Start up Failure of Win 10 upgrade from 7

Hello Folks.

I have an Dell Inspiron N 7110 that I use for taxes and banking mostly. It’s been great the other night it got unplugged and battery drained overnight... on startup I got an error message 0xc000000f. Which has started me on the journey here. Laptop is 64 bit architecture. Intel machine i5 chip 4 processors. Lots of memory.....over 1/2 disk space empty 512 gig hard drive

Started with Win 7 Home Pro at purchase of laptop upgraded at the beginning when Win 10 Home offered way back when have had no issues updating and the laptop is up to date as of last week. I do have the original product key for win 7 Home pro it’s in the bottom of my laptop...where I think if I was smart is a great place for the win 10 key if I ever get this running again.

The laptop starts then gives me the error. I can boot into the bios all is fine there it seems.

In safe mode I have run CHKDSK no errors there. It won’t log at the end but it says No errors on disk.

I can boot into safe mode so I have tried both with and without networking
Tried several diagnostics and have got a version of win 10 connected via a usb memory stick...it lets me select an os Win 10 64 bit does the agree to license screen and then when I select upgrade or custom I pick upgrade and the computer tells me this upgrade option is not available. I have attempted a couple fixes from MS Forum based on the error message. 0xc000000f I specifically paid attention to the number of 0 as it seems to matter.

Should I try to install and use the win 7 product code ? Is the system intuituve enough to acknowledge the upgrade from there. I’d be booting from safe mode with networking?

Thoughts and apologies for posting jn General Catagory as it seemed to fit a few places?

Hi, please try this:
Boot from your bootable Win 10 install disk.

Click on 'Repair Your Computer' when you see that option.

Continue through the options until you find 'Startup Repair' and run that.

See if it helps.

If not,
Create Macrium Reflect's boot disk (free) - download and install the free program and select the option to create e.g. a bootable flash drive.

Boot your PC from that.

There's a useful 'Fixboot' utility on it that may help.

Explanation:
a. You can only 'upgrade' after booting normally and have logged in.
b. 'Custom' - start of clean installing Win 10- which would require deleting all existing Win 10 partitions.

Presently you wish to do neither.

- was the PC actively using the disk at the time- worst case, was it updating when this happened?

In safe mode I have run CHKDSK no errors there. It won’t log at the end but it says No errors on disk.

Well, that's good, but that's only a check on the file system for the used part of that partition. It's quite different to checking the physical disk.
