View Full Version : [ubuntu] Reinstalling Windows in Dual-Boot Environment

July 26th, 2011, 02:39 AM
I've installed Ubuntu on a Windows 7 PC in dual-boot mode. (But, I primarily use Ubuntu.) I use Windows only when I need to. And, I noticed that my Windows was getting slower and slower and slower. So, I decided to reinstall (format partition and fresh install) Windows 7 again. But, I heard that the boot record could get overwritten by Windows installation.

What precautionary measures should I take to keep my nice-and-fast Ubuntu intact? I do not wish to install Ubuntu again as I like all my current Ubuntu configuration and setup.

Any walk-through link or tutorial blog post would be greatly appreciated.

When you reinstall windows it will override grub - but shouldn't affect your Ubuntu installation in any other way. You'll then need to reinstall grub (https://help.ubuntu.com/community/Grub2#Reinstalling GRUB2). Reinstalling grub really isn't a big deal - I find it takes about 10 minutes.
