After I upgraded Windows Technical Preview, which is running in dual-boot alongside Windows 8.1, my computer turned off. When I turn it back on, the BIOS asks which hard drive to use but there aren't any listed apart from the CD-Drive...

What can I do? Does anyone else have the same problem?

Thanks for any help!

Sounds like a serious issue. Did you try to reach the disk from another OS already? (run ubuntu on a USB or something).

Try a live CD to check if the hard drive is still ok.

[Timoshu]

Yes I have tried to run it with Ubuntu on a CD and it says "Filesystem not found">
I have also tried Seagate Seatools for DOS to test HardDrive and it says that no hard drives have been found...

Either your Hard Drive is dead or the Sata Cable has gone bad. Try replacing the Sata cable and see if it shows back up. Also try a different Sata port on the Motherboard and see if that works. If it doesn't show back up in the Bios sounds like your HDD died.

I'm using a laptop and the SATA cable doesn't seem to be able to come out. Is it possible to take it out on a laptop? Furthemore, there isn't any other Sata ports.

Insert any Windows CD you have and start new installation of system.

[Conan143]

did you try with usb having windows 10 or 8.1 setup so that u can make sure whether hard disk is working or not.

[BatteryLife]

Same happened with mine after update.

I'm sure the hard drive is not working. However, it does not even try to spin or make noise. The problem is probably the SATA cable not providing power to the hard drive.

Any luck fixing it? Are you sure it was the Windows Techical Preview (Windows 10) update that caused your hard drive to stop working?

Erm, of course, I can't be sure. I downloaded the update, and pressed Reboot when prompted to do so.

It rebooted, had a progress screen. Until arnd 70% I think, then it rebooted, and stated "reverting to previous windows version" or smth similar.

Then it rebooted again. As usual,the manufacturer, in my case, Asus' logo appeared. But then it shows the msg "3rd master hard disk error".

So... Yeah :P

This is very unlikely. I would try what BataBole suggested. I would go one step further and suggest trying a reinstall of any Windows version other than the 10 preview at this point.

Or try disassembling an external one and put it in. They're all 2.5" anyway.

When HDD is not working properly or any internal part of computer, PC starts to beep beep. Your system installation has failed, so please start a new one!

Beeps are very inconsistent across different makes and models. My brother's laptop got a dead HDD and there was no beep whatsoever.

The Windows preview doesn't have a glitch that eats your hard drive or anything like that. Installing a new operating system is taxing on your hard drive, so if your drive already weak, the install could have put it over the edge.

[KM Johnson]

Same thing here. My relatively new y510p Hybrid SSD/HDD is now dead, one week after installing Win 10.

[Falsk Navn]

Yep - Mine went today a few days after installing.

[IT Figure]

Yes my WD 500 GB Hard Drive died as well after i upgraded to Windows 10. I used the option under Windows 10 Upgrade tool to download .iso file. After the .iso was downloaded I right clicked for properties to see the size of the file, this is when my hard drive crashed. Now hard drive won't boot and I can't format the Hard Drive, but Hard Drive is being detected by BIOS. This fairly new drive, strange.

[dr_smackdab]

5TB seagate GPT (not even the system\boot drive) only a few months old.
Win 10 update completely corrupted the partition table.

No, it's not strange. It's WD.

And to the OP: if your laptop can't see HDD it's probably dead. You can pull it out and check in other computer or with USB-SATA cable. And no software has anything to do with it, HDDs are dying. Even more often than few years ago.

Perhaps not the entire drive, but in my case the upgrade certainly corrupted the GPT. 3 month old drive running perfectly prior to upgrade, disk visible in bios and device manager. but w10 was unable to mount or assign a drive letter. Don't be so quick to dismiss this.

[micockissoft]

mine is dead also , what a pile of crap windows 10 is !

[drusome]

I'm so disappointed with Windows 10 so far. I installed it on a separate hard drive from my win 7 drive to make sure there would be no problems and it still found a way to scan and corrupt that Win 7 drive! I've spent all night trying to fix it with the win 7 RE but no joy. I use enterprise class drives and scan them regularly. While I do realize that drives can go bad, there were no issues before I installed W10. There are an awful lot of posts reporting hard drive corruption with Windows 10 right now. What did Microsoft do differently here? Why did they release a product that is breaking working drives? I will give it another chance because I have to. I'm sure in time it will be a good product, but Microsoft lost the chance to win back some goodwill with this release.
