Hi all,

I've spent the past day and a half trying to figure out how to upgrade my 128GB SSD to a 256GB SSD on my Lenovo T420S laptop, and getting a teensy bit frustrated at this point.

Here's what I've done so far:
-Used EaseUS Partition Master to clone the old SSD to the new one. The primary partition drive letter changed from C: to D:. This also created about 110GB of unallocated space in a non-adjacent partition to the primary partition
-To merge the primary partition (D:)  with the unallocated space, I used Aomei Partition Assistant Home Edition. So now the D: drive has about 220GB capacity
-At this point, I just tried swapping out the SSDs and putting the new hard drive to the top of the boot order, but the computer didn't boot up. It would just stay on a black startup screen.
-After reading some more, I downloaded the ISO for Windows 7 Pro SP1 and used Windows 7 USB/DVD Tool to put the installation files onto a flash drive.
-Also note that my BIOS is already in ACHI mode since the previous hard drive was also a SSD
-So I plug in the new SSD as the internal hard drive and plug in the flash drive. I change the boot order so it boots from the flash drive. I choose 'Repair', and it says there's an error it needs to fix, so I fix it. After it restarts, I run 'Repair' again and choose my ~220GB D: drive as the one with Windows. It repairs and can't find any errors.
-Next, I take out the flash drive and change the boot order to move the new SSD to the top position. It still can't boot and stays stuck in a startup screen.

I feel like I've checked all the forums here and elsewhere for answers, but can't find anything. Any advice would be much appreciated.

Did you copy both partitions to the new ssd? The small one at the beginning and the c drive and the master boot record to make it bootable? Most SSDs come with a clone program that does all that for you in one shot. If it's not in the package, you can probably download it from the website.

Yea theres something funky about the drive letter changing. I would definitely wipe the drive and start over with a reclone.
