computer less responsive). Thanks in advance to anyone that will help me

I'm beginning to thing that it's the hardisk getting insane,it's the oldest hardware component in my pc now.

Boot Hangs On Vye S18

Jun 17, 2009

Anyone managed to get this to work? For anyone not familiar its a UMPC, currently running XP Pro. I created a new partition for Win 7 (x86 RC) and installed it there.

It went through the installation and various reboots until it said it was finished but now just hangs during the final reboot. I've tried safe mode - same thing.

Anyone had more success? Is there anything else I can do during booting or install to try and diagnose the issue? I am assuming its a hardware or driver issue.

I've successfully installed on several other desktops and laptops its just this one giving the problem.

Is it worth trying a newer build?

Windows 7 Boot Hangs On Starting?

Mar 20, 2010

When I boot up Windows 7 it gets to the "Starting Windows" screen which includes the Windows Logo with some animation. Once there it just hangs for about 5 minutes, then starts normally.I have Home Premium, 64 Bit, Dell XPS, Intel i7, 6BG of memory. I have several peripherals connected directly to it: Display, USB External Drive, Webcam, Bluetooth adapter.I tested booting in Safe Mode and it was very fast with no delay.I don't restart Windows 7 often so not 100% sure of when this really began. After the install booting up was very very fast. So this happened over the last month or so.The only hardware item I would mention is a Realtek card/usb reader which is built in to my unit as part of it. After Win 7 install it did not work at all and it took quite a while including working with Dell to finally track down the appropriate drivers. Now the unit works fine but I believe the problem began around that incident.Prior to uninstall or disabling the item I just wanted to check and see if this problem has been seen and make sure I am not going to do something to simply create a new problem. Also, since it was so difficult to finally get this Card Reader up and running I am concerned about just uninstalling it.
