I am trying to set up a laptop for my son's online schooling. I bought a ASUS E1 Vision Laptop, loaded 12.04 in a partition via the USB installation. But when it reboots, it will only go into windows 7. I've made sure the Bios is up to date. But the BIOS doens't even see the boot partition for Linux. But in the W7 environment, I can verify the partition was successfully created for Ubuntu. I tried the install on another netbook I had laying around and it was successfull. Any ideas on who to remedy this?
