I have an hp ENVY 15- j003cl in which I have replaced the 1TB 5400 rpm HDD with a 500GB Samsung 840 EVO SSD. After the SSD used a portion of it's storage capacity for some feature, and the OS took it's part including the recovery partition, I have about 380 GB of storage capacity. I have decided to add an additional 250GB mSATA SSD in the available mSATA slot. Upon instalation and boot, the system must have looked to the mSATA SSD for the OS (which isn't there) and would not boot. Attempts to change the boot order were unsuccessful as the option isn't there in the bios. I would really just like to use the mSATA SSD as secondary storage because I don't have the ability (that I know of) to transfer only my OS onto it, leaving the data on the larger SATA SSD, plus, since they are both SSDs, it shouldn't really matter. Any suggestions?
