in my case, tried to install win7 or win xp to my lenovo e1030 using bootable usb, with default bios settings failed.
solution for my case (inside bios), is to :
1. disable usb xhci controller
2. SATA Controller Mode set to Compatible
3. Boot mode set to Legacy Support
4. Boot Priority set to Legacy First, and of course
5. Enable USB Boot and set Boot priority to designated device (in my case is the bootable usb)
hope this helps
