So I tried installing Windows XP Professional alongside my existing Windows 7 Home Premium as a dual boot, but when my PC restarted following XP's text-based installation phase, I got the annoying "Error loading operating system error. I've tried:
- Using the Windows 7 Startup Recovery feature from the Windows 7 DVD, but it didn't work.
- Deleting the incomplete XP partition. That hasn't worked either.
- Using the Windows XP CD to enter Recovery Console and run fixmbr. Unfortunately it asks me to log into my Windows 7 installation using the Administrator password, which is wrong every time I enter it. So I can't do that either.
I have an Asus laptop computer with Windows 7 and when I turn it on I get this message, "error loading operating system." Just those white letters on a black screen, nothing else. I have had the computer for about a year and a half, and have not recently loaded anything new onto it.
The only thing I have found I can do is press F2 when the Asus logo pops up and this takes me to BIOS setup utility.
When I turn on my computer it comes to verifying dmi pool data and after about 10 seconds it says error loading operating system. than i restart my computer and it boots normally. it happens over and over again.
I have been trying all day to dual boot using the tutorial and no success.
I have windows 7 install on my computer. I want to have windows xp.
Now I have shrink my hard drive so I have 2 partitions now. Ok the problem is When I boot xp I goto install on D:/ the new partition it then copies all the files to that hard drive all good so then it wants to restart which is normal.
Then When it reboots it will say error loading operating system or just nothing.
Then I cant even Run windows 7 I have to delete that partition on windows xp and then put windows 7 and repair startup and Im back on again. It has to do something with the boot loader or something because I reckon Its trying to do start windows 7 but there is xp trying to install it self. Im not sure but I think I have tried every idea.
I had to mess about getting rid of the virus but it left residual files that were causing me even more problems. One of those files, veawi.sys, refused to go away as everytime i tried to delete it i would get a message stating that "a device attached to the system is not working" or something along that line.
Anyway, i tried to get rid of it by installing Windows XP to a USB hard drive that i have lying around so that i could use the command prompt to delete the file from the windowssystem32drivers directory. That didn't work as i would get the message "NTLDR is missing" and my Windows 7 installation wouldn't boot either as i'd get the message "Error loading operating system". To add insult to injury i found, after using the installion disc for Windows 7, that i could have just used the command prompt in the repair section of the disc which allowed me to get rid of the culprit file.
I've tried running the startup repair from the Windows 7 disc and it states that there are no errors found. For the first time in ages i'm stuck and i get the feeling that i'm going to have to reinstall Windows 7 all over again.
During a recent windows update my pc froze, (mid-update) and I restarted my machine. Now windows gets stuck at the black" Loading operating system..."screen. After a long wait it will eventually display boot from cd/. When I boot from my windows dvd my os is not shown in system recovery. I Have also tried running start up repair from recovery with no luck.
So I popped the top off my desktop, removed my wireless card and was checking to see if the card would fit in a PCI slot (it's a PCI-E and it does not). I then re installed it and started my computer up. I was prompted with a hard drive option (a Y/N option) of which I chose N. I don't know exactly what it was asking but I am trying to get it to re prompt the menu.This lead to me getting stuck at the Loading Operating System screen. I was able to boot to windows by manually booting via F12 to my 128gb SSD. This successfully booted to Windows. I noticed that the interface was a little buggy (The date was 3 years off and not all the icons were appearing). I re booted, was prompted with the same Y/N, Chose Y, and was still stuck at the Loading Operating System.I can boot manually to Windows using F12 but something feels wrong due to the date, ect.Is this a MOBO failure? The NIC Port of the MOBO recently died on me so I don't know if the MOBO itself is dying on me. The computer is less than a year old and was built by me.
i was on my computer surfing the internet when i got a BOSD and restarted my computer it kept happening when i was on the internet so i ran a chkdsk and mem testto see what it could they oth came out clean and i was stumped. i left my computer alone but after a few days i turned it on and decided to try plaing a game and it worked i played the game fora few hours and when i turned it off i was bombarded with messages from this program called win 7 home security that somehow turned off my windows defender 'i tried running a scan with my nod32 antivirus software but it came up clean. this program wouldnt let me go on the internet it kept saying i was unprotected and that it wld save my computeri tried to find a way to uninstall it and i looked for the directory that it was in but i couldn't. so i decided to restart my computer and go into safe mode but when i restarted my comuputer
my computer started laggin really bad, couldnt even move mouse without major lag. Anyways so i got sick of it and reinstalled windows 7 64 bit, now my computer gets stuck at loading operating system. Thought it was SSD so took it out and put in a 500gp wd hard drive (I know it works fine, becuase had it run on company server all week before i used it) so then i installed it on their and still was stuck so then i took out my other 500gb wd hard drive where i store all my files, just so i could make sure that my OS can only install on one item and not be corrupted by any other drives. So now the problem still presit and i have tried resetting my bios by taking out battery for 10 min, still no results, so then i ran startup repair (Had no hope) and it still didnt work. Need help and bellow I will post all my hardware, by the way my computer is a custom build and has been working fine for 2-3 months. Also I do overclock, but i doubt that had anything to do with it, because it started to lag weeks after i started overclocking. [code]
I left for work this morning, and my computer remained on as per normal. Nothing stressful left running only skype and a browser as far as I can remember. Come home and find that the screen won't move from being black. Restart and it loads up normal until it says "Loading Operating System..." It then moves to a black screen which after a few seconds fades out to an even darker black. Then nothing happens. I have/am trying to run the repair tool via CD boot of my Win7 disk but it is incredibly sluggish. I've been waiting to even see the repair tool for an hour each time before I get frustrated and retry. Also I cannot enter safe mode via spamming F8. It seems that my Win7 went rogue and decided to move out
The first problem was that it kept booting into the windows startup repair. For a split second i can see windows 7 loading but then it automatically went to the startup repair , after many many reboots i opened the command prompt in windows startup repair and tried fixing the master reboot.Now it gets stuck at loading operating system.Even when i try to boot from the windows 7 CD and Truecrypt rescue disk it still gets stuck at loading operating system.The whole harddrive was encrypted with truecrypt and it use to go to truecrypt bootloader after loading the operating system but it doesn't do that anymore.

I am attempting to reinstall windows with files burned from an .iso onto a blank disc but when I press f12 then go into CD-ROM it goes to the next screen and says: 'Loading Operating System... Boot from CD/DVD..' Then it will boot normally.
"Missing operating system" massage is coming when i start my system and i am not able to start. I think because , i had given "mark partition as active" option for one hard dive (E) in disk management when last time i opened. it did not have any data. i did not know, this will make any problem. Now i am not able to boot windows re installation dvd also. i can only take BIOS settings.

This is my first post and wasn't sure which exact board to post to so I thought installation might be one. I have a windows 7 64bit machine installed on a 250gb hdd. Here is the exact sequence of events. Shutdown computer last night (it had been on for 2 days straight). Turned it on this morning, bios screen loads fine then it jumps to a black screen with the text "Loading Operating System..." and it hangs there. I tried multiple configurations to detect the problem. I feared for the life of my hdd. I unplugged my other 2 hdd and the dvd drive from power and sata and rebooted. Now I get "Loading Operating System..." BOOT DRIVE FAILED INSERT CD AND PRESS ENTER TO CONTINUE. Re-install any other drive combo and get the standard hang screen. I made no major changes to my setup in the last 2 days, no software, no windows update, no hardware changes whatsoever.
The other day I assembled a new built PC and then went to go install the OS. I tried using a boot disk of Windows 7 Pro x64 but right after the POST it immediately goes to a screen where it says "Loading Operating System" and just hangs there. I have tried various fixes I have seen on other sites but can't get it it to move on.

i have an hp pavilion that fell down, now when i turn it on in order to to boot from the hard drive i need to put booting cd (windows booting disk)to boot up the hard drive or it gives me an error message (no operating system found).
I get the "operating system missing_" error on power up of my lenovo ideacenter that is 4 weeks old. I have recently installed the net from Time-Warner on cable.. I called lenovo and the tech gave me the "press F2 while turning the power on to it". This works but why do I need to do this? What gives with it working and then it doesn't .... I have not moved, touched, jostled it or anything to it that I didn't do when it was first installed. It works fine but will this indicate a future of trouble? I have virus protection from McAfee is this not enough?
I have an Acer Aspire One that was running Windows 8 consumer preview. I wiped the hard drive and tried installing Windows 7 starter from a USB drive then from an external DVD drive. I set the boot order for each install in the bios, but still get the Missing Operating System error. Do I have to change any other settings in the bios? Why won't Windows 7 install?
i recently installed Ubuntu 12 to run alongside my windows 7 home premium. I later uninstalled Ubuntu and now whenever i boot up it says missing operating system.
i have sony viao laptop, when i start my pc it shows the following error " operating system not found "when i opened bios menu, it doesnt detectes the hard drive n says " no drive ".hv my hard disk crashed ?
Ok, so in the process of overclocking, I rebooted my computer and then got the "Missing operating system" error. I reset the CMOS and that didn't work, in the process of trying to boot from my Windows 7 disk/Linux distro's so I can see if one of my drives crashed but nothing seems to want to boot, so I am at a loss. Also, it seems in the BIOS, some of my SATA devices aren't being recognized. That may be because I reset the CMOS but I'm not positive. I can only see one of my SSD's in the BIOS and one of my optical drives.

Using the Windows 7 DVD that came with the machine I went through the repair Windows procedure 3 times. The first time it searched for restore points of which there are none because the machine has Rollback Rx installed instead. It then restarted with no change. I went through the same process but this time it said it had repaired Windows however; restarting gave me the same missing OS message. On the 3rd attempt it displayed the restored OS as being on D:. I ran the diagnostic tool and it said no errors were found. Restarting gave the same error.
Ran F12 to regain Operating system - long version. Says computer passes everything but there's no operating system found. Did this Twice. Tried "Operating System" CD that came w/ Studio 17 laptop. Hit option to run via CD & never got anywhere after an hour. Tried Reinstall Hardware disk that came w/ laptop. It shows Vista, but laptop came w/ Windows 7. See where it shows the system's checking things out, but never get anywhere.
as usual I turned off my laptop and after a while a turned on again to use my laptop but it couldn't reach operating system and showed error : " OPERATING SYSTEM NOT FOUND" !
I tried all instructions to solve the problem and finally run by windows start up CD to re-install new windows. this time I faced error: " No drivers were found. click load driver to provide a mass storage driver for installation"
I have a Sony Vaio laptop which I did not originally purchase but traded for my iPod touch. This Vaio has a Windows Vista sticker, but the man I got it from told me he installed Windows 7 Ultimate on it. He did not tell me that it was a Release Candidate version. I found that out after 2 hours of using this PC, when it suddenly restarted. After June 1 it began notifying me of the RC issue, it being expired.
So, this week I finally decided to get rid of the RC version. I purchased a new Windows 7 Ultimate package and downloaded KillDisk (Active@ Kill Disk Hard Drive Eraser. Low Level Format.) to swipe my hard drive clean. I burnt KillDisk onto a DVD and ran the program, which was successful.
Afterwards I bought a new Windows 7 Ultimate package, tried to run the DVD but it now gives me the error "Operating System Not Found".
The BIOS on this Vaio model does not have a whole lot of settings to change, so what do I do???
Suddenly my Win 7 Home Premium x64 will not boot. The system starts, POSTs then loads the DVD driver, then the screen goes black (not blank but "lit up" black if that makes sense). Then nothing. If I use Hiren's boot cd I can boot up using the "boot from HDD" option fine and Windows operates normally. System restore to a previous configuration made no difference to the original problem. I cannot boot into Safe Mode. F8 just offers me boot order options.
- Running the Windows 7 DVD I find: "No operating system is listed on the Repair Windows option." - Running Startup Repair finds the following error: "the partition table does not have a valid system partition" which it claims to have repaired, but the error remains and Windows will still not boot.
I followed this advice: Boot 7 dvd to system recovery options command prompt. Type: Diskpart list vol (find the vol letter e.g C or partition number e.g. 1 for the system partition ) Sel vol C ( or sel vol 1, obviously use the correct letter or number) act exi
My system partition was easily identified and listed as healthy so I selected it and made it active. The problem still remains exactly the same. My system is self built just over a year ago, to my knowledge has been running fine, without any hardware issues. I'm prepared to do a clean install if that's what it takes but if there is a way to fix the partition problem without that I'd like to explore it first.
I am looking to upgrade my desktop from an xp to 7. System builders are very cheap which concerns me. What is the difference from a system builder and the regular version.
