missing operating system, del key does not work going to bios setting

Question: missing operating system, del key does not work going to bios setting

I was trying to recover/reinstall win 7 and bring back my asus laptop to its manufacture state. When I run the recovery media (recovery dvd) that comes with my asus laptop and after answering the prompts, it gives off "missing operating system" message on an entirely black screen. I tried to go to the bios setting by hitting delete key upon boot-up but it does not respond. I switched off and back on several times trying the delete key every time but to no avail. Please help. It's an ASUS N61J Series with intel i7. I need this very badly! Thanks...

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

Answer: missing operating system, del key does not work going to bios setting

Welcome to Windows Seven Forums.

Have you tried using the computer's recovery partition as it sounds as though the recovery disc may be corrupted?

To use the recovery partition you need to start your computer and tap the F8 key then select the repair computer option from the advanced boot menu. Follow the prompts to format your drive and restore your computer to its factory state.

Hi, every time I start my laptop with a pen drive insert into the USB port I have: 'error missing operating system'.  I entered in the bios and I changed the order of UEFI Boot Order and Legacy Boot, because the USB  was first on the boot list.I save the SATA as a first but everytime I have the same problem because the USB returns first on the boot's list even if I saved the options before. So I need to start the laptop taking care that any pendrive is insert. How can I resolve this problem?Thank you.

HI guys,

I'm working on a computer with a RAID setup. It is 2 hard drives 500gb each showing up as 1tb in windows. Both drives show up in the bios but all of a sudden when trying ot start the computer I get a "Operating system is missing" error.

I'm trying to run a chkdsk form a win 7 64 bit disk and telling it to run on H; (system drive) but it says 'cannot open volume for direct access'.

The other drive, C: is just a recovery drive built into dell computer systems.

I tried using a boot cd and running mbrfix to no avail. Any ideas?
 

Answer:Solved: Missing Operating System - RAID Drive - Show up in BIOS

You need to provide a LOT more information; the information you provided is somewhat confused.

Two 500GB drives, showing up as one TB. Does this mean the drives are striped?

Where, exactly, is the drive you are calling C: and claiming is the recovery disk?

How, exactly, is each drive formatted and partitioned?

Is this hardware RAID or software RAID? If hardware, whose controller? If software, which?

Hiya,

Firstly I should say that I am primarily a mac user, and it is not my laptop I am posting about. Although I am reasonably knowledgable about Windows, I haven't used it since XP, about four years ago, and so am pretty rusty.

Basically, my girlfriends computer randomly turned off about a week ago, she assumed it was a dead battery, plugged it in, and then when it turned back on it wouldn't boot displaying error message: missing operating system.

As it is a Dell laptop it didn't come with any installation discs, and I totally forgot to even make a repair disc when we got the laptop. I managed to get hold of a Windows 7 Installation Disc and license key for Windows 7 Ultimate 64 bit through my university. I think the laptop was previously running Windows 7 Home Premium, but that's all I know, and I'm not entirely sure of that fact.

Anyway, burnt the .iso to disc and have tried to boot several times from DVD Drive. The laptop loads the files from the DVD fine, and gets as far as the "Starting Windows" screen, where it seems to get stuck for a few minutes, until it becomes a black screen with just a cursor (the cursor still moves). This also happens with an 64 bit repair DVD I also managed to get hold of.

Any ideas on what I should or can do next?

Thanks

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
 

Answer: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?

I have Ubuntu 5.04 and Windows XP Media Center standard with sp2 (shouldn't make a difference though) installed on two different partitions. Mainly I use WIndows since when I decide to go play a game or play media files (on my xp partition) I don't have to reboot and reselect. The problem is by default Ubuntu starts up since it is at the top of the list. Normally I'd just go My Computer>Properties>Advanced>Settings for something on there (I forgot) and change the default, but it seems that only works with other Windows operating systems. How can I change this? It drives me crazy


Additional problem: My USB keyboard(s) never work in DOS and BIOS, only PS2 works. In BIOS I have USB support and USB 2.0 enabled, but it still does not work. USB to PS2 adapters don't help either. Oh, I have Award BIOS by the way.

Answer:Missing Operating system

what are the specs of the pc in question? Are you trying to boot from a scsi drive or external controller? If so, chances are you needed to hit the magical f6 key during the first stages of setup to provide the correct driver.

or, check the bios and make sure it's set to boot from the correct hard drive, and also make sure that the partition on that drive is marked active, otherwise the system won't boot from it.

Recently my aged Sony laptop decided not to work and on trying to boot produces the error message 'Missing Operating System'. All my recovery floppies accumulated over the years require access to the hard disc but this I dont have any more. Drive C is treated as a non-existant drive. But I think Format will access it but dont want to have to re-format the disc if avoidable.My basic problem is how to bridge the gap between what I can do with the A drive and getting into other drives (HD & CD-ROM) and this problem may still exist if I manage to reformat??On my Sony the floppy drive and the CD-ROM are exchangeable units.Thank you anybody in advance

Nothing was changed but it seems like when I was at work today my computer rebooted perhaps to finish installing windows updates?

Restarting it did nothing, I unplugged my 2 drives in raid 0/1 (not the bootup drive, crucial m4 is bootup win 7) still nothing, so I moved the drive to a different SATA connection and it booted up and said windows didn't shut down properly, I did safe mode then restarted normally just fine...and extremely fast of course.

So my 2 questions are why might this have happened? I'm going to do a couple virus / spyware scans but I didn't change anything at all.

The 2nd question is...how do I get into setup? I couldn't enter bios setup / boot menu no matter how often and when I pressed del / f11 keys to enter like the bios screen says...issue being there isn't a delay for it to register I believe. Do I have to reset bios to remove the overclock to be able to register the button pressing to enter bios since it boots too fast?

well, it was going to be gone anyway when you tried to reformat, so the only way i would try to fix the situation is to reformat and reinstall windows fully this time and yes, lose all your data. or, you can spend the money to get the data professionally restored, and that's not even a guaranteed thing.

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!

Last night, i let my PC on to run a disk defragment and when i woke up i realized that it was crashed, my monitor was on but i couldn't see anything on the screen so i restarted the PC.

Then i got the error Missing Operating System.
I accessed the BIOS and i noticed that the Primary IDE Master/Slave were not detected.
Then i inserted the Windows 7 disk to perform a repair and it didn't detect any operating systems. I clicked on Load Drivers but i couldn't access any of the drivers and it asked me to perform a format.

I've also attached some pictures of the screen to help you understand the problem.

Any help appreciated.

Answer:Missing Operating System

Welcome vpro

It looks like disk defrag may have wiped your bootable OS. It looks like your bios only shows you have 2 SATA HD connected to the MB. If you do not have any IDE HDs, that is why Primary Master/Slave were not detected. Normally the Bootable SATA HD should be on the first SATA connection on the MB. Your 5th pic, in the background says (4) Hard Disk Drives ? Could you please give a few more details of your hardware specs ? How much data & programs were on your Boot HD ?

My brother wants me to fix this laptop that he got from someone awhile ago. 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.

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

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.

Help me please.

Hi

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.

Any ideas? Hoping my drive is not dead :/

Thanks

Had it been running OK before? If so, try to think of anything different you might have done just before the problem occurs. It feels like there's some info missing here...

Answer: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.

I apologise if this is the incorrect place to post my question (first time using the forums)
I have a Dell Inspiron 3646, Intel(R) Celeron(R) CPU J1800 2.41 GHz 500GB SATA Hard Disk Drive
I was attempting to boot Linux from a live USB.
The previous OS was Windows 8, no recovery disk was supplied with the computer.
I entered the BIOS menu to change the boot order from the HDD to the USB.
Before I changed the boot order, I changed the Boot Mode from UEFI to Legacy.
(I was following instructions on the internet and mistook this as the boot order.)
I didn't change this back before I continued and can't remember if the default setting was Legacy or UEFI.
I booted from the live USB and continued to try and install the ISO of Linux onto my HDD.
The install encountered an error and took me to a shell.
I exited the shell and rebooted without the USB.
I now receive the following error message
"No boot device available
SATA 0: Installed
SATA 1: Installed
Strike the F1 key to retry boot, F2 to run the setup utility"
The above error message is repeated on reboot.
F2 takes me back to the BIOS menu.
I have run the Dell pre-boot diagnostics and all tests were passed.
From my internet searches I understand that I may have corrupted the boot loader that was on the HDD.

IS THERE A WAY FOR ME TO REPAIR THE HARD DRIVE?

I would greatly appreciate any help, guidance or advice on the above issue.

Please let me know if you require any further information in order to be able to ... Read more

Answer:Missing operating System

1. welcome to Tech Support Guy
2. Sorry you have waited a few days for a reply
3. If the computer came with Windows 8 pre-installed then it is most certainly a UEFI boot mode and windows 8 or now 8.1, I presume would be installed on the hard drive in GPT format
4. The boot configuration data for windows would actually involve the booting from a partition titled windows boot manager, this would then hand control to to Windows to complete the of windows
5. It is more or less impossible to decide what you have done, as there is no way of knowing where you installed or attempted to install the Linux based system
6. Your first approach if you have not already done so is to return the boot mode to UEFI in the firmware. Save changes and exit
Shut down
Now when you power on select the boot menu and ascertain if you have an option of windows boot manager
7. The no boot device available is because either - you have attempted to install Linux by selecting the wrong partition or space in which to install it
OR due to the legacy mode when the firmware is looking for the wrong boot loader
OR indeed you have formatted the partition from which windows 8.1 would boot.
8. If the resetting of the firmware to UEFI mode does not achieve anything then you are going no further until you have either the Windows 8.1 installation media for your version - eg 8.1 Professional or Home, the bit version 32 or 64 and the language
You make that from here

Answer:missing operating system

If you had backed up your data, or cloned the HDD before attempting any repairs you may have come through this unscathed. However, the only way you will be able to pluck your data at this point would be to install your OS on a new HDD, and connect your old drive externally or connect it to the motherboard alongside the new HDD if this is a desktop.

Cloning won't help, as apparently the OS corruption is too severe. Apps can't be copied unless the drive is a clone, and it appears you will have to start over from scratch.

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?

It seems one mystery just leads to another....

Our newest computer, DELL Optiplex 780m tower, Windows 7 Pro; after a minor glitch or two, this unit had been shut down and later started, and restarted, a number of times and all was running smoothly.

The only thing I changed, and I somehow don't really think that it has any bearing on the situation, is that, in the wee hours of last night, I installed Photoshop Elements 12.

Upon installing E12, I clicked the button that said "restart now"; the computer restarted without a hitch; I played around a bit with both sections of E12, the Editor and the Organizer, and then I shut the computer down for the night.

Then, this morning, I turn the computer on and it stops at a black screen with the message "operating system is missing"

It did not say anywhere to do this, but I pressed Ctl-Alt-Del, and it then proceeded to boot right up.

I thought this might just have been a freak occurrence, so I shut it down, waited a bit, and turned the power on again; it stopped at the same black "operating system is missing" screen; ctl-alt-del got it to start again.


History: this unit was new just days ago with a clean install of Windows 7 Pro.

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.

So, I have a toshiba satellite m55-s135 which was running a fully updated windows XP. However, after installing some virus scan software tonight I had to restart my computer. When I did this I was greeted with the following message: Missing Operating System. I have no doubt that this is due to a virus. I have tried booting from a windows XP disc but the process stops at the screen which says: Starting Windows. Windows never actually starts however. I have also tried booting from my toshiba recovery disk but am unable to do a partial recovery and rather it says I need to reformat my hard drive.

My Question is this: does anyone know of another way of reinstalling an OS other than reformatting? Or perhaps a way of regaining at least some of my data after I reformat? I know that wiping a hdd tends to still leave traces of data; is there a way to reclaim these bits?

Thanks for any help you can give.

I had a small virus on Dell XPS. Its about 8 months old with home edition. I did a system restore and a virus was hanging around about buying some virus scanner software...anyways. I did a restore and it was fine but the window kept popping up so I did another restore and I selected something different from the list. I was going fast and I obviously wasnt paying attention. I hit cancel after it started restoring the files and I believe it was warning me that I would lose my stuff if I continued. I hit cancel now I have the missing operating system error. Dell didnt send me a windows 7 cd. I was suppose to let them backup my files OL but Im not letting anybody have access to my puter. So I bought an eternal HD and backed up everything there.

First of all, system restore does not eliminate the virus. Second, copying infected data is not a good idea.  Last, I really don't understand what you're trying to do.If I were you, at this point I'd format the hd and start from scratch - and that's not a suggest I make often or lightly.

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?

Answer: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.

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

Hope anyone out here help me out

Answer: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.

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)

Answer: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.

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

Hi: You are going to have to download the W10 ISO file from another Windows PC using the Media Creation Tool below. https://www.microsoft.com/en-us/software-download/windows10 Then you need to use the ISO to DVD/USB tool to transfer the file to a USB flash drive. https://www.microsoft.com/en-us/download/windows-usb-dvd-download-tool The tool will make the flash drive bootable.

Answer:Missing Operating System

It sounds like you had an unfortunate re-partitioning incident.  The good news is that your data is seemingly still intact.  The bad news is that it looks like you are going to have to completely re-install your OS's.You've made a valiant effort so far in trying to repair your operating systems and it may still be possible, but I'm guessing you are going to need some fairly specialized help.  Now might be an excellent time for a harddrive upgrade.

For the 2nd time in three days, when I attempt to boot, I got the error message "Missing Operating System". When I first contacted Hewlett Packard, they told me that the MBR was missing or corrupted and that I would have to reinstall everything.

I did!

Now, two days latter, I get the same message ... from the computer and from Hewlett Packard.

I'm not sure what happened the first time, but the most recent occurance happened when I attempted to reboot to Vista after running a Linux Live CD (SimplyMepis). I did not install Linux, just ran it off the CD. I closed down Linux, took the CD out of the drive, and attempted to boot to Vista. Result "Missing Operating System".

I've checked the boot order in the BIOS and even changed it so that the hard drive booted first. This didn't work.

Does anyone have any idea how to fix this without a reinstall?

Does anyone have any idea as to the cause of the problem?

Does anyone have any idea how to avoid this in the future?

I sure need your help. Thanks.

Hi New to this forum, so go easy on me. I've recently bought a brand new U410 I7, 8GB, 1 TB in less that 1 month I have had to use the 1 key recovery to reinstall the OS about 4 times. Why ? each time I have ran windows updates & the unit restarts I get "missing operating system" Any ideas ?? Has anbody else experienced the same ?? many thanks  Dave

Answer:missing operating system

I suggest you do clean install of windows on your own. Might be a problem with the factory backup and os itself.

Hey there!

I have a Dell XPS 8300, and after being away for 10 days, I came back to my computer and saw Missing Operating System...

I've done everything, and all the symptoms are as same as yours (thorough checking says all disks are ok, cannot get C: drive to show up in MS DOS)...
How did you fix yours??

Thanks!

Jim

Answer:Missing operating system

@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.

Hi guys.  I have a Dell Dimension XPS/630i (less than a year old).  I'd give you more info, but I can't get it to boot up.  When I turn the computer on, it goes through the typical Windows loading screen then goes to a page that gives me a message that reads: Floppy Disk(s) fail (40).  I can then press F1 to continue or F2 to enter SETUP.  If I continue, I get another message that says "Missing operating system".  F2 takes me to Phoenix - AwardBIOS CMOS Setup Utility.  I cannot get into Windows at all and all of my stuff is in there.  My wife's business files are there too.  Does anyone know what I need to do now?  I need help.

Answer:Missing Operating SYStem

and welcome to the Forum

The drive may have failed . . You can run diagnostics on the hard drive by downloading the diagnostic tool for the hard drive brand and making a bootable disc.

Answer: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.

I have a Lenovo T500 Thinkpad.  I turned off my laptop and now when I turn on the laptop I receive a message that states "Missing operating system". I do not have any recovery disk or install disk.  How do I fix this error?  The only thing that I have been able to access is via the blue ThinkVantage key.  I receive a screen that has a Startup Interrupt Menu with three options.  ESC to resume normal startup, F1 to enter the BIOS Setup Utility or F12 to choose a temporary startup device.  I see the messages where the drives are partitioned and I should be able to set back to factory standards somehow, but I sure don't know how to even begin. Can anyone help me, as I am clueless.Thank you

I have a brand new Lenovo IdeaCentre desktop that came with Windows 7 Home Premium.  I added a dual monitor video card & drivers and then did a clean install of Windows 7 Professional.  When I tried to get on the internet to do all the updates for Windows & Norton, it wouldn't connect and gave me the message that my Network Adapter was missing.  So, that problem was solved very nicely on the Driver Forum of CH, and I got the proper driver and connected to the internet.  At that time I didn't do the updates, but shut the computer down and booted it up the next morning and all I got was a black screen with the words: No Operating System   I shut it down, waited a minute & started it up again, and again it said:  No Operating System.  I shut it down again, waited a minute, and then it started like nothing was wrong?? I proceeded to the internet and did downloads for 2 hours (Hughesnet is SLOW) and during that time the Windows downloads and installations required multiple re-starts and it was fine.  It ran all day yesterday and I shut it down last night and when I went to start it this morning, I got the:  Missing operating system message.  I tried shutting it down and restarting several times and nothing.  Even tried the old Control/Alt/Delete and that brought up:  PNY G-Force GT430 PCie, Version 70.08 2.0, Copyright Nvidia, then it went to the LENOVO name and then back to:  Missing oper...

Make sure the cables to your hard drive are firmly in place. Unplug them, plug them back in. Check the connection to the motherboard too.

Ok I was recently trying to do a BIOS update on my ASUS m2n32 Sli-deluxe motherboard and it said to set your BIOS settings to default before the update, so I restarted the computer and did that and then saved changes (I am running Vista 32 bit).  Well, the computer then went to reload and after the BIOS screen I am getting the message "missing operating system".  So, I restarted the machine and went into the BIOS to see if anything had changed and it is still detecting my hard drives and the boot order is still CD, HD, other and the message still comes up.  So i booted it with my recovery CD (i only have this from ASUS, not a full Vista disk) and i ran the startup repair even though it could not recognize an operating system and it came back with the response it could not fix the problem and these codes:Problem event name: Startup Repair V2Problem Signature 01: External MediaProblem Signature 02: 6.0.6000.16386.0.0.0.0Problem Signature 03: 5Problem Signature 04: 65537Problem Signature 05: unknownProblem Signature 06: corrupt partition tableProblem Signature 07: 0Problem Signature 08: 1Problem Signature 09: FixPartitionTableProblem Signature 10: 1168OS Version: 6.0.6000.2.0.It looks to me like the partition is corrupt but I am not sure, and I am not computer literate enough to know what to do next.  Any advice would be much appreciated, thank you in advance for the help.

Answer:it says missing operating system !

Well. You agreed to wipe the drive as part of the restoration process. the question we would ask is what prompted you to use the restore disks in the first place?The fact the format process failed at 18% may be an indicator of a faulty hard drive.You should download a hard drive diagnostic tool from the company that built the drive and run it from a bootable CD or floppy. If you do not know the make of drive in your system open up the case and look at the label on the drive.If the drive turns out OK then something else such as overheating or a motherboard fault may be contributing to your problem.Goin' Fishin' (Some day)

I am in need of help again. While I can usually troubleshoot almost any problem, there have been a few that have thrown me for a loop, and this is one of them.

Yesterday Microsoft released a number of updates for Windows Vista. I am running Windows Vista Ultimate 64 bit. Only 3 of the updates installed, although I couldn't tell you which ones. The system prompted me to restart and upon restart I get "missing operating system". I can't get to the boot selection screen to even try safe mode. I tried booting off of the DVD and doing a repair, only to find that my hard drive can't be found, or at least not the Windows installation on it. It's a SATA drive and the drive letter is able to be found when I tell it to look for drivers, although it says the file format is wrong. Microsoft tried to tell me it could be a bad hard drive. Yeah, could be, but it happened at the exact moment I restarted after installing their update. My thought is that it's a corrupted boot sector or boot loader. Any ideas, possible fixes?

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