Windows 7: Perform Clean Install after Upgrade Install

Perform Clean Install after Upgrade Install

I originally did the upgrade install of Windows 7 from Vista to Windows 7. I am seeing that I now am running "ChkDsc" every time that my computer is shut down. I was told that I would be better off to do a clean install and reinstall programs and files. Can I do a clean install with my upgrade disc, or will I be creating additional problems ?

Thanks in advance

See the "sticky" in this same forum:

Doing a Clean Install with a Upgrade Windows 7 Version

Assuming that your problem isn't based in hardware, the clean install is recommended.

Make sure that you have drivers for your Ethernet controller on hand, in case that the Win7 installer doesn't have them. (As you don't list your system specs, I can't guess about that.)

Hello crlamb, welcome to Seven Forums!

After you have copied out or made back-ups of the data you need to save to external media, use Step One of this tutorial at the link below to do a wipe (secure erase) to the entire Hard Disk Drive / Solid State Drive.
  • Then if you do not want to create the new Windows 7 "System Reserved" partition use the outline in Step Two #2 to create, format and mark Active a single 100GB partition to do the installation to.
  • If you do want to create the "System Reserved" partition use the outline in Step Two #3 to create, format and mark Active the System Reserved partition and then create and format the 100GB partition to do the installation to.
Either way, running the "clean all" then creating and formatting the partition(s) using diskpart will get you the best possible space to do a clean install of Windows 7 to; you can always extend the Windows partition to include the remaining unallocated space on the HDD / SSD or create additional partitions after the installation completes if you choose.

Hardware Issues ???

The comment regarding "hardware issues"........The only changes to my computer have been software related, and the "ChkDsk" did not occurr with Vista...only after the upgrade install to Windows 7.

A Clean Reinstall is the remedy for these kinds of problems after in-place Upgrade. Be sure to wipe the disk first.

Other tips to get a purrfect clean reinstall - use the ones which apply: re-install windows 7

It would be a good move to Check the hard drive first with the manufacturer's diagnostic tools.

Two issues: Upgrade install of W7x86 fails and W7x64 fails to clean install
Clean installing W7 x86 is no problem. But 1) upgrading Vista x86 to W7 x86 fails and automatically rolls back to Vista, and 2) attempt to clean install W7 x64 results in BSOD when rebooting to finalize the process. Any suggestion would be appreciated.
