I successfuly installed Yosemite Zone on an XPS 13 laptop, and now tryng to install it on a E7440.
I disabled almost every features existing from my Bios, disk to AHCI, Legacy Boot (to disable UEFI).
After booting on the key, I tried a lot of param combinaison, but the loader always "Reboot" when trying to load the menu...
Help would be very appreciate. People pointed to Clover instead, but seems to need a PhD to use it.
