Hello,
I tried to upgrade my Asus Zenbook UX32VD with some Transcend SSD 720 256gb , but when I connect it to my laptop it does not boot at all ... All i get is a black screen of nothing! Bootable usb or cds does not load also when it connected (when original hdd connect everything works) . The strange thing that ssd shown in BIOS , and it also works fine on other pcs and laptops...
Contact Asus... seems to be an issue with that SSD and that notebook. Will likely need a bios update. Try upgrading your SSD firmware as well.
