<div dir="ltr"><div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif">Not sure if you are using a 32-bit or 64-bit cut of Ubuntu, but I ran into a similar issue 2 years back on a older Toshiba Core Duo laptop and using Mint 18.2 32-bit, and requiring me to turn on the "force-pae" flag in the bootloader was the ticket to success in installing Mint Xfce 32-Bit (with PAE-forced) on that old thing. Worked a treat.

empty iMac4,1 (early 2006, core duo--not '2').<br>
<br>
I can boot an external macbook install usb cd disk, but of course, the<br>
installer bails when it realizes the iMac isn't a macbook. Utilities<br>
work, and I can show hardware inventory. Internal cd no longer works.<br>
AlltThis tells me that I can boot from a usb cd if the magic is right,<br>
and that the iMac is complete and working.<br>
<br>
I have googled, created a number of CDRs with various incantations, 32b<br>
(because it seems that the efi boot programme on the 4,1 is 32b),<br>
including Matt Gadient's magic mac fix, even rEFInd on amd64. But<br>
nothing else boots.<br>
<br>
Any practical advice for an old iMac4,1?<br>
