View 7 Replies View RelatedI'm in China and bought a new laptop, it's a Lenovo and it came with a Chinese operating system. To get an English operating system, I downloaded a copy of Windows 7 Professional. Once I installed Windows 7 Professional, I realized that the student key I got from my school was for Windows 7 Ultimate and wouldn't work with the Professional version.
Then I download a copy of Windows 7 Ultimate and burned it to a disk. When I went to install this, it wouldn't let me put it on any of my partitions (the laptop has 4) so I formatted the secondary one with like 860GB of space but then I thought that I would never need the Chinese operating system again so I formatted the Primary partition as well. However, after formatting them, it won't let me install my hard drive to any of the partitions and it tells me "Windows cannot be installed to this disk. The selected disk has an MBR partition table. One EFI systems, Windows can only be installed to GPT disks".
Now I can't start my computer because the operating systems are gone and I can't install my operating system. I have no idea what to do.
I installed the Ubuntu Operating system on my computer by mistake. Foolish. But that's what happened.I thought I was installing the Ubuntu that is used for storage purposes.When I tried to restart my computer it would not restart.I inserted the "Repair disc Windows 7 Ultimate 64-bit" and eventually I got my computer to startup.So I am still able to use my computer normally.But my computer now seems to be totally corrupted because all drives are labeled incorrectly and Data1 and Data2 are completely missing. I know this is true because I saw the above info while using the Repair disc Windows 7 Ultimate 64-bit.It seems that I am stuck with a corrupt computer.What are my options?Is my only option to reinstall windows 7?Or do a backup from an Acronis image file? What can I do?Moderator Edit: Moved topic from Virus, Trojan, Spyware, and Malware Removal Logs to the more appropriate forumRoger
View 6 Replies View RelatedI've had this Sony Vaio VPCEE3WFX/BJ for about a year now. It was working fine until a couple of days ago. My little sister was on it and was playing Poptropica and that was the only thing she did on there. After shutting down the computer, I didn't turn it on until the next day. After pressing the power button, I got the Vaio screen or whatever the screen is called. After that screen has loaded, Operating System Not Found appears out of nowhere. I turned the computer on and off a couple of times but I still received the "Operating System Not Found" After I tried turning it off and on, I tried turning it on again but pressing F8 so that I could get some start up options. I was able to get to the screen and select "Start Windows Normally" From that point, I can get to the login screen and my desktop. The only problem with that is that it takes around 20 minutes to get to the login screen. Once I enter my password, it takes around 10 minutes to get past the login screen. Once past the screen, I get a black screen with the cursor in the middle. If I wait around an hour or so, the desktop will finally load and I will be able to do what I please with one condition. If try and open a program or anything it takes around 10 minutes to load it up and if I try to load a page on Google Chrome, it takes around 5 minutes just for one page.I was thinking about calling Sony to see if there was any way I could send in the laptop for repair before the warranty expires which is in just a couple of weeks.
I have tried Startup Repair but it was no help because I get errors when I try and click some of the solutions. ( I can't remember what the errors say) Also, would re-installing Windows 7 solve the problem? The laptop did not come with a recovery disk or Windows 7 installation disk.Edit: I forgot to mention that I ran 2 virus scans (one from AVG and one from Malwarebytes) and the results came out clean except a file that AVG reported was unsafe due to little known users using it. I ignored it but still deleted it because it was a program one of my teachers told me to download from the home website. (the program was Autodesk Inventor 2011)
my computer started laggin really bad, couldnt even move mouse without major lag. Anyways so i got sick of it and reinstalled windows 7 64 bit, now my computer gets stuck at loading operating system. Thought it was SSD so took it out and put in a 500gp wd hard drive (I know it works fine, becuase had it run on company server all week before i used it) so then i installed it on their and still was stuck so then i took out my other 500gb wd hard drive where i store all my files, just so i could make sure that my OS can only install on one item and not be corrupted by any other drives. So now the problem still presit and i have tried resetting my bios by taking out battery for 10 min, still no results, so then i ran startup repair (Had no hope) and it still didnt work. Need help and bellow I will post all my hardware, by the way my computer is a custom build and has been working fine for 2-3 months. Also I do overclock, but i doubt that had anything to do with it, because it started to lag weeks after i started overclocking. [code]

View 3 Replies View RelatedI have a HP laptop that had Windows 7 installed on it, one day i got a message saying there were updates available, which included Service pack 1. So, i went ahead with the install however, when my system rebooted after the install there was an error message (i cant remember what it said, it was a while ago) so i immediately tried to put my windows 7 disk in, which would not boot. I have gone into bios and changed it so that it was the first boot item but still didn't work, even with F8, F12 etc. So i decided to borrow a recovery disk from a friend, it is a general one of the internet, i went through the repair options which didn't work, so i decided to format the hard drive which was successful. So now when you boot, as you would expect, you get a no operating system message. I try to put my Windows 7 disk back in to install it fresh but it still wont work, its like theres nothing in the cd drive.
View 2 Replies View RelatedI just bought a refurbished Dell desktop PC that came with Windows XP Home preloaded. I have bought the disc from Microsoft for Windows 7 OS and want to do a clean install on that PC.
When I put in the Windows 7 disc and restart the PC, the cursor will appear for about a minute flashing in the upper left hand corner of the black screen before the machine finally boots to Windows XP Home edition.
Things I�ve tried:
1.Reboot and hit F2 to check the reboot order which is already set to do �Onboard or USB CD-ROM Drive� as the first choice.
2.Reboot and hit F12 to see if there are any other options that make sense (which don�t to me).
3.Reboot in Safe Mode (and then what do I do?)
Here�s my PC�s configuration:
Dell GX280 Desktop
Pentium 4 2.80 GHz
750 Gb Hard Drive
2 Gb RAM

View 4 Replies View RelatedI built my computer a few months back, and it worked just fine. About three months ago, I got two 3TB and put them in RAID 0 along with my four SSDs (which were also in RAID 0). When I hooked up my hard drives, Windows stopped booting. It installs, but when it restarts to finish the installation it says "missing operating system." I tried reinstalling it in every way imaginable: With only one of the hard drives, no RAID, just one SSD, using the hard drive, using a USB dvd drive, etc.
the parts:
Cougar GX 1050W
Z77A-GD65
i7 3770K
GTX 680
32 GB RAM
4x 120GB SSDs in RAID 0
2x 3TB hard drives in RAID 0

I have recently purchased a Sony VAIO with Windows 7 pre-installed. Completely randomly (this happens more often now - every 30 mins or so) the computer will freeze up, then brings me to a blue screen telling me that "A problem has been detected and your computer has been shut down to prevent damage". This stays on for only a second then the screen goes black. Five seconds later I get "Operating System Not Found". The only way I can use the computer again is to hold the power button down (which gives the computer a full power off), then turn it back on again.
View 9 Replies View RelatedI recently bought a DIY computer package from Tigerdirect. I put all the parts together, making sure to handle the parts correctly. Once everything was hooked-up, hardware-wise, I tried to install Windows 7 off of a friend's USB drive. It almost worked, but it requested that I insert a disk into the drive, which I couldn't do.I bought a brand new Windows 7 OEM version. Computer still won't boot-up, even though BIOS screen shows that the optical drive is connected. After checking the boot order sequence several times, I figured that the driver must have something wrong with it, so I bought a cheap DVDROM. Both optical drives are made by LG (not sure if relevant) but neither work. In fact, neither one would even spin-up the disk. Message on screen reads: 'Reboot and Select proper boot device, or insert boot media into boot device and press any key.'

View 7 Replies View RelatedSuddenly 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.
