I have a Laptop (ASUS X310A, I installed Ubuntu 12.04 to be side by side with Windows 7 but I seem to have gotten a problem with booting Windows 7. I used the Boot Repair twice with no results. Boot-Repair info: http://paste.ubuntu.com/1417623/ The error I get when starting Windows 7 from GRUB is: error: invalid efi file path In Boot Manager or Menu, I have 3 options now: 2x for Ubuntu (maybe cause I did boot-repair twice) 1x Windows boot manager (If I boot this it opens "ASUS Preload Wizard", it gives me the option to re-install windows losing all previous data -) When I was making the partition before installing Ubuntu, I made the new partition by making sda4 smaller and adding ext4 mounted: "\" and adding a swap area. Installed it and it didn't work, nothing worked. So i booted Ubuntu from the USB again and deleted the partitions I made and decided to make sda3 smaller and making the partitions but this time it gave me the option that I could mount sda3 on "\windows" or "\dos" I ignored it and didn't choose neither because the I know that it doesn't need to be mounted and proceeded to create what is now sda7 (ext4) and sda8 (swap area). It still didn't work so I booted from USB and did the first boot-repair, so I was able to boot Ubuntu now but not windows, but when I did it through my USB I was not able to update boot-repair, so i decided to redo the boot-repair from Ubuntu running on the Hardisk (fully updated) and it still didn't work. In GRUB this is what i see (when booting using Ubuntu as first option in Boot Menu): Ubuntu, with Linux 3.2.0-29-generic Ubuntu, with Linux 3.2.0-29-generic (recovery mode) Windows UEFI loader Windows Boot UEFI bootx64.efi.bkp Windows 7 (loader) (on /dev/sda3) Windows Recovery Environment (loader) (on /dev/sda5) I tried all the ones starting with "Windows" they all don't work Please help, Many Thanks
