How do I install Windows 10 from USB to a UEFI Secure Boot Machine
FYI.. Best tool I have seen for Windows for creating a USB Boot Disk from ISO is - Rufus: https://rufus.akeo.ie/ and works great. There are some helpful USB tools in LINUX Mint - but, that is out-of-scope here. ;)
Overview from the Site:
Rufus is a utility that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc.
It can be especially useful for cases where:
- you need to create USB installation media from bootable ISOs (Windows, Linux, UEFI, etc.)
- you need to work on a system that doesn't have an OS installed
- you need to flash a BIOS or other firmware from DOS
- you want to run a low-level utility
Despite its small size, Rufus provides everything you need!
- First make sure your bios has secure boot turned on.
- Next, build your USB stick with Fat32
- Then install normally.
The 11 steps for manually preparing / building a USB Disk to be a bootable Win 10 Install. This bootable USB stick will work for both older BIOS installs as well as the newer UEFI installs.
- Diskpart (Run from a CMD prompt)
- List Disk
- Select Disk # (Where # is the number of your USB disk)
- Clean (removes any partitions on the USB disk, including any hidden sectors)
- Create Partition Primary (Creates a new primary partition with default parameters)
- Select Partition 1 (Focus on the newly created partition)
- Active (Sets the selected partition to an active valid system partition state)
- Format FS=fat32 quick (Formats the partition with the FAT32 file system. FAT32 is needed instead of NTFS so that it can load under the secure boot UEFI BIOS.)
- Assign (Assigns the USB drive a drive letter)
- Exit
- Copy all the files from the Windows 10 isO to the USB Stick.
