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?

I have tried setting up my CMOS so that I can boot from the DVD but I have run into some issues. First of all, when I look at my keyboard during the boot procedure, I noticed that the little light which indicates that one row of buttons are to be used for F1 - F12 keys, the little green led light goes on and off. Sometimes, during the boot process, it is on, sometimes it is off.

The CMOS procedure tells me I can hit F12 and set the boot order. I can hit F12 but when I go into that menu, I notice my keyboard is dead. The CPU does not accept any commands from me. So I need to power off and power on and try again.

The CMOS procedure tells me I can hit DEL and that launches the whole CMOS utility. There I can set the boot order so that the DVD is run first. But when I save and exit, I notice my keyboard is dead again. This time, the screen is showing things being set and loaded and I am prompted to hit any key to show I am sure that I want to boot from the DVD. I hit the Y key and I hit the spacebar, but it becomes clear that my input is ignored since my keyboard is being ignored. And the ol' Vista OS is loaded.

Please advise. Is there any way to set things up in the VISTA OS to force a boot from the DVD? I guess I can load the OS in save mode and format the C drive, but if I do that I might risk having a dead computer since the CMOS does not seem to be trusting enough to boot from the DVD drive even if you tell it to.

Microsoft has this page of links:
And then there is this link:

And the Notes section specifies that I need boot off the DVD drive:
"•To install a 64-bit version of Windows 7 on a computer running a 32-bit version of Windows, you'll need to start, or boot, your computer using a 64-bit Windows 7 installation disc or files."

So, how do I make this happen?

If you have a fancy keyboard that requires a special driver to function then you may have trouble using it for an install. Do you have a basic keyboard that you could attach?

Also if you have your computer BIOS set up with the DVD as the 1st item in the boot order then it will boot from a properly formatted W7 DVD if it is in the drive; however it is quite common for people that burn their own W7 DVD that they do NOT create it properly and then it is not bootable. So be sure you have your BIOS boot order set so it looks at the DVD first, then make sure you have a proper W7 DVD, pop it in and boot the machine from off. If the boot order & DVD are correct then it will automatically boot into the W7 installation menu without any keyboard input at all.
