I am trying to go from 32 bit Vista to 64 bit Windows 7.

The 32 bit Vista was installed by mistake. My system can handle a 64 bit OS. Now I have finally found the time to upgrade. But the 64 bit intallation DVD can't be read from my OS. Any Advice?

Do I need to boot from that DVD drive? Will that work?

Yes..
It may take up to 15 gigs on install..Give it a lot more space than that because many softwares still only work if they install to program files in the primary live partition on C drive..
That is where you'll be putting 7 on..

Btw 7 - 64 will make program files twice..one will be program files 86 ( it will says that this is what it is )..the other will be program files 64 ( it won't say 64 )..programs will find the correct one to install into ..


Unless you want to format your HD ( if you only have the 1 HD ) install 7 next to Vista ( not over it ) ..Later recover whatever files you want from the Vista partition..

You can then either "extend" the live partition with 7 installed .. or keep the old vista space for storage ( after formatting that vista partition )..

Better still, is install 7 on it's own HD..and keep your files on at least one other HD..or more

Make sure that you have at least 4 gigs ( 8 and up is better )..of RAM for a "vanilla" 7-64 install..otherwise it may run like molasses..

you can't upgrade from 32 to 64.
boot from DVD, format, clean install.

as lego said get all your stuff off
