[SOLVED] Two Grub boot menus on Macbook pro 7.1 efi boot

Hello
This is my first Arch post and I feel a bit of a fool for making the error I'm going to describe but here we go....
A couple of weeks ago I installed Arch as dual boot on my Macbook pro 7.1 and I'm generally quite happy with the result. I boot as EFI using Grub2 having followed instructions to make a standalone boot.efi and boot from the mac's bootloader. The boot.efi file is placed on a small macosx journaled partition that has been made bootable with "bless". I've been able to boot between the two systems using 'alt' at startup or, more generally, just leave the pc to boot into Arch.
When I generated the boot.cfg file I didn't specify ro or rw but grub added ro. So I've had the "root mounted as ro" warning since upgrading to 3.10.3-1 (I don't subscribe to the testing repository) although it was obviously an issue from the start and I was aware of it. After reading some of the forum posts today I thought I'd have a go at changing the boot parameters at startup and edit the boot menu to include rw. This worked and I didn't get the read only warning. I decided to try to generate a new grub.fcg and specify rw before generating a new boot.efi. On inspecting the new boot.cfg I noticed it had both ro and rw entries. I decided to think about what to do (thinking of removing the ro) before making the standalone file.
Anyway, I had to boot into osx for something else but when doing so noticed that I now have 3 efi boot options in the mac bootmanager. Two are grub and one boots osx. I've had a look in the forums and on the internet in general but can't find out how to remove the second entry. My guess is I've installed grub on my Arch /boot partition but can't figure out how to remove it.
Although I can boot into Arch as normal as the pc defaults to the original grub menu, I'd like to remove the additional entry if possible and would be grateful for any help.

These are the instructions I followed
grub-mkconfig -o boot/grub/grub.cfg grub-mkstandalone -o boot.efi -d usr/lib/grub/x86_64-efi -O x86_64-efi -C xz boot/grub/grub.cfg
Then in osx:
sudo bless --device /dev/disk0s4 --setBoot
I think that on initial installation I ran the command above as one and then last night ran it as two. Like this:
grub-mkconfig -o boot/grub/grub.cfg
grub-mkstandalone -o boot.efi -d usr/lib/grub/x86_64-efi -O x86_64-efi -C xz boot/grub/grub.cfg
The instructions were from:
http://codylittlewood.com/arch-linux-on … tallation/
From the apple discussion forums..
This one is a bit more tricky, surely there is another way but this one is simple and not so risky
1- burn a GParted Live CD iso
2- boot on the GParted live CD (press alt on boot and wait for the CD boot option to appear) and choose the first boot entry
3- during the boot process accept every option with its default value
4- in GParted select the EFI partition and somewhere in the menus select the "flags" entry and uncheck "boot"
5- exit GParted Live CD and boot in Mac OS
6- a new volume has appeared "/volumes/efi"
in the finder go to "/volumes/efi/EFI" and delete the "ubuntu" folder
7- repeat steps 2/3 and step 4 but check "boot" instead of unchecking it
8- exit GParted live CD and reboot
I have found the instructions above on the apple discussion forums but as noted above I'm a little wary about following them. I guess though that I need to remove the entry in the mac EFI partition which is hidden in osx but shows as sda1 in Arch.
Do you think I could mount sda1 in Arch and have a look at what's on there? From the instructions above it looks like there should be a directory for Arch that could be deleted. I presume that Arch is booting from the blessed partition on sda4. Is this correct?

Macbook Pro 6,2 EFI Boot rEFind

I have been using Linux for a while, but I am not very familiar with the booting process of Linux.
First, I have managed to get Arch booting using grub2-efi, however I would like to use the Linux Kernel EFISTUB.
I have placed the initramfs-linux.img and vmlinuz-linux.efi in the /EFI/Arch/ (which happens to be mounted on /boot) and a linux.conf in the same place containing
initrd=\EFI\Arch\initramfs-linux.img root=/dev/sda5 ro quiet
When I try to boot Arch using rEFInd (not rEFInd to Grub2 to Arch) I see that rEFInd attempts to use the settings found in the linux.conf then I get the following:
[ 0.592308] i8042: No controller found
:: running early hook [udev]
:: running hook [udev]
:: Triggering uevents....
[ 0.673673] uhci_hcd 0000:00:1a.0: Found HC with no IRQ. Check PIOS/PCI 0000:00:1a.0 setup!
[ 0.673739] uhci_hcd 0000:00:1a.0: init 0000:00:1a.0 fail, -19
[ 0.673793] uhci_hcd 0000:00:1d.0: Found HC with no IRQ. Check PIOS/PCI 0000:00:1a.0 setup!
[ 0.673849] uhci_hcd 0000:00:1d.0: init 0000:00:1a.0 fail, -19
ERROR: device '' not found. Skipping fsck.
ERROR: Unable to find root device ''.
You are being dropped to a recovery shell
Type /exit/ to try and continue booting
sh: can't access tty; job control turned off
I am not sure what most of it means, however my research tells me that the uhci_hcd is some device that the kernel cannot use correctly and the two that start with ERROR: are related to the EFI booting. Since I specified the device in the linux.conf should it be looking there and not in ''?
Can someone guide me along the correct path?
Comment reguarding the "uhci_hcd" and "No controller found" messages are welcome as well.

Hello raisdead.
I'm using an iMac (mid 2010, with i3 processor and AMD 4670 graphics).
I also have been trying to get EFISTUB boot to work and I've got it running now. I prefer it to grub.
Your log reports are OK (like mine) until the ERROR comes up.
I think you may not have got the correct UUID for your disk in the refind_linux.conf file.
If you can boot with another linux, maybe a live install disk, and run
sudo blkid /dev/sda7 (or whatever the number is for your arch disk partition)
you will get the UUID to put in your refind_linux.conf file.
In the refind_linux.conf file, the menu line I use to boot with is
"Boot default" "root=UUID=e5ead341-2bea-4933-969c-09ba528e9729 ro nosplash nomodeset init=/bin/systemd"
You might use the same but with your own UUID value, and maybe no init= value, if you are not using systemd yet (despite initial problems I recommend it).
The nomodeset is to avoid a black screen problem with the radeon video module.
My boot files are under EFI/arch353/ on the first partition on my mac. The files there are
refind_linux.conf
vmlinuz-linux
initramfs-linux.img
initramfs-linux-fallback.img
To keep this up to date when the kernel changes I mount the EFI partition (do this before the new kernel is installed, otherwise you might lose the ability to mount)
mount /dev/sda1 /mnt/uefi
make a new folder arch354 (say)
and copy over the new vmlinuz, initramfs files, together with a copy of the original refind_linux.conf
When one version isn't needed just delete its folder.
refind seems to find anything that might be bootable.
Good luck.

[SOLVED] Setting default boot partition on Macbook Pro w/ no dual boot

I'm trying to install Arch on a new Macbook Pro 13", but I fear I've become somewhat confused by all the instructions in the wiki.
I have no interest in dual booting, so I left the mac's existing boot and recovery partitions alone and set up a new filesystem and boot partition. I installed rEFInd on the new boot partition and ran refind-install successfully. Installing Arch seemed to go perfectly as well.
My issue is that when I reboot the computer, it still tries to boot from the original boot partition, which fails because OS X is no longer installed. Does anyone have anyone idea how I boot from the rEFInd partition instead?
Last edited by whitebrice (2015-05-31 04:31:21)

Thanks for the quick reply. I tried deleting the original boot partition, but I still had my problem. I ended up wiping all the existing partitions and trying again with gummiboot instead of rEFInd. It works now.

Windows 7 professional 64 Bit on MacBook Pro Retina 15 with Boot Camp ?

Hallo guys, i have a big problem with installing Windows 7 professional 64 Bit on my MacBook Pro Retina 15 with Boot Camp. No matter what i try i get a black screen after partitioning or get a message like " No bootable disk" or " No System Disk availabe".
My Mac has : OS X version 10.8.2, 16 GB RAM, 512 GB memory, 2.6 GHz Intel i7 and is only a week old
My Boot Camp is version 5.0.1
My Windows InstallingDVD is one year old now, i needed it to build a PC last year, hope that doesnt make a difference, its a full version, so not just for upgrading.
From what i saw in the apple support it should work on my macbook. I hope someone can help me.
Thanks in advance.

Ok, problem solved. I looked a bit more here in the questions and there was the answer and its quite simple.
Somehow an USB-stick makes problems while Windows wants to install, i dont know why. So i just made everything over DVDs and now everything works fine.

Can a Mac Pro boot off a MacBook Pro in Target Disk Mode?

Summary: "Are you able to boot a Mac Pro off of a Mac Book Pro in Target Disk Mode?" OR "Will a Mac Pro boot off an OS X install that was made on a MBP?"
Details:
I'm finishing a music project that was created on a PPC G5 Quad computer and going to a studio in Santa Monica to complete the final mixdown. My 3rd party software plug-in configuration is unique, and the studio doesn't have all of the software instruments that I do on their 8 core mac pro. My G5 software installation is mirrored to my MacBook Pro, but the MBP doesn't have enough CPU power to play the project back.
Is it feasible to have the studio's 8 core Mac Pro boot from my MacBook Pros hard drive? Essentially, we'd be using my OS and software on their powerful CPU / hardware. I figure, since they are both Intel builds of OSX, this should be do-able.
I don't have access to the Mac Pro until I show up to start working.
Thanks for any input / suggestions!

The MacBook Pro boots fine in 10.5.8, and loads the Logic project without any faults. The only issue is that a CPU shortage occurs when you attempt to play the sequence.
Like you suggested, I performed separate UB installations of all the needed software on the MBP solely so I could move Logic projects from one computer to the next without a hitch. (Actually, DropBox does this for me). Migration assistant was not employed in this process due to the PPC / Intel issues you noted.
I didn't need to mention the G5 as it appears to have caused some confusion based on Kappy's reply, but I did want to explain my work flow thoroughly.
It sounds like booting the MacPro from my MBP is feasible. I'll mark this topic 'solved' and head over to the studio tonight. I'll post here any anomalies from the session (if any).
THANKS~!

Hi everybody, I am in Turkey on a long assignment, I need help solving a big problem on my macbook pro os 10.9.3. The other week my wife visited some website and now we have a redirect virus of some sort, and every other time when we click

Hi everybody, I am in Turkey on a long assignment, I need help solving a big problem on my macbook pro os 10.9.3. The other week my wife visited some website and now we have a redirect virus of some sort, and every other time when we click on a link or anywhere on the page we are redirected to this casino web site, https://casino.7bets10.com/tr/?from=hy9yKXD43jSC-8Oxbw4femNd7ZgqdRLk-dHJpeG9uaXR l. Its the same whether on Chrome or Safari. Does anyone have a solution, thank you!

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
Copy a line of text in this window to the Clipboard.
Paste into the window of another application.
Wait for the test to run. It usually takes a few minutes.
Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

When I boot up my macbook pro, it takes forever to start and I got grey screen...Help Please.

Just a minute ago I tried to boot up my macbook pro...normally the grey screen pops up with the whirring wheel, and then my Lion log-in screen comes up and all is well. This time, however, the whirring wheel spun forever on the grey apple screen. Then the wheel stopped and it went to a solid grey screen with apple...and nothing for about 10-15 seconds. Eventually it came up. BTW, this was the 2nd time I tried to boot because the first time, the grey screen with the whirring wheel stayed up for several minutes so I rebooted.
Anyone know what might be wrong? Thanks so much for your input!

I have two email accounts on my MacBook Pro and iPhone. My iPhone continues to send messages from either account that I choose. My MacBook says that one of my email account outgoing mail servers is Offline? How can I get that working again?

I have two email accounts on my MacBook Pro and iPhone that I have been using for a few years. My phone works perfectly for both accounts. Now one of my email accounts on the MacBook says the outgoing server is Offline? How can I fix that so that both accounts send and receive email. I have tried various things in settings but nothing seems to work.

Hi Rochdr,

How can I have the same environment on two macs on is a macbook pro and the other a Mac mini

How can I have the same environment on two macs on is a macbook pro and the other a Mac mini ?

Forget trying to use iCloud for this - it won't do what you want. iCloud syncs certain data like contacts and events, but it doesn't sync "environments" on computers.

I deleted two user accounts from my MacBook Pro to create a third user account to consolidate all my duplicate files. Now my Mac won't download from ITunes, nor re-load music from one of my deleted accounts.

I combined two user accounts on my MacBook Pro into a new, third, user account. The biggest account in terms of my I Tunes library, past purchases, etc., was preserved. The smaller deleted acount with about 40 I Tunes purchases needed to be "reloaded" into my "machine".
I went through the procress several times, meaning, "go to purchased", items not on this machine, etc, only to receive the same message of not having permission to download.
As well, I can't download new items form the ITuunes store.
Solutions anyone?

My computer is the same I've had for a year now. I didn't have a problem until I closed the two user accounts and consolidated into an admin account.
In my ITunes account it says I have "two computers authorized to play content". There's a "delete these authorized computers" function. I'm not hitting that button until I have to.
The help desk says to delete my downloads folder in ITunes and then re-download my previous purchases (I can't find a downloads file to delete) .or reload from Cloud. I don't have cloud on my Mac.
ARGH!!!!

I own and work on two Mac computers.. a MacBook Pro and an iMac. Am I required to "purchase" the one-time in-App purchase of $4.99 TWICE, one for each computer..??

I own and work on two Mac computers.. a MacBook Pro (dual core, 3.06GHz, 8 GBs RAM) and an iMac ((dual core, 3.06GHz, 4 GBs RAM). Am I required to "purchase" the Garageband one-time in-App purchase of $4.99 TWICE, one for each computer..??

The answer to your question is not about the GarageBand content but the concept of downloading any apps (or in-apps purchases) from the app store. The Key is your Apple ID.
Whenever you download an app (it doesn't matter if you pay for the app or if it is free) you have to to be logged in to the App Store with a valid Apple ID. That becomes your "Online License". Whenever you are logged in to the App Store with that Apple ID you will see your Purchase History, what apps you downloaded and also what apps have updates available. As you see, this procedure is independent from your actual computer. The App Store is only interested in your Apple ID for verification.
To download an app or content on a different computer, just make sure you are logged in to the App Store with the same Apple ID you did for the initial purchase.
The button will now display (instead of Free or the price tag) "Install" because the App Store knows that you purchased the item before (with that Apple ID) and that you computer you are on at the moment oesn't have th app installed. Just click the "Install" button to download the app.
Here is how the Button looks like depending on the condition.
The same principle applies to in-app purchases. With GarageBand, when you try to restore Purchases, make sure you are logged in in the Apple Store with the Apple ID you made the original purchase.
One more thing: You don't need to be logged in to actually run an app, only for online activities (downloads, updates)
Hope that helps

Reinstall OS X.
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
OR
Reinstall Snow Leopard without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

I can boot up my macbook pro but all i see is the wallpaper and the dock and the toolbar at the top. I can not see my hard drive or anything else. please help

Please help. I can boot up my macbook pro and log in but after that all i see is the wallpaper, toolbar and the dock. In the dock it has 2 ? where the doc and download folders should be. If I open up a new finder window it doesnt show anything in there no hard drive or anything. If anyone konws how to help let me know please and thank you.

Agree with baltwo, though even if you have saved the install app I wouldn't use it unless its been used to install a known good copy of the OS already.
In your case, that probably means start fresh:
Restart the computer, holding down 'command' and 'r'. When the recovery disk window shows, choose 'Reinstall Mac OS X'.

MacBook Pro 2011 won't boot

My early 2011 MacBook Pro 15" won't boot. Second time dealing with this this year. Apple Store charged me $300+ to fix it the first time. It worked for a few months, but stopped working again. Took it to the shop again and asked them to fix it for good this time. They wanted to charge me $310. I said NO. why would they charge me twice for a repair I asked them to do before? How widespread is this problem? I know for a fact I'm not the only one dealing with this problem.

What have you done to define your problem? Look at this comprehensive troubleshooting article and perhaps you can find a solution:
