Windows 10: Missing operating system
Nothing yet, maybe I'll have to make a new clean install of win8 in laptop. :/.
This is lesson to ALWAYS clone my os partition when attempting upgrades. I did that now with the functional non activated win10, but I don't want to stay with a no activated system
I'm willing to try again in the weekend phisically removing the hdd from laptop leaving just the ssd, instead of disabling the sata port of hdd in bios. But I doubt if it will make any difference
Apparently I was lucky or whatever, but I did get it working. Look at my previous posts to see what worked for me. YMMV...
I cannot send a PM to you due to new account so I will ask it here
I have one and planning to upgrade it to Windows 10.
However I contacted Clevo support and they say there is no Windows 10 drivers for W350ET.
Are you on Windows 10, if so how do the drivers run? Are function keys and fingerprint sensors working?
The fingerprint sensor i never used/installed. Everything else seems fine with previous windo8 drivers.
I did it! It was not smooth, but I did it!
I tried again and got the same error, this time instead of just format partition I excluded and tried to create new one. Windows gave error, saiyng that could not create a GPT partition because it had a MBR. Só I disabled uefi and everthing, installed and got the same error.
So this what i did after:
1. Physically removed hdd leaving just ssd.
2. Cloned/Backed up my second "game partition" of ssd
3. Installed Win8 clean install telling it to EXCLUDE ALL partitions of ssd (UEFI enabled so win8 use GPT).
4. Win 8 recreated paritions using GPT.
5. Activated win 8
6. Updated from media tool and IT WORKED!
7. Repartition SSD and restore my games partition (doing this now)
8. Reinsert HDD in Notebook
OK, I did it too!! Most people have the problem with a laptop with a SSD disk. So had I. I borrowed a 2.5 inch harddisk from another computer. I made an image from my SSD disk and transferred it to the harddisk. I started the laptop from the harddisk and started the windows 10 upgrade from a dvd. And to my surprise the upgrade went well this time!! Windows 10 was activated. After that I made an image from the harddisk with windows 10 on it, and transferred the image to my SSD disk. I placed the SSD disk back in the laptop; windows 10 started and was activated!!! Very strange that replacing a SSD disk with a Harddisk solves the problem. I have no explanation, but I am on Windows 10 now. Next step will be to try a clean install, after making an image so that i can go back in case of failure.

Did you ever get to windows 10? I had the exact experience. I upgraded and it was working fine. I did an update and ... boom. "Missing operating system" I'm currently rolled back to windows 7. I tried with a new ssd, hdd, fixing the boot records. no luck
Did you try changing boot mode in BIOS? Like what I did in this post: Missing operating system - Page 3 - Windows 10 Forums
Windows 10 Boot problems solved
Just suffered from the same problem and after some fiddling resolved it - hopefully this will work for you.
Been running windows 10 from an SSD for a while - in a multi-drive system. An old HD started to give errors so I removed it and replaced and then the problems started.
Windows failed to boot (cannot find necessary device)
Steps to resolve.
Created a repair disk on a second pc and booted into repair console.
Advanced - repair startup. (Didn't work but worth a try)
Advanced - cmd prompt.
Used diskpart to set ssd as active
You might need different disk / partition. (Still no joy at this point)
set disk 1
set partition 1
Back to cmd prompt in repair
Again still no go.
Tried to used the reinstall option - but didn't work 'disk locked'....
I also attempted to use BCDEDIT to repair the BCD file - but still no good
Finally got the show on the road again - with a little tidying to remove references to the old drive - all was still in place....
BCDBOOT c:\Windows /s c:
A simple solution that worked for me
I read through a lot of the messages in this thread. I was getting pretty worried that I was going to have to do a clean reinstall of Windows 8.1, and then the upgrade to Windows 10 and start restoring from backup (yuck).
But then I had an idea. For the upgrade I had created an ISO image of the Windows 10 upgrade, and then mounted it and copied all the files files to the root directory of a USB drive. That was what I ran to execute the upgrade.
When I got the missing OS message. I first tried turning off and turning on the computer a couple times. That did not help. Then it occurred to me that perhaps the computer is trying to boot from my USB drive which was still plugged in (and was not formatted as Bootable). So I took it out, cycled power again and this time everything proceeded as expected.
I hope this helps someone else who, like me procrastinated until the last day for the free upgrade.
