Yosemite USB not detected
1 1

Question

Hello to all,

I am facing a problem to start the installation of Yosemite Zone on my laptop using either the DMG or the ISO file.

I have tried to create a bootable usb using Transmac, Win32discimager and Boot Disc Utility either using the DMB file or the ISO. When i try to boot from USB the USB is not even detected by my computer and it automatically boots into windows. I have also tried Mavericks with the same results. I have spent more than 4 days searching about this but no one has a clear answer. Could you please help me on this?

 

Thank you in advance: Here are my laptop's specs:

Ok, i have an update on the above. I have created a bootable USB with bootdisk utility and i used multipartition. Then went to the first partition on folder EFI/BOOT and renamed the file: "BOOTIA64.efi" to "BOOT.efi".

After restart i was able to boot to clover. Now i am extracting the HFS from Yosemite.Zone.dmg and i will restore it on the second partition of the drive. Hopefully it might work.
