"No boot device detected" after RAM upgrade

Q: "No boot device detected" after RAM upgrade

Dell Dimension E521, BIOS 1.1.11
AMD Athlon 64x2 Dual Core 3600+ 1.9 Ghz
RAM: 512 mb stock/2.5gb w/ upgrade
HD: Western Digital Caviar SE 80 gb

This RAM upgrade has really messed my computer up. When I first installed the new RAM, I got a black screen on startup. No POST, no beep, nothing. Reinstalling the original RAM in its original slot did not help anything.

So I removed the motherboard battery to reset the CMOS/BIOS and reseated the RAM a couple of times and finally got it to boot to BIOS. I then reset the time and date and the boot sequence.

But every time the machine tries to boot to Windows, I get "No boot device detected, insert system disk and press F1 to continue or F2 to setup."

It will not boot to the XP setup disk in the CD drive. It will boot from a Windows 98 boot floppy.

I have gone into the boot menu and run disk diagnostics, and the boot drive passed. I have also upgraded the BIOS.

I'm at a loss where to go from here. All help is appreciated.

Preferred Solution: "No boot device detected" after RAM upgrade

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 http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: "No boot device detected" after RAM upgrade

"RAM: 512 mb stock/2.5gb w/ upgrade"

2.5GB? Are you using two 1GB sticks and one 512MB stick or something? To my knowledge RAM has to be installed in equal portions, either filling all your slots or only using enough to get to 512MB, 1GB, 2GB, etc.

Installing it any other way could result in either the motherboards' failure to detect the RAM, or damage.

Problem I was having once I completed my new build with old system parts was as listed in title. It started out as select proper boot device, and now it states ntldr is missing. From what I have been reading it seems as if my partition with my windows 7 install is not set active. I do not have my windows 7 DVD only my old vista DVD. I tried to boot into it to make use of CMD and attempt to make my partition active but I was unsuccessful to even get into CMD. I went into bios and forced booted from the drive with the OS and still same error, also I attempted to disable the other sata and run the computer again with no success also. Look forward to hearing from someone soon. I will be sitting by my laptop all night until this computer gets running.

Finally Got to command prompt but it shows my current drive listed as x: dunno if this will be relevant and helpful to anyone.

I just recently had a problem with my main hard drive which had a capacity of 20gb and so i decided to take it out and leave my second hard drive ( which was 160GB) in the system. But now i have the problem where the computer asks me to "Reboot and select proper boot device or insert boot media in selected boot device and press a key" after 30 seconds of turning on my computer.
What do i do here?
I am completely lost.
Please help.

A:"Reboot and select proper boot device or insert boot media in selected boot device"

Hello Vinroy

You have removed the "Master" drive which XP booted to.
Now you will have to make the 2nd drive into the "Master"

Connect this 2nd drive using the connector which was used for the drive you removed.
Then change the jumpers on the drive to master.

I have had my computer since Christmas, It has been working fine. Then I went on this morning as normal as can be, everything was booting up and I opened steam but it said no connection. Then a blue screen appeared and said something like" search DHP watchdog violation" then the screen went black but displayed the text "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key"
I have no idea what to do and I need help. I searched this on tech guy and I tried to boot it with my CD/DVD Drive off which is what I saw worked on another persons thread but to no avail. Please help, also I use windows 8.

A:"Reboot and Select proper Boot device or Insert Boot Media in selected Boot device.."

The "DHP watchdog violation" could be caused by any number of things, typically within the OS. Which is a non-issue now since the PC won't boot.

What error do you get now when you try to boot? If it's the same or similar to "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key", then it sounds like the HDD (which is the primary boot device) cannot be found. Which typically indicates a HDD failure, but could also be just a loose/faulty data or power cable.

Enter the BIOS and verify if HDD is recognized properly, and if so, verify the boot order.

That dxdiag "no sound card" message is misleading as I've found it says that if no driver OR sound card. I think you're missing the right driver

Also, it would seem from your post you have High Definition (HD) audio. Which means you'll need to find the right High Definition audio driver. (AC97 pre-dates HD audio so the Realtek AC97 couldn't be right)

Try starting on the HP support website HERE and enter your model number or they have a button where they'll try to identify your product and drivers for your model. They should list an HD audio driver there

Mods, if you feel that this thread is more of a "Windows" issue, please feel free to move this thread.

Here last year I did my second build because I was having "boot" issues. Wasn't certain what exactly the problem was at the time. But something some how screwed up the boot sequence in my system, and where everything was pretty much "outdated." I just went ahead and did another build.

Though, since then I've been pondering around with the thought of using a SATA to IDE adapter so that I can retrieve what ever salvageable data I can from one of the two HDD's that was in my last build. So I finally broke down and ordered a couple different one's earlier this week.

Unfortunately, I've been running in to some problem(s) when I try to launch with the IDE in place.

Upon initial launching, the boot sequence seem to take some time longer than it normally does with out the IDE HDD in place. Though after a 15-20sec lapse I'll get an error screen displaying an windows error code of "0xc000000e" with a prompt message below stating "The boot selection failed because a required device is inaccessible"

I searched all over online to see what that error code represents, only to get "pages after pages" of sites with each site telling me something different.

I have no intentions of using this as a third HDD in my system. I just want to retrieve select data from it.

This is apparently a common problem with no single answer. Regardless of whether any USB is plugged in or not, the system will give this error after POST. I can't get it to go to BIOS, pressing Delete at the mobo screen does nothing.

A:Asus motherboard "USB Device Over Current Status Detected"

I just did a search for this error and I see what you mean, there are dozens of different solutions. Had you made any changes just before this occured?

I think the best place to start is to begin by disconnecting everything from the mobo apart from one memory stick and the monitor. This includes disconnecting the hard drive/s, CD drive/s, keyboard, mouse speakers, printer, any USB device and unplugging the cable that goes to the front USB connections (if you have any) any cards including graphics (unless you have no onboard graphics to connect to the monitor) and any card readers or floppy drives. Then try to boot and see if you get the post screen or that error again.

Let me know what happens.

Here's the full text of the dialogue box which is popping up:

Your TouchPad has been disabled because the Synaptics TouchPad driver has detected another pointing device plugged into your computer.

And then sometimes, for a few moments, my cursor gets a mind of its own and appears here and there all over my desktop.

But my mousepad isn't disabled: it continues to work just fine. I LiveUpdated Norton and ran all the scans, updated XP, and downloaded Widestep Elite Antikeylogger. Things were OK for a few hours, but then the "disabled" prompt and funky cursor for a few seconds.

Over the past day or so the window would pop up within ten or so minutes of a startup, so making it go away for several hours was better than what I had, but still. . .

I removed the drivers for my Gyration keyboard and mouse. While everything was loading at the next startup a box from the antikeylogger popped up and it said:
Name: unknown module
Type: Files and processes monitoring
Home Page: No information
The "warning level" was pegged.

But I allowed it for one session just to see if the problem was the Gyration software. Sure enough, an hour or two later I got what I suppose to be an attack.

I re-started, and this time the keylogger showed two more prompts in addition to the one I cited above. One said "Keyboard monitoring" and the other one I don't remember exactly but it sounded like part of a keylogger malware app.
I blocked all three, but th... Read more

A:"TouchPad driver has detected another pointing device..."

This problem with my laptop continues.

I ran the Secunia program, removed all the old versions and installed the latest ones, and I'm still getting this prompt about my touchpad. Only happens when I'm online and it usually takes 10 or 20 minutes after startup b4 it happens.

I'm worried about two things: the possibility my laptop is under attack and that I've said something wrong in this forum and that that accounts for the lack of any response to my post. The latter is of greater concern to me.

Is this concern well-founded?

I've been away from home and I don't have my laptop with me, but I was reading a blog this morning and I came across the word troll. Never had seen it used like that b4, did a little research. I have zero information about the thinking which informs the response to this post, but the troll thing reminded me of that "0" in the "Replies" column. I always tell people they should never deny things they haven't been charged with, so I'll say this: I'm a novice user who thinks his computer has been attacked and wants some advice about dealing with it. That's it.

I thank you in advance for any and all help.

And Windows Media 10, it states "No device detected". I basically want to know what does this all mean? How can I locate my CD burner and make sure its properly attached?

I'm not truly the best with computers, and this is a new pop up for me. I just purchased this new dell laptop in May and have had no problems with it. However, in the last few weeks I've been getting a new pop up in the right hand corner. My house hold have a wireless router that is password protected. I have McAfee Security Center updated, and shows that all my firewalls and security systems are on and active.
However, this is the message I get and I'm concerned about my networks safety:
"Unknown PC or device detected
This PC or device has connected to your network:
IP Adress xxxxxxx"

I've opened my action center to make sure everything is okay, and the only thing I find that isn't turned on is the "Network Access Protection" - which is something I haven't touched before, nor does it provide a link in which to turn it on. However, in browsing other forums I've found that everyone says turning it on isn't necessary or important.

Looking for help on my issue, and would like to know if the message I'm getting means my computer is at risk.
Thank you in advance!

A:"Unknown PC or device detected"

Hmmm... since no one has responded yet, I'll ask a few questions. So, are you using a router and a wireless connection to access the internet? If so, have you set up router security so a password is always required for anyone trying to gain access? Also, can you go here and do this simple test to see if you have any open ports that are vulnerable to inbound intrusion attempts? Here's the link and here's my results:

Now right off the bat, when I installed it, and it tried to install the PC friendly software for DVD movies (that comes with the PC) it gave me and error just before it finished installing. Gave me one of those "Send Error Report" that gives you the option to send to microsoft. But then when I closed the program, and popped in a DVD movie, it played well. So I moved on, but when I installed software for my Palm, and tried to do a hotsync, the palm did not connect with the desktop software. I kept getting a message on my palm that "device cannot contact your desktop" So I checked the Com Port 1, (where I had connected the cradle to) And everything looked normal (to my knowledge). I tried re-adjusting the cable, made sure it was connected correctly, and changed the com port from 1 to 2, 3, & 4 and none of them would detect my palm. (I was able to do hotsync on my old pc-Win 98) So I took my digital camera, and connected it to the same serial port, and installed all the software, and it did not detect it either.

Hi, I'm trying to reinstall my sister's scanner driver because XP has decided that it's not there any more. This happens occasionally and usually reinstalling the driver fixes it (I think that's what I did last time), but this time i just can't get it to work.

If i unplug the USB cable then plug it in again, it comes up with a message saying that the device has malfunctioned and it doesn't recognize it. I have the driver CD but windows always manages to install it as "Unknown device" before i can tell it to search the CD. I've tried telling it to reinstall the driver from the CD but it says that there are "no better matches for this device". I've also tried uninstalling the program form the CD and reinstalling it then restarting the pc but that didn't help either. I tried plugging it into another USB port (as suggested by Windows Help Center) but that still didn't work.

It's not often that something like this gets me in a circle and scratching my head but I'm really starting to run out of ideas.

I've tried using my recovery disc to use Startup Repair but my partition seems to be missing and when i use bootsect to look at my disk volumes it is also missing in there. When I try to restore my computer using a Windows 7 install DVD it only shows my "Backup" partition. I've also tried reordering the boot order in the BIOS.

A:"Reboot and Select boot device or insert boot media"

It would appear that your hard drive is having problems. First of all, do you have a current backup of anything important on the drive?

I have run webroot antivirus with antispyware, several times. Every time I do, it finds the same virus (sometimes others with similar names). This is from the latest scan:


and some cookies. However often I quarantine them, they reappear on the next scan and I also can't get the desktop to go back to its normal appearance, it's gone white with a big warning (as above) and refers to:

I just replaced the stock xtremegear psu my computer came with because one day the computer just shut off and wouldn't turn on again.

I replaced it with a corsair gs800. I'm pretty sure I plugged everything in...the 24 and 8 pins into the motherboard, and the pci-e into the graphics card...as well as the fans and the cd drive.

When I turn it on, it goes through MSI's start screen but then it tells me something about No hard disk detected. Then it goes to the MSI screen again and gives me a choice to boot with...but there's only one choice, cd/dvd atapi drive. I choose that and it doesn't work.

I double checked the connections I have plugged in and those are secure. there are lights flashing on the motherboard so that's getting power. That's the 24 pin one right? I also checked the one in the corner, the 8 pin one...seems to be secure. They both clicked in.

Could someone please tell me what I might have done wrong?

Oh and here's the computer information that came with my invoice. Ignore the PSU, it now has what I said.

The hard drive is a Western Digital 320 GB that I've had plugged into this computer before (and worked). Then i got a virus and had to do a recovery of windows.

Ever since then I can't get windows to recognize/show it in my computer. I just "disabled" and "enabled" it in device manager to no effect. I have a C, D, and E drive which are: two partitions on the hard drive, and then the CD drive (respectively).

So i'm stuck, not sure where to proceed since it's obviously not the hard drive itself, I use it on my xbox all the time. What next?

Recently I took a look at my girlfriend's PC as explorer crashed each time it was booted, even safe mode wouldn't work. I opted to re-install the OS from scratch. The only problem I had was that she needed some files backing up, so I had no option but to plug her HDD into a spare SATA bay I have in my own PC (80GB of data needed to be saved, I don't have an external HDD that big).

Anyhow, I backed up the files to a HDD I have in my computer and then re-installed Windows on her HDD in my own PC. I then put her data back onto the HDD. Everything worked fine in my PC, I was able to boot into Windows XP no problem. Please note I didn't install any drivers apart from any defaults the XP install detected and installed.

After putting the HDD (with the assumedly fixed XP install and recovered data) back into her PC I cannot get it to boot at all. I get the following error message:

Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device and press a key

I have tried the following and keep getting the same message:

1. Checked BIOS and set it to default.
2. Removed the system battery to hard reset BIOS.
3. Performed a full repair on the XP install using an XP CD.
4. Executed several commands in recovery console: bootcfg, fixboot and fixmbr.
5. Used chkdsk, HDD appears to be fine.
6. Unlpugged everything, checked connections, etc.

I would boot with the WinXP cd in her pc with her hard drive. Start WinXP setup, delete the partition on the hard drive and continue installing windows. (make sure you still have that backup!)
It is not a good idea to install Windows on a hard drive meant for another pc. Unless the computers are identical (especially the motherboards) otherwise there is a good chance you will have driver and performance issues.

Hi there,

Hmmmmm.....it's possible that you might have a faulty hard drive. Do this, go to a working computer an download a good hard drive diagnostics utility called "SEATOOLS". Here is the link to the Seatools program: SeaTools | Seagate

Download Seatools and put the program onto a bootable device (e.g. CD). Boot the computer to the Seatools CD, follow the on-screen instructions, and scan your computer hard drive for any errors. Make sure you use both short and extended test.

Hope everything works out well and please provide an update when you can, thank you.

I have two issues, which I think are related. In the Device Manager, it shows under USB Controllers "Unknown device". "Windows has stopped this device because it has reported problems. (Code 43)"

I tried updating the driver, but the driver was correct.

I tried disabling the device.

I uninstalled the device. Windows reinstalled it at next boot, but the problem reappeared.

There is no Imaging Devices in the Device Manager.

At the same time, my webcam failed to open. Message "Webcamera initialization failed."

I downloaded the correct webcam program from Toshiba, installed it, but same result.

This all started when I uninstalled and reinstalled Skype. I have tried uninstalling it again, but still no webcam.

The webcam is enabled in the BIOS.

I really do not want to reinstall Windows.

All help appreciated.

First let me tell you about my system.   This is an Inspiron
E1705/9400 laptop with the T7400 Core 2 Duo processor running at 2.16
GHZ.   It has 2 GB of RAM and a brand new 500GB Hitachi Travelstar hard
drive (7200 RPM).   It also has the GeForce Go 7900 GS video card.   
It previously had Windows XP Professional (32 bit) and worked fine.  
But, I have three computers in my home and home office and would like
them all to work better together on my wired home network, so I am
upgrading all three to Windows 7.   My two desktops (one is Dimension
XPS 420 and the other is Dimension XPS 430) seem like they will be no
problem to upgrade to Windows 7.   But, this laptop was not listed on
Dell's Windows 7 Compatibility List.   However, the Windows 7 Upgrade
Advisor that I downloaded and ran seemed to say that it was OK to do a
clean install of 32 bit Windows 7 and it only had a few minor concerns,
where it said to check for updated drivers from the manufacturer.   The
laptop originally came with a 100GB hard drive.   For my use, that is
getting very small, so I decided to get the same exact 7200 RPM drive
in the 500 GB size.   This will allow me to do a clean install of the
32 bit Windows 7 OS on the new hard drive and not have to wipe the old
drive to do it.   I can just hold onto the old HD and stick it back in

Hello, Ive recently been getting this message and I cant seem to solve it.
I read a few topics and solutions, but I can't seem to grasp it. I am rather greatly unfamiliar with pc tech know how.
I tried putting the OS disk and restart, but I get the same error, and I dont know how to reinstall the OS. I can manage to get to the BIOS, if thats what its called, but Im not sure what to do from there. I tried setting priority to CD Rom but still, same error.

Im considering visiting the tech shop that built me the PC but if I can fix this at home I would give it a shot.

Im running Windows 7 Home premium 64bit.

When left alone..."Reboot and select proper boot device or Insert boot media in selected boot device and press a key"

I have a new(ish) cpu that I bought last Christmas, it works great and it has not crashed on me whenever I am using it. However, when I leave it on overnight (usually when it is downloading something big), when I wake up in the morning I am greeted with a black screen with the words:

"Reboot and select proper boot device or Insert boot media in selected boot device and press a key"

When this happens I simply press the power button a few seconds to turn it off, then turn it on again and it boots normally. (pressing a key only results in the message being repeated)

What infuriates me is that it only ever happens when I leave it on overnight so I don't know when and how exactly it occurs but it almost always does. Like I said earler, it never does this when I am using it as it works fine otherwise. It just won't stay on overnight when I need it to. Any thoughts on how to resolve this?

Is it possible to transfer boot files from one hard drive to another?

I have 2 hard drives (S-ATA): one is a 320GB, and the other is a 1TB.

I have Windows XP installed on the 1TB drive, yet I notice that these bootup folders and files are on the 320GB drive:

[System Volume Information]

Therefore, when I wanted to use this 320GB drive for another computer (that had a defective hard drive), I backed up all the important data from the drive, then I took the drive out, then booted the computer back up, just to make sure it still works. That's when I got that "Reboot and select proper boot device" error.

I guess this is because the boot files got created on the 320GB drive (which is NOT the drive that Windows XP is installed onto) instead of the 1TB drive.

So, what I'd like to know is if I can somehow just copy the folders and files (including hidden ones) and then be able to boot from the 1TB drive. I doubt it would be that simple, but there MUST be a way to transfer the boot information to the 1TB drive.

Does it have something to do with BootMBR, or Windows Recovery, or something like that?

I don't want to change anything until I get some opinions from others.

Hi! I just burned a copy of the Windows 8 Developer Preview onto a DVD. I have created a partition for the new OS (because I don't want to install over Windows 7).

When Windows 7 is running and I pop in the DVD, the computer directly recognizes it as a runnable program. I'm also able to install Windows 8 when Windows is running.

But because I want to install it to another partition I need to boot from the DVD. But I can't. First it just ignores the DVD, and boots right into Windows 7. So I tried to force boot via BIOS. Then it just said "Reboot and select proper boot device or insert boot media in selected". Can someone please help me?

I have recently bought a new hard drive and now I want to remove the old one and just use the new one.
When I remove the old one, I try to start up the PC with the new only, but it stucks at booting, it says "select proper boot device..."

The old one was a 300 GB, WD SATA 2. And the new one is a Seagate SATA 3 1TB. I want to use the old one with an older PC for somebody else, but if I remove it I can't get into Windows.

Windows 7 is installed in the new HDD. The old one is empty, but I see there is still some "System Reserved" partition there which is being used. Here is how disk management looks like: http://i.imgur.com/Gsbh3dF.png

Here is my question: I have Vista 32-bit operating system with an original-equipment ViXS PureTV-U 48B0 (NTSC/ATSC Combo) TV Tuner. The computer itself is a m9100z HP Pavilion. Every time I restart my computer, the TV Tuner card will toggle whether or not it is visible/installed/whatever in the device manager. If the card is working, once I restart, it will not work or appear in the device manager, and vice versa. The only way I have found to fix it is to restart again.

Any suggestions?

im thinking it ignores the disc because the order you have for booting 7 is from hardrive first, if you press f1 or f8 or one of the f buttons at the black screen before 7 loads you will get the order of which to boot from first ,select disc and it should load the install screens .
