I built a new system recently. Started out with a WD SATA 7500 HD 750 GIG. Installed Ultimate onto it. Worked fine. Added a WD 10000 HD 150 GIG and installed Ultimate onto the new (fast) drive. Now I get a dual boot, both vista. If I boot into the 10000 Vista installation I can't repartition the slow drive. If I use Killdisk (mentioned in a previous post) to WIPE the slow drive, and then re-install Vista to the fast drive, will both problems go away. Any advie much appreciated. For what it's worth I like Vista. Thanks Robzzz

You can't get Vista to wipe the old drive because the boot routine -- for your dual boot -- currently resides on the old drive. It's like asking it to chop itself off at the knee .... LOL I suggest you remove the old drive & leave the new drive in place. Then run a Startup Repair via your Vista DVD to fix the (new drive) system's bootloader.

Okay well before I read the last post I did in fact use Killdisk on the Old drive and sure enough doing that was the wrong thing to do. In any case I re-installed Vista onto the new drive which seemed to go okay except it now won't start up unless I have the Vista DVD in the DVD ROM. I tried doing a repair from the DVD but that didn't help. Any way out of this mess? Robzzz

You need to go into the BIOS and set your new drive as the boot device. THEN build the MBR on your new disk, either from the repair tools included, or by doing a repair install.

Thanks for the advice. Everything was a big help. What I did was to disconnect the slow drive. Re-install Vista on the fast drive and then reconnect the slow drive. Should have been obvious from the beginning I suppose, but the trick I guess was to disconnect the old drive first. Thanks again! Robzzz
