How to downgrade Windows Vista Business 64 bit to 32 bit

[attitude.ashwin]

I am having Windows Vista Business 64 bit installed in my computer and I want to downgrade it and install the 32 bit version of the same operating system. Can anyone tell me what must I buy and how am I suppose to do the downgrade of the operating system. Thanks for any kind of information in advance.

I dont think that you will be able to downgrade the operating system, however you can do a clean install of Vista. Incase you do not have a Vista Business 32 bit DVD, then you will need to get one to install it on your computer.

Yes, you will need to get the 32 bit disk and then at the startup press F1, F2 or Delete to go into BIOS/Setup or F12 to go into the boot menu. After going in that, change the boot order to DVD drive in the 1st place and insert the 32 bit Vista Disk in the DVD drive and then restart. Then you have to follow the instructions to hit any key to continue and then let it load the files and then delete the existing Vista partition and then set new parition and then format and install Vista.
