Preferred Solution: Missing operating system problem in vista

I recommend downloading and running Outlook PST Repair. It's a PST repair tool that I've used it in the past to recover emails, contacts, tasks and notes from corrupt Outlook files that are damaged or inaccessible. Supports Outlook 2000, 2002, 2003, 2007, 2010 and 2013.

You can download it direct from this link http://goo.gl/1bjhSi. (This link will automatically start a download of Outlook PST Repair that you can save to your computer.)

If you have a Vista installation disk you can boot to the cd drive and use the recovery tools on the disk. If not you can download a Vista recovery disk here.

I turned on my Lenovo desktop and the 'missing operating system' message
appeared. I have had no previous problems. What can I do?

A:missing operating system (vista)

It normally indicates your HDD is caput. You could look in the BIOS to see if the HDD is recognised.
If you are out of warranty you could open the PC case and clean out any dust and then remove and replace the HDD.
If that doesn't work it is likely you'll be up for a new HDD and reinstall of OS and applications - hope you have your data backed up.
Sorry I can't be more positive..
You could try Lenovo support.

Are you able to boot to safe mode by pressing f8 during the boot process?
A system restore may be able to do the trick, else a windows repair maybe.

Purchased my HP media center PC 11/26/06 with XP installed and a free upgrade to Vista. Upgraded to Vista in April with no problems. I purchased an Ipod in July and while installing Itunes, the system crashed with a blue screen that ended up with something like "memory dump." Had to physically turn off computer and when turned back on had a message "missing operating system." Called HP and Itunes and ended up having to restore computer. Have had this happen on two more occasions. This blue screen comes on frequently while working in Adobe Photoshop Elements 4.0. Recently upgraded to 6.0 and have had no blue screens. Last night computer was acting fine and I turned it off. Today when I turn it on I receive the "missing operating system" messsage on a black screen. I am tired of restoring this computer and reinstalling all my software and backups. Any ideas on solutions to my problems? Is there a way to get around having to do a restore and then reload Vista, etc?

The computer has an AMD Athlon 64 X2 Dual-Core processor 5000+, NVIDIA GeForce 6150 LE graphics card; 21048 mb of memory, and a 320GB hard drive.

Hi anyone that can help me

I have had my comp for a few years now an never had this silly problem till now!
I switch on comp and I get the option of pressing f2 or f8 and when I press them I don't understand what to do next....I am not too well advanced in computers! My machine is a Packard bell with intel pent 4, on windows vista (home premium) I think.

I can't afford to buy any fancy software etc so I just need to know my best option. The only thing that I have is a recovery disc 1 that I downloaded when I bought the comp I don't recall any other discs.

I would really appreciate any help.
Thanks for reading.

Hi, i'm new to here. I just got to know that techsupportforum.com is helpful from Yahoo. So i hope someone here can solve my problem.

I just got a new computer from Dell C521 yesterday. Then, i on the computer and trying to install new applications from CD to C drive provided by Dell (eg.: Microsoft Works) and other mp3 songs from my own cd to my E Drive. C drive is for OS, and D drive is Dell recovery drive. However, everytime i tried to install new softwares or copy mp3s to my computer, after that i restart or reboot my computer, a black screen with an error message occur saying that "Missing Operating System".... So i reformat again the OS with the CD came from Dell. Then doing the same things.... and restart it. Same issue happen. What is the problem out there?

However, if i do nothing on my new computer (no install any softwares or copying files to my pc) my computer can reboot or run properly.

Well, i already contact local Dell supported team. They say will update me. So i hope can get their response soon. But i cant wait for them.

I have the same problem similar to the website below. In the mean time i already tried out these solution from Dell community website:

But it doesnt work for me. So can someone tell me the solution? My hard disk got no problem.

A:Missing Operating System - Windows Vista

dell stated that all computers that come with vista would come with the vista disk and instead of reformatting on the bottom left of the install screen
is the repair option
if the computer has sata h/drive after reformatting you probably need to load a driver with f6
the inicial install goes to ram and when it reboots it goes to load the h/drive
if it needs a driver loaded it will stop dead because it cannot find the h/drive

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?

Hi, I think this problem was caused by a forced shutdown ( I left it with a auto shutdown program, and when i come back to turn it on, i get this!) ( The shutdown program has never caused this problem before though )

So this is the choice page:

I've tried both and neither work, they cant get past the load bar.
I have put the disc in ( Windows x64 Business ) and attempted a repair, which didnt work. I attempted a system restore to a few days ago and still the same problem.

I do however get these two screens which pop up for a split second before the above screen, my camera managed to capture them!

This one first:
Then this:

I havent changed or installed any new programs or drivers.
Im running a 2.4ghz quad, 2gb of OCZ ram, geforce 260 GPU, and the OS is installed on a new HD

It was all running wonderfully, and now nothing

Please please help!

I have no recovery disks or anything, can I save my system???

A:Missing Operating System

Welcome to TSG....

Contact the manufacturer of the computer and order a complete set of recovery disks for thsi computer, they will arrive via snail mail with in two weeks after paying for them.

Also while you are waiting you can remove the hard drive from this computer and install it as a slave drive on the second IDE cable and when it is seen by windows then manually backup all of the important data from this drive to the computer it is installed in and burn to another media like CD-R's, DVD or other media that you prefer.

After this is done if you are impatient you can press F10 and try to restore the computer back to when the computer was brand new but this looses all of the data.

I am getting the message of "Missing Operating System" on the computer and the computer will not boot up. It is an old Dell (2000?) and belongs to a friend of mine.

I am NOT well versed in all this computer verbage but think if someone gave me some advice, I might be able to fix it.

I should also say that before I get the message "Missing operating system" a computer message comes on of "enter F2 for setup and f12 for boot menu."

I have a feeling I was in the BIOS part of the computer and might have switched a setting.

I used revo to uninstall that useless Pinnacle video editing software and the 200+ GB's of files and other junk associated with it. fter it ran, I used the revo tool that erases the unused space, IE permanently gets rid of, that those files used. I used Crap cleaner afterwards. I rebooted fine. I then started messing with my RAM voltages a little and when i went to boot I get, "Operating System Missing."

I have set my voltages back to levels at which the computer WAS working....... operating system missing
I have used the WD utility to check the hard drive, it checks out fine.
I have inserted my Vista installation disc (retail 64 bit Vista), and tried to do both a restore and and repair. "No operating system."
Bios sees the HDD as did the bootable WD HDD utility. I have an option in the repair (Vista disc) to load drivers, but what file is it that I use to load the drivers?

Any suggestions on how I can recover this HDD? While losing my data won't stop the world, I have about 2 years worth of articles I wrote that I don't want to lose along with my COD WAW profile lol, (not to mention some kick ass recipes I found over the last 18 month's lol). Besides, I'm hard headed and sick to death of the Microsoft typical "Reformat and re-install" method of fixing any minor OS problem. That's not a solution, that's dropping a nuke to get rids of a fly that's bothering you, sure the fly is gone but.............

I was uninstalling some things I didnt use on my computer and when it restarted it said that there was no os avaiable to boot to. I rebooted into f11, f10, f9, ever f- I could but couldnt move my cursor once I was in and had to exit. I ran all the self tests and it passes all of them. I bought it from a friend about six months ago. It came with windows 7 but i put windows 10 on it. I tried to restore and that didnt work either. I cant use a recovery disk because i have no disk drive. I tried to dl a new os but am having trouble getting it from my android to a broken computer. I'm trying to figure out a way to put it on a flash drive and maybe boot up with the flash drive because I have a flash drive of Kali Linux and it boots up fine with the computer. But I don't want to do that every time I want windows as my main OS. It be great if somebody could put me in the right direction because I feel like I've tried everything except the obvious. Thank you

is there anyway that it can be fixed without the operating system disk. I would be gratefull of any help.. thanks.. :D

A:''missing operating system'' ???

Sadly, the only way to fix this is though a installation disk or a recovery disk. Also, some manufactures sell a recovery disk for ~25 USD. this does depend on the manufacturer of your PC (dell, HP, and the like)

Also, is this a duel-boot, or just two PCs (under your name it lists XP and Vista)

We need that information because troubleshooting steps are different for the various Windows OSs.IF it's running Win10, did it come with that preinstalled?  If not, what was the prior OS of the machine and how long ago did you do the Win10 Upgrade?  And, was your machine OK after the Upgrade or were you having problems, and if so, what were those problems? We can proceed once you provide the information.Thanks

I have a Dell Inspirion desktop. About 10 days ago I installed Windows 7 on this computer. Everything has been working fine, did all the Windows updates. Today I turned the computer on an it says "Missing Operating System".
Before I installed Windows 7, I ran the Windows 7 Upgrade Advisor. I met all requirements. Also ran the compatibility wizard.
After installing Windows 7, I have rebooted the computer dozens of times after updating.
I'm hoping someone could help me this problem. I'm trying to avoid reinstalling Windows 7 again. But if I need to reinstall Windows 7 again that's not a problem.

You can boot up from your Windows media (dvd?) and go to the repair options on the 2nd page.
From there, you can do an automatic startup repair which will hopefully repair your machine.

Please i have very important data on desktop & i need that any how

Hope anyone out here help me out

A:Missing Operating System :(

Boot into BIOS setup to see if the hard drive is detected at all under Storage drives or in the Boot order. If not you'll need to try reinstalling it to see if you can get it to be detected. If it can't be detected you'll need to replace it.

Reset BIOS to defaults to see if you can boot a disk: How to Boot A Computer from CD or DVD - YouTube

Once you can boot a disk you can try to rescue your data using Copy & Paste - in Windows Recovery Console from the Windows disk to another hard drive, external drive or flash stick. If you have all three you can try writing the Win7 installation media to flash stick to see if it will boot, but you must copy your data out to external then.

Once you can boot the disk you can also access System Recovery Options to run Startup Repair - Run 3 Separate Times.

If these fail then everything else that can be done to start Win7 including hardware tests to confirm the hardware status is in Troubleshooting Windows 7 Failure to Start leading up to if necessary rescuiing your data to reinstall.

If the OS was installed where is it? It does not matter whether or not you can burn a CD, you can even borrow one; you need a key number and that will cost $150 for an upgraded DVD and more for a full version. There may be a key on the computer, take a look

Hi all,

I got a blue screen error message saying "memory dump". Now when I start my computer it says "missing operating system".
1. I tried to reinstall Windows 7/64 bit with my installation disk. Didn't work.
2. Tried to use a system restore disk that I made when the computer was new. Didn't work.
3.Tried to boot up from an old HD with windows on it. No luck
4. Tried to boot up in the safe mode. Got the same error message.

What more can I do to recover my missing operating system?
How does a computer "lose" an operating system?

Thanks for your help,

A:Missing OPERATING system

That sounds like either hard drive corruption or end of hard drive. Can you boot to safe mode? Or better yet "Repair My Computer". From there you can run "chkdsk /r" from cmd prompt which is available but make sure it points to "c" drive first.
To help more we need to know make and model of laptop or desktop.

A:Missing operating system

Boss2019, Sorry to hear your having this issue. Unfortunately when a machine starts stating "Missing Operating System" it usually means HDD failure. The only way to fix this is replacing the hard drive and reimaging the machine.

Hey all so I just picked up a machine. When I initially turned it on I got "Missing Operating System" I was able to run the Win 7 Recovery CD and fix the MBR allowing me to log in to windows. However, when I log in there are no desktop icons and the start menu is empty. I cannot access task manager either by right clicking task bar (greyed out) or hitting ctrl-alt-del (doesnt even show up)I dealt with this a while ago and it was easier to just backup the data using Sata to USB adapter and reimaging the machine. I was able to update and run Malware bytes and the scan came back clean. I also installed and ran AVG (free) with latest definitions again clean. I ran Kaspersky on the drive while it was slaved from my pc and it said there was one infected file but of course my license expired last week so no resolution haha.

Anyways, Im under the impression this is a rootkit and can be cleaned. When the drive is slaved I can see the data. I dont want to back everything up and do a restore and run the risk of restoring the virus. I am gonna try RKill and security essentials to see if I can make any headway.

Its an HP Tower running 32 bit Win 7. Nothing fancy. Dual core processor couple gigs of ram. Any suggestions would be much appreciated.

Hello, run these 2 if needed to get them back.Pease download the following program to your desktop:Unhide.exe Once the program has been downloaded, double-click on the Unhide.exe icon on your desktop and allow the program to run. This program will remove the +H, or hidden, attribute from all the files on your hard drives. If there are any files that were purposely hidden by you, you will need to hide them again after this tool is run.ORRun SFC,System File Checker

A week ago I turned on my computer, it started booting up and I got the message "Missing operating system." I used level 2 of Spinrite 6, which seemed to work fine but did not solve the problem. Using my Windows 7 installation disk, I got to the command prompt X:\sources and then did the following:
The volume does not contain a recognized file system.
The volume does not contain a recognized file system.
select disk 0

Partition ### Type Size Offset
Partion 1 Primary 100mb 1024kb
Partion 2 Primary 223mb 101mb
select vol c
Volume 1 is selected volume
Detail part
Volume ### Ltr Label Fs Type Size Status Info
Volume 1 C Raw Partition 100mb Healthy
ditto for selecting volume d to get the following:

Volume 2 D Raw Partition 223gb Healthy

Suggestions would be appreciated. I do not have a backup of the SSD drive. While it would not be a major disaster if I had to reformat the drive and do a clean install, I'd prefer making a good effort to recover the data. I have limited computer knowledge. Thanks.

Your partitions are showing up as Raw, it may be too late, but you could try a Live version of Linux.

My personal favorie Zorin OS - Home

Or try this

Hi there,

I am getting this message on my laptop that tells me "operating system is missing". This is supposedly to do with my hard drive either being broken, or the black cable connecting it is damaged! I opened up the computer and while the cable looks in tact, it has a bit of fraying at the end that connects to the motherboard, so what I would appreciate some help with is what I should do next. I would rather not seek a PC repair company because chances are I can fix the computer myself!

Hey there,
i've a feeling i'm in a fair bit o' trouble here so any help or ideas are welcome....

I left my pc defragging last night only to come back to it later and found it had restarted with the words "Mising Operating System". It scans for boot record from the floppy then IDE 0 and says "OK", then it comes up with the "Missing Operating System" line.

My Drive is all 1 partition by the way, laziness stopped me from getting around to changing that.

Has anyone else been in this situaion and got it sorted out???

Please help me!!!!

By the way i'm using Win 2000 Pro and don't have an emergency repair disk....

A:Missing Operating System

If your luky...putting restore disk in....close it and starting comp will get that to boot to re-install. open your case and see if anything is still melting. Wait for someone who knows more than me to really do anything though. sounds like your comp is really jacked up -joe

upon starting my computer it informs me of a missing operating system, my system is a dell xps, I have no system image disks. I have purchased a recovery usb from dell, now that does not work. I have also tried a system repair disk and that lists no operating system. I have no idea of what drivers to load and from where.

Hi and welcome to SevenForums,
This recommended update has been causing some problems


Not sure if secure boot would be affecting your machine or not but you might review your Bios and advanced boot options for secure boot.
Post some images if you want for the options you show.

i tried to put the recover stuff onto the discs and i was on the first one when my computer crashed so i had to turn it off wilst it was in the middle of it and when i try to turn i on i just get issing operating system on the screen

A:missing operating system

Hi. . .

The recovery DVDs must be burned per the manufacturer's instructions so they are bootable discs.

Also, make sure that your BIOS settings place the DVD drive 1st in boot-up order.

You should have a manufacturer recovery partition on your system - the majority of Vista Systems do.

Regards. . .

Ran Ccleaner last night on windows 7 64 and everything was fine. Then this morning when the computer re-started, it says missing operating system and windows will not start or read any discs. checked to make sure CD was 1st in the boot menu. And I am currently running diagnostics on my hard drive. So far everything is passing.

A:Missing Operating System?

When you used CCleaner, did you use the registry cleaner portion of the app?

If your drive passes diagnostics, I would try to do a System Restore to a time prior to using CCleaner--which I think you can access from a Windows install disc, if you cannot boot at all.

Hi, you could have a bad/failing hard drive. If it's a spinner drive you can run a test on it.

Pick one for your HDD brand or use Seatools.

A:Missing operating system

You need to tell us what kind of notebook it is. Model number. Also Windows version. A good guess is that your hard drive has gone bad and needs to be replaced.
