Delete one OS to install another

[Old Man]

I have a system with Linux, XP and Win7 32 bit and wish to delete Win7 32 bit and replace it with Win7 64 bit, so just wondering if I can simply delete this from its partition and install the other version without problems?

TY

in what order did you install those in? is linux giving you the bootloader with the choice of OS at startup or did you use something like wubi to get the linux entry in the windows bootloader?

I used EasyBCD from Win 7...

XP and Win7 are on the same HD, while Linux is on another HD.
