Sony Vaio Can't Find Operating System (Windows 7 X64)
Jun 10, 2011I have a 8-month-old Sony Vaio, running Windows 7 x64. The last couple weeks, it does this thing, where the screen goes totally black, and it says, "Can't Find Operating System". The only way to get out of this black screen/error message, is to turn the laptop off. When I turn it back on, it seems fine (except, it does seem to be running slower), but, the next day, there is the black screen/error message again.
I don't know a lot about computers, so these are the only things I could think of trying: running disk check, running sfc/ runnow, checking for viruses, and doing a quick diagnostic check on the HD (using Vaio Care). Nothing. I took it to a tech, who said I clearly took good care of my laptop, inside and out, and he could not figure out what was wrong with it. His only idea was to wipe it back to out-of-box, using F10.
Cannot Find Operating System
Feb 21, 2013My 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).

Jun 21, 2012I recently bought a 240gb ocz vertex 3 ssd to install my os on. I installed windows on the ssd and a bunch of bigger games on my other 1tb hdd and 500gb hdd. a few days later I decided to put my 2hdd's into a raid0 array. I didn't format them before doing this but I went into my uefi bios and changed it from ahci to raid then rebooted. I tried to create a 1390gb raid size then a 1300gb size but it said not enough room. so I tried to get back into windows and format them thinking that's what the problem was but when I selected to boot off of the ssd it said some crap about Nero booter or something and it wouldn't work. I tried changing the bios setting back to ahci but still wont work, I tried unplugging all drives except the ssd but it just says reboot and select proper boot device, the ssd is the first boot priority and its set to ahci so what the f is the problem

Oct 19, 2011Suddenly 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.

May 29, 2011I'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?

Sep 15, 2011I'm been working on this problem for over a day now and now I'm stumped.I've read dozens of threads and blogs all over the internet concerning this "operating system not found" problem but none of their problems seem to be the problem that I have.My computer just got extremely laggy and froze into a BSOD (blue screen of death) before turning off and showing me the "operating system not found" message during every boot.Usually when this problem showed up, it turned out to be a hard drive failure, but when I checked my bios, it listed my hard drive as 320gb. (So I'm guessing this has nothing or little to do with my hard drive.)
Here are the things I have tried: Safe modesThe "Launch Startup Repair" (ends up with at start up background and doesn't progress any further)The "Windows Memory Diagnostic""Last Known Good configuration"I've transfered the windows 7 .iso to a bootable usb and started up the laptop it got to the Install Now window and when I press that, the window closes and it shows "setup starting" and just stays like that.The only part that seems to be working like it's supposed to is the quick start/splashtop browser option that doesn't startup anything. (It only opens a browser for internet use and no other programs).I'm guessing the next step should be to open up my laptop and see if any of the cables are loose.ut after that I don't know what else I could do.
Edit- I have just checked and now the operating system not found message doesn't show up. when I start up with regular settings, it just gets to a blue screen and restarts.

Aug 29, 2010I am getting the "Missing Operating System" message on boot. Here is the strange thing...if I change the boot order in the BIOS and have CDROM first and choose not to boot off of it Windows 7 loads fine. If I put HARDDISK first then I get the missing operating system message. I have tried running CHKDSK, BOOTREC and the plain old Windows repair util. None of them have worked.

Dec 8, 2010My computer fell a couple days ago, and I had to get a new hard drive. nfortunately, my mother let my uncle who is NOT a professional install a "new" hard drive, which was actually his old one and came with Linux and not Windows. It worked fine but I wanted Windows, so he did something and installed Windows 7 from a flash drive. And it was great. Until this afternoon, when I accidentally changed the BIOS order and now I'm getting an "operating system not found" message... Is there something wrong with the hard drive (again, it isn't new) or did I just completely mess something up?

May 10, 2012I just bought a new laptop. It has one hard drive (C/)with 600gb and I partitioned it. However Im not sure if i did this correctly. I had to provide a file path etc and the only place to save the partition (E/)was on the primary C drive itself. (So now theres a file on the C drive called "E" with its own amount of memory).
I made the new partion into a primary drive and it shows up as such on "my computer". The current OS is windows 7 home premium but now I want to install windows 7 ultimate. I realise that Ive done things kinda back to front - my question is: if i install the new windows 7 ultimate OS, will the partition remain as it is or will it be ereased because its located on the C drive?

View 7 Replies View RelatedInstalling Games On Windows 7 Operating System
Jul 10, 2011I don't play many games on my computer, but occassionally I enjoy (or used to) playing Bejeweled or specifically Jewel Quest. I purchased the latest Jewel Quest game from Best Buy and it said it was compatible with Windows 7, and in fact in installed fine. When I attempted to play the game I got a gray screen, then a white screen then a screen that resembled a flat with red, white and green strips and these three screens just kept alternating.
I couldn't stop them; I couldn't Cnt/Alt/Del out of it and I coluldn't get to the start menu to shut down. I turned the computer off manually. Upon restarting, the computer would not go past the "Windows" screen. I did this a number of times, but was never able to get it to reboot normally. I ended up having to boot in Safe Mode, uninstall the game that I had installed and do a recovery reboot to an earlier date (yesterday) in order for my computer to come back up normally.
I had this very same problem when I tried resetting the screen resolution manually to play another game that I had installed. I ended up abandoning the idea. I am guessing that the problem that I am having has to do with the 64bit Operating System as opposed to a 32bit - but if the game says it is compatible with Windows 7 would it not automatically be able to run on a 64 bit Operating System.??? I am not so much concerned with the game as I am with other software that I may want to install in my computer. if there is a patch or a Windows update that I need to install to fix this problem?
