Changing from Windows 8 32 bit to 64 bit

by afcal72 / January 9, 2013 11:07 AM PST

I installed windows 8 32 bit by mistake and wish to convert my OS to the 64 bit version. (My pc is x64)

I have the CD of Windows 8 Pro. One CD for the 64 bit version. However when I click on the CD app to start the set up it says that windows will not run the file.

The CD wont auto run either.

How do I upgrade ?

Create a new partition, then boot from 64 bit

You can't upgrade a 32 bit version to 64 bit, but you can install the 64 bit version in a new partition giving you a dual boot configuration where you can access the 32 bit files from the 64 bit partition.

Good luck.

wpgwpg indicates you need to set the DVD drive as the first boot device then boot the 64 bit version to start the installation.

He suggested doing this in a new partition but you could also do it for the existing partition and choose to reformat the partition to avoid having both versions installed on the drive (you need a second license for the second version) and save a considerable amount of disk space also.
