    Not his fault, it's due to a change in the grub package from 12.02.1 to 12.04.2. I have just updated Boot-Repair.

    @gukenschlaven: please try again tomorrow.

    Re: [Boot-Repair] Graphical tool to repair the PC boot in 1 click!

    Hi I have a MacBook Pro with retina (10,1) and have OSX, Windows 8 in Bootcamp and more recently Ubuntu 13-04 booting through rEFInd.
    I suspect I must have been booting from the EFI-stub loader? - maybe as grub never showed up anywhere during boot even though 13-04 boots fine.

    I didn't like having no apparent method of getting to the grub menu so I decided to see what boot-repair had to say about it.
    I ran the boot script part of it and got this http://paste.ubuntu.com/6037492/
    There are a couple of odd looking bits (to me) one of which is near the end which says that I might want to consider installing rEFInd, which is curious as it's already installed.
    Also there are a couple of entries that say " Please report this message to boot.repair@gmail.com"
    Another says "Please do not forget to update your main bootloader!"
    Both of which left me scratching my head.

    Anyway, I wanted grub to appear at some time during boot (for entering boot prompt purposes) so I went to the Grub location tab and checked the “Separate /boot/efi partition” box and hit apply.
    Everything went well up to the end when a box appears asking " buggy-kernel detected. Do you want to activate [Backup and rename Windows EFI files]?" and boxes for Yes and No
    I still have this on my screen and I have not rebooted yet
    Any ideas?
    Thanks.

    EDIT perhaps I should say that rEFInd was installed previously through OSX rather than lately through Ubuntu.

    @Quackers
    Not sure how often Yann checks this thread. Often I just reply but do not know Macs. I do know with Windows you have the issue of Windows on MBR with gpt or you do have to be careful to keep them in sync.

    Some interesting info here as I thought Ubuntu using the new UEFI did not work in UEFI mode with Macs as they have an older UEFI implementation.

    Ah, I see. Thanks oldfred.
    I'll browse through those links.
    I'm definitely on EFI and GPT not MBR.
    My present concern is whether to answer yes or no to the screen prompt and what the implications are of either.

    The backup & rename just copies boot files to system and for Windows will rename the efi files. Not sure on your system what rename it might do. I think I would want my own backup of the efi partition (which Boot-Repair is probably doing anyway).
    The issue with Windows was that some systems had modified UEFI (against UEFI standards) to only boot the Windows efi file, so it renames it/EFI/Microsoft/Boot/bkpbootmgfw.efi and makes grub2's shim file to have the Windows name. Then from grub you boot the Windows backup file. But it seems most systems will boot shim, but some only with secure boot on, others with it off.
    Not sure any renaming is even required on a Mac.

    Thanks oldfred. I'll answer no, reboot and see what happens after trying to boot all 3 systems, LOL.
    Wish me luck!

    Well that was an adventure!
    Rebooted in to the new refind entry for Ubuntu (EFI blah blah) got to the new grub menu and all went well - Ubuntu up and running.
    Rebooted into Windows 8 and that was fine.
    Rebooted into MAC OSX and that was good too.
    Rebooted into the new Ubuntu again and now it hangs at INFO @wl80211_attach : IWCFG80211 phy
    WTF?
    And so does the old Ubuntu entry too - same point.

    Scratching my head now

    It will let me boot the recovery entry in grub's advanced list (for the current kernel) and to be honest it seems to boot fine to a usable desktop.
    The normal boot sequence through grub just hangs at the above point.

    I think the main difference with recovery now is that it auto-includes nomodeset and no splash or quiet settings.
    What video does a Mac use. Internal Intel or another?

    Another update
    Strangely if I enter the grub advanced options for Ubuntu and select the recovery option and then select the resume normal boot the system boots ok but if I try to boot the normal first entry in grub for the current kernel it hangs at the above point. I have no idea what's going on, but at least I can get to a normal desktop by this odd route.

    EDIT oldfred, this one has a i915 onboard Intel graphics (but I think that is now disabled) and a nvidia GT650M which is the one currently in use.
