I used this guide when I could not boot from my hard drive only clover USB on legacy system.
*This guide was quoted*
Tried and tested on 10.11.6 on legacy BIOS and worked for me. Im not sure how well it works with dual boots as I only use a single OS on my hack.
There are a lot of people who experience a b0 error on their first boot up after installation. Or the bootloader immediately takes them back to the Windows installation (on dual boot).
These people probably forgot to set the MacOSX partition "Active". (Can boot from USB but not the Mac drive post install)
A common mantra provided here to newbies for setting up for installation is:
- Make the partition Primary
- Make the partition ID=AF (signifies an HFS partition)
- Make the partition Active
There is a built-in Unix utility in MacOSX that can be used to set your partition "Active". It is called Fdisk
Setting Your Partition "Active" Using Fdisk
Words in bold below are things you must type (followed by Enter).
Type
diskutil list
Verify which disk number holds your partition (disk
0, disk
1, etc.)
4. Start using Fdisk
Assuming the MacOSX disk is the first disk ("disk0"), then
type
fdisk -e /dev/rdisk0 <== use "rdisk" with your disk number here !!
Ignore the error "fdisk: could not open MBR file ..."
5. Determine which partition for MacOSX needs to be set "Active"
Type
p
Verify which partition is for MacOSX (1, 2, 3, etc.)
6. Set the partition "Active"
Assuming it is partition 1, then
type
f 1 <== use your partition number here !!
7. Save and exit
Type
write
Type
y (yes you are sure)
Type
exit (to quit)
8. Remove the install USB and reboot
