Trouble booting an iMac running P9
« on: May 14, 2019, 11:50:18 pm »
My venerable Intel Core Duo iMac (early 2006, with an SSD) has been running P9 for some time (and P7 and P8 before that), but something recently seems to have broken the boot process.

(Re)booting leads to a nearly-black background, but instead showing of the Peppermint logo and progress bar reflecting a normal boot, it just sticks at that background.  Killing it by holding the power button, the next reboot takes me to a menu offering options including booting or memory tests.  My metal Mac keyboard isn't recognized until the boot finishes, so I leave it 20 or 30 seconds and it boots as if nothing was wrong.  I experience this tedious multi-step process any time I start it up.

Any guidance for a not-so-Linux-savvy user (otherwise pleased with Peppermint) willing to follow detailed instructions?

It's the 32 bit version.

Here are the results of those commands:

Okay, terminal outputs all provided...any advice on how to restore a normal boot?

Okay, hearing nothing in response to two messages, I figured I'd see if installing P10 might resolve my problem.  No such luck, so I'm still in need of some good advice.  Still trying to install Peppermint onto a 32-bit Intel Core Duo iMac (early 2006).

I can insert the P10 DVD-ROM I burned of the 32 bit P10, and run it from the disk.  When I choose install, it begins the process and I choose "erase the disk and install P10" and it comes back with a dialog box:

"No EFI System Partition was found.  This system will likely not be able to boot successfully, and the installation process may fail.  Please go back and add an EFI System Partition, or continue at your own risk."

Going back takes me into the partitioning tool, where I am lost.  It shows:

Device                                Size                    Used
/dev/sda
  free space                        (1 MB)                 unknown
  /dev/sd1/ biosgrub        (1 MB)                 unknown
  /dev/sd2/  ext4          /  (128033 MB)
  free space                        (0 MB)

Any guidance avaiable?

If your Mac can only use a GPT partition scheme and EFI booting then you're probably out of luck because 32-bit Peppermint won't install in EFI mode.
