Upon booting up my laptop, everything seems fine at first. My desktop loads as does any startup programs as normal for a good few minutes until the startup procedure is finished, then simultaneously any programs I have open fail to respond and after a few more minutes my operating system fails to respond. Between the time of the programs and the operating system failing to respond, I cannot execute any other programs nor can I lauch task manager (CTRL+ALT+DELETE etc.). A while after the operating system fails to respond this error pops up, no doubt as a response to me trying to open task manager:"Failure to display security and shut down options. The logon process was unable to display security and logon options when CTRL+ALT+DELETE was pressed. If the operating system does not respond, press ESC or restart the computer by using the power switch."
All this occurs without fail everytime I boot up as normal.I can boot up my laptop in Safe Mode with success which has allowed me to try a number of things but I am no computer tech so my knowledge is slim to none. These are what I have tried:
1) I have run anti-virus and anti-malware programs which came back clean.
2) I have tried to go back to a system restore point but apparently I have none.
3) I have tried a clean boot up (with only Microsoft start up procedures) but did not help, just made my OS fail to respond almost instantly as my desktop loading instead of after a fair amount of time.
4) I have 'restarted winsock' on a forum suggestion from another post it may be a particular virus and rebooted but this did not help.
5) I have turned off UAC and rebooted incase something was making changes causing Windows to fail to respond from another forum suggestion. This did not help either.
6) Rebooted with last known working configuration option.
I should also point out I have not recently added any hardware or software that could make this occur. However, maybe the last 3 things I did before the problem occured could help explain. Firstly, I ran a full anti-virus scan with AVG which removed a rootkit and deleted something 'malicious'. After that I used AVG PC tuneup to clean the registry, defrag and clear junk files. Lastly, I tried to run Steam which froze on an update and I tried to restart my laptop, which froze on the "Logging off..." screen for ages by which time my laptop battery must have died. After this the problems arose.
I really want to avoid anything which might have to result in my reinstalling Windows 7 as my laptop came with it pre-installed so I do not have a Windows 7 disc or a OS backup.
Laptop:- Sony Vaio VPCEA3M1E, Intel Core i3.
OS:- Windows 7 64bit Home Premium
I have a Acer Aspire One 722 netbook and there are times when the system hangs and does not respond. The cursor does not move and there is NO option to "Restart Windows Explorer"( a common option when your system hangs). I am waiting for this to show (about 10 mins) but nothing happens. Only a beeping sound is heard from my system but it does not came from the inside of the laptop but from the audio speaker. The only thing I would do is to restart it manually(by pushing the restart button). Now my files had not been saved. But, fortunately the unresponsive instances does not happen every time I switch on my netbook.
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.
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.
"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.

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.
whenever i boot my pc i starts making sounds for like 15 secs and later asks me t choose my operating. this started wheni removed my battery for like 3 weeks and then inserted it back. am using acer mini.
I have tried to restore my system to an earlier state to remedy the faulty uninstallation of a speech recognition programme, which tries to reinstall every time I start the computer. System restore restarts the computer but then tells me the restore process failed, once i am back to my desktop. OS is Windows 7 Home Premium and computer is an Acer Aspire laptop. System partition is encrypted using Truecrpyt.
I am installing Windows on my new SSD. I made the disk GPT (instead of MBR), and installed Windows (tried 5 times now) with similar results. Either error 0xc0000225 or boot loop of "Windows is loading files" ... or it throws me back to my BIOS Boot selection screen where I came from ... what might be the problem? Windows 7 still cant handle GPT partitions? Or it doesnt like the new SSD? I managed to install and reboot successfully once by removing all other drives (except the SSD which I am installing into), works, I can enter Windows. Then once I installed back the other HDDs, it fails again ...
I was just wondering is there anything within the fabric of your p.c. (the p.c. equivalent of a clothes label) which specifically states its operating system.I have Windows and Windows Office 2007, but as I said, is there anything that clearly stipulates on my hard-drive which operating system I am using.
After assembling the new computer, I ran it without the system disk installed to make sure everything was kosher, and memory timings, etc. were correct. After verifying that, I shut it down and put the SSD into the new unit and booted it up. The system posts fine, but once the Win 7 startup image shows, the system restarts and brings me to the "start windows in safe mode/start windows normally" prompt.
I tried to restore my laptop to factory default today and i must have clicked the wrong option because it deleted my Hard Disk. now when i try to start it it says Operating system not found. Is there any way i can fix this? Oh and i have Windows 7 Starter edition, and its a Toshiba notebook laptop
This morning my computer, Sony Vaio, was working perfectly. I turned it off and after a couple of hours put it back on, to get to my surprise the following message " OPERATING SYSTEM NOT FOUND".Is it possible to recover my information still?
the boot manager was missing for my dell inspiron n4030 so i put the windows 7 repair disk in but when i start it it doesn't have any operating system listed
have got windows 7 ultimate version of operating system on my system, . but i also want to install windows xp in it for some reasons related to my education. can i install an other operating system along with the existing one, such that at every start up i could select the required os to be functioned
Basically I loaded up my Sony Vaio PCG-71811M laptop and it just has a black screen with 'operating system not found) I clicked F2 for the utility help to see what it said about the HDD. It doesn't say 'HDD not found, all it says is '0GB'. Really worried because all my university work is on there
I dropped my acer extensa 5235 from 1.5ft it landed flat. But now when i turn it on it says "operating system not found". Ive been searching everywhere for a solution but have not one. I do not have my windows 7 install disk as it was already pre-installed but i do have the windows 7 iso on a usb-stick. But when i go to install from the usb and choose custom install it starts to "Copy Window Files" but stays at 0% then an error comes up and says "Windows Setup could not reinitialize the deployment engine. To install Windows, restart the installation." ive tried to restart the installation but always comes up with same error?
I'm studying abroad in France and made a the great decision to try to restore my laptop to a system image on an external while in class. Anyway, my battery died half way through and on start my machine says missing operating system. I don't happen to have my restore disks here and would prefer to not have to go rebut windows 7.
My laptop is a HP Pavilion dv6500 (dv6647cl) just crashed randomly during basic internet browsing. I turned it back on and I get the Operating System Not Found error. In the BIOS I do not see the hard drive recognized. I connected the hard drive to a different computer and it is recognized and it appears as though nothing is wrong with the drive. Is it safe to say that internally the SATA controller is dead? Will edit after running diagnostics and sector tests on the drive.
My rather new Sony Vaio started having BSOD crashes, usually (but not always) after being asleep. After the BSOD, the restart would fail, with a message saying the operating system could not be found. But, after a couple restarts or a cold reboot, it would find it and start without problem. I reset the bios to defaults, did a system restore to before the crashes started- no luck. To make matters more complicated, the BSOD flash so quickly I don't get error codes, and no matter what I do (check pagefile size/location, system settings), my computer doesn't make a dump file. The event viewer only lists a critical error that the system rebooted without cleanly shutting down first. I called Sony, they had me run one of their hard drive check programs (not chkdsk and it passed), and then made me reformat/recover using the hidden partition and their recovery software. Besides the annoyance of the clean reformat and all my software settings etc not restoring quite right, three days after the reformat and I have another BSOD, and again, no .dmp file or any other clues (and of course, all the previous error reports got wiped).
I've had a problem with my ACER Laptop, and I need help fixing this Black Screen Of Death. I started up my laptop today, and BOOM! An error popped up and I have no absolute idea how to fix it. [code]
When did stability become an issue with operating systems? Was it around the time dial up modems were used as Windows monitor stands? Surely such a stack was not as stable as when people used to put monitors on top of thick telephone directories. Was it when combinations of operating systems and programs often failed for no apparent reproducible reason? What happened to all the operating system bugs? Surely the bugs did not disappear as operating system stability became a concern. I'm trying to pin point the year. I guess it would be the mid 1990s but I'd like to hear your opinions.
I have an Asus K60I, and when I start it up, a message appears telling me to choose an operating system, and gives me two choices...
1)Boot Client OS 2)Boot MRI PE
When I go to advanced system settings -> startup and recovery-> there is nothing listed under Default operating system, and the dropdown menu is empty.
My sony vaio is about 2 years old with a Windows 7 64 operating system. I changed the hard drive to a 500GB Toshiba. When I turned the computer back on it said "Operating system not found". I was told to turn off my computer and then restart while pressing F2. The new hard drive showed up on the screen. Then I restarted the computer again while pressing F10 but it says "Operating system not found".
Have just registered to see if anyone has any ideas for a solution to a problem with my that is running Windows 7 (I think 64bit). It refuses to boot and just says "missing operating system".Using the repair option on a boot disc does not work (have tried 3 times)If I boot using a windows 7 cd/dvd I only get given the option to install windows.I can see both hard drives in the BIOS.I am able to get to a DOS prompt using the boot disc, but have no idea about DOS myself.When booting from the Windows 7 cd I was able to see the C: drive but it would not open, saying it needs formatting before use.I think that's about it, will post anything else relevant if I think of anything.
I have a Sony Vaio VPC-EC2TFX/WI, Have tried rebooting several times with no change.This computer was working fine last night and when I tried to turn it on this morning, I got the Operating System Not Found message
I have a Windows 7 Computer but I want to put Ubuntu Linux on a separate partition. I can't figure out how to do that. I already have the iso and have a new partition
