This helped me save and install Ubutnu on my Retina MacBook (10,1). -- You received this bug notification because you are subscribed to the bug report. https://bugs.launchpad.net/bugs/810484 Title: USB boot from PCI card reader fails Status in “linux” package in Ubuntu: Expired Bug description: I'm consistently not able to boot from an HP EliteBook 6930p on-board card reader; same SD card boots OK when inserted into an external USB card reader plugged to the PC. This happens for both Ubuntu 11.04 and 10.10. Steps taken: 1) Created a bootable installation SD card by means of "Create a USB startup disk" on another PC running Ubuntu 2) Plugged that SD card into the on-board PC's card reader and: A) got the: "/init: line 7: can't open /dev/sr0: No medium found" and: "Unable to find a medium containing a live file system" messages B) got an initramfs prompt C) plugged in another USB device (SAMSUNG_SGH-i900) and then captured into it the output of the following commands: ls -l /dev/disk/by-path => file: ls-l_dev_disk_by-path.txt ls -l /dev/disk/by-id => file: ls-l_dev_disk_by-id.txt ls -l /dev => file: ls-l_dev.txt dmesg => file: dmesg.txt and copied the files: - casper.log => file: casper.log - casper.vars => this file was empty 3) Inserted the same SD card into the external USB card reader and plugged it into the PC; booted fine. From its shell: A) captured to the file "BootFromUSB.txt" the output of these commands: lspci lspci -v lspci -vv lspci -t lsusb lsusb -tv lshw uname -a dmesg WORKAROUND: I had to append the option "LIVEMEDIA=/dev/mmcblk0p1" to the kernel parameters in order to boot successfuly from the USB pendrive.
