YannUbuntu (yannubuntu) wrote : invalid Windows7 EFI entries in GRUB

64bits computer with pre-installed EFI Windows 7.

Installed Ubuntu 64bits in dual-boot. GRUB (grub-efi) is correctly installed and allows to boot Ubuntu, but it does not allow to boot Windows.

Its menu shows 2 INVALID Windows entries. When selecting these entries, it displays "Invalid EFI file path" error, and returns to GRUB menu.

### BEGIN /etc/grub.d/30_os-prober ###
menuentry "Windows 7 (loader) (on /dev/sda3)" --class windows --class os {
    insmod part_gpt
    insmod ntfs
    set root='(hd0,gpt3)'
    search --no-floppy --fs-uuid --set=root EE00AEA700AE75ED
    chainloader +1
}
menuentry "Windows Recovery Environment (loader) (on /dev/sda5)" --class windows --class os {
    insmod part_gpt
    insmod ntfs
    set root='(hd0,gpt5)'
    search --no-floppy --fs-uuid --set=root B2BCAC28BCABE557
    drivemap -s (hd0) ${root}
    chainloader +1
}
### END /etc/grub.d/30_os-prober ###
