"OpenSUSE failed to boot post-install, UBUNTU keeps crashing."
What is the make/model of your laptop?
When you say crashing, is that a kernel panic (black screen with a dump of some registers and all controls frozen, you have to press power switch to reboot) or is it just that daft popup window that says something about internal error? If latter, it isn't serious but I agree not what you want with an unfamiliar system.
PS: At work I have a small PC with an atom processor and 2Gb of RAM. Windows 10 for Education actually runs rather well on that low end hardware. Pity about all the data swiping/corporate politics around what appears to be an actual improvement.
