manta307 Posted August 16, 2012 Share Posted August 16, 2012 Got hit with it on ML install to Hitachi 1TB also Vertex4 128GB SSD. I mucked about with the boot app, trying various versions of Chimera and Chameleon, checked the BIOS all over, then finally did a google and found your solution. Glory be! As a Linux user I was very pleased to find another use for it. Take a look at Mint, a great refuge for Unity non-lovers; remember that Mint started out as a modest mod of Ubuntu but now is quite grown up and apparently more popular than Ubuntu. Cinnamon is my favorite version. Link to comment Share on other sites More sharing options...

gygabyte666 Posted October 15, 2013 Share Posted October 15, 2013 You can do this using basically the same command with OS X as well. Though I suppose the reason you made this for Linux is because this error would lock many people out of their OS X install. Not to mention the fact that Linux is also universal and would even work for those people without an OS X install handy. Linux does rock something awesome. Anyways, just wanted to point that out. Nice guide. Link to comment Share on other sites More sharing options...

klotjan Posted June 17, 2015 Share Posted June 17, 2015 Thank you! This tip really helped to sort out the 4k sector issue with my 500GB Seagate SATA drive. I'm now one step closer to a functional Hackintosh build. Again Thanks! 1 Link to comment Share on other sites More sharing options...
MacUser2525 Posted June 17, 2015 Share Posted June 17, 2015 Well you have the installer you have booted and installed already so boot it again with the boot1h contained on it and instead of installing in the Utilities menu select terminal and since you will be root. dd if=/Volumes/Install\ OS\ X/path/to/boot1h of=/dev/rdisk?s? You get the disk by using diskutil list before the dd command this way no tools other than what you already have needed. Hell far as that goes since you obviously will have already booted into the install with the Chameleon boot disk/installer so you can go to the Utilities folder Terminal.app and add sudo to the command and run it from the GUI. Nothing easier than this.. Edit: To get the boot1h file you should go into the /Extra/usr/standalone/i386 (path may be wrong check your install) directory on the install that way it is guaranteed to match the version of Chameleon you have installed.

CharCat Posted November 12, 2016 Share Posted November 12, 2016 Sure sounds really simple, but where is the home folder? I Linux? In Mac? In Poughkeepsie? Thanks. At least this method doesn't require one to boot from a USB which is not always an option. Link to comment Share on other sites More sharing options...
