I have both 32 and 64 bit versions. How to get rid of the 32 bit?

[projektt]

I installed Windows 7 32 bit the first time and bought 4 gb more of ram leaving me with 6gb. Well you know 32 bit only supprots 3.25 GB of ram so I upgraded to the 64 bit and I made the mistake of not choosing *upgrade*, instead, I chose install a new version of windows. Now I have 2 window 7 on my boot and I want to delete the 32 bit version and leave my windows 7 on. How to I go about this?

I tried reformatiing with the windows 7 cd. But when I type Format D: it says cannot format removable media, but on my 'computer' it shows the 64 bit as C: and the 32 bit as D:

My CD ROM drive is Drive E:

What am I doing wrong? What do I need to do to get rid of the 32 bit version? BTW the 32 bit version on drive d is NTFS and so is the 64 bit version

you can't upgrade from 32 bit to 64 bit without doing a clean install

you need to format then install the 64 bit version!

32 bit supports 4gb of RAM, depending on the version of Win7 64 bit, you can have from 8 to 192gb of RAM support. NTFS is the file system of choice... Put your install disk back in and boot from it, when given the choice of disks, check the advanced options and remove all current partitions, then allow Win7 64 bit to be installed...

Don't forget to backup your data. They will be gone of you reformat and reinstall OS.
