I installed Windows 7 Prof 64 bits OEM (Spanish) on my new machine. As I wanted my Windows to be in English, the web shop where I bought the DVD recomended me to download an ISO file with the same Windows version (but in English), burn it on a DVD and install it. And that I should be able to use my registration code. Location ISO: http://msft-dnl.digitalrivercontent.net/msvista/pub/X15-65805/X15-65805.iso

I've done this and everything works (I have not activated my Windows yet but I expect no problem there).

Just one thing: its startup is MUCH slower now! Have a look at my PC specs (bottom).

On my first install (Spanish), it was like:
- motherboard splash screen -- shows for a second or two
- list of found drives -- a few seconds
- the text "Windows starting" -- about a second before the dots appear
- four collored dots form the Windows logo -- a few seconds after the logo is fully formed it moves on to the login screen.

On my second install (English):
- motherboard splash screen -- shows for 15 seconds
- list of found drives -- a few seconds
- the text "Windows starting" -- shows for 40 seconds before the dots appear
- four collored dots form the Windows logo -- now it moves on to the login screen about equally fast as before.

Ones it's up and running it seems to be as responsive as before, although it's possible that I'm not noticing the difference.

I did the first install on the virgin SSD drive straight from the box. The second time I let the Windows installation program format the drive first to get rid of the old installation. I noticed that there were two partitions on my SSD: partition 1, 100 Mb, "reserved for the system" and partition 2, 111.7 Gb. I only formated the big partition, and I left the system partition untouched.

Between the two installs, I didn't open the computer so everything is connected to the same port. I did not change anything in BIOS.

Has Windows not recognized my SSD as an SSD but as a normal HDD. I suspect that Windows has not done the neccesary automatic configuration settings that it should do for SSD's (but that's just a hunch). How do I get my SSD back into its virgin state, as if it came right from the box, so I can go for a 3rd attempt to install windows. Should I use DISKPART? Other ideas are welcome.
