Whenever System Boots It Asks To Choose Operating System
Nov 22, 2012
whenever i boot my pc i starts making sounds for like 15 secs and later asks me t choose my operating. this started wheni removed my battery for like 3 weeks and then inserted it back. am using acer mini.
I was playing Syndicate on PC, and then suddenly, the game froze along with the sound. I could not alt tab, or ctl alt del. So I shut down the laptop using the power button. Then onwards, every time I start/restart it beeps numerous times and then the HP logo is seen, then it beeps numerous times again and then asks "Choose operating system". I click windows 7 on that screen and then it starts and works fine. I have started and restarted, and the number of beep codes are numerous and dont have an exact count every time. On one start it might be 11 beeps and on another it might be 8 beeps. I am on HP G70 120, and I am on Windows 7 32 Bit. The only operating system I am using is Windows 7.
Suddenly my Win 7 Home Premium x64 will not boot. The system starts, POSTs then loads the DVD driver, then the screen goes black (not blank but "lit up" black if that makes sense). Then nothing. If I use Hiren's boot cd I can boot up using the "boot from HDD" option fine and Windows operates normally. System restore to a previous configuration made no difference to the original problem. I cannot boot into Safe Mode. F8 just offers me boot order options.
- Running the Windows 7 DVD I find: "No operating system is listed on the Repair Windows option." - Running Startup Repair finds the following error: "the partition table does not have a valid system partition" which it claims to have repaired, but the error remains and Windows will still not boot.
I followed this advice: Boot 7 dvd to system recovery options command prompt. Type: Diskpart list vol (find the vol letter e.g C or partition number e.g. 1 for the system partition ) Sel vol C ( or sel vol 1, obviously use the correct letter or number) act exi
My system partition was easily identified and listed as healthy so I selected it and made it active. The problem still remains exactly the same. My system is self built just over a year ago, to my knowledge has been running fine, without any hardware issues. I'm prepared to do a clean install if that's what it takes but if there is a way to fix the partition problem without that I'd like to explore it first.
"Missing operating system" massage is coming when i start my system and i am not able to start. I think because , i had given "mark partition as active" option for one hard dive (E) in disk management when last time i opened. it did not have any data. i did not know, this will make any problem. Now i am not able to boot windows re installation dvd also. i can only take BIOS settings.

I am looking to upgrade my desktop from an xp to 7. System builders are very cheap which concerns me. What is the difference from a system builder and the regular version.
I have Installed Windows 7 Ultimate x64 RTM 7600 and everytime i reboot my computer it asks for a system disk... I have to Put the Windows 7 disk in the dvd drive and reboot for it to load.. anybody know what may be causing this?
Also when i reboot i ahve to disable and re-enable my Network adapter in order to connect to the internet..
Ran F12 to regain Operating system - long version. Says computer passes everything but there's no operating system found. Did this Twice. Tried "Operating System" CD that came w/ Studio 17 laptop. Hit option to run via CD & never got anywhere after an hour. Tried Reinstall Hardware disk that came w/ laptop. It shows Vista, but laptop came w/ Windows 7. See where it shows the system's checking things out, but never get anywhere.
I tried a registry tweak to fix my home networking issues and came up with a major fail. Long story short, I changed the rpcedptmapper value and the system won't boot.I put the HDD in a cradle and it won't get recognized. HP in all their wisdom, sets the recovery disk to obliterate the entire HDD even if you created a separate boot partition
So lately my computer's firewall has decided to not work so I searched around and eventually concluded on doing a upgrade reinstall. As I didn't want to lose any of my files, drivers or programs. All seemed like it went well until the computer rebooted for the last time before it reaches the " Setting up for first use " dialog Though before this was able to happen the computer went into a reboot loop with bsod 0x0000001E
After a large amount of reluctant clicking The computer NOW only boots to the System Recovery Options window and the ONLY option is Startup Repair ; There is NO command prompt no diagnostics, nothing, Just Startup Repair, in which start up repair is unable to do anything and continues to loop itself with a Don't send dialog
I have tried inserting the installation disk and accessing the Repair Computer but it presents an incompatibility error.
I have no F8 menu at all, (no safe mode, which I can't access anyway because the computer can't set up for first use).
I have a HP dv9920us. A month ago I upgraded to win7 from vista. Everything was working fine until a couple of days ago when returning from work I found a black screen and an error message " no operating system found". No attention paid since I thought that my hdd went bad. So got a new one installed it but got the same message. So went into BIOS and saw that no hdd was detected. My laptop has 2 sata ports so I changed port and to my relive BIOS recognized my hdd in this 2nd port leading me to believe that the first port had gone bad. I did a clean win7 install. Everything went fine. Installed drivers etc no problem. During the first boot after and right after the post message the laptop just suddenly shut down and rebooted and then shut down again just after the post message. This loop went on for a couple of times and finally ended to a black screen with the message " no operating system found". Checked the BIOS again and the hdd was there. Booted the machine with the installation dvd in the drive this time and after the same loop for a couple of times (boot-post message- shut down- reboot ) instead of going to the no "operating system found" it continued and loaded win7. I've performed every possible test that I know for checking memory, hdd etc and everything looks good. The bottom line is that now the only way that I can use my laptop is to boot it with the installation disc in and it loads and works perfectly. If I try to boot it without the disc I end up with the "no operating system found".
I was just wondering is there anything within the fabric of your p.c. (the p.c. equivalent of a clothes label) which specifically states its operating system.I have Windows and Windows Office 2007, but as I said, is there anything that clearly stipulates on my hard-drive which operating system I am using.
I tried to restore my laptop to factory default today and i must have clicked the wrong option because it deleted my Hard Disk. now when i try to start it it says Operating system not found. Is there any way i can fix this? Oh and i have Windows 7 Starter edition, and its a Toshiba notebook laptop
This morning my computer, Sony Vaio, was working perfectly. I turned it off and after a couple of hours put it back on, to get to my surprise the following message " OPERATING SYSTEM NOT FOUND".Is it possible to recover my information still?
the boot manager was missing for my dell inspiron n4030 so i put the windows 7 repair disk in but when i start it it doesn't have any operating system listed
have got windows 7 ultimate version of operating system on my system, . but i also want to install windows xp in it for some reasons related to my education. can i install an other operating system along with the existing one, such that at every start up i could select the required os to be functioned
Basically I loaded up my Sony Vaio PCG-71811M laptop and it just has a black screen with 'operating system not found) I clicked F2 for the utility help to see what it said about the HDD. It doesn't say 'HDD not found, all it says is '0GB'. Really worried because all my university work is on there
I dropped my acer extensa 5235 from 1.5ft it landed flat. But now when i turn it on it says "operating system not found". Ive been searching everywhere for a solution but have not one. I do not have my windows 7 install disk as it was already pre-installed but i do have the windows 7 iso on a usb-stick. But when i go to install from the usb and choose custom install it starts to "Copy Window Files" but stays at 0% then an error comes up and says "Windows Setup could not reinitialize the deployment engine. To install Windows, restart the installation." ive tried to restart the installation but always comes up with same error?
I'm studying abroad in France and made a the great decision to try to restore my laptop to a system image on an external while in class. Anyway, my battery died half way through and on start my machine says missing operating system. I don't happen to have my restore disks here and would prefer to not have to go rebut windows 7.
My laptop is a HP Pavilion dv6500 (dv6647cl) just crashed randomly during basic internet browsing. I turned it back on and I get the Operating System Not Found error. In the BIOS I do not see the hard drive recognized. I connected the hard drive to a different computer and it is recognized and it appears as though nothing is wrong with the drive. Is it safe to say that internally the SATA controller is dead? Will edit after running diagnostics and sector tests on the drive.
My rather new Sony Vaio started having BSOD crashes, usually (but not always) after being asleep. After the BSOD, the restart would fail, with a message saying the operating system could not be found. But, after a couple restarts or a cold reboot, it would find it and start without problem. I reset the bios to defaults, did a system restore to before the crashes started- no luck. To make matters more complicated, the BSOD flash so quickly I don't get error codes, and no matter what I do (check pagefile size/location, system settings), my computer doesn't make a dump file. The event viewer only lists a critical error that the system rebooted without cleanly shutting down first. I called Sony, they had me run one of their hard drive check programs (not chkdsk and it passed), and then made me reformat/recover using the hidden partition and their recovery software. Besides the annoyance of the clean reformat and all my software settings etc not restoring quite right, three days after the reformat and I have another BSOD, and again, no .dmp file or any other clues (and of course, all the previous error reports got wiped).
I've had a problem with my ACER Laptop, and I need help fixing this Black Screen Of Death. I started up my laptop today, and BOOM! An error popped up and I have no absolute idea how to fix it. [code]
When did stability become an issue with operating systems? Was it around the time dial up modems were used as Windows monitor stands? Surely such a stack was not as stable as when people used to put monitors on top of thick telephone directories. Was it when combinations of operating systems and programs often failed for no apparent reproducible reason? What happened to all the operating system bugs? Surely the bugs did not disappear as operating system stability became a concern. I'm trying to pin point the year. I guess it would be the mid 1990s but I'd like to hear your opinions.
I have an Asus K60I, and when I start it up, a message appears telling me to choose an operating system, and gives me two choices...
1)Boot Client OS 2)Boot MRI PE
When I go to advanced system settings -> startup and recovery-> there is nothing listed under Default operating system, and the dropdown menu is empty.
My sony vaio is about 2 years old with a Windows 7 64 operating system. I changed the hard drive to a 500GB Toshiba. When I turned the computer back on it said "Operating system not found". I was told to turn off my computer and then restart while pressing F2. The new hard drive showed up on the screen. Then I restarted the computer again while pressing F10 but it says "Operating system not found".
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.
I have a Sony Vaio VPC-EC2TFX/WI, Have tried rebooting several times with no change.This computer was working fine last night and when I tried to turn it on this morning, I got the Operating System Not Found message
I have a Windows 7 Computer but I want to put Ubuntu Linux on a separate partition. I can't figure out how to do that. I already have the iso and have a new partition
