Installation failure on iMac Mini (Macmini 1.1)

Post#1 by jon.oman » 19 Oct 2014, 16:03

My original 32-bit CPU iMac Mini is getting long on tooth, and is not being supported by Apple. I decided to try Porteus on it. I can boot the 32-bit EFI version of the Porteus software from a cdrom. But, the installation to the 60GB hard drive fails.

I blew away the original OSX software on the hard drive, and repartitioned it. /dev/sda1 is about 6GB in size, and is formatted as FAT32. (I thought Porteus would install better on FAT32.) /dev/sda2 is formatted as ext3, and is about 48GB in size. Finally, /dev/sda3 is 2GB in size and is set up as a linux swap partition.

Here is debug.txt:

Code: Select all

evice: /dev/sda
partition: /dev/sda1
partition number: 1
partition mount point: /mnt/sda1
installation path: /mnt/sda1/boot
subfolder: 
filesystem: vfat
bootloader: lilo
error code: 2
system: porteus 3.14.15-porteus i686
mount details: /dev/sda1 /mnt/sda1 vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 0
full partition scheme:

Disk /dev/sda: 60.0 GB, 60011642880 bytes
255 heads, 63 sectors/track, 7296 cylinders, total 117210240 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00001bae

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1   117210239    58605119+  ee  GPT
Here is how the state of the drives look:

Code: Select all

guest@porteus:/mnt/sda1/boot$ df -h
Filesystem      Size  Used Avail Use% Mounted on
aufs            587M   19M  569M   4% /
devtmpfs        489M     0  489M   0% /dev
/dev/sr0        284M  284M     0 100% /mnt/sr0
/mnt/live/run   489M  1.2M  488M   1% /run
/dev/sda1       6.1G  283M  5.8G   5% /mnt/sda1
Can anyone tell me where I am going wrong with this installation? Do you need any more information than I have given here?

Thanks,

Jon

Download the latest version of Porteus from here: http://build.proteus.org/rc

Boot from your CDROM as you have been.
Mount the download iso file: mloop /path/to/downloaded/Porteus.iso
Copy the files onto sda1: cp -a /mnt/loop/* /mnt/sda1/
Change into sda1: cd /mnt/sda1/boot
Run the installer for linux file.

That should be all you need. Any reason why you chose EFI for 32bit? Can you explain just how 'long in the tooth' your system is?
How do i become super user?

If you are trying to use the Mac's boot loader (EFI thing) it will only boot from a blessed internal drive that is formated to HFSPlus. If one of those doesn't exist then it gives up. I would think you would need to install rEFInd on the boot drive you created for the porteus install and everytime you boot the computer hold down the "alt" key to boot into the rEFInd porteus install.
If at first you don't successed lower you standards and try again

Thanks for the replies! After some thought, I chose to install the latest 32-bit Ubuntu 14.04 desktop on this Intel Mac Mini. It installed without a hitch, without doing anything out of the ordinary. It booted up right away. I now have a workable system that I can support, unlike the Apple version of the software.

I do have two other systems that I have Proteus running on successfully. So, I can still play with it.

Thanks again!

Jon
