No SSD or HDD - Need to reimage

[CHS-JDS]

HP 15-DW0021CL

I opened the laptop to find it has no SATA nor HDD installed. I need to reimage, but upon pressing F11 after reboot, all it presents is "Startup Repair > Choose an account to continue" and "Forgot your password or don't see your account". Clicking the latter, presents "Forgot your password or don't see your account > This list only shows administrator accounts that have previously signed in to this pc, and does not include standard user or domain accounts. You need to be signed in as an administrator to use some repair and restore tools. If you don't have a password for any of these accounts, you can restart to try signing in to Windows to manage your user accounts." 

The problem is we can't remember what the password is, nor can we remember the 3 security answers to reset the password. There's nothing we need to save on the NVMe drive. How can I reimage it since we don't have any restore drives or disks?

Hi:

The only suggestion I can offer would be to do this...

Use the HP cloud recovery tool with another Windows PC running W7 64 bit or newer to create a bootable USB recovery drive that will reinstall W10, the drivers and the software that originally came with your notebook.

Here is an info link for how to use that utility...

What I recommend you do is to create an offline account since you don't remember your microsoft account password.
