Clean new installation of 10.04

[jodlajodla]

Hello!
At my upgrading I got some errors, and my Ubuntu doesn't work anymore. I have installed GRUB for dual boot, first is Ubuntu then is Windows 7. My question is: How can I clean Ubuntu which I have installed and my Windows 7 need to stay untouched. There I need boot to Windows too, or just delete GRUB, if Windows stay on list at new installation of Ubuntu 10.04 .

Thank you in advance!

I can't come to Ubuntu ;) I just need new install of Ubuntu and deletion of GRUB. Then new Windows boot, and new installation of Ubuntu 10.04.

Thanks!
