Operating System Was Not Found When Try To Wake Computer From Sleep Mode?
Jan 3, 2016
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 upgraded to Windows 10 and now I cannot wake up my computer from sleep mode. With Windows 7 and 8.1 all I had to do was tap any key and the computer would wake up. Now that doesn't work. I have to press and hold down the power button to force a shut down and then restart. This problem only appeared after I installed Windows 10. How can I fix it?

I have an HP pavilion g6 notebook laptop computer. I have recently upgraded from Windows 8.1 to Windows 10. I had occasion to put my computer to sleep! I had been working on my college courses for a few hours, when I needed to take a break. I put my system to sleep, but when I returned to complete my assignments my computer would not turn on! It went to an off black screen, and locked up! When at sleep the power indicater blinked, which indicates that it was in sleep mode.
When I tried to awaken my Pavillion it locked up, and the only way to regain control was to manually force it to shut down (i.e. hooded power button down.) thinking this may be due to system clutter I cleaned both user disc & system files using the Windows disk cleaning function, found through the control panel, looked for both HP updates, and Windows updates.
Later I again tried to awaken my machine after putting it to sleep, and had a repeat in the inability to awaken it! A third and the last time I tried to awaken my PC from sleep I noticed that for some reason, and somehow the indicator light was solid, the screen black, and I heard my computers fan running!

When I put my computer in sleep mode, it won't 'wake up'. I have to manually turn off the computer and then start it up again. This has happened twice. I'm not putting it into sleep mode until I find out what's wrong and that's exasperating as I normally leave my computer on all day so I can periodically play my games.

Rig only a few weeks old and I noticed for the second time now when my computer is left alone for awhile it acts like it's in sleep mode but mouse and keyboard don't seem to be waking it. I fixed it last time by just restarting computer...

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 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 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 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.

1. My PC no longer shuts down. It starts to shut down but then never turns off. I have to hold down the power button to turn it off. Really weird.
2. When my PC goes into sleep mode it will no longer wake up. I've pressed every button on the keyboard but nothing wakes it up. The only way to get it back on is to hold down the power button to switch it off, then switch it back on again.
3. Now that Edge has replaced Explorer, I'm having trouble with some websites and also there's an issue with Java. Windows 10 removed Explorer but when I've tried to download it I get the message:
Looking for Internet Explorer? You're in the right place, but Internet Explorer requires a Windows PC.
Well, I do have a Windows PC!

Came across my first major problem. When I try to go into sleep mode (either through the Start menu or pressing the power button), the hard drive light blinks for a second then the screen goes black. BUT... my power light stays on (should be blinking) and pressing it again, the mouse button... nor any key press on the keyboard will wake it up. I had to hard shutdown (holding the power key down for like 5 seconds) for the light go off and had to keep rebooting from scratch.
That's a major pain since waking up out of sleep mode is normally much faster and convenient. To make things worse.... it seems like 10 takes longer to boot up from scratch than 8.1 did. I've yet to see if SHUTDOWN works properly or not. Not a happy camper on the sleep mode issue. It worked under 8.1 just fine.
EDIT: Shutdown goes through a longer process, but ends the same as sleep does...... The power light stays on.
I'm using an HP Envy w/ i7-4510u CPU / 8GB RAM / 4GB Nvidia GTX 850M / 1TB drive
EDIT#2: Now SLEEP and SHUTDOWN appear to be working properly and Windows 10's boot up times are as fast or faster than 8.1 now. It's like a car and trying to clear out the lines of bad fuel before it runs right. Just some weird hiccups.

I put my pc on sleep mode about everyday, but when I try to wake it up, it completely shuts off. I usually have sleep mode on overnight. I've check and messed with some of the Power Option, but they all seem normal.

Laptop does not wake up from sleep when either power button, keyboard buttons or mouse touchpad are pressed. A forced reboot is always required. HDD light off, monitor stays black and battery light and fan still on.
Have had this problem for over a week since downloading and using Advanced SystemCare and Driver Booster. Once the problem occured I uninstalled them but nothing changed. Also there was a few recent windows updates at beginning of March but haven't read anywhere that they are causing similar problems. Have tried the obvious fixes but nothing seems to work.
SPECS
Asus X555LA
Windows 10 Home

I hear the computer turn back on and the light is on, but the screen is still black. My mouse and keyboard are unresponsive (can't turn backlight on). I have to do a hard shut down. When it's back on, it's like it woke up from sleep mode, not a fresh restart.
This just started happening today I think so I did a system restore, but the problem persists. The only thing I remember doing today was updating my ATI drivers.
