boot0 Error: The Official Guide

Article: boot0 Error: The Official Guide

This boot0 error began after I used Time Machine to completely restore my system to a state it had been in a few days ago.

I used method #1 -- although I also got the "no such file or directory" response at first. You need to specify the currently booting disk, not the disk with issues.

After the unmount, the /Volumes doesn't exist anymore. The dd command won't work. I got an error saying no such file or dir.
If I don't unmount the volume, dd gives me a resource busy error. Please help.

If disk "USB Boot" is the disk you're booted to while typing the command, and disk "My Real HD OS" is the disk you want to boot to, then you need to type the command:

dd if=/Volumes/USB\ Boot/usr/standalone/i386/boot1h of=/dev/ [etc.]

DO NOT USE the drive you just un-mounted [My\ Real\ HD\ OS] since that disk is no longer mounted and will give the "no such file or dir" error.

I used Solution 1 successfully but now I'm getting stuck at the boot screen with the Apple logo and the spinning wheel. Any suggestions on what to do from here? :/

I had trouble getting a dual boot win/os x 10.6 on an 4k 750Gb hard drive on my Probook 4530s (not too confident with command line stuff) but I found that I could clone my old 320Gb drive with EaseUS Disk Copy. So I recreated a dual boot on the 320Gb, 30Gb for win, 250 or so for OS X, then cloned this and now can use the rest of the 750Gb for windows (not OSX though).

hello everybody, thanks for this... unfortunately I made a typo/(hit enter too fast) instead of disk0s2 I hit enter on disk0 so it applied to disk0 and now I got a

'Reboot and Select proper boot device or Insert Boot Media in selected Boot device and press a key'

I tried selecting the proper boot device with F12 but it does not help.
Also I have tried reformatting the SSD and restoring the timecapsule backup but I still get the 'Reebot and...' error

I assume I have to reverse what I did to disk0 but I don't know how.

Please help. Thanks!
