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.

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.

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.

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, 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:
http://www.dellcommunity.com/support...d=210868#M9617

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?

Thx
 

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?

This issue may occur if one or more of the following conditions are true:

* The basic input/output system (BIOS) does not detect the hard disk.
* The hard disk is damaged.
* Sector 0 of the physical hard disk drive has an incorrect or malformed master boot record (MBR).

Note Some third-party programs or disk corruption can damage an MBR.
* An incompatible partition is marked as Active.

Brand new Vista 32 bit Business computer - just 2 weeks old. Tried to partition C: drive (using Acronis Disk Director Suite). On first reboot, gave dos message "Missing operating system".

Went into bios, tried loading failsafe defaults - no success. Having googled on this, I came to the conclusion that I needed to boot from my Vista installation disc to do a Windows Repair etc. I tried to do this (having set this boot option in bios), but when it gets to the Press Any Key to Boot from CD bit, the error message "Missing Operating System" comes up again.

At this stage I am not too concerned if I lose what little data is on the C: drive (though it would be nice to think I could still recover it) - more concerned to just get Vista up and running without having to buy a new HDD.

Help! Where do I go from here?

A:Missing operating system

It looks like you either formatted the wrong partition, or formatted the entire drive. This message is shown when there is no operating system, or if the master boot record is corrupt.

Do you have your Vista installation disc? A Startup Repair should fix the MBR situation if that's all that went wrong.

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.

@xsailor please do not hijack someone else's thread. Please start your own thread, as your issues are different then the OP's
Usually when it says Missing OS that means that the HDD has failed. On another computer download the ISO image for Seatools in my signature. Burn the image to CD using IMGBurn also in my signature and boot off of the newly created CD and run the short and long tests on the HDD. If either test fails the HDD needs to be replaced.

Can anyone help me with a real problem i've encountered with an old p.c

I had to reinstall windows XP home edition on a friends p.c that had completely frozen up.
This was sucessful and i loaded all the security gear back on, did all the p.c maintenance (defrag etc). I found that there was no sound on windows media player. Having acertained through the troubleshooter that the drivers were working properly, a friend said i should check the bios and see if the sound card was still switched on.

Having necer done anything like this before he said i should press delete on boot up and that would take me to the bios screen. This i did, i found that the soundcard was switched on so tried to exit but had to press N in the save changes box to escape.

Since that i have not been able to boot the system up. It flashes the p.c info (american trends etc) then i get a black screen sayin "Missing operating system" when this appears the hard drive light goes out and the only way i can get out of it is to press Ctl-alt-del or switch the tower off which restarts on its own and tries to boot up again.

I have been back into this bios page to see if there was a restore defaults button but there are only F buttons for optimum settings etc.

this appears to be a non standard build p.c all i can tell you is that it was built in 2001, has a AMD athelon 2.0 processor, 256mb ram and 60Gb hard drive also has 350amp P/S

Any help or clues as what to do next would be most welcome

A:missing operating system

Welcome to TSF

The "Missing Operating System" (white "DOS" text on black screen, top
left) is usually from BIOS when it can't find anything to boot.

Can be due to:
- HD is defective or corrupted
- HD is not selected as a boot device
- a non-bootable disk is found before the HD in the boot order

Try this:
- insert your Vista DVD
- allow the "press a key to boot DVD" prompt to go by
- does Vista boot?

If Vista boots this way, then it's most likely the HD isn't in the
boot order, or there may be something wrong with the Master Boot
Record (MBR) code.

Is the system still under warranty? Find the manufacturer of your hard drive and run their Hard Drive Diagnostics Utility. Or there may be diagnostic utility already on a partition on the drive. Press F12 to see if there is a utility to use.

Ran Ccleaner last night on windows 7 64 and everything was fine.

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.

I have no idea what the history of it is or what the issue is, but I know that when I start it up, it says the OS is missing. I put in an XP disc to try to reformat it and reinstall XP, but after loading everything up, when it says it's loading XP to go to the screen where you can reformat or repair Windows and stuff, it just goes to a BSOD saying something about partmgr.sys.

I was wondering what the issue is here and if it's possible for me to reformat this drive and use it again or if I would need to buy a new one.

Thanks in advance.
 

A:Missing Operating System

If you have data that is valuable, don't do anything hasty.

There is a chance that the HDD is faulty, which means that your data may not be recoverable, but in hope that it is, I would recommend removing the HDD and connecting it as a slave drive to another PC running XP (or 2000) using an adapter. Then trying to recover the data.

Anything you do with the HDD in the laptop is high risk to your data.

As any HDD is one of the most failure prone devices in a PC, having valuable data that is not backed up is never a good idea, under any circumstances.

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)

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.............

After turning my computer back on I got a "Missing Operating System" message. I managed to fix the problem by using Repair from the install disc. Now I'm just wondering why it happened. The only explanation I can think of is that it had something to do with my external hard drive. I left it plugged in when I turned the system off. The reason I suspect the external hard drive is because I read about someone else who had a similar problem due to their USB ReadyBoost thumb drive. But does anyone know exactly why this happens?

Sounds to me like the harddrive is dead/dying. I would suggest performing a repair install with your Windows CD (if possible).

hi all,
I had asus p5kpl-am/ps mother board with windows 7 installed in it.
I tried to install windows 8 using an USB. The installation is almost over. at that time there was power cut which interrupted the installation. When I started the system again it is showing "missing operating system".
when I tried to boot from usb by pressing F8 to install the OS again, It is again showing the same error instead of starting the installation. please help me in soling this.
thanks.

does the USB Drive still work ? it maybe corrupted - have you tried going into the PC bios/setup - it will tell you as it starts what key to use - often F2 or F10 or Delkey
and check the boot order, make sure its set for USB

A:Missing Operating System

for the harddrive capacitys quoted can we assume that means remaining free space? If I were you I would put a new high capacity harddrive in and reload XP then use one or the other as a slave drive or use them as external usb connected backup drives.

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

Hi,
 
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.
 
Thanks,
Mike

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.
