Fixing the boot0: error (4k sector boot problem) on WD 'Advanced Format' Drives after installing Lion w Lion Installer USB drive
These instructions you have already installed Lion from a USB installer created as described on the tonymacx86 website: http://tonymacx86.blogspot.com/2011/10/ ... using.html
1) Reboot computer with Lion installer USB drive in USB port and go to boot menu
(F12 key) - When boot menu appears, choose
USB-HDD, and when the Lion Boot Screen appears, choose the Lion installer USB drive and boot to it.
2) Choose your Language and [return]. The
Menu bar appears at the top of the screen.
3) From the
Utilities menu choose
Disk Utility. Highlight the drive you have just installed Lion on and
Unmount it (either right-click on it and click '
Unmount' from the context menu, or click on the
Unmount button at the top of
Disk Utility.
4) From the
Disk Utility menu, choose
Quit Disk Utility.
5) From the
Utilities menu, choose
Terminal. Type
diskutil list [return] and verify the
Apple_HFS disk number and partition that you installed Lion on by identifying it's
Volume Name (in my case the disk number is
0 and the partition is
2 =
0s2). This may be different in your installation and it is important that you get this correct.
6) In
Terminal, change to the directory on your Lion installer where the
boot1h file is (
/usr/standalone/i386/ ):
The name of my Lion Installer USB drive is:
Lion 10.7.3 UniBeast 1.1.0 - because of this, the name in the path has an extra \ followed by a space where ever there is a space in the Lion Installer USB drive name when it is typed in the path:
Type the path
** to
boot1h into
Terminal (No need to type in SUDO first- when you boot from the Lion installer USB drive you automatically have those rights.
Type:
cd /Volumes/Lion\ 10.7.3\ UniBeast\ 1.1.0/usr/standalone/i386/ [return] Terminal will not echo the directory
i386 that you've changed to on the command line like it normally would in a fully completed OS X installation).
** Note: In the above path, there is a space between
cd and
/Volumes, a space between
/Lion\ and
10.7.3\, a space between
10.7.3\ and
UniBeast\ and a space between
UniBeast\ and
1.1.0/
7) Verify you are in the correct directory where
boot1 is located by typing
ls [return] into Terminal- this lists the files in the directory- you should see:
EfiLoginUI,
boot,
boot.efi,
boot0,
boot0md,
boot1h and
tmbootpicker.efi. The only one you're interested in is
boot1h. If you see this file, proceed to the next step.
8) Once you've verified that you're in the directory where
boot1h is located, in
Terminal type:
dd if=boot1h of=/dev/rdisk0s2 [return]
The response in Terminal to this command will include something similar to this:
2+0 records in
2+0 records out
1024 bytes transferred in 0.088021 secs (11634 bytes/sec)
_bash_3.2#
9) In
Terminal, type:
exit [return] to logout of
Terminal. From the
Terminal menu, choose
Quit Terminal.
10) From the
Apple menu select
Shut Down - After power is off, remove the Lion installer USB drive from the USB port.
11) When powering the computer back up, enter the BIOS Setup
(DELETE key) at the BIOS splash screen and make sure boot device settings are correct to boot from your hard drive.
