Operating System Stability
Sep 8, 2010
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.

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.

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've loaded Windows 7 RTM on my Dell M1330, as it's not a business-critical PC for me and I figured it would be good to test on. It was running XP Pro previously and worked great. With Win 7 seems to run ok for a little while and then starts randomly freezing and the system becomes generally unresponsive...then comes to for a little bit and then freezes up again. It's almost as though I have better luck trying to get something done by holding down the power button and then booting up again to get a few minutes of usable time. Seems to be aggravated faster by using an internet browser (IE or Firefox).
I've tried both x64 and x86 as clean installs and had about the same luck. I've applied the most recent Vista drivers supplied by Dell and the most recent nVidia drivers. Basically, I've tried every kind of driver combination I can think of, but it still acts like a system that has driver issues, but I haven't been able to pinpoint which device is causing this. Same install disk, etc yields good performance in a VM. So, my question is...has anyone with an M1330 w/NVidia video card been able to get Win 7 RTM running solid? If so, what did you do to yield the best performance?

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.

The other thread was really poorly titled, and im getting an issue: Could not find file 'C:msinfo32.nfo'.I have a pc with a 3770k intel cpu and a msi-g45 mobo long story short im getting BSOD's.what seems to happen is ill turn the pc on and it will gradually slow down untill it bsods, it doesnt seem to be affected so much by what i do it seems to inevitably crash though.Ive noticed through CPU-Z where my CPU will jump between around 800-1600mhz to 3700 which of course is a feature with the new chips but after some time itll stop jumping and sit at 1600 and then 800 then my core freq will drop between 100 and 50 and kind of swap around there before crashing.I thought maybe my psu wasnt giving enough power to the chip but i tested that and it seems to be working fine.

I have three machines in my house running Seven. However I will focus on two.
1.) MSI Mobo, AMD 4200+, 2GB RAM, etc. (Look in my stats for the desktop)
2.) HP 6735s, AMD Turion X2, 2.5GB RAM, 256MB Dedicated Radeon HD 3200.
The MSI ran Windows Vista Ultimate 32 bit. I had everything I wanted on there so I didn't want to do a clean install. Once the Seven upgrade finished, it was fantastic. The only program that I already had that didn't work was Daemon Tools. However AIM still worked, and you can't install AIM from Windows Seven.
Now on my laptop, it came with Vista, but I wanted Seven. So I did a clean install, because I didn't want all that HP garbage that comes with them. Now I have an issue with sleep. When my PC goes to sleep, and I wake it back up, it runs ok, but then when I go through certain tasks it hangs.
Sometimes if I awake it with my wireless off, it won't come back on, it won't recognize plugged in add ons, and when I go file searching it hangs, like if indexing is messed up. I am considering, rolling back, getting Vista all the way to SP1, downloading AIM, and whatever else I need, and just upgrading it like I did my PC.
Also, the third PC which is a Dell does not perform as well as it should, but does fine in Vista.
I am not a Windows expert, but from deduction, I can conclude that Windows Seven stability is greatly enhanced when it is upgraded from Windows Vista.

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?

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 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.

My boss' laptop needed fixing. Its a Sony Vaio (VPCEE21FX). I boot it on and after post I get the 'Operating System not found' message. So I grab my handy dandy windows 7 disk. Boot it from that and get the installation going. It was on the "Expanding Files" part. Now at the same time I was restoring an old xp machine so my eyes weren't glued to the laptop's screen. I looked over and the laptop was off! I checked the power cord it was plugged and everything. I booted it back up and I get 'BOOTMgR is missing press ctrl alt dlt to restart'. I can't access bios or boot menu. I've been restarting it while press f1 f8 f12 and Del, as those are the known keys, but nothing. What do I do?

I've just recently installed one of my favorite old games, Starcaft. after playing it for about a week I've found out that there is a 100 milisecond delay on any action you make when using Windows 7. I desided to hook up my old hard drive and It's telling me that it's corrupt, has a virus, I believe because the mother board doesn't recognize it I think. Is there any way that I'd be able to get that hard drive working or maybe ever use it as a second drive, some how?
