(1) Yep, we have the same Installation USB drive capabilities.
(2) Enter the following command (if you don't already know this info)...
WMIC computersystem get Manufacturer, Model
C:\WINDOWS\system32>wmic computersystem get Manufacturer, Model
Manufacturer Model
Dell Inc. Inspiron 3542
Then, look up your Boot Menu F-Key here...
Get access to BIOS settings & Boot Menu: F-keys/Hotkeys by System Manufacturer (OEM)
Insert a bootable USB drive, reboot, press & hold that F-Key at (or shortly before) the Manufacturer's logo -- & you will get a list of devices to boot to. The USB drive will likely look like "UEFI: name-of-USB-device". Select that to boot to it. Try it.
That will constitute a one-time boot to the device, leaving the HDD ({bootmgr}} on top (once you get it there). It is best to boot to the USB this way especially when doing a Reset or a clean install, because those will want to do an automatic reboot -- & that reboot must be to the HDD (not back to the USB). But it's always best to have the HDD on top.
(3) Do you know what's in those "new volume" partitions? Let me see...
DIR D: /a
DIR E: /a
I hope they have nothing to do with RAID.
(4) Have you backed up your files using Notepad as I wrote earlier?
