Error loading operating system Dell Optiplex 740 used in Raw Thrills Arcade

Q: Error loading operating system Dell Optiplex 740 used in Raw Thrills Arcade

I am currently upgrading a Raw Thrills Fast and Furious Drift arcade from a microtel pc to a Dell optiplex 740. I also upgraded the video card. I was able to run the three disks for the 3.04 version of the game. Everything seemed to going fine until I started the machine. I had also changed power settings in BIOS to power on after AC loss. The Dell powers on and enters an error screen, "The memory has changed" with options for continue and setup. When I continue it goes to another error, " Error loading operating system". I noticed that when the 1st game disk was run it said erasing hard drive. I figured that to be standard. But now I'm at a dead end on what to do next. Did running the disks erase the windows 10? Am I doing something wrong? And what would be the fix for this?
Thank you, Rooster

Preferred Solution: Error loading operating system Dell Optiplex 740 used in Raw Thrills Arcade

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.)

Most likely your game disc was infected with a virus -- game installers SHOULD NOT format the hard drive.
Run an extended diagnostic on the system (F12 at powerup). If the hardware passes, reload the OS.

Hey all! I am pretty new to this kind of Win7 issues, so I hope some of you will be able to help. Story goes...

After few hours of gaming the computer died. (It happened right after switching keyboards.) Now, on every setup BIOS(?) comes up with list of options (F2 enter BIOS, F11 boot options, F6 Flash etc.). After that a black screen with error message comes up: Missing Operating System.

I tried rebooting from USB (since I have no disk-drive) and I keep on getting the answer: Error Loading Operating System.

Any ideas?


A:Missing Operating System/Error Loading Operating System

All unlikely, but possible - (a) your HDD died. (b) your bios became corrupted (c) your HDD boot sector became corrupted (d) your HDD partition is corrupted.

Does the drive spin up when you switch on (feel it)?
Check the bios to see if the HDD is reported correctly and is at the top of the boot order.
Find a bootable CD - an OS installer, or create Easeus partition manager bootable CD http://www.partition-tool.com/personal.htm and boot from it. What does the HDD look like with Easueus?

Do you have the restore disks for your system?
Or, do you have an XP installation CD for your system?

If not, then I'd first suggest trying a bootable hard drive diagnostic from the manufacturer of your hard drive.

There is a problem with my old PC (Windows 7 x32, Intel duo core processor, 2.5 GB RAM) which was custom or assembled, it says 'Error loading operating system' and I have been trying to fix it for hours..
Earlier when this happened (A lot of times), I fixed it from the Repair option when I press F8 contineously, but when i keep on pressing it, nothing happens (System Repair Blackscreen does not come).
It happened when I pressed the restart button in my CPU when my PC was stuck for a long time, instead of waiting and manually restarting.
The biggest problem is that I LOST my Windows 7 CD. All I have now is just a USB with backup files.
When I put on the USB while booting, it says 'BOOTMGR is missing, Press Ctrl+Alt+Del to restart' but it shows the same thing when I restart.
When I pressed F10, It showed the Boot Option Menu, it had 3 options:
• SATA: Optiarc DVD RW AD-72203
• Realtek Boot Agent
• MBIC SS MMoser Baee Disk PMAP (That one is my USB)
These 3 didn't work either....
So, Please help me to find a way to fix it.
Ask me if you want any more information.

Thanks now its solved

This morning, I went to turn on my PC and received a black screen with the following message - Error loading operating system. I have Windows XP Professional.

Yesterday, I was having trouble w/IE 6.0 - it kept radomly closing on me - so I thought perhaps I had a virus. I installed the latest MS updates and then ran my virus scan, Etrust antivirus overnight. When I checked out the PC this morning it had rebooted and was showing a black screen w/the above-referenced error message.

I do not have an Automated System Recovery disk for this PC, and, even worse, I do not have my files, etc., backed up (yes, I'm an idiot). Otherwise I probably would have simply reinstalled Windows

I ran a diagnostic called BootMaster Partition Recovery (http://bootmaster.filerecovery.biz/index.html) and it told me that an NTFS volume on drive 1 appears to be in an unstable condition (called it a dirty volume) and BootMaster couldn't repair it, and that I should call Microsoft, which I'm not really inclined to do (I'm happy to pay for tech support, but I'm not convinced calling Microsoft is the most expeditious way to go).

So, any thoughts out there on whether or not there is any chance I can save my data?

Many, many thanks.

I'm having the same problem on my computer. I built mine on my own. It will start to boot up, finish the PCI Devices Listing and then display "Error Loading OS" right after it says it verifying DMI Pool Data... I accessed the bios and my HD is detected. I have a 200Gb internal hard drive as a slave drive to it and I am curious as to whether I could switch the cables between the HDs and get it to boot off the 200Gb and install XP on it, then pull the data off of the old one (original boot drive) that is now connected as the slave drive.

Hanging at the DMI Pool is totally different. can of worms. I suggest starting your own thread on the subject

Ok, its been few days now since i made attempt to try to reinstall Windows XP on an olfer Dell Dimesion 2400. I should also note that i do not have any of the original cd's that came with.
So, since the machine was not responding due to malware and viruses, I figured reinstalling the OS will be the only way out….
Well, halfway during windows xp installation process, there was some questions on blue screen asking for formatting the hard drive and patricians and other questionnaires – well, since I wanted the whole thing to be wiped out (nothing of value was there anyway) I let it delete all.
Somewhere along the way, machines stalled and returns “error loading operating system”
Tried numerous scenarios to try to resolve the issue
1. Started without CD – same issue
2. With CD……says strike any key – once I hit any key – same error come back on black screen.
3. BIOS checked boot sequence and change to CD first – no help either.

At this point, I ‘m just tired of scratching my head and will greatly appreciate some advice or the if I should consider burying this thing –

I don’t know if this was clear enough, but my main concern is to regain access to the machine so I can install windows XP professional – please note, the previous windows version on the machine was Home Edition if that will help.
Again, Error Loading Operating System” on black screen has been my nightmare during past few days.

I have this same problem. I set partitions for installing XP the setup copies the files, restarts and says error loading operating system.

I have tried:
Taking out 1 of 2 RAM sticks
Updating BIOS
Swapping CD ROM drives for install
Used a different XP installation disc

The BIOS detects both HD and CD-R
There is only 1 IDE port on the MOBO so its running the CD ROM and Hard Drive through one cable, its awkwardly wired but iv done this before and it works so im presuming this isnt the problem. Jumpers are set correctly for master and slave. The ribbon cable end is going to the Hard Drive MASTER and the middle end of the ribbon cable is going to the SLAVE CD ROM.

The PSU is 400W running an Athalon X2 4200+, 2 gigs of ram, 160gb hd, 1 dvd rw, an ATI x700
Dont spose this is related in any way.

No idea what else to try, has anyone got any suggestions?

A:Another Error Loading Operating System

Hi, I've tried searching the forum, but nobody seems to have had the exact same problem as me.

I've had the same computer for 2 years now, one which I built myself, and until a couple of days ago, it's been fine.

However, it was starting to get a little slow, and so I looked on the internet for ideas on how to fix it.

I can't say for sure what caused the problem, because I did a few things. However, most was removing itunes from startup and the like (obviously I didn't stop any services that I shouldn't have) and the windows sidebar. The only thing that I hadn't done before was a service called error checking, and I also selected the scan and perform recovery of bad sectors bit.

Anyway, when I tried to boot again I got the message "error loading operating sytem."

I have tried changing boot settings in the BIOS, switching the hard drive that is used to load in case it was using the wrong one.

I saw a lot of people had success with fixboot and fixmbr with the vista disk. I have one, but can't load from it. I put it in and select to boot, get the press any key message, loading windows components, the bar loading, and then just a blank screen. I've left it for hours and still nothing happens.

This is driving me crazy, does anyone please have any idea what I could try?

A:Error Loading Operating System

Try booting in safe mode F8 during system post logo. If Windows loads go to start type in CMD in the command prompt

type in y for yes reboot.

It is odd that the Windows disk does not work. Could be scratches on the disk. Is the disk a genuine copy?

I was attempting to load XP on a separate drive from my Vista machine. Booted in the XP CD, formatted and began the installation. After the setup files were copied to the other drive, the computer rebooted to finish the installation. Upon reboot, I got "Error loading operating system".

Reading further, I see that the mbr, boot sector and boot files were overwritten on my computer. I booted from my Vista DVD, navigated to the Boot directory, and issued "Bootsect.exe /NT60 All" at command prompt. Says it was successful. I reboot and still get the same error.

I also tried the automatic repair option. It didn't find any problems and didn't fix the error.

Booted again to command prompt from the Vista DVD. This time tried:
bootrec /FixMbr
bootrec /FixBoot
bootrec /RebuildBcd

When I issued last command, it said it was successful but # Windows installations found was 0.

Also did a chkdsk on my hard drive and came back clean. All files and directories are still present as well.

Rebooted and still getting the same error. What do I need to do?

If your xp installation went through smoothly without skipping any of its files then i'd suggest you to download EasyBCD. This one will allow you to modify your mbr at ease, it works fine in vista but in xp it requires dot net framework 2.

Hi all, I have searched several tech forums for answers, found some, but none have fixed my issue.

When I start my computer, I get the black screen with one line across the top saying, "error loading operating system".

I thought by putting the Windows disk in, I could run a recovery. The only option it will allow me to select is to reformat the harddrive. I would like to figure out why I get this message and how to fix it.

If it can't be fixed...I have also tried to make this harddrive a slave to another one. I am able to see the new drive in my computer, but if you click on that drive, it says drive is not formatted. Is there any way I can get the data off of this disk?

Hello all - happy Monday (or not). I have received the dreaded shut down of all my programs and the white lettering with black background, i tried to follow instructions provided on this topic previously but only got so far as i believe i need someone to look at my mbr. I have created a cd that i can boot from that allowed me to create said mbr on the usb key via xPUD but honestly am a newbie when it comes to all things technical. I did try to use the F8 key after BIOS (Dell Inspiron 530 Bios 1.0.13) but no avail just clicked - i am able to get to xPUD via the boot disk but not sure where to go from there - if you need a copy of the mbr this can be provided. Any help is appreciated would really like to fix this. It is our hub for our family network and obviously is a drag. The wireless is still kicking and all can still use the network so no issue there.

the first error that started all this was an invalid disk partition or something like that - that is what lead me down this road and eventually to you!

thank you all for your assistance!

I am using windows 7 on my computer and recently I figured that my computer started freezing a lot so I decided to install a fresh copy of windows. I did the same and scanned my whole computer and found no viruses either, the freezing problem was still not fixed. I searched up some but found no good solution. Then somehow the condition started getting worse, my computer stopped booting and it started restarting itself at the win7 startup animation. And then even worse.. now it only shows a black screen after turning it on and then shows the error "error loading operating system"after a few minutes. I tried many things I found online but nothing worked since I can't even get Into my windows for now. Safe mode isn't working either, I have no idea what to do now, please help me with this error. Or could it be a hardware problem too?
Please remember I only have a bootable windows 7 USB with me, no cd/dvd at this moment if the fix requires a copy of windows.

I just got my new windows 2000 laptop at work. I was poking around in it to see what new stuff was on it, and decided to backup the hard drive...
Here's my problem.
1) I don't know what the program was that I was using. It said Do you want to take a snapshot of your hard drive?
I clicked yes.
2) It then said that it would reboot in DOS and continue taking a snapshot of my harddrive, and that it may take 2 hours to complete.
Again, I clicked OK.
3) It shut down and tried to reboot (in DOS, I guess) but I got an "error loading operating system" instead.
4) I don't have an ERD made yet.
5) I tried pressing f8 to go to the last known good config, but (of course) that only works with an OS.

Welcome aboard, I see this is your first posting.

It sounds like you are able to recover and access Windows 2000, but cannot get the backup to work. Is that your problem? It sounds like a drive image utility which can be used for backup was installed but it is broken or damaged. Windows 2000 does not come with one. The two most popular ones are Norton Ghost and PowerQuest DriveImage. To fix the problem you would need to reinstall the utility that was installed.

When I turned it back on it gave me the error message, but when I hit F12 during start up and select "primary master" startup it wil work perfectly.

Hi everyone!

Well as the title says, I got that message when booting. Actually it is a long story before i got that message so i'll try to sum it up. So, what i've done and what happened are as follows:

27 October 2012: I built my PC from a scratch.

three weeks ago: I began suspecting HDD failure because it is not detected in the bios frequently, failed short dst and long generic test in seatools for windows and began to make weird sounds (kind of a scratching or grinding noise, but I can't really describe it) only when booting or extracting .rar files.

two weeks ago : the problem with the bios was gone. But the sound retains.

1.5 - 1 week ago : the PC loads gadgets and some programs (that launch on startup ex. drivers, antivirus) a bit slower. I suspect the HDD is causing this because the other components are fine and my PC could play games in full HD. Windows explorer also crashes sometimes, and minecraft too.

Just YESTERDAY : I've had enough with constant explorer crashing and slow system, so I decided to open my HDD to check for hardware problems (It's a stupid move, i know) but I failed because after i opened the screw and tried to open the cover I can't because the cover is shut tight and prying it open wont work. Then i just put the HDD back together with the PC and booted, then magically an error status 0xc000000f appeared on my screen. I searched forums and run repairs from my installation disk but my OS is not listed. So i went on to the commant prompt and use... Read more

I seem to have done the unthinkable and stupidly tryed to install a second Windows XP after having Windows Vista and Windows XP installed. As soon as my computer restarted after copying the XP setup files, I got confronted by "Error Loading Operating System". I've been searching around the net for about 2 hours now and it led me to a few different methods to try, which i did, but I still can't figure it out.

What I've done so far is put my Vista disc in and hit repair, then tryed the first option to fix the startup, which didn't work. I then went into the CMD option and tryed to fix my boot file. I understand this is done through bcdedit. First I executed "bootsect -NT60 All" and it reset the master boot to be handled by bootmgr but nothing changed except a new symptom appeared. When I restarted. instead of telling me to press a key if I wanted to launch into the DVD, it came up with something to the effect of "CDROM: BOOTMGR MISSING" (I can't remember exactly). Then after restarting it just asked normally if I would like to launch into the DVD, which I did again and this time I went to BCDEdit and deleted the original Windows XP boot details. Now I'm left with just the Windows Vista boot details but the same problem still arises.

When I view the details on Windows Boot Manager through BCDEdit it says that the device is on partition C: (the partition with XP) and the Windows Boot Loader details says that its device and osdevice is on E: (th... Read more

So I was attempting to fix my laptop hard drive, so I connected it to my computer using an external enclosure. My laptop was having problems finishing a Windows XP installation, so I decided to try to install XP using my other computer. I booted my Windows Vista based computer to the Windows XP installation cd. I selected the laptop hard drive to install Windows XP on to. Once it finished formatting the partition, I received an error stating that the hard drive was unable to complete the partition process. I just assumed that the hard drive was dead. Therefore, I unplugged the laptop hard drive from my PC, and attempted to boot to Vista, the only OS on my PC. This is when I got the "Error loading operating system" error. I tried researching this problem, and I found this article:


I was following the steps using the command prompt on the Windows Vista installation cd, in the repair section. Once I tried to enter "C:\boot\Bootsect.exe /NT60 All" which is the first step in the directions, it said that "C:\boot\Bootsect.exe was not recognized as an internal or external command"

I really think this is the path I need to follow, as I believe that Windows XP may have messed with the Windows Vista Boot Manager. If anyone has any ideas, please post. Thanks.

It looks like you may have deleted your boot information for Vista. You may have selected the secondary hard drive to install XP to, but it will still try to write info to your primary hard drive.

I'm not sure of a quick fix, unless you can do some type of re-install of Vista, but choose to keep your current system and just re-install windows vista.

Hello elimelim and welcome to TSF!

Have you tried unplugging your SATA/EIDE cable from your harddrive or maybe changing the cable? If this doesn't work, do you have another computer and plug in the harddrive and see if will detect it? If not, time for you to upgrade then.

I recently downloaded a media file, im not sure if its corrupt or not but i have reason to believe it is.
The colours went dodgy (only 4 colour bits and 600x800 sommin resolution and it wont allow me to change anything).
Then i shutdown windows and tried to restart, i out in my recovery diskette but that made it worse. now i started the computer, its about to load up but a message says "error loading operating system".
I tried using a AV disk using BIOS setup and tried reinstalling windows, but it doesnt help.

Any ideas to fix this?

A:Error loading operating system

Assuming you have Windows XP from your 4bit colour setting. Sounds like it might be a display driver problem. If you completely re-intalled Windows, you need to install motherboard drivers and video drivers if they are seperate.

If you need more help, please try to post more details as to what happened and what you did exactly.

You could connect it to another PC as a slave drive, get all your important data from it and then reformat it and reinstall your OS.
Before you reinstall the OS, download to disc the Disc Utility for your particular Hard Drive, ie; Maxtor/Seagate, WD and run a
disc check to make sure your drive is still in good shape and if shows the disc is good, use the same utility to ZERO out the drive,
then format and reinstall

Hey basicly i have a slight problem and i am running out of ways to resolve it.

I have a custom built computer and every time i go to turn it on i grnt an error just befor its about to start loading windows XP

" Error Loading Operating System "

Both hard drives and Disk drives are recognized in the bios setup.

I have tried booting from CD with no responce even tried UBCD and Linux to see if they would boot

Failing that i checked weather the disks were ok so i poped into my other computer they seemed to load up fine.

its like the system wont let you do anything at all.

Any help much appreciated

A:Error Loading Operating System

Go into the Bios. Try changing the Boot priority. This is not the same as 1st boot, 2nd boot etc.

Hello I have a Sony VAIO VGN-A250 notebook running Win/XP Home. When I boot it up it goes to "Error loading operating system" I know the HD is detected because I checked the BIOS and it lists it as the 1 boot device.

If I use the recovery disks will I lose all the data on the HD? Will I have to reinstall Windows?

I don't have the recovery disks that came with the notebook but have the Win/XP disk for my Dell desktop, can I use that disk?

If you use your laptop recovery CD's you will lose the lot in most cases as it reinstalls Windows and leaves the laptop as it left the factory. But you don't have them?

If you tried to use your Dell CD it will fail as the Dell CD will have all the Dell specific device drivers, and will likely be BIOS code locked to the Dell, so it will either refuse to even install (likely) or if it did install the laptop would be borked as all device drivers would have the wrong code force fed and fail. All data would also be lost.

About now you should be considering dropping the HDD out of the laptop and attaching to an XP desktop via an adapter (2.5 to 3.5 IDE) or in an external USB case, to recover your data.

Data that only exists only on a HDD is data that you don't care about losing, as file systems or hard drives can corrupt or fail at any time with no warning. And they do.

You may have to get your Sony CD's or buy another copy of XP.

My computer appears to be running perfectly normal apart from the fact
that whenever I try to restore a partition, clone a drive or attempt
do a clean install, it will not boot and I get the message saying, error
loading operating system. It can't be the hard drives because it
happens even with my brand new hard drive. If the drive I'm using
boots perfectly and I clone it to another drive, surely they are both
exactly the same. So why will the newly cloned drive not boot?

A:Error Loading Operating System

Because the new drive isn't exactly the same as the old one (even "identical" drives aren't the same).
But, I don't think that this relates directly to your problem (since a clean install wouldn't suffer from this issue).

Could you describe what you're trying to do in a bit more detail so we can start troubleshooting it at the appropriate level?

I have a computer that got struck by lightning which fried the motherboard. In the process of waiting for a replacement motherboard I put the hard drive in another computer and did a window repair on it to get it running. I put in the new motherboard and needless to say it didn't work and all I had was a blinking underscore.

I tried a repair on the hard drive again this time in the same computer, nothing, I changed every part in the computer accept the motherboard still nothing, i've run chkdsk so many times its rediculous. I've written a new boot sector, and a new MBR. After doing all of this I get Error loading operating system when I try to boot the computer. I upgraded the bios still nothing. I can't lose whats on this hard drive no questions about it. I do have a backup of the hard drive which also doesn't work in the computer. When I put either the backup of the real on in the computer that I did the repair on it boots fine.

Any help would be appreciated

A:Error loading operating system

the easiest thing to do would be to install your questionable hard drive in a working computer in slave mode, assuming both are the same file format, or at least the removed drive isnt ntsf and the surrogate drive isnt fat32...
on the working computer, unplug the rom and use the power and ribbon cables for your hard drive, you probably will need to pin the hard drive in the slave position.
once that is achieved, copy your info via windows explorer.

on the bad computer, the motherboards would need to be the exact same model for the installation to work without loading the chipset drivers for the new mainboard... http://www.geocities.com/kilian00720...p/sysprep.html

and a power surge will normally take out the power supply.

Hi there,
I own a DELL Dimension 4600C, and I had a trouble with it last week. I got the message for "Unmountable Boot". I misplaced my original Windows XP Pro CD, so I used my friend's bootable XP CD, and try to check disk. I followed instructions on the Microsoft website, nothing worked until I made bootable floppies and tried to repair the system. It wouldn't complete the repairing and always went back to the blue screen with the unmountable boot error.

I decided to reformat, so I deleted the partition and tried to install the new windows. It took way too long to delete the partition, and at the end I received a message indicating can't be completed ( I can't recall the reason).After that, I keep getting black screen with error of loading operating system.

Any guidence or help to resolve this problem will be really appreicated.

Welcome to TSF,

Download and run the drive manufacturer’s utilities If the drive passes diagnostics, use the utility to wipe or zero the drive and try the install again. Sounds like remnants of the old install are preventing the new install

I recently contracted a nasty virus on my office computer (via trojandropper). That computer is running on Win7. The virus messed with the MBR. In my effort to fix it, I connected the drive to my home computer (running XP Home) and ran an antivirus scan, which found plenty of infection but didn't solve the problem and also ran chkdsk, fixboot, fixmbr and bootcfg /repair.

Now my home computer is also broken. It won't boot to Windows. I get the message "error loading operating system". The drive is found in BIOS. The partition is found in chkdsk and bootcfg /repair which reports that it is repaired.

The drive looks fine if I slave it to another computer running XP. I also ran AVG and EASUS Partition Recovery 5.0.1 on the drive while it was slaved. Still no bueno.

I noticed that in diskpart the drive (a 320GB Seagate Barracuda) has 65MB of unformatted space. I tried to clear out that space by partitioning it, formatting it and then deleting the partition. It would not allow me to partition 1MB of the free space.

Finally, I tried Repair Install of XP, which recognized the old installation and completed fine, but the computer still won't boot to Windows and gives me the same error message.

Please help. I do not want to wipe the drive and start over.
