Created attachment 353594 [details, diff] ebuild bump patch Versions of os-prober >=1.58 add EFI support, to detect MS windows bootloader & elilo on the EFI system partition, commit is here: http://anonscm.debian.org/gitweb/?p=d-i/os-prober.git;a=commit;h=27b6da60440ab6b6b11e63621fabee482dbb6cbf It would be great to just bump to the latest version 1.62 that includes additional fixes, I have attached an ebuild diff that makes sure the new efi/ subdir is installed. There may be a cleaner way to integrate this into the existing install logic, but this change does work here. With this bump, now I get: # os-prober /dev/mapper/control: open failed: No such device Failure to communicate with kernel device-mapper driver. Check that device-mapper is available in the kernel. No volume groups found /dev/sda1@/EFI/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi # And we just need a minor patch to grub-2.00 to get this fully integrated there.
Bumped adding support for EFI, thanks.
