Missing Operating System error on Acer PC

Q: Missing Operating System error on Acer PC

The lame recovery cd they provided only offers me the option to format and restore everything and lose all data on hard drive.

I would appreciate any ideas. Thanks.

Preferred Solution: Missing Operating System error on Acer PC

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.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I disabled the recovery in bios, and still nothing. I have no recovery disk, All I want is xp on it........Any thoughts????

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?

You need to boot the installation media and not the hard drive. Once booted use the Drive Options pictured in Steps 6 and 7 of Clean Install Windows 7 to delete all partitions, create and format new as you wish. Ignore the small boot partition it creates, install Win7 to first partition.

Ok its a bit of a long story, but Id really like some help!

I currently upgraded from Windows XP to Windows Vista Home Premium edition via their website. I downloaded the new operating system with the upgrade. I do NOT have it on disk. After about 2 days of running it, I turned my computer on first thing in the morning, and the error message came up saying "Missing Operating System". I have tried everything! I went and checked the BIOS settings and everything seemed normal. I have no idea what happened! I can't make any boot floppy's b/c my new Compaq doesn't come with a floppy. It won't let me go into the recovery console (F10) but it will let me go into Setup (F1). F5 and F8 options are not available as options either. If anyone knows what I can try to do, please let me know! Thank you!!!!!

I have a Dell Inspiron that won't start. It says it is missing its operating system.

Using the Windows 7 DVD that came with the machine I went through the repair Windows procedure 3 times. The first time it searched for restore points of which there are none because the machine has Rollback Rx installed instead. It then restarted with no change. I went through the same process but this time it said it had repaired Windows however; restarting gave me the same missing OS message. On the 3rd attempt it displayed the restored OS as being on D:\. I ran the diagnostic tool and it said no errors were found. Restarting gave the same error.

How can I get the machine to boot from D:\ or move the OS back to C:\ please?

How did that happened? Did you format your hard drive or something? How many drives do you have maybe its installed on another one.

If all else fails the only thing left to do is to do a system recovery or factory restore, if you are looking for a clean start then follow this guide: Clean Reinstall - Factory OEM Windows 7

My computer was built by my friend and we've had it for 3 years without problems. I have Windows Vista Home Premium, with service pack 1 and updates installed. I generally use Firefox but have IE installed also.

About 3 months ago the screen would go black (and even purple once,) sometimes when I was watching a movie. The sound would still play, but screen would go black, so I had to shut it off manually. At some point, one day I turned it on and instead of going to the Windows log-on screen, it went to a black screen on startup that said: Missing Operating System. We wiped the C drive and re-installed Windows and all my programs.

It seemed fine for a month, but then I started to get error messages and web-pages freezing again. We dusted out the computer and installed some updated drivers for our video card, and a week went by and I thought we were in the clear. But nope, the error messages and freezing started up again.

Here is what happens: When I have a few Firefox windows open and then go to close one or two of them, the computer freezes and then I get several error messages that are all similar but with different application error names.

How can I resolve this problem?Thank you.

Hi all,

Installed a DVDRW drive but comp crashed when installing some software and it stopped detecting my Primary Master and Slave drives. I've fiddled about with the Master and Slave configs and have managed to get it to detect my HD and DVDROM.

I've unplugged my DVDRW and my small HDD and am trying to get windows to load up.

After using FDISK /MBR an rebooting, I get "Missing Operating System".

Tried installing Windows XP after formatting, it seems to have installed but it's not loading.

Current config:

Slave: Pioneer DVDROM (not the DVDRW)
Master: Seagate 80GB (C: = 15GB) & (D: = 61GB).

D: has files on there that I'd like to recover. Too big to put on floppy.

I've run a search for similar problems and tried some of the solutions but no good. Any ideas? Thanks

For reference: Acer Aspire v15 Nitro running Windows 8.1

I made a mistake. A friend gave me a USB drive and I wanted to format it, but the USB was actually broken and didn't show up. What I thought was the USB was a drive with a name containing the word "Pushbutton". I formatted it and the computer ran fine until I restarted it. Upon restart, I am getting the error:

"Missing operating system.
No bootable device -- insert boot disk and press any key"

I've been working on this problem for a little while and at first suspected I messed up the MBR. I loaded the windows 8 startup disk on a USB and ran various repairs to no avail (including bootrec stuff in the command prompt).

I have no idea what I did. I know all of my files are still in there somewhere. I didn't do anything to the main disk or partition. I think I formatted some kind of partition that is related to booting up the OS.

I'm not sure if this changes anything, but my hard drive is full disk encrypted using VeraCrypt.

A:Error: "Missing operating system. No bootable device"

I don't know about VeraCrypt, but with MS encryption, you need an extra BOOT partition that is not encrypted. Perhaps that is what got clobbered.

If you have access to another working PC, then you should download the Minitool Partition Wizard Boot CD and make a CD or USB stick from it. To make a USB stick, you'll also need to download RUFUS and use that.

Once you have that, boot your machine and see what partitions are on the drive.

Hey folks, thanks a ton in advance for any help or suggestions given. I guess my old account was deleted, but I previously joined/donated for some help received. Regardless, I have a friends Acer laptop I am attempting to help her restore as usable. Acer Aspire 6930Intel Core 2 Duo Processor T5800 (2.0GHz, 800MHz FSB, 2 MB L2 cache)1244MB Mobile Graphics Accelerator 4500MHD3 GB DDR2320GB HDDWindows VistaWhen you boot it, it pretty much stays in the boot screen.....does no more. She got the computer from Best Buy, and they set up 3 recover disks. When you try to run the 1st of 3, I select the language....then a prompt comes up to ask me what I want to do. As you can see below, I cannot select "restore from backup". I then click to "restore to default" and then I get this error message......I searched the error message, and found others who've experienced the exact same issue. What they discovered is that the computer would not utilize the recovery disks if there was an existing partition. So the folks with the same problem as I, downloaded the Ultimate Boot Disk to recover their computers. When I do that, I got a message in BIOS saying "No operating system found".This whole message....I can follow directions very well, and I am a fairly familiar with computers....but not enough to solve this one. I appreciate anyones time thrown in to try and find a fix or a final resolution (if the HD is fubar). Darren

I have and Acer Aspire One that has a big problem. This is my 12 year old daughter's computer. She got it for Christmas in 2011. By June 2012 it was really slow and bogged down due to cookies and any other number of things she had going on. A friend was over and tried to do a system restore to get it back to factory settings. In the middle of the restore the computer shut off because the battery died. Our luck that it wasn't plugged in. When you turn it on now it just goes to a black screen and does nothing. I have taken it to box stores with so called technical support and was told that we had to get a new operating system. I don't want to pay more for an operating system than the computer itself. So I just went to purchase another one. As I was putting it in lay-a-way the check out guy said that I could just down load a free operating system and install it. That I could use the product key that is on the computer already. I get by with computers but don't know where I could find it to download and make sure I got the right one and that I was doing it right. It seems like something I could do with just a little guidance. I know that it came with Windows 7 Starter.

Any help that you could give me would be very appreciated.

If you need more from me let me know and I will try my best to get you the info.


A:Acer Aspire One Operating System Issues


You definitely do NOT need to purchase a new operating system.

You can legitimately download a Windows 7 ISO, burn it to a DVD, install it and then activate it using the product key on the COA sticker affixed beneath the laptop.

Follow the instructions here to do that - it provides a link to download the Windows 7 ISO, and all the steps you need to perform. Read it thoroughly before starting.

If your daughter still has files on this computer that haven't been backed-up, then use this to copy them off the laptop before re installing Windows 7.

A:Acer Laptop wont start operating system now!!!!

Aparently you have tried to make the laptop as dry as possible, but things can still be fried inside it. I am afraid the latter is the case and that you will have to opt for a waranty claim, although water damage usually isn't covered in that.

To recover the data I suggest to remove the harddisk and put it in or connect it to another laptop... but bottomline is that I think your laptop is lost :-(

I am using the Acer eRecovery option to recover Windows 7 operating system. However when it reaches point of installing Office 2010 it freezes and does not move forward. Wanted to know if there is a way to get past this , even if I can bypass the Office 2010 install and complete the Windows OS install.

A:Acer eRecovery management for recovering operating system

I don't know if there is a way to get past the stalling, but you should be able to do a clean install of Windows 7 without using the eRecovery partition if you have a valid Certificate of Authenticity sticker containing a 25 character Product Key.

You'd end up with a fresh Windows installation without any of the other stuff Acer may have included--no Office, no extra stuff. Just Windows 7.

You'd need to download a Windows 7 ISO and burn it to a DVD or get it onto a USB thumb drive if you don't have a DVD burner.

Hi guys.

I will apologise now i really am a noob here ive done a lot of researching on forums and found some great help so full respect for all you guys you really do know your stuff.

I have recently purchased an Acer Aspire Z5610 it is a second user buy.

Straight away i noticed that it just wasnt working right which is half to be expected im sure when buying second user equipment.

After doing some research on forums i came to the conclusion of erasing the C drive and reloading the OS with the system restore disc i created on the computer.

I was getting all the way through and it was failing and suggested that there was a fault on the memory disc. Ive managed to get into the back of the computer and removed the RAM sticks and tried loading with just 1 and with both and all the different combinations of being in different ports.

Now it gets to 2% and just stops loading altogether its just sticks at wherever its stopped.

Im lost for answers now which is why i have decided to post.

Can anybody offer any suggestions please?

Many thanks in advance.

I just upgraded from Vista Home Premium to Win7 professional x64 hoping to fix the above mentioned problem. After a complete re-install Im getting the same errors.

Im not sure of the proper terminology here, but during startup the computer does a scan of all hardware and "Volume 0" has a "failed" message.

The odd thing is that sometimes after a few restarts and pointless boot menu visits the computer starts up fine.

I tried windows repair feature by booting from the disk, but when I get to the window where i select the operating system to repair, its empty. Drive C, where the operating system is, is not showing.

I have a feeling that the hard drive itself has gone bad and is very unstable. Please let me know if I'm missing something or we just need to get a new HD.

Thank you

A:Win7 pro startup error "Boot MGR missing"/"Operating System Not Found

What type of hdd do you have. For example if you have a Seagate drive, there is software you can run to do a diagonostic on the hdd before the operating system boots.
This would be a good idea, especially if you were having same issues when Vista Home Premium was installed first.

Do you have more than one hdd installed. If yes, make sure in BIOS settings, the proper drive is selected for First Boot. And better yet make sure its the only drive attached when booting.

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.

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.

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?

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
