Installation error - unknown disk

Question: Installation error - unknown disk

Hello guys! I'm having a problem installing windows XP on one of my computers and it's starting to get annoying. I tried to install windows XP from the CD and i got this error when it asks me too chose the partition or something: 4 unknown disk (there is no disk in this drive) messages. If i press the up arrow i get a blue screen, if i press enter i get blue screen!

Weirdest thing is, i installed ubuntu on it and it worked. It was running windows before, just so you know! ;)

The HD i'm installing it to is the samsung sp1614c. I don't have any drivers for it, in case you're wondering, nor my computer has floppy drive :|

Has anyone experienced this problem? Thanks for you help guys! :)

Preferred Solution: Installation error - unknown disk

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Installation error - unknown disk

Does this happen when you try and select a partition to install to? I am assuming yes.

The drive you have appears to be a SATA drive. As setup loads you should see at the bottom a prompt to press a key if you need to load 3rd party SATA or RAID drivers. You will need to follow that prompt to load the drivers for your SATA hard drive. That should work.

I'm trying to install a PC with Windows 7 threw USB (2.0). Therefore I've used Windows USB/DVD Tool.
To note, I've installed a NEW hard drive, the old one broke down due to it's age.

Now I'm getting the next message: DISK BOOT FAILURE, INSERT SYSTEM DISK.

I've tried setting the boot sequence but none of that helped, I keep getting the same message.

Thanks in advance,


Answer:Windows 7 Installation error DISK BOOT FAILURE, INSERT SYSTEM DISK

Normally means that the hard drive is not detected. Check its connections, plugged securely into SATA1 port with no others attached, data and power cable securely attached.

Then enter BIOS setup by tapping the key given for that on the first screen. Is the hard drive registering anywhere there? It often will be represented by its Serial Number.

Reset BIOS to defaults, set SATA controller to AHCI, Save settings and Exit.

Hello everyone. I've had this issue for almost a year and a half now. I have been trying to install windows 8 with every way possible, on my main desktop computer without any luck.
I follow the standard procedure. Make a USB Flash drive bootable, reboot, boot from it. After it boots, it shows the Win8 logo, the loading circle, and then, just before the language selection screen, it throws a blue screen for a moment and then the computer restarts. The code is 0x061636932, which is a completely unknown one. Last year when i googled the error code i got no results. Then i created a thread in another forum. Now, if you google the error code, you'll get my thread and another thread from a swedish forum. Bottom line is this:
I have changed motherboards, RAM sticks and GPUs. Tried without any drives except one that would have been used for the installation (SSD and HDD), different flash drives (both UEFI and Legacy boot), DVD-ROMs burnt from a variety of different ISOs (Both Win8 and 8.1, and lately Win10 preview). BSOD persists.

Note that Windows XP, Windows 7 and Linux Mint work completely fine on the same computer. I've been running Windows 7 on it for 3-4 years.

Thanks in advance for any help!

I have tried to download and install Windows 10 quite a few times. It freezes at the point where it has completed 75% of the installation and I think it is just about to 'Restart' once again to go into the final 'Settings' phase. The only way to get out of this that I've found is to power the machine off and then back on again, the system tries to recover the installation and then the previous version of Windows is restored.

You are likely installing XP on a SATA drive, there is an additional step:

However, Most newer BIOS allow an Alternate method for SATA . . Go into the bios and check the "Sata Operation" setting,

change it to "Raid Autodetect/ATA if it is not already. Now try to install XP ( Verbage will vary by manufacturer

some will say IDE instead of ATA)

If there are no such settings you'll need to slipstream the sata drivers on the XP CD, follow the instructions in this guide :

I get the error message below when I attempts to perform a custom installation of
Windows 7 (Ultimate, 32 bits version) on a logical partition of 16 GB formatted in NTFS with a Seagate SATA disk ST3250823AS .

windows is unable to install to the selected location -- error x80040154

I saw that it is possible to load drivers on my hard drive during installation.
The problem is that on Seagate website, drivers are no longer available.

I tried to extend the partition to 20 GB, but it failed too.

Thank you for your help

Answer:Error x80040154 with sata disk during installation

After scanning some Google returns, I found a lot of them regarding other software programs (none like your's), and it appears that it is the Windows installer that is the issue involved mostly. The only thing that comes to mind is the fact that you are trying to install on a logical partition instead of a primary partitition, as it should be. Is there a reason that you can't install it on a primary?

EDIT: Even if you had been able to increase the size of the partition to 20GBs, that is too small. I would recommend a 100GB partition. System Restore points take up a lot of space.

Hi all,

I've been attempting to do a clean install (following the tutorial here) on an HP Probook 5310m, using a USB installation disk created from a genuine ISO (from with the official Windows 7 USB / DVD tool.

The initial phase of the installation ran without any errors but after the first reboot the installation went back to the start (i.e. the "select language" etc. screen) and did not continue automatically. As I was unable to re-start the installation, I decided to take a rest for the night and so shut down the computer, cancelling the installation completely. Prior to the installation I had prepared the HDD via the method shown here, ensuring there was only one partition before I started the installation.

Now, upon power up, I am greeted with the infamous BCD boot error 0xc000000f, even with the same USB disk used previously inserted and the BIOS set to boot from USB hard drive. I cannot boot from the USB disk regardless of its contents (I tried Partition Wizard and a "Repair Disk" I found online). As a result I can't access StartUp Repair, Advanced Boot or bootrec.exe.
However, if I physically remove the HDD from the SATA connector I am able to boot to the USB disk. Installation operates as normal but obviously there is no disk to install to.

My question is: how should I proceed from here? To my mind, there are 3 options :Buy a new HDD

Answer:BCD Boot error 0xc000000f while booting from USB installation disk

Actually, now that I think about it, inserting the HDD after booting probably wouldn't work as all the hardware has been scanned and initialized by then. If anyone has any other ideas they would be much appreciated!

I've been trolling the forums here for a while. Lots of great info but now I actually have an issue where I need some assistance.

When I was booting one day last week I got a nasty BSOD when Windows was trying to load. Then on the next reboot Windows 7 said it couldn't load and needed to do the recovery OS option from the Windows 7 repair on the CD. Well, before trying that I did a cold reboot and it got back into the OS fine so I didn't think much of it. Now, I noticed Ghost shows the C: drive status as "Unavailable" and it can't back it up anymore. It does give me an option to restore from one of my old backups. I'm thinking the MBR got hosed up somehow or something like that. But I'm skeptical to run an MBR repair since I have that 100MB partition on my SSD where my OS resides.

This was about a week ago my Windows 7 started acting up right before the big patch Tuesday. I've been running it for over a year now and it's been solid. When I first set it up I installed it on my SSD (Intel 510 120GB) drive. One of the qualms I had with the install is Windows created a separate boot sector on the disk drive where it stored my boot files. This is known the the "system reserved" operating system files 100MB partition. Apparently the way to avoid this is to use a third party partition tool before doing the windows install. That way it will keep the Boot sector files on the same partition which is how I would of liked it for doing resto... Read more

I'm running Vista Ultimate 64 on a 500 Gig hard drive with 3 partitions.The problem is I marked one of the partitions,not Drive C, as "active" by mistake.I done a Command Prompt to make it "inactive", but when I started the system up again it wouldn't boot.I used the Vista disk for the recovery process, but I got a message "Operating system unknown on (unknown) local disk" i tried fixing the problem with a command prompt "bootrec/fix boot" ,but nothing happened.When I look at the info in Command Prompt it doesn't show the disk partitions, just Disk 0.Also I can't repair because no Disks are listed to be repaired. If I look at the drive in "My Computer" it is full with a file system marked as "Raw" and it wants me to format the drive.I used "Recover My Files" software and it shows some of the documents that are on the drive, but doesn't show any recovery.I looked at some internet post about the message I got and partition and boot problems like I have, but at this point I don't to try any else to make it worse.I would do a reinstall ,but on one of the drives I have some stuff that wasn't backed up.I never thought about backing it up because it wasn't on the C drive.Any help to solve this problem would be appreciated. ..........Kumpie

Hi,Bought a G510 running w8.1 in May.  After 3 months of untroubled use I started getting all of the above error messages and problems. Restored to factory image. updated bios and updated drivers problems still persisted, all hardware tests were fine. Contacted Lenovo, laptop needed to be shipped to Germany, from UK as it appears there are no facilities in the UK??, to be examined.  The solution... Lenovo replaced the hard disk. Laptop was working fine again until a couple of weeks ago (about 3 months elapsed since original repair!!)  and exactly the same problems have returned.  The joke is I dont even use the laptop seriously as I dont trust it, and it spends 99.9% of its life as an expensive web browser machine. Surely the drive hasn't failed again, are they really that bad, or does the real problem lie somewhere else? Either way I'm totally unimpressed, no doubt having to send the laptop off for another 10 day holiday in Europe. :-( Anybody got any suggestions whats happening here?  Many thanks

Answer:G510 SATA disk on Controller 0 Port unknown, IQRL not less or equal errors plus 100% disk usage

Maybe you can have someone analyze dump files and figure out what's causing this issue.  You can wait for one of the staff to reply or you can ask at Microsoft Answers as well.

I have run into a problem that has been causing me quite a bit of headache as of late. A week ago, my WD Elements External Hard Disk is not displaying under hard disk drives, but does display under Devices and Printers. This is what it shows under computer management:

I have tried to initialize the disk using MBR and GPT options but failed receiving I/O Disk Error.

Sorry for a long post, but the problems have been mounting and I want to be clear with what's wrong...A while ago my computer stopped functioning. After playing a game, I left and came back to find the screen black, so I hit the hard restart button, and it got to the screen with the Gateway logo but when that ended and it should have flashed to the Windows Loading screen, it just went black with a blinking white _ . I tried hard restarting several times, and each time it would go to the black screen with the white blinking _. It shows the BSOD. Even trying Safe Mode only got me a little bit farther - I could get past the gateway loading screen.Finally I decided the best thing to do would be to reformat. Here is where my current problem lies. The drive is plugged in properly and is brand new, so I know it's not a dud. But, when I boot up with the Windows XP Home installation CD and get to the point of selecting which drive to install Windows on, the options is: "Unknown disk (there is no disk in the drive".Once again I tried to install Windows, and it gave me the same message (Unknown disk). I thought for a moment that maybe it was because the hard drive was bad, so that?s why I bought a new one. When the new one came in the mail, I put it in and the same problem happens.So now I'm at an impasse - neither of my drives, one of which worked fine not too long ago and one of which is brand new, is being recognized by Windows setup, and I don't know wh...

I'm trying to install Windows 7 Home Premium on an old underpowered Dell Dimension XPS T700r with a P3 chip running at 700 MHz, 768 Mb Ram, and an old ATI Rage Pro 128 display adapter. It runs XP Pro just fine.

All seems to be going well as Setup copies and expands files until the first reboot, when I receive "Disk Read Error, press Ctrl-Alt-Del to restart". This occurs using several different hard drives of sufficient capacity. It also occurs when I try the installation from a flash drive after mounting the Windows 7 ISO on Virtual Clone Drive from within XP. I've tried to install Windows 7 Starter but it, too, chokes at precisely the same point. I've tried all this on an similar machine with comparable but different components. Same result with all these attempts.

I know I'm try to push the envelope in a downward direction here; Windows 7 Upgrade Advisor issues the standard warnings on processor speed, ram, and display adapter, advising that any installation will be sluggish and that the graphics adapter will not support Aero. But I'd like to see how sluggish.

Any ideas out there as to why this install is choking where it does?

I got a new PC tonight, custom-built (from eBay) and I've been attempting to install Vista Home Premium x64 for the last 4 hours!

It supposedly had Vista pre-installed and was "ready to run" but the seller was obviously a liar. Because when I turn it on, this is what happens:

- a 'Biostar T-series' visual appears on the screen for a second (I don't know what that is)
- it then goes to a command screen with 'Hardware Monitor' and lots of CPU details

it then says:

Verifying DMI Pool Data ........
Boot from CD:
Press any key to boot from CD or DVD.....
A disk read error occurred
Press CTRL+ALT+DEL to restart

If I do press a key before the disk read error message appears it does bring me to the Vista installation screen. It then does install Vista, but when it gets to the point where the system needs to reboot, it just brings me back to the same command screen again.

I've tried to format the hard drive, and even attempted the system repair method (it found no problems with the system startup apparently). After I do the system repair process, instead of "A disk read error occurred", I get "BOOTMGR missing" instead, whatever that means.

At present, the computer is unusable, and I'm kinda pissed off cause I've wasted a whole night on this and will probably do the same tomorrow.

Any help would seriously be appreciated - thanks.

Answer:x64 Installation problem - "disk read error"

I recently built a new PC, however I'm having a problem installing Windows XP onto my SATA drive. It works perfectly if I use an IDE, but this is what happens with SATA:
-Goes to the setup screen and puts on the necessary files.
-Asks me to format.
-Starts the 15 second restart timer, then restarts.
-I change the boot order to HDD first.
-It tells me "A Disk Read Error Occured. Press CTRL+ALT+DEL to restart" when it's supposed to continue with the installation.

I've tried the drivers that came with the motherboard and no-go. I've also tried with no drivers and it still gives me this error. One time, I believe it said something about "Boot", but it flashed on the screen too fast and restarted to see what it said.

EDIT: If I made a direct copy from an IDE drive onto this SATA one, is there a chance that might help? If there's a driver issue, it would have all the drivers needed on the Hard-Drive wouldn't it?

Motherboard: Asus A8N-VM CSM
Processor: AMD Athlon 64 3700 1MB L2 Cache
Case + Power: Antec Sonata II 450w PSU
RAM: Crucial Rendition 1GB PC3200 x 2
HDD: Seagate Barracuda 300GB 7200RPM 16MB Cache SATAII
GPU: Radeon 9600 XT AGP

Answer:Solved: SATA installation in XP = "A Disk Read Error Occured. Press CTRL+ALT+DEL to restart"

Fixed it simply by making a clone of my IDE drive on my SATA drive :-].

Hi Guys,

I spent the last 3 hrs looking for a solution to this, but nothing has worked. I have already installed Windows 7 on a very similar system but never encountered any problems...

I have built a new system (everything new):

- Gigabyte E350N with CPU on board
- Kingston 2 GB DDR3 RAM
- Verbatim 64 GB SSD

The SSD is OK in the BIOS. I then install Windows 7 using a USB drive (which has worked before for 3 other installs). Windows 7 installer finds the SSD and installs without error. Then it comes to the restart:

"Disk read error"

No matter what I do, I can't get rid of it. I tried the following:

- Windows 7 recovery (also performing it 3 x in a row) finds no problems
- Deleted all partitions on the SSD and reinstalled
- Formating the SSD again
- 3 different SATA cables
- All 4 SATA inputs on the motherboard (shown as Master and Slave in BIOS)
- Optimized settings in BIOS
- Fail safe settings in BIOS
- IDE vs. AHCI in BIOS

I am lost. I don't know what else to try. It is just possible that my brand-new SSD is broken? Then why is Win7 installed without error until the first restart?

Thanks for your help!
Windows was always installed on D: with the 100 MB C: partition, so I also tried the "get rid of the 100 MB" trick. It works (Win 7 installed on C: without the 100 MB partition) but the same problem.

I'm not positive, but I'd guess a $14.99 price for Win 8 would be a download, unless Samsung is offering some special promotional price for a disc.

I've seen a price of $69.99 for Windows 8 Professional, which I think is for a disc.

I'd find out what that $14.99 price is good for. It may be for an ISO download, in which case you could burn the ISO to a disc.

I'd keep the Windows 7 disc regardless. If you are like most people, you probably will find 7 preferable to 8.

Hi there,
first off I wasn't sure where to post but my guess is it's a driver problem so that's why I started the post in Drivers section. So here's the brief story..

I'm presently running Windows 7 and I'd like to switch to Windows Vista 32 bit. I have both Vista Home Premium and Vista Business, however the two CD's won't read, neither while logged on windows, or when I try to boot the disk after bios booting (yes, I set CD/DVD drive as first in booting sequence).

I'll say in advance, I deleted the windows.old folder so now I can't revert to Vista that way.

I would say it's the CD/DVD drive, but I've inserted other CD's/DVD's and they were read completely with no trouble. As well as, I'd say it's my Vista disks that are bad but the business disk was sealed in the original "paper cover/container", therefore there are no scratches or damage to the disk.

I want to also mention that windows update is up to date.

I'm running on a Dell Studio 1535, any thoughts on what might be preventing me from reading and installing Windows Vista?

Answer:Vista installation disk not reading, DVD drive AND DVD disk is good

I want add that another thought of mine is that the disk won't read until the hard drive is completely wiped, but I'm not sure if that's how Vista installation disks are configured and if wiping my hard drive will help..

Move windows 7 installation from one disk partition to other disk partition
HI all ,

Before going into details of my problem, I am listing down my system setup.

I have 3 HDDs on my pc with following details :-
1. Disk 0 - 500 GB - Windows 7 32-Bit Installation on C: - Partitions ( C - H)
2. Disk 1 - 1 TB - Windows 7 64-Bit Installation on J: - Partitions ( J - N)
Here I want to mention that, my Win 7 64-Bit installed on J: , and my linked documents folders reside in K: under folder K:\MyFolders ( as shown in K_myFolder.jpg)
3. Disk 2 - 1 TB - No OS on any partition - Partitions ( O - T)
As shown in attachment DiskMgmt.jpg

Now my problem is, windows 7 has detected some fault in Disk 1, thus I need to send the Disk 1 for RMA. So for the same I need to move my Windows 7 64-bit OS installation from Disk1 - Partition J: to Disk 2 - Partition O:, and data folder Disk 1 - K:\myFolder to Disk 2 - P:\myFolder.

How can I do with keeping the settings as mentioned above. How does my OS References will be remained for the requirements.

Thanks in Advance.


Answer:Move windows 7 installation from one disk partition to other disk part

We need to see the labels which are obscurred in the Disk Mgmt columns, nor can we see how much space is used on K you want to move to the smaller P.

You want to use Disk Imaging.. I would use free Macrium Reflect which offers more flexibility where to reimage the partitions you choose to image. Macrium - Image your system.

However if you have a WD or Seagate HD in the mix, you can use their premium Acronis imaging app which is best of all, and has a very easy to understand Manual on it's download page on either HD maker's site.

After imaging if the OS fails to start on the new HD, unplug all other HD's, confirm the OS is marked Active, then run Startup Repair - Run 3 Separate Times until it starts and holds the System flag. Then set preferred HD to boot first in BIOS, boot other one using one-time BIOS Boot Menu key.

Hi Nitin,
The Windows product key is pre-installed in Dell systems. However may I know the reason why you are looking out for a disc?
If the computer is not booting up and if you want to request for a disc then you may use the below link:  (For U.S only)
If the system is working normally, you may create a system restore disc by following the below steps in Windows 8:
(1) Move to mouse pointer to the top right corner and click on the search button.
(2) Select applications, type Dell backup and recovery and select search.
(3) On the left side you may click on the application.
(4) Once the application opens select recovery disc and create rescue disc.
OEM discs (Win8) can be installed on any Dell computers (if Windows 8 is pre-installed in that computer from factory).
It is suggested to use OEM image for re-installation purpose.

Hi All,
Recently bought an A7 and was convinced all the pre-installed Toshiba software was slowing things down. Managed to fresh install windows then use the Toshiba Apps installer to restore the components I actually wanted. All has gone well and the computer is about twice as fast now. However I have the following two unknown devices:

1) Device Type: Other Devices
Location: on Intel(R) 82801GBM (ICH7-M) LPC Interface Controller - 27B9
Hardware ID: ACPI\IFX0102

2) Device Type: Other Devices
Locations: on Microsoft ACPI-Compliant System
Hardware ID: ACPI\TOS620A

I have installed the latest Intel Chipset drivers and no luck. Perhaps one of them is the sound card (although I have installed those drivers as well), and one of them the HDD Protection (which I have no intention of installing anyways).

If anyone can confirm what they are it would be much appreciated.

Kind regards,

Answer:Tecra A7: Two unknown devices after Win OS installation


The Toshiba drivers and utilities installation should be done in the right order.
The chipset utility should be installed at the beginning and then the common modules.
You should use the chipset form the Toshiba website.

The Tecra M7 supports also the HDD protection. Usually you should find it at the last position under "sound, video and game controllers" in the device manager.

Answer:Tecra M7 Unknown device after Win XP installation

Since I don?t know what devices you mean I cannot provide you any information about needed drivers?

You are talking about Ethernet driver? you are meaning the WLan or LAN?
Usually both cards (Wlan & Lan) should appear in device manager -> network adapters
If there is an unknown device then this would mean that one of the drivers was not installed.

On the Toshiba European driver page you will find two Intel LAN drivers.
Check both!

I don?t know what Wlan card your notebook has because the Tecra M7 has been equipped with different Wlan cards but all drivers (Intel, Atheros) are placed on the page and you should try it!

Let it be known that I have done this before for many years on many different computers, and never had this happen before.

so here's how it went. Bought it two days ago, PC came as is with OS loaded with software that I didn't need or want. Decided to re-format, now I get a butt-load of errors during install. (80+ at most, and never the same).

Formatted NTFS on the two HDD's I have, rebooted, Primary Unknown, Secondary NTFS, booted recovery console and ran FIXMBR and DISKPART and both said NTFS. Booted back into XP DOS setup, primary unknown, secondary NTFS.

Tried install on secondary MBR, same 80+ errors and that's when I had to head to work.

If anyone has any ideas, please reply, will check in tomorrow.

it's not the HD's, I just bought one of them and the other was booting XP before all this. And I don't think it's the board, because it would not have booted XP in the first place

I have a Toshiba Satellite U300-14Q (Model PSU30E). I installed XP, but there are 2 unknown devices:

- Controladora de memoria PCI - In English: PCI Memory Controller (I suppose...)
- Dispositivo desconocido - In English: Unknown device.

I have installed all the drivers from Toshiba and Microsoft. What are the missing driver?

Greetings from Spain.

Answer:Satellite U300 - Unknown devices after WXP installation


- PCI Memory Controller ? Missing Robson module ? this is not offered for WXP and this will always be listed in device manager. It should not disturb you at all.
- Unknown device ? I am afraid you have forget something. I do not know what but it can be card reader controller or maybe password utility.

Please be sure you have installed all listed stuff following ?Installations Instructions? document. The installations order is also very important.

Satellite A200 PSAE6E.
Installed Windows XP instead of Vista.

Everything is fine instead of one thing. Device manager shows that PCI Memory controller is unknown device and showed in question mark symbol.

What sould I do? I think i installed all drivers that were possible to download from Toshiba support.

Any suggestions? Really appreciate.


Answer:Satellite A200 - Unknown device after XP installation

You will never find a driver for PCI memory controller on XP.
This hardware is only supported by Vista and so you can ignore this yellow exclamation mark.

By the way, this I have found on the Toshiba website:

Hi All

I havve an L350-203. The problem is it went astray, and somebody wiped the hard drive.

I have the OEM XP Pro disk (i retrofitted it over Vista for networking) but the Toshiba systems disk is missing with all the motherboard drivers on it. Result - a long list of "unrecognised devices".

On the Toshiba tech support, none of the models correposnd - they are all like L350-2701 or 2021 or similar. Nothing for 203

Can anyone help as to what model it is?

A million blessins for any help - I reall miss this machine (using a other unit instead - a pale imitation!)

The Satellite L350-203 belongs to the PSLD8E series and the drivers for this series can be found on the Toshiba European driver page.

Please check this and you will find the Win XP

Hello forum,

I succesfully installed Win7 in my brand new NB10-A-10V.
This was made possible thanks to BIOS 1.60.

As far as I can tell everything works OK and have found all the familiar features and behaviour provided by Win7.
But the Win7 installation is not perfect yet; there is a missing driver, as signaled by the Device Manager:

*!* Controleur de codage/decodage PCI +(sorry my Win7 is the French version)+

Its ID is PCI\VEN_8086&DEV_0F1

I have no idea what is controlled here since as I said I did not notice any problem with my NB10 and/or Win7.

Can anyone tell me what is this +Controleur+ ? And just for the sake of pleasing Device Manager, can anyone point me to the missing driver?

All the best, Matitic

Answer:Satelllite NB10-A-10V: unknown device after Win 7 installation

According to the info from PCI database
The VEN (vendor) ID means 8086 and DEV (device) ID seems to related to chipset driver or USB Driver

Both can be found on the Toshiba EU driver page

Today I installed VBox on my Windows Vista (I know) because I need to to try some things out.
Right after my installation was complete and perfectly running, on my host machine the Network Adapters are listed as "unknown" (my interface is in Italian, here they're listed under "sconosciuto" instead of "schede di rete".
Moreover, if I try giving the "getmac" command, it says there's no network adapter.
Then, I decided to try uninstalling the devices, but when I click on the "uninstall" command, a message saying something like "impossible to download the NET installation program. Try contacting the hardware vendor".
I tried the system recover point, but that was useless too.
I even cleaned the register, but it was useless.
The funniest thing is: even though it says all this stuff, the wlan and the lan connection both works.
The thing is I wanted to know my MAC address, but couldn't get it.
What can I do now? Is formatting the only choice? Please, help!
My wlan adapter is: Atheros AR5007EG and the lan is: Marvell Yukon 88E8055 PCI-E Gigabit Ethernet Controller.

Answer:Re: "unknown device" on Portege R500 after XP installation

Install simply everything from the Toshiba page.

But possibly you are speaking about the PCI memory controller.
It?s Intel Turbo Memory also called Intel Flash cache logic chip. It is quite new technology designed to support new Vista capabilities and XP doesn?t supported it. Therefore the unknown device in the device manager

Hello, I have been trying to unistall AVG all morning but it can't complete as there's a installation running, but to my knowledge there isn't another one running and I can't work out what it is? It's not a problem with AVG as iv'e tried unistalling other programs and they say there's a installation running to. Anyone got any ideas how to stop this mystery installation? Thanks

Try this.

Right click on the window in the bottom left of your screen; or right-click on the task bar and open Task Manager. Look down the processes tab for AVG. Right-click to "end task. " It will give you a warning. Ignore it and end the task. Now try the uninstall.

i just installed Windows XP on a Satellite U500-115 (PSU5EE) and can't get rid of several unknown devices in the device manager.

Before installing the operating system i switched the AHCI-Settings in BIOS to Compatibility-Mode(IDE), so i don't need to inject SATA-Driver during the installation.

These are the unknown devices:

ACPI\PNP0C32\1 (Location: Intel ICH9M LPC Interface Controlle - 2919)

ACPI\PNP0C32\2 (Location: Intel ICH9M LPC Interface Controlle - 2919)

ACPI\PNP0C32\3 (Location: Intel ICH9M LPC Interface Controlle - 2919)

ACPI\PNP0C32\4 (Location: Intel ICH9M LPC Interface Controlle - 2919)

ACPI\TOS6205\2&DABA3FF&0 (Location: Microsoft ACPI-Compliant System)

Of course i installed chipset driver and graphics driver from toshiba download page, but the unknown devices are still there! Can you please tell me what kind of drivers i need to install the ACPI-Devices and get rid of these unknown devices?

Thanks in advance,

Answer:Satellite U500-115 - Unknown Devices after Win XP Installation


In my opinion the unknown devices belongs to the SATA interface controller and these appears as unknown device because you have installed the XP in compatible mode.

Try to install the Intel Storage Manager driver.

The ACPI\TOS6205 device might be a Bluetooth device.
You need to install the Bluetooth stack in order to get rid of unknown device.

Furthermore you should check if you have installed the MS WinXP SP2 and the Intel chipset Utility.

Now i've downgraded to XP my self and installed all the drivers i could find from the toshiba website
I still have these problems:

1. I have a pci memory controller that is not identiyfied by windows and i want to resolve that

2. When i connect my video camera trough 4 pins firewire to my laptop does not found and when i do it by ieee1394 to usb, i get usb device not recognized (trieed downloading drivers for the cam but they did not work)

Please help me :)


Answer:Satellite A200 PSAE6E: unknown devices after XP installation


Regarding the point *1:*
The "PCI Memory Controller" or "Mass Storage Controller? means the Turbo Memory former Robson module. This feature is available only in Vista and therefore the drivers are not available for Win XP.

Check this:
[No Windows XP driver for PCI Memory Controller|]

*2)* I don?t know how it works with you camera but I needed to install firstly the cam drivers and then I have connected the camera to the notebook using an firewire-to-USB 2.0 cable and then I enabled the video camera.

G'day all.

I have an A600 (Vista original) which I recently installed to Windows 7 Professional 32 bit (reformat/reinstall). I was careful with the order of installation. All is fine except the inbuilt camera does not work and there is an unknown PCI Simple Communications controller listed in device manage. Undoubtedly the two are linked.

I have tried reloading the chipset drivers to no avail. The unknown device is PCI bus 0, device 3, function 0. Is there any way of determining what this device is so I can track down the missing driver?

Answer:Portege A600 - Unknown device after Windows 7 installation

Hi buddy,

Can you post the vendor and device ID of this unknown device? This would be useful to identify it.
=> [How to identify an unknown device (e.g. Wireless LAN module)?|]

But PCI communications controller could mean the webcam? In your case I would try installing the webcam driver from official Toshiba website. After the installation you should be able to start the webcam software and use the webcam.

As far as I know the batteries entry should have a "Microsoft SMART Battery" & "Microsoft SMART Battery Subsystem?.

If there is an unknown device this could have something to do with Microsoft ACPI Compliant Embedded Controller.
In such case it seems you need a driver for MS SMART Battery & MS SMART Battery Subsystem.
