I recently got a new PC build; but my tower no longer fits my 2 TB HD. I got an HD Enclosure as recommended by a buddy of mine, and the enclosure itself works fine. Except for the fact I can't boot from it. Everytime I select it in the BIOS Boot Menu, I get the error message 'Reset and Select Boot Device'. I have tried rebooting, and using different boot options. But I cannot seem to boot properly.

Any help is appreciated.

Windows is not designed to boot from an external drive, if that is your boot drive that you removed, install it on the motherboard like it was. If it does not fit, then install Windows on a drive that does or clone your old drive to a new one. But you need to get the free space down on it to where it will fit on the new drive.


Bit confusing about what you are trying to do here, why are you trying to boot off the external drive? Can't really sort out what you are doing. Is the drive you are using setup as a bootable drive? Or did you just take an internal drive with Windows and put it in a USB enclosure and trying to get that to boot? That won't work. Windows is not made to boot off an external drive. You can boot a PE version of Windows off an external drive to do administration tasks but not a full Windows setup.

I don't know if I worded it properly, but my 2TB drive doesn't fit in my new slot. :/

Maybe I'm wording it wrong, but my old harddrive doesnt fit in my new slot for my SSD. So I'm using an Enclosure (Vantec Nexstar CX) and a Sata to USB 3.0 connection cable to hook it up. However, I cannot boot off of it, which is what my primary goal is.
 


Yes that is what it sounds like you are doing, and you can't do that. I don't get why your SSD does not fit though, all the hard drives are the same size externally. Get someone around you that knows how to work with computers to look at what you are doing. You also can't just move the drive from your old system to the new one and have it boot, you would need a clean Windows setup either way, outside of your drive not fitting in the case, which is odd.

Are you sure you have a 2 TB SSD? Those would be very expensive, are you talking about a normal platter hard-drive? What case do you have?

You're totally right, its not an SSD its a platter hard-drive I believe. I thought both were the same thing to be honest.

So I cannot boot from a USB 3.0 Sata connection? Or do you know of any kind of setup that I could?

Since your 2TB disk is HDD, it's size is 3.5". It never fits to a space that is designed for the 2.5" SSD.
Size comparison between 3.5" storage device and 2.5" storage device.

I too like to know what PC case do you use.

Only way to boot off from the bootable HDD is when you remove the enclosure and connect the SATA data and power cable to it.

I was attempting to do this same thing. I just tried putting the USB-Sata cord into the HDD on the external, and the SSD that has windows installed too into the internal port. My PC doesn't even reach BIOS in this situation. Any idea?
