Windows 7: Changing from 32 to 64

Changing from 32 to 64

I have Build 7100 for 32 bit installed. I have upgraded my processor to 64 bit. I downloaded the 64 bit RC, but when I try to install directly I get the error message "this is not 32 operation." I burned the file as a bootable disc, using Power ISO, but nothing happens when I boot.

Any recommendations on how to get the OS running as a 64 would be great.

Thanks

When you download the 64-bit RC, you should have gotten an ISO file. Burn that ISO file directly to a DVD - that will create your bootable disk for you. No need to use anything like Power ISO - the Windows 7 burn utility will do nicely. All you have to do is right-click on the ISO file. The first option is to burn the file (assuming you don't have other disk burning utilities installed - then all bets are off ). BAM! Done!

I uninstalled Power ISO, because every time I right clicked on the download, it would load into the ISO program. When I right click on the program now, there's no option to burn.

Shift-Right-Click, Open with... and "Windows Disc Image Burner" should be listed.

Nope, All I've got is "Open". Followed with "Windows doesn't know what kind of file..."

Working from memory here - I think this will work
  • Place blank DVD in your burner
  • In Windows Explorer, drag your ISO file to the DVD drive
  • R-click on the DVD drive - should have the burn option in the context menu
  • Select the option to burn the disk
If that doesn't work, a little google research might be in order. Here's a link to get you started --> Burn a CD or DVD - Windows Vista Help

Run the below command

ISOBURN %FullPathToDiscImage%


i.e. isoburn "G:\TEMP\en_visual_studio_2008_service_pack_1_x86_x64wow_dvd_x15-12962.iso"

Both options burnt discs. After I (hopefully) install, I'll return to post results.
Thanks

The first option by srq yielded a disk that wouldn't boot. The second by mikinho worked great. Did a clean install and am now running on 64. Thanks for your help.

Glad I could help.

btw, ImgBurn (The Official ImgBurn Website) is a free alternative that would have worked. I'm a minimalist but ImgBurn is invaluable for when the built-in programs fail. As long as it stays bloat-free it will always have a place on my primary system.
