Operating system not found - Windows 7, Sony VAIO
When I start my laptop, it gives the error operating system not found. I have a repair disc, a recovery disk and also a backup system image. I am able to do nothing, as the laptop does not go past this message. In the past, I used to get this error once or twice daily, but when I re-set with Ctrl + Alt + Delete, the system would begin. No critical errors were found in the Eventlogger. How to start the repair process?
Hi vasanjs,
1. did you of recent changes on the computer?
This problem may occur if one or more of the following conditions are met:
(a) basic input/output system (BIOS) does not detect the hard drive.
(b) the hard disk is damaged.
(c) sector 0 of the physical disk has an incorrect or malformed master boot (MBR) record.
Note Some third-party programs or alteration of the disk can damage an MBR.
(d) an incompatible partition is marked as Active.
(e) a partition which contains the MBR is no longer active.
Method 1
I suggest you update brings input/output system (BIOS) to the latest version by contacting the manufacturer of your motherboard or computer and check if it works.
Important: Change (CMOS) BIOS/complementary metal oxide semiconductor settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.
BIOS: Frequently asked questions
http://Windows.Microsoft.com/en-us/Windows7/BIOS-frequently-asked-questions
Method 2
If the previous step fails, then I suggest that you perform repair system on the computer and check if it works.

I would recommend that we run a SFC (System File Checker) first scan to see what he finds. Try this:
1. click on START
2 type "msconfig" (without the quotes) and press enter
3. go to the "Startup" tab and uncheck all the entries displayed
4. click on 'Apply' at the bottom right
5 restart your computer---
After the reboot
---1. click on START
2. Type "cmd" (without the quotes). Right-click on the result at the top of the menu START and select 'run as administrator '.
3. type "sfc/scannow" (without the quotes) and press enterIf the question started very recently, you can try a system restore:
1. click on START
2. click on "all programs".
3. click on "Accessories".
4. click on "system tools."
5. click on "system restore."6 follow the prompts shown to restore your system to a date before the problem started. Although the system restore does not target the personal data, it is recommended that you back up all data such as music, photos and documents in case something is not bad.
Let us know what happens

"OS not found"
Hello... My laptop out there today and I'm trying to start it, it says "operating system not found '... I guess I reinstall windows Vista but I can't find any cd/dvd... I dontt think that I was given when I bought my laptop a few years ago... Do you think I can get another copy (free of charge)) LHello
If you have never received a recovery disk when you bought your laptop there should be a recovery Partition on the hard drive to reinstall Vista on how you purchased your computer.
The recovery process can be started by pressing a particular combination of the key or keys at startup. (Power on / start)
Maybe it's F10, F11, Alt + F10, etc., depending on the manufacturer.
Ask them to the proper key sequence.
Also some manufacturers have more available recovery Vista disc.
If this happens, you may need to try this instead:
You can also borrow and use a Microsoft Vista DVD, which contains the files for the different editions of Vista (Home Basic, Home Premium, Business and Ultimate) must be installed. The product key on your computer / Laptop box determines what Edition is installed.
Other manufacturers recovery DVDs are should not be used for this purpose.
And you need to know the version of 'bit' for Vista, as 32-bit and 64-bit editions come on different DVDs
Here's how to do a clean install of Vista using a DVD of Vista from Microsoft:
"How to do a clean install and configure with a full Version of Vista '
http://www.Vistax64.com/tutorials/117366-clean-install-full-version-Vista.html
And phone Activation may be necessary when you use the above installation method.

I have an Acer Aspire 5516, with pre-installed Windows Vista. I didn't know that it did not come with a recovery disk UNTIL my system crashed! During a routine virus scan, I got a blue screen saying a major problem has been found and the system has been shut down. I followed the instructions to gracefully shut down my laptop. When I turned this back on after the "Acer" logo he went to a black screen with info on my computer and the last line States "not found operating system". That's when I discovered there was no recovery disc & it is integrated into the system. To access this system you we F8 to enter safe mode, then Alt F10 to access 'erecovery management system. Neither one of these functions operate! Still getting the black screen with "operating system" not found I have a Windows XP my laptop previous. What I was wondering is if I can load on my Acer, possibly on a partition, in order to be able to get into my laptop and save all of my files? I'm terrified of losing everything I have! I have thousands of pictures that I can't replace. If anyone can help please do! I am on a very limited income & can not really afford professional help. Thank you very much in advance!
Hello
normally with an Acer you press Alt + F10 at startup to start the hidden recovery partition recovery, not F8, then this combo
but you do not have an option to save your data, that
in daily use acers normally have a system partition, a partition of data to save your data, etc. to and also this hidden partition recovery
and read this on data recovery, too;
Data recovery
1. remove the hard drive and it slave in another computer
2 buy or borrow a USB disk drive hard put in yout case then plug it into another computer and read the hard drive like this
3. try Knoppix
http://www.Knopper.NET/Knoppix/index-en.html
BUT this method 3 depends on your hardware in the computer that failed
read this information about method 3:
http://www.Knopper.NET/Knoppix/index-en.html
Download/save the file Knoppix Live CD ISO above.
http://isorecorder.alexfeinman.com/isorecorder.htm
Download the Vista software from the link above.
After installing above ISO burning software, right click on the Knoppix ISO file > copy the Image to a CD.
Knoppix is not installed on your PC; use only the resources of your PC, RAM, graphics etc.
Change the boot order in YOUR computer/laptop to the CD/DVD Drive 1 in the boot order.
Plug a Flash Drive/Memory Stick, BOOT with the Live CD, and you should be able to read the hard drive.
When the desktop loads, you will see at least two drive hard icons on the desktop (one for your hard drive) and one for the USB key.
Click on the icons of hard drive to open and to understand which drive is which.
Click the icon for the USB drive and click on "Actions > Change the read/write mode" so you can write to disk (it is read-only by default for security reasons).
Now to find the files you want to back up, just drag and drop them on the USB. When you're done, shut down the system and remove the USB key.

'Operating system not found', can't the recovery partition, do not have a recovery disk
Original title: recovery Partition not here and not backed up copy of Win8
I have an 18 month, Acer Aspire V5-571pg now out of warranty. For the last 3 days, of what it has been in a loop bringing repair until this morning disc error messages, it just says "operating system not found '. A call to Acer support and we have tried to activate the recovery Partition using Alt - F10 but it seems that the partition is not there either, and of course I did not create a recovery disk when I got the laptop. I was not eager to send the Acer laptop for service after the warranty expires, I thought I should at least attempt of recovery or re - install. Windows 8 is a preinstalled OEM version. Where should I start? Y at - he's going to be a download that I can use and what I need to know a product key to install? Should I get Acer to send me a recovery disk? Not super PC here but am knowledge letter wins all the time. I hope someone understands my situation. Thank you

Hi all
I recently installed a mod for S.T.A.L.K.E.R SoC V1.004. The game won't start not even, instead, it gives me the following message:
This application is not compatible with the operating system installed.
Please upgrade to Windows 98SE, Windows 2000 or more.I'm under Win 8 64 bit. I have uninstalled and rebooted twice (both game and mod) does not.
I have to downgrade to XP to be able to play this awesome mod, he ran on this platform with the same configuration before, why he now rejects it know not only the people at Ms.
Please help if possible
Thank you very much
Pierre Viljoen
Probably, all in all probably is a 16-bit program, and as such does not work on Windows 8.0/8.1 64 bit. In addition, the game seems to have 20 years or more. You can try running in compatibility mode, but I think that the game is dead. Hope this helps and if you need help please post and we will be happy to help you.

Windows operating system not found-8
I was reset my pc because of the way of a lot of information and a power cut interrupted and now I just get the operating system not found. I upgraded my computer from windows vista to windows 8 digitally so I did not have a boot disk. I tried a USB windows 8 recovery of my family members pc, but when I troubleshoot it gives a similar answer that I don't have an operating system. The hard drive seems to be working and I can find it on the boot options and start, but I can not any more than that. Help, please!
I see three things at this point in time:
- Try resetting once more
- Use the combination of keys SHIFT + F8 and try to start in safe mode
- If you have a parallel operating system installed, load your computer in.
-
Error database that can be updated windows detected 0x8007000D - not been fixed in Windows 8.
Original title: slow startup and commissioning, also blocks windows 8
My computer began to take 10 minutes to start and run. then hangs every now and again when I use it.
I had problems installing an update and I thought that was the problem, so I followed the instructions and installed the update (KB2855336) on a clean restart. When I put the settings back to normal reboot I see the update succeeded, but the computer is still a good 10 minutes to restart.
I tried to do a repair, but this is notauto-start.
I tried to run a sfc/scannow and that froze the verification step 100%, I have waited a long time, checked in the Task Manager and saw that he was inactive and if you click end task.
My Task Manager shows 99% or 100% use of the disk.
I tried to do a system restore to a point in mid-July and which failed, error 0x80071a90 code.
I followed the advice of someone to uninstall the update and restart twice, but the problem persists.
What can I do to fix this? I use my laptop to work and so I need this problem as soon as possible.
I just tried in safe mode and also it took forever to start and run. I tried different jumpers in safemode, maintenance of the system not found no problem, windows update however found two:

ProBook 450 G2, core-i5: operating system not found
Hello
I expanded the partition of my C drive with force to upgrade to windows 10 since an iso file... then after restarting, I am facing the problem "an operating system is not found. Please remove storage external use... »
I tried to boot from the start menu by pressing F9 while restarting, but no solution met! I also tried to boot from EFI file, but does not because no options that are there found.
The disc is also OK, checked the BIOS settings option.
Now what to do?Spoiler (Highlight to read)Hello;
Let me welcome you on the HP forums!
I read your post about the operating system not found since the Win10 Upgrade failed and tried to help.
One of the things that happened during the upgrade:(1) it mostly completed but failed in the writing of the new boot loader files
(2) it failed early in the upgrade, screw up your PC as well
Allows to process 1) first - by recreating the bootloader files.
You need access to a PC for this phase of work in order to create the necessary support to fix your PC boot loader.
Once you have that, please download and create the Win10 installation media from this link: http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10
Note that when you download and build install media, the default tool corresponding to what is already installed on your PC (as in home for the House, and 64-bit to 64 - bit). While you CAN change these settings, are NOT. If you do, the media that results will be different and will force you to enter a NEW product code.
Boot from the media that you have created and follow the instructions in this link: http://www.tenforums.com/tutorials/2294-advanced-startup-options-boot-windows-10-a.html
You will need to go to the Advanced Options screen and click on startup repair. You will probably need to run Startup Repair three times for him to fix all the boot loader.
Once completed, your PC should start OK.If this does not work, then we are on option 2) - which is not good news.
While Microsoft says there is no risk in the upgrade of Win10, because they allow you to believe that you can always return to your BONES and the original installation program within 30 days, the ugly fact of the matter is that the Win10 GoBack feature turned out to be unreliable - and when she fails, she can let machines in a State corrupted - that does not always happen , but it happens often enough to be a problem and you will get no warning beforehand that he goes to the trash your PC!
If this is not enough, the Win10 upgrade is known, in some cases, corrupt partition recovery stored by the OEM that built the original machine. It's pretty much guarantee that no HP recovery will work.What will work restores your computer to its original factory state using HP recovery media.
It is a set of DVD and a CD or a USB key, which will erase the hard drive (removing all data, applications and settings, reinstall the original OS, drivers and utilities for HP. In some cases, you will be able to order a USB instead of discs. You must order at HP; they cannot be downloaded.
You can look online for recovery from the paged media related: http://support.hp.com/us-en/drivers
Once there, enter your product name or number. On your software page and download the drivers, select your operating system and version. Click on "Update". If the HP recovery support is available for your computer, down near the bottom of the page, you will see an entry for the command Recovery Media-CD/DVD/USB. Click on the symbol '+' to expand this entty and click on order to press for more details.
Or, if you prefer, you can do the same by contacting HP Customer Service:
If you live in the United States or the Canada, details are on this page: http://www8.hp.com/us/en/contact-hp/phone-assist.html#section1
