Hello. I am a bit confused here.

I have this laptop with me which has 1 TB hdd and Ubuntu installed in it.

But I want to install Windows 7 64 bit by replacing the HDD with an SSD.

My question is if I wanted to install Windows 7 into an SSD, should I go with UEFI or Legacy mode?

Help.

Hey there, @vijay_001!

I'd definitely agree with @thx1138v2! It really doesn't make a difference for the SATA SSD and you can always change it. However, IMHO, in general UEFI is more convenient. I'd recommend you check the answer posted by @Pinhedd here: http://www.tomshardware.co.uk/answers/id-2290701/uefi-legacy-boot-question.html
It explains the difference between Legacy & UEFI BIOS boot in details.

It's also pretty important to remember to unplug the 1 TB HDD from the laptop while you are installing Windows onto the SSD. This will prevent any potential OS confusion in the process. This encounter could be pretty annoying and cause a lot of booting issues, so you better keep the secondary drive disconnected.

Hope this helps you...

It will depend on the SSD you install. If you install an M.2 SSD (assuming the laptop has an M.2 connector) you'll probably need to use UEFI to get it to boot. If you install an SATA SSD you can probably use either but it will depend on what the BIOS supports as boot devices. Check the laptop documentation or just try it both ways and see which one recognizes the drive.
