I'm trying to install Ubuntu on a Toshiba laptop (not sure exact model, but it's about 4 years old, and was pretty cheap at the time). It came with windows 8, now has windows 10, and it's super slow, so I'm trying to salvage it by putting linux on it. I've installed Ubuntu many times on other computers, but I've never encountered this problem before. I get as far as the boot menu (I'm given options of "Try Ubuntu without installing", "Install Ubuntu", "OEM Install", etc. Whichever option I pick, the screen is blank for a couple seconds, then it gives me this:
[ 0.041462] Ignoring BGRT: invalid status 0 (expected 1)
[ 10.423311] ACPI PCC probe failed.
Then it just freezes, and doesn't do anything. The only way to get out is by forcing shutdown. What's going on?
I'm using a live image (14.04.3) installed with unetbootin.
