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?

I have made a rather large mistake and would like to know if it can be fixed.
I installed a new hard drive, and tried to copy my old partition with XP in it across to a new partition on my new HDD with Partition Magic. While it did that it also deleted my old partition with the original copy of XP.
I now can not boot from the new HDD - although a boot record is found on my new HDD - windows will not boot - giving me the error loading operating system.

Is there a way of getting on to the DOS prompt and while there - telling the system to boot from the record it finds?

I really need help here. I am not very computer savvy so I'm completely lost at this point. When I turn my computer (Dell Dimension 8400 running Windows Media XP) on it looks as though it's going to start but then the dreaded blank screen stating "ERROR LOADING OPERATING SYSTEM". I read a bit in the forum that I may need a recovery disc, which never came with my Dell computer. I called Dell and they will not send me a recovery disc because I'm out of warranty, big surprise. Is there any way I can download it from the internet or is there something else I can do. I unfortunately have no back up CD. My priority is to keep all my programs, internet bookmarks and documents. If anyone has any ideas I would love to hear them. Remember I?m not that computer savvy so I?ll need very detailed instructions on what to do. Thanks to all.

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.

A:Error Loading Operating System

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.

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.

A:Error loading operating system

ok, the fact that a clean install didn't fix it pretty much confirms that it is a hardware issue, have you tried startup repair yet? hat might reveal what is stopping you getting into the PC and at least allow you to get in and find out what is wrong.

I was trying to fix my dad's computer for him after he got a virus. He tried a couple of different virus removal programs and none of them were successful at removing it so I told him I would format his hard drive and reinstall Windows XP on his PC. I've done this many times before on my own machine but it seems like with more recent computers they (probably in an effort to make them more user friendly) they've avtually made it harder to do formatting etc in DOS.

I have a Windows XP disc that came with the computer. It doesn't appear to be a restore disc but the actual operating system itself. I tried just booting the computer off the disc and finally was able to get in to where I completely reformatted the portion of the hard drive that Widows was installed on. I figured when I rebooted the machine it would just load windows off of the CD Rom and everything would be back to normal but now I am just getting an "error loading operating system" on the black DOS boot up screen and I can't do anything from there except just reboot the computer. I've tried everything including going into the system setup and making sure the hard drive is recognized and runing a diagnostic on the harddrive and everything checks out OK. I've even swapped out the CD Rom just to make sure that wasn't the problem. The only thing I can think of, if the hard drive was evidently partitioned (I'm not too familiar with partitioning) and I removed the partitions... Read more

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.

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

Hi everyone. I really don't have a clue about what has happened to my pc. I shut it down fine last night - no problems. I haven't installed anything new either. This morning i turn it on again only to see a black screen with: ERROR LOADING OPERATING SYSTEM.

I tried putting the pc into safe mode but no luck. I tried F1-12, DEL,ESC etc on boot up but it just refuses to go into safe mode. The error message remains and doesn't budge. All i hear is a beeping everytime i'm pressing one of the buttons mentioned above. I honestly don't have a clue where to start with this. I'm really worried about losing my files as i only have half of them backed up and they are really important. Is there any way i can fix this problem and retain my files at the same time?

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

Hi megatron, and "Welcome to the Seven Forums." . . .

Now to the problem at hand. First we need to know what operating system you are using. Microsoft Office 2007 is not an operating system. To find out what OS you are using "press and hold the down the Windows Key then push the Pause Key." Doing this will bring up what is known at the "View basic information about your computer."

From that screen you will see the basic information about your operating system and the computer itself. Now type in that information so that we who wish to help can see what operating system, and computer you are using. With this information we can at least start to give you some ideas as to the problem. . .

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?

The best solution would be actually loading the operating system, but if that's not possible then the next port of call would be somehow backing up files (read something about hooking it up as a slave to another machine?)

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.

I have been unable to load Windows XP on the new hardrive (only drive in the system). Initially, everything apperared to be working. The expected screens appeared during setup and got down to formatting the hardrive. Because this process is lengthy, I left the computer and on returnng the computer had shut down. Any attempt to restart the process of loading Windows XP gives the above error message. Disconnecting the hardrive allows the seup process to continue until setup is unable to detect a hardrive, then it stops. How do I get around this error, which I suspect has something to do with the hardrive? Any help is appreciated!

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.

I am a newbie here so bare with me. I attempted a new install of Xp and it failed and I have no idea what to try next. My last new install of Xp was about 3 yrs ago with this same equipment so it did all work together no problem.

I placed the Xp cd into the dvd RW and rebooted and the setup began. I cleared the partition first. Step two was to create the partition and it went ok. Then step three was to install. It went along fine and then it said something like it was not able to install it completely and something to do with partitions. I clicked it back to look at step one about the partitions and then it asked me if I wanted to do a quick install or regular install and then I tried the quick install to see if that would work better. After that it didn't work and since then all I get when I reboot is "error loading operating system".

I have tried to reboot from the disk but it will not. I have set the bios to the defaults with no luck. I do not have a floppy drive anymore. I even swapped out the dvd RW to the old cd player to see if it was the dvd that wasn't working. So that hardware is not the culprit. Same error message. I checked the cables and etc and everything looks normal. I do get a good posting beep.

My machine is an older Dell Demension 650, PIII, 650MHz, 256 cache, 256 memory which I upgraded with another stick. I did flash the bios several years ago to upgrade to win2000. I did learn that they didn't write the driver that well since I had t... Read more

update, well I stepped away from the machine and tried more variations on the same theme. It helped. I had changed the boot order several times with the hard drive being either the first or the second to other drives. This time I put it last. For some reason it liked this. I think that bios I flashed from Dell maybe the culprit. I was able to get it to boot from a cd. I placed the Xp cd in and it began the setup process only so far but then it stopped and asked for the Xp cd again and hit enter and I did this, nothing but requested cd again. So instead of putting in Xp, I tried an old Win98 cd and then it liked that for awhile and then it asked me for the Xp again and I put it in and the formating is going right now. When set up started it asked me if I wanted to install or fix an installation. I had tried the fix the installation but it gave me this prompt in dos c:\> but I wasn't able to switch it to just c: to try fdisk and start over that way. I am thinking that this maybe related to the file systems and Xp is having a hard time being read by old bios file system that was poorly written in the first place. I am hoping the Win98 was able to partition the drive in the old language and Xp can now install into it.

hello i need some help with this one, i guess i should explain this from the start, i installed windows 7 64bit ultimate (7600) a few weeks back, but just a few days ago i decided to install windows xp home sp3 on my back up drive for other reasons, qoute me instension was not to have a dual boot partitions, i unpluged the sata cable on first hard drive that has windows 7 installed, and just booted of my second drive with xp only, now today i dicdided to reformat the back up drive with xp cd, i shut the computer off plugged in sata 1 cable back to first hard drive, went into bios set sata 1 option to auto detect then rebooted pc thinking it would load into windows 7 but i get this (error loading operating system) with a black screen, so i thought maybe some how my hardrive got currepted so i attempt a few things, i reinstalled windows 7 without formating, reason why cause i dont want to go trough all the hassle to reinstall all windows and all my games apps etc, so after a reinstalled i thought everything was fine, i restarted computer i got the same error, rebooted 6 times with no luck, the only way i can load into windows is by putting the windows 7 disc back in

Hello everyone!

I had Windows Vista on a WD Velociraptor (74GB). Then I got a WD Velociraptor (300GB) and put Windows 7 on it. So, two Operating Systems on two separate hard drives. Normally, after my BIOS screen, a menu loads asking if I want to boot Windows 7 or Windows Vista. Vista was the C drive, 7 was the F drive. It worked gloriously for several months. But now the pain has begun. The sound on my computer was very quiet one day. Everything seemed set correctly, so I decided to try a restart. During the restart, when it reached the black Windows 7 screen, it seemed to freeze. I restarted the computer again. After the BIOS screen, where I would normally be asked what OS I want, it instead says "Error Loading Operating System". And now that is the message I get every time I try to restart my computer.

-Both hard drives are listed by my BIOS.

-If I disconnect or disable only the 74GB drive, I get "Error Loading Operating System"

-If I disconnect or disable only the 300GB drive, I get "Error Loading Operating System"

-I have not been able to locate my Windows Vista CD yet (although I probably could if it were the likely solution)

-I located my Windows 7 CD. I booted from the disc with only the 300GB drive and CD drive enabled in the BIOS. I went to the "Repair your computer". In the System Recover Options screen, there are no operating systems listed. I don't have a system image to restore from, so I sele... Read more

Ok. Not very happy right now.

When I boot up my pc, it immeadiatly (or almost) jumps to black screen stating "Error loading operating system" nothing more, nothing less. Right before I got this message, I had BSOD "Driver IRQL not less or equal". The only changes to my system were opening my external hard drive to clean it. I am looking for a remedy to make this drive, os and all, useable again. Please dont repost saying reformat. That wont be of much help. Thanks in advance.

Is this a new build, old HD w/fresh install, previously working computer now won't start? Is there important data on the HD? Where to start is in the bios, check to make sure the HD is being found and ID'd by the computer. Check the HD jumper and verify it is set to master. Since it boots off the CD and not off the HD and you can access it, download the diagnostic utility for your brand HD and run it. It's possible corrupt files on the HD are preventing the boot, but test the HD first for mechanical errors. Mike

I had been using my computer and I got a blue screen. I didn't think much of it, but when I tried to restart, the BIOS stopped with a message "Error loading operating system" and understandably won't go past that. I have a multiboot linux live usb with puppy and ubuntu so I can access my computer but in puppy my hard drive isn't showing up (haven't checked in ubuntu yet). What can I do to repair my OS/hard drive?

A:Error loading Operating System

Well...IMO...if the hard drive can't be seen in linux...that would be an indicator of a possibly failing hard drive, with just a matter of time before all goes awry.
First thing I'd do is move anything off that drive...to a safer location.
Then, I would run a hard drive diagnostic on the drive, with the expectation of bad news.

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!

Hello and Welcome to TSF,

Enter bios: press F2 when pc first turns on
Boot order:
cd/drive rom
other devices (varies)

First lets test the harddrive.

Go here for a HD utility:
use seagate tools if yours is not listed, otherwise you can use these below:

dban - http://www.dban.org/download
killdisk - http://www.killdisk.com/downloadfree.htm

Burn the image to a cd:

perform a harddrive test, if harddrive test passes then
perform a full erase of harddrive.

if everything goes smoothly, proceed onto installing xp windows

After windows is installed, install drivers next.

Go here for the drivers for the pc:

Note: install the chipset first before any other drivers, reboot pc after each
driver install.

install protection - antivirus and antispyware protection for the pc.
Update windows using the window update icon under start button, all programs

So I have a dell inspiron 1720 laptop and I have gotten rid of vista. I have been using tiny xp and just recently decided to reformat after a virus bomb. I was going to particion my drive space so the OS would be in it's own part just in case it happened again I wouldn't have to lose some info. In the middle of the reformatting it lost power. When I try and start up the comp again it gives the error loading operating system message, and when I try to boot from the disk it gives the same message. So I can't continue formatting. I'm doing a diagnostics test right now to see what errors it gives. Is there anything anybody could think of to fix it? Any advice is much appreciated. Thanks.

Anyone encounter this problem all of a sudden?
I just happened to be working on my pc, deleting some old apps and things stored in My Documents.

I am an advanced pc user running Windows XP Pro SP2.

After deleting a lot of things I had stored in My Documents, I decided to reboot before running a defrag.
Upon rebooting, I got this black screen immediately saying "Error loading operating system".

I ran an advanced test on my Hitachi HDD using their Fitness Tool and no errors came up.

After thinking about it, I decided to boot up off my Windows OEM CD. At the menu I chose "R" to go into the Recovery Console.
At the prompt I typed "HELP", and it gave a list of commands.

I figured my Master Boot Record was corrupt so I typed "fixboot" and hit Enter.
I exited the Recovery Console, removed the cd and rebooted.
Problem solved!

I would recommend trying this before trying most of the suggested options that come up when you Google this problem.

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
