<masgushi> i am getting APCI PCC probe failed message whenever i try o boot ubuntu 15.04
<masgushi> then it goes into and says "file disk checking" or similar..and irrespective of whether i let it run or cancel it
<masgushi> only way to boot into ubuntu is by choosing systemctl default

even if i don't cancel file disk checking it goes up to 8% and then shows the black screen with the 3 options discussed above

I have a dual booted laptop: ubuntu 15.04 and windows 7
This error started showing yesterday
Few days back i had updated kernel 3.19.0-21 via system updater
Laptop specifications: lenovo g580 i5 3210m intel hd4000
