I have now tried to dual boot Ubuntu & Win 7 with Windows as boot loader twice and failed! I don't know what I'm doing wrong and REALLY want to have Ubuntu!
I have an Asus N56VM, gpt disk & UEFI enabled. I can boot live cd ini EFI mode by choosing this option from BIOS. I want windows to be the default bootloader, not grub.
2nd install has caused a mess - first I deleted all ubuntu partitions from first failed install, but I didn't remove grub from bootloader-no idea how to do this. I set up UBUNTU partitions for:
storage - remaining space for data in NTFS format that I want to share between both OS)
I changed the location for the boot loader device from sda1 to the root (sda6) as advised by posts relating to dual booting ubuntu/win with win as boot loader.
When I clicked install - I got this messge "The filesystem on /dev/sda6 assigned to / has not been marked for formatting. Directories containing system files (/etc, /lib, /usr, /var..) that already exist will be deleted during the install." I assume this refers to overwriting info from first install. I clicked ok (should I have ticked the format box for / instead?) - when it got near to end of install I got an error message "An error occurred whiile restoring previously installed applications. The installation will continue but you may have to manually reinstall some applications after the computer reboots. When it finished, I was unable to log in to Ubuntu using the password I created at install and I couldn't change the password using the ubuntu recovery either - when i put in new password and confirmed it - I got "authentication token manipulation error". Additionally, when I reboot, if I use grub bootloader and choose windows I get "invalid EFI file path". I can only boot windows by going into bios first.
So can someone PLEASE give me a step by step guide as to how to proceed from here: uninstall/fix current mess and successfully dual boot Ubuntu with Win 7 with windows as the boot loader? My guess is to uninstall grub, delete ubuntu partitions and start again - I know how to delete/recreate partitions but not how to remove grub.
