A few months back, I wrote about booting Windows PE from a USB flash drive. Early versions of PE didn’t make this very straightforward, but Microsoft UK’s James O’Neill has blogged about doing exactly this with Windows PE 2.0 in his article on getting started with Windows PE – it looks like it’s got a whole lot easier.
Hopefully, I’ll get some time to have a go at this soon.
Since I wrote this, James has published a follow-up post on customising Windows PE.
