Hello,


Every time I boot mac mini 2011 the boot manager appears. I have tried a lot of things but nothing worked. Can you please help me in order to get rid of that screen? If I reboot the mac mini remotely or power goes off and then restarts it stays on that screen that you have to click on the boot disk to load. :(

I don't use bootcamp, I just have two hard disks. I had done clean install it worked for a while but suddenly boot manager appeared again without installing or modifying anything.

"I have tried to set startup disk the SSD, unplug mouse/keyboard, repair disk, repair permissions but it stil it doesn't boot. Everytime I have to choose between mac os partition and the recovery partition. Resetting nvram is not working. I have tried it but it's just not working , I hear the startup sound once and it loads the startup manager or the recovery (I think it's capturing cmd-R as input).

In sys prefs at "Startup Disk" Mac Os is selected but If I click restart at next boot it will load mac os fine. Next time the Startup Manager pops up again."
 
Still I have this problem without any solution and none knows how to solve it.

Am I the only one with mac mini 2011 lion that has this problem?

There isn't any way to just set the default disk to boot always from that one and avoid the boot manager to run at startup?

What is the "Windows" disk displayed at the boot manager disk? I never installed windows or bootcamp or anything. The disks were 100% formated without any partitions before installing lion.

Have you verified that in System Preferences you have a disk selected in Startup Disk?

Yes it's selected and only one disk appears in System Preferences to select.

Any solution for this issue??

Hi,

Do have found any solution regarding this issue yet??

I have a new Mac Mini 2011 with two harddrives included (SSD and HD)and the problem with
the Bootmanager.
 
May be I have a solution for this issue with the bootmanger.

I have just creat a new user for the daily work. The new user is not an admin! For admin activities I have an other user that is not selected as start user.

Now my macmini starts without any problem and the startvolume is fixed.
 
I have the exact same problem on my iMac (Late 2011?). I have tried erasing the disk and reinstalling Lion and it did not fix the problem.

Edit:

I did have bootcamp installed but then uninstalled it. Did not fix the problem. This was before I tried reinstalling Lion.
