Comment 28 for bug 477169

Agostino: chkdsk /r on the partition does not make any difference.

ZliS: definitely not, both installs that broke for me this way were x86, I think it works for you now, because the problem package must been fixed in the meantime, so if you do a reinstall + update to the newest packages, then you don't have a problem.
The problem is to know what caused the kernel panic so not to repeat the same thing again later.

-S3B4-: if you can keep your root.disk file somewhere else, then you won't lose your data. When you reinstall things, there are easy ways to mount your root.disk in the working system so you can backup.
