Used these directions to create a bootable USB drive to image a new laptop. The instructions were the same as far as formatting the drive, but diverged a bit after that. It was all good, though, as that was enough to get me going with it:
To create a WindowsPE USB boot stick you need to be running Windows Vista or above
The partition must be formatted using Windows Vista/7. Windows Vista/7 creates different partition boot sector code that’s compatible with the Boot Configuration Data (BCD). The BCD is used to boot Windows PE and all flavours of Windows with the Vista kernel and later. The partition boot sector is created when the file system is formatted.
In this tutorial I’ll show you the simple steps required to create a USB stick that boots into the Macrium Reflect Windows PE Rescue Environment.
Make sure your USB stick is formatted as FAT32 or NTFS.
1.Open ‘My Computer’, right click on your USB drive and select properties
2.Make sure that FAT32 or NTFS is selected as the file system. It’s best to leave the ‘Quick Format’ option un-checked.
Note: If you receive a message saying ‘Windows was unable to complete the format’ then in some cases the format has actually finished and this message can safely be ignored.
3.Use DiskPart to set the partition on the USB drive ‘Active’.
From a command prompt type:
(In here I added the step “list disk” to identify the disk number, n, used in the next step)
Select Disk n
Select partition 1
Install the WindowsPE Component
We need to create an image of the bootable CD so we can transfer the contents to the USB stick.
1.Start Reflect, take the ‘Other Tasks’ menu option and select ‘Create a bootable Rescue CD’ The wizard opens and In the wizard window, select ‘Windows PE 2.0′ and click ‘Next’.
This is where it diverged. The version I was using had the menu option to “Create Rescue Media”, and then had Windows PE 3.1.
