Good evening,
I just reinstalled W10 after a reformat, but this idiot created the system partition on the main partition of the disk in the middle; I tried to shrink it to reallocate the unallocated space, but the latter is divided into two and apparently can't be merged.
So I would like to format again to be able to reallocate the partitions, but W10 keeps booting despite the fact that I set the USB drive as the main boot device and "disabled" the other drives (hard drive and "cdrom").
Is there a command to restart the PC and force it to boot from a specific disk (namely the letter assigned to the USB drive)? Thank you in advance.

I found the solution thanks to this page in English:

Basically, it's the same method as for Windows 8. As Malekal mentioned, the problem comes from the fact that Windows OS after Windows 7 on certain configurations boot too fast and prevent booting via the BIOS to select booting from the USB key.
Assuming you still have access to your Windows 10 (or 8 since it's apparently the same method).
1) Turn on your PC and let Windows 10 start normally, then insert your USB key that you want to boot from.
2) Click on the search bar or the magnifying glass at the bottom left next to the Windows start button (or click on the "Windows Start Button" then "Settings" and finally in the search bar "Search for a setting")
3) Type and search for "Change advanced startup options".
4) Then in the - Advanced Startup - section, click the "[Restart now]" button. This will restart Windows 10 in "troubleshoot" mode.
5) In the Choose an option menu, select "Troubleshoot", then in Troubleshoot and Advanced options, and finally "System Restart Tool". There, spam your BIOS key to choose the boot (F8 for me, but it may be different on another motherboard), and this time the "Please select boot device" option appears.
6) Select the USB key, and this will launch the portable version installation menu of Windows 10 with FINALLY the option to delete the system partition (as well as the others) during reinstallation, thus managing your hard drive; (option not available when launching the application directly from Windows 10 explorer, the reinstallation takes place and formatting occurs, but the partitioning of the disk remains the same).
There you go, hoping this helps those who have been tearing their hair out with these keys that won't boot.

There is also, on Windows 8 and Windows 10, this method to access the BIOS (if UEFI): https://www.malekal.com/demarrer-bios-cle-usb-facilement-windows-10/
From there, you can boot from the USB drive or set it as the first option in the boot order.
(I had forgotten this solution).
