[Bug 1024383] [NEW] update-grub generates only BIOS based menu entries for Windows, even on UEFI systems

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Ubuntu Foundations Team Bug Bot (crichton):

64bits computer with pre-installed EFI Windows 7. (remark: same bug if
Windows8)

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.

It appears that GRUB creates BIOS/mbr entries when it should be UEFI/gpt
type entries.

*********************** WORKAROUND **************************

either boot Windows from the (EFI) BIOS menu, or add valid Windows entries via Boot-Repair.
