Hi all,

Yesterday i upgraded my Windows 8.1 to Windows 10 and everything went smoothly.

I then decided it was a good time to clean up my hard drive and install a clean version of Windows 10.

I went to Recovery and selected to remove all files and reinstall Windows.

After about 30 minutes i came back in to check how things were going and now the PC is stuck in a loop.

When the PC starts up, a screen appears saying:

"Your PC has run into a problem and needs to restart.

We'll restart it for you."

It then provides an error " Inaccessible_Boot_Device " and proceeds to restart.

It will do this over and over again.

Any idea how I can fix this?

Hi Simon,
if it were me.

1.turn you PC off, unplug for a minute or two, while unplugged I have pushed the power button to confirm all power has been drained.
2. Turn the PC back on X fingers

If no luck
3.Remove boot media (windows install) either usb or dvd reboot X fingers

If no luck
4. Confirm boot media is working, on another machine
5. Confirm problem machine is setup to boot from boot media and try again.

Good luck

He isn't talking about Boot media, as in a USB or DVD, he is saying its an Inaccessible Boot Device. i.e. its not seeing the hard drive.

Anyway, to Simon, have you pressed F8 as the computer is starting and if you haven't, you may want to try that, and go to Last known Good Configuration.

Another option is Chkdsk /r at the recovery console.

Do you have access to another machine that you can use to download and make a bootable USB or DVD of Windows 10?

Since you already had W10 installed there is now a license stored in the Windows Store for you so when it asks for a key when installing you can just skip and when it installs and connects to the net it will retrieve the key and activate. My flatmate did this to his machine last night. Worked like a charm.

I could try this tomorrow if all else fails then :)

Where would i download a bootable version thing of WIdnows 10? Is it as simple as downloading a file, putting it on a USB stick and then booting from the USB drive?

I was provided with this link which is quite helpful:

http://www.computerhope.com/issues/ch001205.htm

It states the below but i dont understand it. So frustrating... how could microsoft allow this type of thing to happen?

Inaccessible boot device during Windows setup If you're trying to install Windows or have finished installing Windows and are getting this error this could be caused by any of the below possibilities. Device driver for hard drive not loading If you have SCSI or RAID setup on your hard disk drives it may be necessary to load the third-party drivers during setup. As setup starts you should see a prompt "Press F6 if you have to install a third-party SCSI or RAID driver", press this key and make sure to load the proper drivers for your hard drives.

WHat third party driverS? How do i know whats required?

Do you have a SSD? Did you by any chance used the BIOS config to change between SATA/IDE and AHCI modes for your drives?

as Brumfondl says, because you upgraded successfully your key is stored in the cloud and you can skip the prod key screens if you install (same SKU) from ISO

he also gave you the link that lets you download and create a usb boot drive and/or ISO images.

best option, if you don't want files on disk, is to use the usb/iso and remove all your partitions and let windows create it all again. once you're back online windows will activate itself

Will give this a try and report back.

Thanks so much everyone.
