I have Disk Director 10 and activated OS selector. I have 2 sata drives. The first drive has Windows XP, the second drive is data. I created a second primary partition on the first drive, that's where I want my second copy of XP. I reboot to oss with my Windows XP CD in the drive. I right click the CD icon and tell it I want the newly created partion to be active and I want the partion with Windows XP on it to be hidden. I double click the CD icon and the Windows XP setup program sees the new partion as drive C. Good so far. Windows XP copies setup files to the new partion and reboots. OSS does not come up, instead I get a Windows screen that say "autochk program not found - skipping autocheck" Then a blue screen appears and it reboots. So, I reactivate OSS and now there is a second Windows XP icon. I double click it hoping the setup will continue, however the screen goes blank with the cursor flashing in the upper left of the screen... it is locked up. I reboot to OSS and select Disk Director. The Disk Director screen comes up briefly, then reboots to OSS again. So I select Disk Director again.. this time it comes up. It shows my new partion as active and the original partition as hidden. It looks correct, yet I try the procedure many times with the same result. Am I doing something wrong?
