Question of the Day: Will you be subscribing to the new Disney+ R49 streaming package?
So this user struggling with the USB boot on a Z140C might not be a turkey. These systems are flaky I'm finding, having setup 4 in the past day. And yup I should be a pro at this so that's no excuse for me at least.
3 setup OK, albeit exhibiting intermittent WiFi connectivity and seem to be mostly behaving, #4 not so much ...
Getting into BIOS is a bit temperamental - by default, its on quick boot so only splash screen displays. Esc or Del key should get you in at the splash. Lots of odd things enabled by default like NVMe and SATA and PS/2 enabled on a device that looks to support neither but we digress.
You can disable fast boot in boot section of BIOS to see more of what's happening on boot.
There is a USB support setting in there with a chicken and egg problem - basically in default mode USB devices wont be available until *after* OS boot, just great for a BSOD'd system but anyway. Full initial IMO should be the one - as that claims to support USB at post level, but clearly its not that simple either ...
In the BIOS setup you can select your USB device - naming is a bit convoluted so might show something like USB device partition 1 but good luck getting it to actually boot. Tried legacy mode, UEFI, various flash disks with different bootable partitions, didnt wanna know.
Then tried a USB external DVDROM which did boot a vanilla Windows 10 install CD so at least *something* worked. Doing a OS reinstall (given that the reset didnt work) results in an install failure part way with a kernel security boot failure. Get same issue whether TPM and secure boot enabled or disabled.
Appears that all built-in networking including the WiFi on this thing runs over USB. It is temperamental - at least to Aruba APs.
Methinks a bit of a lemon model, so you get what you pay for sadly. Time to RMA #4 and make it supplier's problem.

Here's my steps to do an actual Windows install directly from a physical disk (HDD, SDD).
The physical disk needs to be connected externally (or internally as second drive) to a PC/Laptop to complete the required commands.
Copy the following from a Windows 10 ISO to drive:
boot (folder), sources (folder), bootmgr (file)
Commands in sequence:
cmd > admin
diskpart
list disk
select disk (number) (select the correct disk, which is the disk where files are copied to for the installation)
list partition
select partition (number)
active
exit
(drive letter):\>boot\bootsect.exe /nt60 (drive letter):
example: D:\>boot\bootsect.exe /nt60 d:
Slap the drive back in the laptop or PC.
Boot from drive. Windows setup will start.

Wow did not expect to get a post on MyBB with the exact issue I have, with the exact same laptop, nice to know it is not me going mad. Will try advise from "tera" now
If it goes into Windows 10/11, you can access the BIOS by holding SHIFT when you click restart until the recovery menu comes up.
They have really crappy wifi, have to restart constantly to restore wifi & bluetooth connectivity. Only once they've been in standby or shut off. Restart fixes it every time it seems.
Let me know if you can figure out the cause, I'd be really interested.
