I had posted before about trying to set up dual-boot between Vista and XP using OSS and OSS not detecting either the Vista or XP OS partitions. MudCrab was very helpful in getting that working. That was on a test PC just to make sure I knew what I was doing. I'm not working on the real PC and I have 2 new problems. I got DD and OSS installed okay and sees the Vista partition I had installed already, but when I reboot the computer and the OSS selector screen loads up it sits at the "Processing, please wait..." screen for a full 30 seconds, then displays the OS selector, but even on that screen it "freezes" up. It's totally frozen. I can click around and press arrow keys like I was trying move around the menus and nothing happens. All of a sudden the menus in the OS Selector screen start flashing like all of the mouse clicks or arrow key movements I had done, for just half a second or a second, then it freezes again. Then it keeps doing the same thing. The only way I can boot at all is to hover the mouse over the Vista OS entry and click a couple times, then the next time it "unfreezes" it will pick up my mouse clicks and boot. I'm not sure if the 2nd problem may be related to whatever's causing the first problem or not. I made a DD Rescue Boot CD. If I boot from that CD and try to run Disk Director Full version, it tries to load for a couple minutes then comes back and says it can't find any hard disks. If I try to run DD Safe Version from the boot CD it runs fine. Any ideas? Oh, this is a brand new clean install of Vista that was installed from a retail CD-ROM onto a completely blank hard drive. I even let Vista's install routine partition and format the drive (I used the Advanced function in Vista setup to tell it how big of a partition to create, but what I'm saying is that I had not created the partition myself before starting the Vista install CD). Then I install DD10 and OSS. It installed okay and as I said above, OSS did find my Vista OS and that's available on the menu to boot from, but I have the above issues. (The intention is to then install XP onto it's own partition, but I want to make sure this is working before I go through the trouble to install XP.) Thank you!
