Hi all, a little long winded but here goes... I recently installed windows 7 (7001) on a new drive (750gb) and re-formatted my old windows 7 drive (80gb) to be used as a backup for OS X. After that the windows boot drive was not available at start-up. Here is how it went: original set up: HD (os x) Windows drive (80gb) after new drive: HD (os x) windows drive (80gb and 750gb) I had windows 7 installed on both drives and at windows boot was given two choices of windows 7. This worked fine until I reformatted the old 80gb drive to be a second mac drive and at start-up the windows boot drive was not visible only HD (os x). The windows drive is still visible on the os x desktop (all files are visible) but not under "disk startup" in the preferences pane. current set-up: HD (os x) mac backup (80gb) windows 7 (750gb) not bootable I tried booting from windows 7 disk to repair but it does not recognize any bootable windows drive. Should I go through bootcamp utility to repair the windows drive? Any help would be appreciated greatly.
