Thanks for all the input. Yeah its Asus Eee Pc and I was going to use Home Premium(HP) but now will use Ultimate instead.
Searching around I found these steps to enable the boot menu on my 1005HA
Turn off your netbook.
Turn it on, and keep pressing F2 repeatedly unless the BIOS screen appears.
In the Boot section, disable Boot Booster.
Plug your bootable USB key or DVD drive in a USB port.
Press F10, then Enter to confirm. The netbook will reboot.
Keep pressing ESC repeatedly until a boot menu appears.
The menu displays a list of bootable devices. Choose your USB key or DVD drive and press Enter.
Just waiting for my installation disk to arrive then I'm ready to proceed. Asus even gives a walk-through for my model with all the necessary drivers to update before and after windows 7 is installed. I hope it goes smooth!!
