Windows 7: Win 7 UEFI installation on new SSD .

Win 7 UEFI installation on new SSD .

I wish reinstall Win 7 on my new unused Samsung 840 Pro 256gb SSD. I have a new OEM SP1 Home Premium 64 bit installation disc that has never been used.
I thought this would be a good opportunity to set it up in the UEFI mode, however I am not sure how to make sure it will use the UEFI loading.
My specs are up to date so you can see I have a very recent motherboard & CPU. I believe I will need to set the BIOS settings to UEFI in all cases where necessary & to set AHCI as well before installation. Is there anything else that I should be aware of.
I will rely on the installation to set up the partitions as needed as I don't want any special partitions.
Is there anything I need to do to the SSD before hand. Samsung provide a DVD that has cloning software on it which I would not be using, but I would use the SSD maintenance program that is also on the DVD. I assume I would run that after OS installation.
Any suggestions or warnings are most welcome, to make this as easy as possible.

Hi there.

Yes there are a few extra procedures to running on UEFI.

What is the specific reason on why you want to boot off UEFI and not a legacy bios boot? I will be honest there isn't a real difference in booting performance. The normal reason why is a MBR (legacy) doesn't support disks over 2TB and GPT (UEFI) does. If you don't understand the difference I suggest you just install Windows normally as there isn't a major difference.

Anyway if you wish to continue How to Install Windows 7 Using the "Unified Extensible Firmware Interface" (UEFI)


P.S. I'm on a GPT boot on my SSD and your specs are similar to mine and it will work fine if done correctly.

It isn't necessary to waste a new $100+ Win7 OEM copy since you could easily reinstall an existing copy of Win7 on the PC to the SSD.

During the reinstall insert the old Product Key after changing BIOS if desired to UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums
to boot UEFI DVD, delete all partitions during install.

The only reason I got a new OEM Win 7 installation disc was because I only had an Upgrade from Vista version & it was a fairly early version so required a huge number of updates after installation. Also the last time I did a clean install using it I had a hell of a job getting it activated & I spent ages on the phone to Microsoft quoting all sorts of info on the disc, eventually getting it activated.

You can use the Upgrade version license with the latest official installer with SP1 provided in Step 1 of Clean Reinstall - Factory OEM Windows 7.

On a new drive where the installer will not see an underlying OS when it boots to do the install, leave the Product Key blank during install and then afterwards do the quick registry edit Option 3 in Clean Install with a Upgrade Windows 7 Version in order to activate Upgrade version on a new, wiped or empty HD.

There should be no problem activating after doing this. You're entitled to reinstall retail Win7 Full or Upgrade to any PC you want as often as you like, as long as there is a qualifying OS which belongs to that PC or is retail and not being used during the period it qualifies for Upgrade - and it does not need to be installed at all to qualify.

Thanks to everyone who replied. I eventually decided to use the Samsung data migration program to clone the OS to the new SSD. Yes it was the easy way out, but as my OS installation was only a bit over 2 months old & still very clean it was simple & very quick.
All is now working perfectly, so I will leave it alone.
Best regards.
Bligh.

Glad you're up and running. How is the performance difference?

Thanks Greg. My previous drive was a Kingmax Client 35 240gb SSD & the new one is a Samsung 840 Pro 256gb SSD. Both are of course are very fast, but I think the Samsung has the edge.
The only reason I changed the drive was as a result of me updating the Kingmax firmware which seemed to have caused a major problem with the boot manager. It would start from a cold start up or from a shut down but would not restart from a restart boot. A check of the BIOS at this time showed that the Kingmax was not anywhere in the boot order, but it would show up from a cold start situation.
I was worried that with this condition it might fail at any time, so hence the change.

If we'd known this we would have first asked for a Disk Mgmt screenshot. Sometimes the boot manager ends up on a spinner which defeats the purpose of SSD for fast start. So you always want the all other HDD's unplugged during install, but that's not always possible to do during cloning or imaging.

What's most important is to check that the System Active Boot flags are also on the SSD so you know it is booting itself, with the System flag signifying the boot files are onboard and booting the OS, Active flag pointing to where they are, and Boot flag merely showing which partition is booting at the moment.
