Ah, that would explain you troubles!
Alright, let's try this from another angle
Let's try to do this from a live Ubuntu session
After it downloads, you'll have to burn it to a blank DVD, since all the utilities that allow you to burn it to a USB flash drive require admin, which you don't have ATM :)
You will need to right-click the file and select "Burn disk image".
I know why you are having problems before.....
(As in why you couldn't find your C:\ drive)
It's Windows 10's stupid hybrid startup feature getting in the way
Instead of shutting down from the start menu,
Press ALT+F4 when at your desktop, and from the window that pops up, choose shut down
Then try booting the DVD again and see if you can see your C:\ drive
If not, then do the steps to burn the DVD I mentioned earlier
@Seth Yeah, coincidence. Replacing sethc is the way I've always done it. Either way, they accomplish the same thing: allowing you to launch an admin CMD prompt on the lockscreen.
Also, if it doesn't work, then please run the command "diskpart" in the CMD window,
(It will take a second to load)
And then run "diskpart list disk"
This will answer the question of whether it really is the hybrid startup feature, or if Windows PE doesn't have the driver for your chipset
Please post the output from that last command
You don't have a really high end machine with an NVME SSD or anything... right?
Grrr... I hate it that you can only edit your messages for like 15 seconds... That last command should be "list disk" NOT "diskpart list disk"
