How to completely delete a Windows 7 installation ?
- I already installed Windows 7 Ultimate 64bit to partition C: and most of my important software in partition E: (this is the main).
- Then I install another Windows 7 Ultimate 32bit to partition E: (this is the sub).
- After a period of time, I want to remove the 32bit OS in E: partition. But I want to keep the software of 64bit OS already installed in E:, too.
I have tried many way (delete all the Windows, Program Files.etc.of OS 32bit in E:, even try to delete the hidden system file of this OS) but when I start the Windows, there is still 2option of Windows appear to choose => and I want to remove this step.
Somebody tell me to format the E: partition but this is a very bad choice because tons of my software here are purchased for 1-time-key installing.
Thank you for taking the time to report an issue.
What's wrong... Please write below.
How do I upgrade my computer from Windows XP or Windows Vista to Windows 7? How do I get a product key? How do I make my computer start from the Windows installation disc, rather than the computer's hard disk? What can I try if I get a message saying there is a problem copying files? If I see a blue or black screen or a screen that doesn't change, is my installation broken? How do I install Windows 7 on a netbook? How do I fix a device, like a monitor, sound card, or printer, that doesn't work since I upgraded to Windows 7? Will my programs work with Windows 7? Can I try reinstalling Windows if my computer loses power during installation?
I've tried to use the F8 commands to fix it but nothing seems to work. I am just trying to some how get windows files that are still on my computer to work and let me re-install it.
Windows cannot copy files required for installation. The files may be corrupt or missing. Make sure all files required for installation are available, and restart the installation.
WHY THE HELL IS IT DOING THIS
You want to install or reinstall Windows. You want to recover Windows from a serious error. If your computer won't start Windows at all, you can access system recovery options from the Windows installation disc that can help you get Windows running again.
It seems as if my Windows installation says some .cab files which I try to install are corrupted.
someone who has Windows XP installed should be able to purchase the Upgrade Version of Windows 7. (Of course, all other software would have to be re-installed.)
Clicking on the link "Upgrading From Windows XP to Windows 7 (Custom Installation)" actually takes me to an article that deals with "Upgrading From Windows Vista to Windows 7 (Custom Installation)".
I called Microsoft's Personal Support team (at 800-936-5700) and they told me that if I want to switch from Windows XP (SP3) to Windows 7, I would need to purchase the Full Retail Version of Windows 7.
So: Can I, or can I not, purchase the Upgrade Version of Windows 7 if I currently have a legit copy Windows XP (SP3) installed? (PS: I am fully aware that when switching from Windows XP toWindows 7 requires re-installation of all the other software!)
