There are a few basic guides:
powerex’s guide where you format with an HP tool
ziggywas’ tip to format with PeToUSB
(The following step to those 2 summaries is to just use the Acronis Rescue disk creator)
There’s only one small catch. Setting the first boot device to “Removeable Device” doesn’t include your usb stick. Boot with your USB stick and find the list of hard drives in the boot menu, then move your stick up to first place. Then go back to the boot priority menu and you should see your actual flash drive listed, make that first and you’re good to go.
Oh and FYI, Acronis can’t access the Windows network on the EEE PC, nor can it access my big external drive (which doesn’t make sense). =/
I did find this one interesting tidbit of info:
Update: For whatever reason, Acronis v10 or 11 + EeePC 900 does not like being plugged into an Ethernet Switch (hanging off a router) for Recovery – it can’t find a network or any network shares – in fact Acronis sees it as “cable unplugged”. I plugged the 900 directly into a router port, bypassing the Ethernet Switch, and Acronis found the Network. Done.
I’m plugged directly into a router and it’s still not working. But maybe using a cross-wired cable would do the trick.
