Purple line on boot

[hazza_ob]

I've installed ubuntu GNOME onto my mac, it reads the disk properly, gui works properly on restart, but then 8 seconds in, it just freezes and leaves a purple line in the top left of the screen. The picture shows the OS booting into safe mode, but the error keeps occuring...

Any ideas

If Windows crashes or blue-screens on you every time it boots, you may be facing a hardware or software problem. For example, malware or a buggy driver may be loading at boot and causing the crash, or your computer’s hardware may be malfunctioning.

To test this, boot your Windows computer in safe mode. In safe mode, Windows won’t load typical hardware drivers or any software that starts automatically at startup. If the computer is stable in safe mode, try uninstalling any recently installed hardware drivers, performing a system restore, and scanning for malware. If you’re lucky, one of these steps may fix your software problem and allow you to boot Windows normally.

If your problem isn’t fixed, try reinstalling Windows or performing a Refresh or Reset on Windows 8. This will reset your computer back to its clean, factory-default state. If you’re still experiencing crashes, your computer likely has a hardware problem.

Welcome to
Debian User Forums

Ubuntu is not Debian
If you are having problems installing Ubuntu, you might be better off
asking on a Ubuntu forum,....

The same would apply to the other OS, as well. I am sure they have
forums for help with the installation.
There are also many "general linux" forums,....
Debian Support Resources
Note, there are various choices,....

Specifically Debian Forums

You are welcome here, but we do like to try to keep it "Specifically Debian"
On a Ubuntu forum, you are more likely to find more people with
experience in the Ubuntu installation process, packages , etc.
Thank you

+1 (and also to GarryR's point that Debian is not Ubuntu; Ubuntu questions belong in Ubuntu's forums)
