Hi
Dear Jake Lo,
I have a E7440 and was trying to install Yosemite 10.10.2 with this guide https://osxlatitude.com/index.php?/topic/7478-dell-latitude-yosemite-install-guide/
i was going to install Yosemite to the same SSD as Windows is installed (i created a separate partition but in NTFS)
i passed all 28 steps of "Prepare Bootable USB Drive"
i used this bootpack Latitude_E7x40.zip 6.31MB 222 downloads
but when i restarted, booted from the usb and chosen "Install OS X Yosemite with -v -f flags" the system began to boot but at the end my dell restarted and nothing happened when it booted again i see only "invalid partition table!"
Don't know if its something im doing wrong?
please help
