I am suspecting my Win 7 Home has some hard drive issue, probably bad index. According to this thread, I was wondering if it's possible to use a Win 7 Ultimate CD to repair Win 7 Home.

Yes, more-so if it's a startup issue. But the install DVD has to be matching your system in bit-version. ie, 32-bit vs 64-bit.
There's no harm in trying. If the disk sees the installation upon Repair, go for it.
