Windows 7: can't do clean install from Vista 32 to Windows 7 64

Or is it possible to do a clean install to 64 bit by rebooting from my current 32 bit version of 7? I ask because this is one option I haven't yet tried. I'm thinking it's not possible but someone may tell me otherwise.
Did you reset the CMOS using tutorial provided, check if BIOS version is current? Study the manual there.

Since you'll have to reboot to install 64 bit when you have 32 bit on there, if you want to install 64 bit Vista to see if it will follow suit to allow in-place to 64 bit Win7 then I'd consider that option if you can't get Win7 boot installed.

It is possible. What is the Vista version>Win7 version? We can workaround if they're not in-place upgradable otherwise.

Also do you have another computer to try boot installing 64 bit to test partition you create in Disk Management?

trying to upgrade to Windows 7 64 bit

Greg, I've now tried resetting the CMOS & updating the BIOS but still having the same problem. However, I've just been reading a thread you posted in about a different installation problem. In the thread you mentioned plug & play OS being set to yes in the BIOS. I took a look at mine and it was set to no. Is there any chance this could be my problem? I've changed it to yes & will try again.

Yes, thanks for reminder.

You are clearly good enough at research to work this through.

trying to upgrade to Windows 7 64 bit

Greg, unfortunately I don't have a copy of 64 bit Vista. I have 32 bit Vista and both 32 bit & 64 bit Windows 7. I do have other computers but unfortunately this is the only 64 bit one.

After several days of frustration I guess I'm ready to give up - at least for a few months. I have a working 32 bit Windows 7 so I guess I'll just decide now whether it's worth increasing my RAM to 4gb or just to 3gb. I plan in the future to increase it further still at which point it'll be time to have another attempt with 64 bit Windows 7.

Thanks to everyone who tried to help me. It is greatly appreciated. Happy new year!

forgot to add that changing plug & play OS to 'yes' didn't help.

Since you bought a retail copy you are entitled to MS tech support for this.

They had/have a policy of working any issue through to completion for cooperative customers, even elevating to research team if necessary. Always call back if you don't get a good agent.

I mention it because in the past I have gotten far more than my money's worth in tech support, and quite an education.

Let us know how it goes. We never give up here.
