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.

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?

You should have run chkdsk, not a virus scanner.

Answer: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 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."

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

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.

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.

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?

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.

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:
c:
The volume does not contain a recognized file system.
d:
The volume does not contain a recognized file system.
diskpart
select disk 0

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.

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.

Hey,

Turned my laptop on last night (sony vaio with windows XP), it got into windows and then just re-started before it had booted properly.

When it started second time i got a message saying 'missing operating system' and i couldn't get into it.

I've got a lot of photos i dont want to lose and stupidly havn't backed up so i was panicking!!

I turned it on about an hour later and it started into windows and i managed to copy photos off onto a usb pen drive. So now i'm REALLY confused. Obviously something is wrong. What next steps should I take??

How did you fix yours??

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.

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 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.

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.

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. I plugged into my laptop to check and everythings there. Heres the ? How the F do I restore from my external HD if missing my software?.......

Answer:Operating system missing

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.

so about an hour later, i turn i back on and it works like normal! that's odd. so when it was night time, i figured i would turn it off since i didn't think it was going to happen again. wrong.

next morning i turned on the pc, and same error again, so i checked into bios and on my primary master, it has something else listed on there. I don't remember.

so i restarted and went into BIOS again, except not my hard drive is being listed so i continued to load up and what do u know...it works normal..

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.

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

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.

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 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?

Hello

This is my first post on the forum so excuse me if i make any mistakes

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.

Thanks

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 ?

I have had a long 16 hour work day, already so I don't want to advise you what do do yet without more info & hopefully some more of our Guru members will see your thread also.

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.

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.

Answer: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.

I was getting the above message. Now I get Error Loading Operating System. I was going to re-install WinXP but got scared when it asked me to choose a partion and I would lose all data. I have tons of pics on there that I don't want to lose.

It's an HP Notebook with XP Home installed but i can't find my CD. I do have a CD from a dead computer that is XP Pro. Will it matter? I also have the HP Recovery disc. Should I use that instead? It's a set of 6 cds.

Thanks in advance.
 

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.

Answer:Help! --- -- missing operating system?!?

Get into rescue and recovery somehow ,, either use an old disc with "start up" or try pressing "F8"  a zillion times from the "off' mode   in other words get into rescue and recovery  ,, once in  "retry" the restore to factory settings or if not try a restore from any back up of any kind,, then once even a partial system is in get back into rescue and recovery ,, do a complete hardware check,,,,,,, if all comes back good or rotten,, try factory restore again,, keep trying it and trying it ,,, be prepared for a very long affair......  One word of advice                                          maybe 2                                     1..  sometimes in "restore to factory" settings,, the chip that holds the image of the original install ,, sometimes is or gets corrupt,, "DO NOT PANIC"  let it cancel close down etc,,,   restart to rescue and recovery,, re try ,, same thing again,, re try,, same thing again, re try,,,,,  Actually what it is doing is "repairing and installing " the factory recovery install drivers from the chip,,,, eventually&nbs...

Hi allI used Active Kill Disk to delete the hard drive on Windows XP.I assumed inserting a CD Rom or DVD Rom containing XP again would auto re-load and install?Message says "error loading operating system,"any ideas please?Thanks....Neil.

Is BIOS set to boot first from CD Rom, as it may be looking at the Hard drive for a OS. Where it should be Boot Order in BIOS CD Rom as First Boot followed by Hard Drive as second

Hi!I have a un IBM thinkPad T 60. When I press thinkVantage button during boot up, the Predesktop Area doesn't load. There's only "Missing operating system" message displayed.I had before a message that I doesn?t understand but the computer copy on my external hard disk directory with name Preboot, MinNT et RRbackups.Some one understand what is not OK ? Thanks

Answer:T60 Missing operating system

cestvert welcome to the forums, If you have acess to another IBM/lenovo system you may want to repair the R&R program by pressing the F11 key or want to repair the MBR(if your service partition is still intact). follow this link and download the program for your appropriate OS  Important: For Windows Vista systems, do not save the file in C:\ directory. When prompted, select a drive and directory in which to save the downloaded file. Be sure to select a path that does not have a space in its name.

Gateway Solo 1200 Laptop - Win XP Pro - 850 mhz - 192 MB RAM

When I boot the computer the Gateway logo screen appears. At this point there are two options: ESC to boot from floppy or CD or F2 to change system settings. If I don't choose either of those, the next screen is black and says "Missing operating system". I tried using a boot disk but understand that there really isn't an XP boot disk. I think this computer originally had Win ME installed and was upgraded to XP. I tried using a Win ME boot disk... no luck. Any suggestions welcome. Thanks.

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.

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.

Answer: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 turned on my Dell Latitude Laptop which immediately displayed "missing operating system".

I restarted the computer and got the same message.
I restarted and pressed F12 for reboot options and ran diagnostics. All passed.
No other functions are available.

Is there a program I can download to a flash drive to boot up the computer to run a virus scan.

I am using Windows 10
 

Answer:Missing Operating System

Even the HDD diags passed too? Cause it sounds like no HDD is being detected. I'd you press f12 for boot options and select internal hard disk does it work? Does it give an error?

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.

Answer: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.

Hello, i have turned my pc on and it says 'missing operating system'

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

Answer:''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)

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.
Due to getting the error 0x80780119 when trying to create a system image, I used EasyBCD to relocate the boot manager to the C:\ drive after which on the next restart it said "bootmgr is missing"; I used my Windows system repair disc and it booted ... Read more
