Windows 10 upgrade crash

After Win 10 upgrade from Win7 this error shows up
Status 0xc000000f
info: The boot selection failed because a required device is inaccessible

Tried repair, nothing.  Tried changing boot from classic to UEFI.

I can pull out the hard drive and view the data.  So far the only option is destructive re-install windows.  Any suggestions?

Do you by chance live near a city that has a Microsoft Store???   I ask because they have a  guarantee that if they can't upgrade you to Win10 you get a new laptop

With that said, are you doing the upgrade via the notification in the system tray?
But what ever you do, pull the hd and back up the data somewhere.

That's a cool offer, but 2 to 3 hours away.

Yes, I already pulled the HD and grabbed all the data.

At this point, doing a clean install is probably the way to go.
I would agree and all you need is a core install of Win7 and you'll get the Win10 upgrade again...how old is the laptop?
Although if you haven't been to an MS store...it's an interesting visit :-)
was the proper disk set as first boot priority?
download the windows 10 iso from here :  https://www.microsoft.com/en-us/software-download/windows10

and try a fresh install, since you have the backup
It sounds as if the boot order is not set to HDD?
9x0c000000f boot selection failed as required device device is not available
Normally, the computer boots from your primary hard drive, or a boot device that you have selected where the operating system is stored. If the boot device is damaged, or if the computer attempts to boot from a different device, the operating system does not start up and you receive an error message.
Please check your bios boot order is set to the HDD.
Disconnect all peripheral devices from your computer (for example: printers, memory card readers, external hard drives, and external CD/DVD drives), except the keyboard, mouse, and monitor (if applicable).
With all devices disconnected, restart the computer.
Nobus & Merete,

Thank you.  i have already set the boot priority, made sure it boots from the HD, tried Classic and UEFI.  Was on the phone with Dell Support for an hour and went through all of that.  

As said above, I pulled the HD and backed up all the user data and will do a clean install.  I'm waiting for a decision from the user if he wants to go back to win7 or win10.  

From this process, I was reminded the last date to upgrade to win10 for free is july 29 https://support.microsoft.com/en-us/help/12435/windows-10-upgrade-faq so we are cutting it close.
note that the pc may have hardware problems
normally - it should go A Ok
Scott Fell thanks for the update.
Get the media creation and save it to your USB pen drive , need a 5 gig that's all
Once windows 10 has been installed a key was given. You can re-install W10 using this USB pen after the expiry date on any system that has had it.
Choose the setup for other PC.

Want to use the free upgrade to windows 10?
Have you made recovery discs or on an external drive or flash memory or have a recovery partition?
, then recover back to windows 7.
I suspect the hardware does not support windows 10

Use UBCD software or manufactures hardware software to confirm no hardware issues are causing this problem.

Dell has built in software to check everything and that was done with no issues detected. I think it is through the bios f12 to get to it.
the inbuilt soft is a bit limited in most cases, so it is worth to test with the ubcd
After testing several times, the hardware is good.  The fix was as I sated, pulled out the HD, backed up userdata, installed the hd, then ran the os set up disk from Dell.  After that was run, I still had to install all the Dell adapters and 200 win7 updates...  

It would have been cheaper to buy a new laptop than the amount of time this type of thing takes!
