Hi YannBuntu,
After browsing the internet and trying to learn how to install Ubuntu alongside Windows 8 with UEFI I found this link
https://help.ubuntu.com/community/UEFI
and it helped me to install a nice dual boot system
The computer is a Toshiba laptop specified in this link
http://www.toshiba.se/laptops/satellite-pro/c850/satellite-pro-c850-19w/
delivered with Windows 7 installed and Windows 8 on two optical disks. It was straight-forward to make a dual boot Ubuntu & Windows system, and it was possible to install Windows 8 with normal BIOS, but I had never tried to climb Mount UEFI ...
So I set the UEFI mode (without quick boot and secure boot) and installed Windows 8. Then I booted from an Ubuntu 12.04.2 LTS install USB 3 drive, repartitioned the drive with gparted and installed Ubuntu.
The installed Ubuntu worked at once, but had no Windows entry in the grub menu (and the grub menu was not displayed at all). However, it is possible to press F12 at reboot to get a boot options menu. When selecting the internal HDD/SSD, there is a second menu, where I could select Ubuntu or Windows. So the choice was there out of the box, but not very convenient.
Then I ran a Boot-Repair USB drive (via Unetbootin) and clicked on the "Recommended repair" button, and it did its magic: The following 25_custom file was created offering three working ways to boot Windows (the last one is a rescue boot option).
Code:
#!/bin/sh
exec tail -n +3 $0
menuentry "Windows UEFI bkpbootmgfw.efi" {
search --fs-uuid --no-floppy --set=root 1A06-328B
chainloader (${root})/EFI/Microsoft/Boot/bkpbootmgfw.efi
}
menuentry "Windows Boot UEFI loader" {
search --fs-uuid --no-floppy --set=root 1A06-328B
chainloader (${root})/EFI/Boot/bkpbootx64.efi
}
menuentry "EFI/toshiba/Boot/bootmgfw.efi" {
search --fs-uuid --no-floppy --set=root 1A06-328B
chainloader (${root})/EFI/toshiba/Boot/bootmgfw.efi
}
Here is the boot-repair dump file to make the report complete

Thanks a lot for a great tool
