I have a Dell XPS 8500 pc, with windows 8, and UEFI, I want a dual boot with windows 8 and ubuntu 12.10(64 bits) .. then I was reading the next tutorial:
but just can't boot any live dvd, I have downloaded 3 times the ubuntu live dvd(in two differents places), and one time the ubuntu secure remix live dvd ( both in 64 bits).
My bios setup is the next (screenshot):
When booting my pc with the live dvd (only in the normal ubuntu live dvd) show this screens:
With the ubuntu secure remix never boot (as if you never insert the dvd)...
Choose any option of the menu appear the next screen with the next message error:
Error: failure reading sector 0x5b500 from cd0 (always exactly the same message with the three dvd copies) Press any key to continue
After that change the screen, and show a kernel panic message:
Kernel Panic: not syncing: VFS: Unable to mount root on unknow-block (0,0)
I need the dual boot, help please (I miss ubuntu)
