[Bug 1093523] [NEW] os-prober doesen't detect Win8 but only its recovery environment

[Giulio Carli]

Public bug reported:

I got some problem during the installation of Ubuntu on a UEFI ultrabook.
I give you all the infos about what I have done:
1) restore my laptop to the factory default configuration (so only Windwos 8 was on my harddrive);
2) install Ubuntu Secure Remix 12.10 30nov2012 (64bit); here I got the first "surprise": "This computer currently has no detected operating system" and using os-prober (1.56ubuntu1) I got "/dev/sda6:Windows Recovery Environment (loader):Windows:chain", while I also should got "/dev/sda2:Window 8.....". Here you can find the Boot Info Script http://paste.ubuntu.com/1460646/;
3) so I aborted the installation and I tried to verify my harddrive partition scheme through fixparts under Windows 8. Apparently everything was fine;
4) I tried a new installation of Ubuntu selecting "Other" and performing a manual partioning. The installation ended fine. At the first reboot I was only able to load Ubuntu through the grub2. Here you can read the Boot Info script at that moment http://paste.ubuntu.com/1460627/;
5) so I performed boot-repair to get back Windows loading at the grub2 shell. After that the Boot Info Script was http://paste.ubuntu.com/1460646/ (os-prober continues to give only "/dev/sda6:Windows Recovery Environment (loader):Windows:chain");
6) at the next reboot this was what I got at the grub2 options:
a) ubuntu (that loads correctly Ubuntu OS);
b) advance options for Ubuntu;
c) Windows UEFI loader (that loads properly Windwos 8);
d) Windows Boot UEFI bootx64.efi.bkp (as c);
e) Windows Recovery Enviroment (loader) (on /dev/sda6) (this gives the following error messages: error: impossible find command'drivemap'; error: invalid EFI file path; press any key to continue (and it comes back to grub2);
