MAC boot problem, looking for help please!

Post by 1NEWLINUXUSER »

Hi. I'm looking for any possible help getting an 8-10 year old iMac to boot from an external usb drive with Cinnamon 19.2 installed on it.

It will live boot to Cinnamon 19.2 from a usb stick drive just fine. Pressing the Option key on power up gives the EFI icon for the live boot drive and it boots right up. However, replacing the live boot drive with a different usb stick drive with Cinnamon 19.2 installed on it, upon power up and pressing the Option key there is no EFI icon so for some reason the Mac does not detect this usb drive. I know it's a good install because it boots on two other computers.

Is there some way to make this iMac detect the external drive with the installed os? Any questions or ideas would be greatly appreciated.

Thanks.

Intel-based Macs support starting from an external USB storage device’s volume that has been formatted with a GUID partition type. If you wish to boot from the drive, it’s important to format the partition as “GUID Partition Table” rather than either of the other two ahead of time when you use that drive as a bootable drive.
Is the partitioning type correct? Does the USB stick appear on OSX > "Startup Disk" as a bootable medium?

I'll try and look into all this a little later but to briefly answer your questions, not sure about partition type and no it does not appear in "Startup Disk". However, the live boot drive does!

How does a live boot operating system installation differ from a "regular" install. Just trying to understand why one shows up but the other doesn't?

Thanks!

Just for fun:
Running Multiple OSes on one computer

When you install Ubuntu (or any GNU/Linux) onto your "NewWorld" Apple Macintosh PowerPC G3, G4 or G5 computer you can choose to boot between two or more operating systems. Ubuntu installs a "boot loader" called yaboot (Yet Another BOOTloader) to allow you to select which OS you'd like to boot.
Note: Newer G3, G4 or G5 Macintoshes provide an alternate method to choose which OS boots. Hold down the option key when you turn on or restart your computer and you will be presented with a list of the operating systems installed on your computer.
If you only have Ubuntu installed on your computer, yaboot loads the "kernel" and gets things started. However, if you also have Mac OS (8 or 9) and/or Mac OS X installed yaboot allows you to choose which OS you'd like to boot into.
Setting which OS yaboot automatically loads
After you install Ubuntu you will encounter a list of operating systems when you turn on or restart your computer, and, unfortunately for "newbies", Linux is set as the default. yaboot is the application that controls this list and the list will look something like this (Note: there will be variations determined by what operating systems are installed on your computer):

l - linux = only Debian with GNOME 2 worked...
m - macos = Mac OS 9.2 (!)
x - macosx = Mac OSX 10.4
c - cdrom

etc.
This gave me so much headache about 12 years ago that I swore that in the future I would only choose the simplest variants: either OSX or Linux... :mrgreen:

Soooo, how do you get it to boot if it doesn't show up? Is there something you do on start up or does it just boot to the usb once you plug it in?
Thanks.

As I stated earlier, no the usb w/installed os does no show in "Startup Disk", but the live boot usb does. And now I know that they are all MBR!

So I guess this is going to be a huge learning curve for me 'cause although I'm familiar with the term MBR I really know nothing about MBR vs GUID vs ???, etc. However, after looking through all links & info I guess what I should take away is that possibly, just possibly, a usb drive formatted w/GUID partition might work better for this old Mac. Also, if I understand correctly, during the installation process you get an option to choose either an MBR or GUID partition. I don't recall ever seeing that step during the installations I've done but probably wouldn't have recognized it anyway!

So unless I hear otherwise I think I may try and reinstall 19.2 or 19.3 on a usb and try to set it up w/GUID partition. Any suggestions on how to best proceed would be appreciated.

But that still leaves a question in that both my live boot usb drives and both usb drives with installed LINUX os are all MBR!
Any idea why it can see & boot from the live boot usb w/the MBR partition but can't even see other usb drives?

Thanks.

I plug in the USB key and turn on my laptop . It boots to rEFInd from where I can select the live install USB key and boot to it .

Alternately I plug it in and turn on my laptop while holding down the "Option" key . In this case it boots to the Mac boot manager screen from where I select the yellow "EFI" drive .

My bootable ISO does not show up in "Startup Disk" either . It is none the less visible in rEFInd and the Mac boot manager .

I suggest that when you make your next Live install USB key that you do so via Mac OS on your iMac . Initialise and format it in "Disk Utility" before installing Mint on it .

Try using a different USB key , perhaps the one you are using has some minor fault . Also try running "First Aid" on your iMac and reboot , perhaps there is some hiccup in the system that is preventing it from booting off your USB keys .

MBR Partitioning should be fine as it's universal . I have a number of USB ISO keys for installing different Linux distros . All are MBR and my mac sees them without trouble . I even installed OS Capitan on my 2008 MacBook with a live USB ISO using MBR partitioning . The only GUID USB key I have is for installing Mojave .

Could you please tell us which version of Mac OS you are running ? It might provide some clues .

I like that idea, do the install on the MAC, why didn't I think of that? I'll give that a try soon.

In addition I've just run across rEFInd so I'll read up on installation & use. Also, I think I may have misstated where/how the two different drives show up on the Mac. The live boot drive does show up in the Boot Manager w/EFI icon and it will boot up & works just fine. But the usb drive w/installed os does not show in Boot Manager. However, as recall, it does show up in Startup Disk but it appears that there is nothing at all on it. And sometimes there is a popup w/something like "drive/device is unusable/can't read", etc.

The MAC OS is High Sierra, version 10.13.6. That's all that "About this Mac" gives and from what I understand this may well be the last os update this thing can handle. The complete system information printout is in my very first post, maybe there is something in there that could be helpful.

Anyway, you've given me homework and something to think about, thanks!
