same problem here, i have a sony vaio vpcf1, and booting ubuntu 10.10 from an usb drive gives me the "Unable to find a medium containing a live file system." error.
this also happens when i turn acpi off - so thats no fix for me. i also get a lot of "/init: line 7: can't open /dev/sr0: No medium found" errors -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/543875 Title: unable to find a medium containing a live file system -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
