Lenovo ThinkPad T520 / No Operating System Found
Sep 21, 2015
so a while back when the Windows 10 Upgrade had popped up on my computer, I upgraded with no problem at all. I wanted to do a factory restore in order to clean up my laptop completely, however while updating, the power went out and the computer shut off. Logging back on, I couldn't access Windows at all. I couldn't even get to the login screen. The message that had popped up had said that no operating system was found and to press Ctrl+Alt+Del to restart. I have a Lenovo ThinkPad T520.

I have a k430 Lenovo desktop. When I got home last night, I was greeted to a blank white screen that was unresponsive. When I restarted my computer (holding down power button) it gave me this error. I've tried swapping my SATA cable with an older computers cable, and a couple other fixes with the BIOS recommended from the Lenovo site, and I even tried running my windows 8 install disc to no avail. I can feel the hard drive working by touch. I tried booting in 'legacy' and it said no hard disk was detected.

Whenever booting my pc I get a "operating system wasn't found error". I've checked to make sure my hard drive was set to the boot drive and I've tried reinstalling but that doesn't work either.

My Acer Aspire One was upgraded to Windows 10. Eventually, I ran into some issues with the start menu not popping up, so I decided to run a clean reset of Windows 10. The reset failed, so I turned off the notebook. When I turned it back on, the message "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. Press Ctrl+Alt+Del to restart," popped up. My first option was to try to use either f2 or f12 to see if there was some way to get around the issue, but then I remembered that, recently, my notebook had stopped responding to those commands. I do have a USB Logitech K120 keyboard hooked up to it (since the original keyboard messed up,) but it had been working fine for those commands and such up until now.
Today, I downloaded Win 10 using the Media Creation Tool in an attempt to create a bootable USB drive. I plugged that in, yet it doesn't seem to recognize it at all. The same message pops up as before. My acer doesn't have a CD-ROM or anything of the sort, so the USB appears to be my only hope. Is there anything that I can do? I'm hoping there's a way I can force the notebook to recognize the USB, or at least boot into the f2 or f12 commands to see if I can use them in any way.

I upgraded from windows 7 to 10 about 2 weeks ago, absolutely no issues, i was happy with everything.
My computer had froze and i forced a shut down via power button. Upon starting again i was greeted with "no operating system found"
I fixed that problem now im greeted with a black screen with something like "no bootable device found please detach any devices"
What i have tried is....
Made a win10 usb with the media creation tool from another computer.
Startup repair does not work, error is "the hard drive is locked"
I have tried with the command prompt the following commands
Bootrec /fixboot
Bootrec /fixmbr
Bootrev /rebuildbcd
*rebuildbcd tells me i have 2 installed windows os. One is regular windows and windows.old*
(If i say Yes to rebuild both of those, my media creation usb stops working if i restart. I get the error 0xc00000f and have to recreate the media creation tool on the usb. Otherwise i keep getting the same error)
I have also tried different sata ports on my motherboard, resetting bios settings, changing boot order, changed sata cable. What else can i do?

I did the conversion from Windows 7 to Windows 10 about 1.5 months ago. This is a Dell Vostro w/Intel Corei5 desktop
All was fine until I attempted to wake the computer from sleep mode recently and got the following error.
An operating system was not found. Try disconnecting any drives that don't contain an operating system
Press Ctrl+Atl+Del to restart
I disconnected the two external drives I had connected and tried again with the same result.
On startup, I've hit F12 to run through the Dell ePSA Pre-boot system assessment and it passes all the tests System, Cables, OS boot Path, Hard drive, cd rom drive, video card, cpu fan, system fan processor and memory.
I have the original 7, 64 bit installation disks, but nothing for Windows 10. What's the best way to get this thing going again?

I have recently upgrade to Win 10 from windows 7 and it was running fine until it started booting with the analyzing and repairing windows screen. I had tried to get out of it by windows repair and by system restore but there were no points to restore too. I ended up trying the windows reset which failed when I selected to leave my files so then I tried the reset including removing my files. It failed part way through saying it could not complete the action and now when I boot up every time I get "An operating system wasn't found" etc. I do not have a windows CD or know my windows registration number.

I upgraded my Lenovo Thinkpad Tablet 2 to Win 10 a few weeks ago. Since then, it won't fully power down 9 times out of 10. I close all apps, and select shut down from the power menu, and it appears to go through the shut down process, but it stays powered - the haptic feedback Windows button buzzes when pressed. If I don't plug in the charger it will kill the battery.
The only way to power it back on is to hold down the power button for 15 seconds.

Recently after getting a fresh install of windows 10 on my ThinkPad T450s, I occasionally get BSOD while in the middle of doing various tasks (word processing, web browsing, onenote, etc.). Because of the fresh install, I downloaded many applications so I don't know what's causing the issue. The error code is 0xdead039e, but I couldn't find any information about it online.

I have a new Lenovo ThinkPad Yoga 14 with the NVIDIA 940M discrete graphics option, and after a clean install of Windows 10, maximising pretty much any application results in a blank (and faintly flickering) screen.
I got my unit about a week before Windows 10 was released, and intentionally didn't use it much for that first week. Then, shortly after release, I downloaded Win10 as an ISO using Microsoft's own tools, wrote this to a DVD, then booted the laptop using an external USB drive, carrying out a completely clean install (and blowing away the 8.1 restore partition, which in hindsight might have been a mistake). I allowed Win10 to install all drivers, then went to the Lenovo site for anything missing. End result is that pretty much any application (excluding the Edge browser) blanks the screen when maximised.
After that, I went back to 8.1 - again with a clean install due to no longer having a restore partition, and documented the steps taken this time:
Installed 8.1 from downloaded ISO written to DVD, via USB DVD drive
Ensured unit was offline
Installed latest Intel HD Graphics 5500 drivers 6.16.00.3174
Tested maximising applications, no issues
For each of the last three releases of the NVIDIA drivers (in case there was a problem with a particular release), being 352.30, 353.30, and 353.62:
> Installed the driver
[Code] ....
End result is a fully working 8.1 install - no problem with maximising applications.
I then disconnected from the network and did an in-place upgrade to Windows 10, again documenting the steps taken:
Immediately after installation, there were no Intel drivers and no NVIDIA drivers installed
Display was using Microsoft Basic Display Adapter only
Maximising an app instantly blanked the screen - interesting given the lack of vendor-specific display drivers installed at this point...
Connected laptop to network again and allowed Win10 to install all updates (including drivers)
On restarting, drivers were automatically present for Intel HD Graphics 5500 and NVIDIA 940M
Testing maximising an application again blanked the screen
As a test, the 940M was disabled via device manager and all GeForce drivers uninstalled
Testing maximising an application again blanked the screen
I've tried a further Windows 10 clean install since the above, but with the same result - doesn't seem to matter regarding the installation order of drivers, etc, or if I manually download these vs letting Win10 or Lenovo's system update application install them...
Plugging in an external display via HDMI shows no such issues, e.g. maximising applications is fine. If the display is mirrored, the internal screen still flickers with maximised applications.
On talking to Lenovo support yesterday, the response was that this "is a Windows 10 problem" and that I "should contact Microsoft" for a resolution...
I know I can go back to a clean Win8.1 install, but would much rather be on Win10.

A while ago I bought my pc off ebay. It came with windows 8 already installed. The guy who sold it said that he built the pc and decided not to use it so he was selling it. I've upgraded to windows 8.1 and now to windows 10. How can I to check if my OS is OEM?

Am I alone, or are there others out there who would like a DESKTOP operating system to use with their DESKTOP computers? Swiping, pinching, tapping, chanting arcane spells to your Cortana crystal ball, ... -- all these may be OK on a phone or tablet, but don't they just add to the effort of using a desktop computer?

So I upgraded to Windows 10 last week, & after a few days decided I wanted to do the reset feature to have a nice clean install. I was also getting an annoying pop-up error that looked like some sort of malware, but virus & malware scans weren't getting rid of it.
Ok, so I do the reset, & opted for full clean not the quick one, just to make sure I got everything off there. It took quite a long time ( about 15-20 minutes per 1% progress), so I left it & came back later. When I got back I had an error message that said "There was a problem resetting your PC." with my only option being to click cancel. So I did. after that it brought me back to a reset screen, where I attempted to do the quick reset a few times, & it failed after a few percent each time.
At this point I decided to shut down & try again. When I booted back up I was greeted with the lovely message of "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. Press Crtl+Alt+Del to restart"...so my pc was wiped but the reinstall part failed somehow it seems, leaving me with nothing.
I created a bootable usb for Win10 from the Microsoft website, following their instructions to the letter. Installation seems to go fine ( Copying Windows files, Getting files ready for Installation etc). That screen finishes up & I get a Restarting in 10 Seconds screen. I let it restart & then I get stuck at a black screen with a blinking cursor in the top left corner.
I have done some reading on this & tried everything I found, nothing has worked. I've let it sit, tried hitting Crtl to type password then hit Enter, I've unplugged my second monitor & any non essential USB devices, everything. I've tried installing multiple times, to the same result.
Also worth noting that I was unable to revert back to Win7. When I put my 7disc in I get a message saying "A required CD/DVD drive device driver is missing. If you have a driver floppy disk CD,DVD or USB flash drive, please insert it now."
I've used this disc many times with no issue, & now I can't even reinstall 7?

My dell 7500 has windows 7(C: drive) and windows 10(F: drive) installed on the single internal HDD. It also has three USB disks used only for data. When I boot I get a message saying that an operating system cannot be found and I should try unplugging my USB drives and then reboot. When I unplug the USB drives and re boot, it finds the windows systems and finishes the boot process with no trouble.
Checking the BIOS shows only the CD-Rom drive and the three USB drives are listed in the boot order and the drive listing. I then deactivated the "boot from USB drives" item in my BIOS and then the computer boots fine.
Also, I have been experimenting with Ubuntu on a USB pen drive but have removed it. I suspect that there are some parts of grub hanging around.

I am looking forward to replace my laptop HDD with a SSD. My laptop is the Toshiba Satellite l70 pro 17.3". I have a basic idea of doing transferring windows 8 to an SSD but apparently it is harder to transfer Windows 10 to a SSD when compared to Windows 8 and 7.

Not sure what to do. I did find a page to uninstall Win 10, but I'm not sure it would do it correctly without the internet. I'm not even sure if it would work because I was afraid to try it. It is a HP computer and it was running on 8.1. I'm using my spouse's computer to post this.

I used the Windows 10 rest pc feature and selected the options to delete everything off of my drives. There was a problem during the installation and I clicked the option to boot back into windows 10. The laptop just boots into the MSI splash screen over and over again.
