fresh install, getting critical/fatal error

[andrecs50]

Thank you for your time!

I am Installing CS50 appliance using virtualbox, just installed virtual box but when i try to open the CS50 appliance I get: "A critical error has occurred while running the virtual machine and the machine execution has been stopped."

When I re-start it, i get a pop-up page asking me to boot either Ubuntu, advanced options for Ubuntu, memory test (memtest86+), or memory test (memtest86+, serial console 115200).

I tried booting Ubuntu, but it sends me the same "critical error" message as before. When I close that window, i can catch another pop-up below it just for a second saying: "fatal error... the guest is trying to switch to the PAE mode which is currently disabled..."

I do not want to start following instructions not meant for the user, since I have very little experience with computers (just starting) and I dont want to make it worst. Files attached for reference

Invalid, not a bug.

Asside from being seriously short of memory your IMG_3316.jpg is actually telling you what you need to do. Enable PAE in the guest settings as it tell you and see if it proceeds.
