Hello guys, I installed a Samsung SSD 250 gig drive as my primary boot drive for Windows 8, I removed the original after doing the cloning etc and it works very well it boots up in a few seconds as opposed to a whole minute with my factory HDD that I had in the HP ENVY DV7T laptop. My question is, I'd like to put the original drive into the secondary drive bay, I purchased a caddy and cable kit so I'm ready but, I know if I put it in the Laptop wont know where to boot from. I've researched on HP forums and thats no help. In my Bios only one drive shows at this time, the SSD for Windows as the Boot drive. Now if I put the other drive in that also would want boot will there be a provision in my BIOS such as Primary 0 drive or something? Will I be able to deactivate the secondary drive from trying to boot ? I didn't want to format it, as I could keep it as is with Windows 8 already on it and if need be if the SSD failed I'd just put it back into the Primary bay again. If you put an SSD into your Laptop which is smaller than the HDD you have originally you cannot use the Recovery Disks that HP gave you. I found that out, by trying to do a clean install off of the Recovery Disks, it will fail every time so I used the Samsung Cloning software and that worked great. Just hook the SSD up to the USB adapter and clone your HDD and then remove it and put in the SSD and boy is it fast. Now I'd like to put the 750 GB HDD back in as Secondary and need some of your advice and help. If any of you have a HP ENVY laptop or are familiar with my BIOS settings. I really appreciate it , I feel more confident getting the advice here rather than just slapping in the second drive and finding out the Laptop wont boot. Thanks for you time in advance, I'm using an HP ENVY DV7T, with Windows 8. I had Windows 10 and it crashed 3 times so I went back to Windows 8 and it's working just fine for me.
