Can I clean-reinstall Win 7 on its partition without hosing down XP?

[burrbarr]

Hello gang--
I have been running Win 7 and XP Pro in dual boot per Method Two of this tutorial, without any problems.
When I tried to install SP1 of Win 7, it crashed and went back to the previous Restore Point which is
working OK for now. BUT--Windows Installer is now broken so I can't install anything from Windows Update,
including taking another crack at SP1. Can I clean-reinstall Win 7 on its partition without hosing down XP?
After the install I plan to run EasyBCD to re-connect XP to the initial boot menu. Does EasyBCD handle the
writing of NST\ntldr and boot.ini to the right spots? Or do I have to save them somewhere? And where is
boot.ini anyway? Thanks--

When you can clean reinstall Win7 to its partition it should configure the DUal Boot with XP during install since it is being installed last.

Boot the Win7 DVD, select Custom install, use Drive Options to format 7 partition and install on it.
