I write here because I can not contact support by email, i have never confirmation
My problème :
After the 1511 windows 10 upgrade, the stick does not start correctly.
I have only a black screen (after Lenovo screen) or the troubleshooting screen.
I cant restore or reset the system (error) or
restore my W8.1 system image backup: w10 tells me that he does not format hdd on which troubleshooting software is running & I must boot from an ext hdd.
Problem: I can not boot from a USB drive or usb cdrom
What is the procedure to boot on usb? I only have the choice of booting from the internal disk. I have found nothing in the bios (Bios O27KT07A).
Thank you for your help
Sorry for my english i am french.

Read the whole thread, and you'll understand what's happening. Turning off write cache for the internal SSD is the key.
You can boot from a USB stick formatted with the pre-autumn update build W10 install package from Microsoft. The link to MS's original download page is still live, I found it through searching I seem to remember. Some sticks work, some do not. This is true of all PCs due to weird spec changes that happened. If the install program detects the stick, it will work.
After installing, turn off write cache to the SSD before updating to the latest version of Windows 10. Problem solved. Do NOT turn write cache back on for the SSD or your system will become unstable.

My Lenovo however, has that exact same Kingston SSD. Perhaps they are using another one now? Unless you were looking at the SD card by mistake (which I doubt as that would be a heck of a blooper), they must be.
Most sticks where people are trying to install W10 will likely be older builds (W8, like the OP) so the thread I linked to is still very handy.

Agreed! Yes, I wondered about my SanDisk microSD card , so I powered off, pulled it out, and rebooted to be sure.
They're both SanDisks, but the removable microSD card is reported as generic. Also, you can populate the "Volume" list in "Properties" and see the driver letter assignment.
