My USB Flash drive does not boot

A few things to check.

  1. Is the correct boot.efi present on the "recovery" partition? The md5 checksum for the correct boot.efi is
md5sum boot.efi
280323d8700e4cfef15116f7e50590e3  boot.efi
  1. Does the "recovery" partition have the correct GUID? While you can't see the GUID value, the patched parted should show the "atvrecv" flag which indicates the correct GUID.
sudo parted -s /dev/sdb unit s print

Model: SanDisk Cruzer Micro (scsi)
Disk /dev/sdb: 501759s
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number  Start   End      Size     File system  Name     Flags  
 1      40s     69671s   69632s                primary  atvrecv
  1. Does the "recovery" partition have the proper files?ubuntu:~$ ls -l /media/Recovery total 6148 -rw-r--r-- 1 999 999 298800 2008-04-27 22:00 boot.efi -rw-r--r-- 1 root root 231 2008-03-15 23:31 boot_linux.sh -rw-r--r-- 1 root root 68619 2008-03-01 11:27 BootLogo.png -rw-r--r-- 1 root root 536 2008-03-16 18:05 com.apple.Boot.plist -rwxr-xr-x 1 root root 5912292 2008-04-26 20:49 mach_kernel -rw-r--r-- 1 root root 57 2008-03-15 23:31 patchstick.sh drwxr-xr-x 1 root root 4 2008-01-26 13:22 System }}}

Did you force a "recovery" boot by holding the "menu and "-" buttons down on the Apple IR Remote?


= X11 fails to launch = X11 fails to load, you make changes in "/etc/X11/xorg.conf" to fix the problem and X11 still fails to load. WTF. X11 seems to be ignoring my changes.

Some Linux installers will place "/etc/X11/xorg.conf.failsafe" for X11 to use if it encounters a failure in loading "/etc/X11/xorg.conf". Sometimes this failsafe is not correct and will also fail to load. Look at the "/var/log/Xorg.0.log" and you might see this {{{ (++) Using config file: "/etc/X11/xorg.conf.failsafe" }}}

Once X11 starts using the "/etc/X11/xorg.conf.failsafe", it becomes "stuck" using it and will not use "/etc/X11/xorg.conf".

The solution is to "sudo rm "/etc/X11/xorg.conf.failsafe". Now you can fix "/etc/X11/xorg.conf" and move on.
