I have a 2007 Macbook Pro that is running 10.6.8. I'm actually using it now to ask this question.
I also have an iMac running 10.13.6

I can't use my laptop because of it's age and because I cannot update it any more, browsers won't work properly ect.

I was advised to try Ubuntu.

As it stands now, I've got the .iso file and I've also converted it to a .dmg file by following the instructions from the Ubuntu site, however, I'm not very technical. I can follow instructions but when it comes to terminology.... I don't know a thing!

Ok, so I also burned a dvd from the iso file from my imac using Etcher. Reason is my computer will not recognise a USB stick to be bootable with. I've tried the terminal commands but didn't work.

Perhaps the disk didn't burn right? I dunno so what happens next was this.

I inserted the dvd in the drive. It didn't mount on the desktop but also didn't give me an errors.
I restarted the computer and held down the Alt/Opt key.
I got the two choices and chose the CD however the cd said "Windows".
Screen went black and was then prompted with....

Select CD Rom Booty Type:_
Keyboard wouldn't let me type anything
After googling this, I was even more confused.
Had trouble trying to restart/shutdown computer so only way was to unplug it (battery is useless).
I tried again but this time alt/opt didn't give me the DVD to choose from - the dvd actually spit out at that point. So I booted to my macOS. Re-inserted the DVD but then got an error saying that the cd was unreadable: eject or ignore.

My mac specs are as follows:

If anyone can tell me what might be wrong or if this computer can take Ubuntu I'd appreciate some help.

this computer works great! Starts up beautifully, all the keys work. The cd drive is actually new (just installed a new one, old one failed). I can't give this system up! I just can't use it because of outdated programs.

Apart from installing from CD or bootable pendrive there are couple of other option to work with Ubuntu in your system.

1. Use VMWare or Oracle VM software and install Ubuntu in it. Virtual Machines are best solutions for experimental setup.

2. Use Live USB stick.
