Windows 7 x32/x64 Dual Boot

[jbseven]

I have windows 7 32bit installed on my raid 0 configuration. My brother needs 64 bit for some of his applications so I want to install 64 bit on the same drive as a secondary bootable windows. I'm not sure how.

I used Easeus Partition master to create an 80GB logical partition but can't seem to install 64 bit on that: I get:

'windows 7 setup was unable to create new system partition...'

Can someone help please?

Hello and welcome to Tom's Hardware Forums.

Was your logical Partition part of an existing extended one?

I can't remember what the difference between an extended and logical partition is...

To put it simply, windows 7 32bit was installed on raid0 500gb hard drive (2x250gb). I used easeus to shrink the partition by 80 gb and create a logical partition thats 80gb in size. This is where i want to install 64bit but can't for some reason...

You will need a new key to activate the second 7 OS!
