i did not make changes bios boot shows correct options (ubuntu/win7), changing bios boot help?code:you can reboot computer. please not forget make bios boot on sda1/efi/ubuntu/grubx64.efi file! boot files of [ubuntu 12.04.1 lts] far start of disk. bios may not detect them. may want retry after creating /boot partition (ext4, >200mb, start of disk). can performed via tools such gparted. select partition via [separate /boot partition:] option of [boot repair].
have sda1 fat 32 boot partition @ start of disk, don't understand why adding new ext4/start of disk partition needed.
appreciate these forums. use rh linux @ work development first time doing linux install on own machine, guidance/help here.
while on grub boot line, edit remove "splash", ctrl+x continue booting.
