Do a clean install to the SSD (With the HDD disconnecte). There is a program to migrate your HDD -> SSD. Personally I prefer the Clean Instal - Do NOT have to sweat:
.. Is trim Inamble
.. Are the partions aligned
.. New uncludered registry.
Verify the Bios is set to AHCI, if not you need to change it to. There is a posibility that if it was set to IDE, You may not be able to boot to windows. You need to fix this on the HDD before procedding.
No problems booting to HDD with BIOS set to AHCI, then
Disconnect HDD, install SSD and set boot priority in Bios to the SSD
.. Once Windows 7 is installed on the SSD, windows 7 updates appled, Required drivers loaded and programs are install.
.. Test system, No BSODs and system is stable. Then,
.. Reconnect your HDD.
.. Using windows 7 Backup program create a system image of your SSD system. Put the image on your HDD (I also copy this image to an external USB drive)
- Reason. Should you at a latter date need to reinstall Windows 7 to the SSD, it's a 10->15 Min job. Just insert your Windows disk, select repair, repair from image. 10 Minutes later You are Back up and running. NO re-install windows, No re-download Win 7 updates, NO re-install drivers and software. The system is restored to exacty as it was when you created the Image.
You can now daul boot to Windows 7 on The SSD, or By hitting the Key during post that brings up the Boot menu you can boot to windows 7 that is on the HDD. Maybe a week or a month afterwards you SAY SSD working great, Then you can ditch the operating system on the HDD.
