I installed Ubuntu 16.04 from live USB, Installation was successful. But after restarting and selecting Ubuntu option, a blank purple screen showed for a few minutes, and then I got this error
error:failure reading sector 0x53c49260 from 'hd1'
alloc magic is broken at 0xc79b7400
aborted.press any key to exit.
What is wrong and how can I fix it?
GRUB version 2.02~beta2-36ubuntu3.2
Windows 8.1, Ubuntu 16.04
