bigbalaboom Posted November 21, 2014 Share Posted November 21, 2014 Hello everyone My Mavericks has been booting from Grub2 and running perfectly on my PC for a year. A few days ago I wiped and re-partitioned my hard drive, and re-installed all the operating systems. Mavericks was installed just like before and can be booted from USB drive without any problem. But when I tried to boot from Grub2, I first got a ramdisk/preboot.dmg error (after choosing OS X from Grub2 menu) and then a AllocateKernelMemory error (after choosing OS X from Chameleon menu). parttool hd0,1 hidden+ insmod hfsplus set root="hd0,5" multiboot /boot------------- SOLVED!!!

bigbalaboom Posted November 22, 2014 Author Share Posted November 22, 2014 well, after hours of testing, I finally found that the problem was caused by hiding my BOOT partition (Grub2, fat32). parttool hd0,1 hidden+I remember I had this command before, not sure why it's causing problem now. But anyway, everything works fine after removing it. Link to comment Share on other sites More sharing options...
