ASUS Eee PC 1001px
The Asus Eee PC 1001PX is a 10.1" laptop with an Intel Atom N450 processor.
The same model was sold in Europe under the name Eee PC R101.
Installation
To boot from an USB stick it is necessary to deactivate the "Boot Booster"-option in the BIOS or otherwise the Asus seems to skip all detection scans and will just boot from harddisk. Press F2 repeatedly during the fortunately short POST to enter the BIOS. Deactivate "Boot Booster" and select your USB stick as the first HDD in the HDD list. (The "Removable Device" in the main boot devices list is something different.)
When partitioning you may want to keep the EFI-partition (usually the last, smallest partition). It allows to use the "Boot Booster"-Feature and to jump over certain tests before booting. Do not panic however if you deleted it, the partition may be restored. Look on the eeePC-Forum for it.
