Installation :: No Operating System Found And No Bootable Device
Jan 2, 2016
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 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.

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.

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 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 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.

I got myself a new 120GB SSD for the jump to Windows 10. I install the OS without problems from a DVD disk, boot up and begin to install stuff as steam, spotify and GeForce experience.
I remove the installation disk from my DVD reader and reboot. After the BIOS screen I get a message that claims there are no bootable media.
With the installation disk in the DVD reader everything works fine, I get an option to boot the installation even though the DVD is nr 2 in boot order after my sole storage unit.
I have tried to use all those bootrec commands to restore, repair or create a new bootmgr and so on. No installations of Windows can be found either. Been doing this for 6 hours now. I have reinstalled windows 10, 8 and 7. All with the same problem.
I plugged in one of my older 60GB SSDs and successfully installed Windows 10 on it. No sign of any boot problems. Booted without the installation disc. Same SATA connection on the motherboard. No changes in boot order.
So my thoughts about this right now, is it possible my new SSD have a defect from the beginning? Something in the hardware/hardware controller?
And yes I have searched around and Everyone seems to get it working with bootrec commands. I don't...

My computer was on sleep mode and my sister plugged it off. I restarted my computer to see that an error message said " you pc needs ti be repaired " and something abour rhe boot configuration data being missing. So i researched and found a tutorial on how to fix the bcd. i typed "bootrec rebuildbcd" on cmd from the windows recovery media advanced options and came up with
"Scanning all disks for Windows installations. Please wait, since this may take a while... Successfully scanned Windows installations. Total identified Windows installations: 1 [1] D:Windows Add installation to boot list? Yes<Y>/No<N>/All<A>:"
I typed in "yes" however it said "the requested system device cannot be found."

I am using a Lenovo Y510P, originally installed with Windows 8.1. I upgraded to Windows 10 in July and it worked fine-ish up until now. I have recently (for the past few days) encountered quite frequent BSODs, most of the time with the code CRITICAL_PROCESS_DIED. I tried clean-resetting Windows 10 but the error kept recurring. It happened really randomly, sometimes when I was browsing the web in Chrome, sometimes when I was typing something in Skype, or in Microsoft Word, or sometimes when I just tried to refresh the desktop. So there's really no predicting when it is going to happen
P/s: After rebooting from BSOD, for some reason the system does not recognise any bootable device (and so it tries and fails to boot from my network?). But when I hard-reset the computer by holding the power button the system can boot into Windows again. I used to have grub2 bootloader for my Ubuntu, but after the first of such BSODs it died, somehow, so the system just booted straight into Windows from then on.

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.

one part before installing Windows 10. In creating a virtualbox you will see three lines with the top to fill in with name " Windows 10 Technical Preview " then second line with type --Microsoft Windows and the last one with version -- I wasn't sure which to pick the right operating system of my laptop. Well I do know that my operating system is Windows 7 Home Premium SP-1 64X but see several youtube videos show with Windows 8.1. Am I click with Windows 7.1 in the line. Is that correct.

Recently, I purchased a Microsoft Surface 3. From the day I got the tablet, it has been having freezing problems that seem to progressively get worse and worse. Today, I couldn't go two minutes on my Surface without having to restart it.
I would prefer to return the product, but since I can't, I decided to first try to update it. The update kept getting frozen, encountered an error or would just be stuck at 0%.
After exhausting all the other options I knew off, I quickly moved what little files that I had off of my tablet and then performed a factory reset.
The factory reset got stuck at 99%. And I don't mean that it just was there for a few hours--no, the screen literally froze. So I restarted the tablet again, which brought me to a screen that says, "Choose an Operating System" that has two options. Both options are "Windows 10 on volume 3." There seems to be no distinction between them. But the problem is that if I click one, and it doesn't matter which one, or if I just let the tablet automatically run on one of them, it loads for a few seconds with the "Surface" screen, and then immediately loops back to the same "Choose an Operating System."

Anyhow I am currently using windows 7 (not a fan of windows 8). Since windows 10 is released I wanted to install and try it. Initially I installed windows 8.1 in my D: drive (works normally as far as I can tell), and upgrade it to windows 10. I am keeping my windows 7 in drive C: as I do not have any other working computer if the installation failed.
So halfway upgrading from windows 8.1 to windows 10, the upgrade failed and a restart is needed. When restarting I tried to reset the installation but even that is failed. When restarted again there is no operating system in that drive (drive D: ) ??
Currently I tried to reformat my drive D: (windows 10) with my current windows 7 (installed in drive C) but it says the volume is in use by another process but it refused.
Summary
Drive C: - windows 7, still functioning properly
Drive D - where windows 8.1 is located and upgraded to windows 10 but failed, currently cannot detect any os when I boot from drive D: , and cant format the drive.
I know its really complicated the way i installed my windows 8.1 with my windows 7 intact, but I'm worried if the installation failed, I have no backup computer to fall back.

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?
