Just wondering, can you put x64 Home Premium on one partition and x86 Home Premium on another partition for dual boot? Or would you run into issues since they use the same boot loader and everything?

i think it will work perfectly :-)

just install first vista then install secund on secund partition :-) they both use same Loader an

you'll have no problem :-)

you can have as many vistas as you want. just create the partitions and install each one on the separate partitions sequentially. each time, a new entry will be added.

only thing is each entry will look the same "Windows Vista". you may want to edit the descriptions with bcdedit, like "Vista Home x86" and "Vista Home x64".

I've booted XP, Vista 32-bit, Vista 64-bit, and Ubuntu from the same machine before...I strongly recommend using grub or grub4dos if you plan on doing much dual-booting, though, because you can use it to hide the OS partitions from each other and leave the boot files for each OS intact too.
