I am sorry if this subject has been covered, I did not see a previous thread. I have XP pro installed on a disk that is partitioned into (4) slots, CDEF On the C-drive is XPpro on D is data on E is empty for the win2000 install on F is large programs. I cannot seem to be able to boot from the win2000 disk it shows all partitions are unformatted and damaged If anyone can help I would appreciate it. I am using Disk Director/w OS selector and True Image. maybe I was not clear on my problem. I have a functioning computer. I partitioned it with Disk Director and made an image of the C-drive with True image. I would like to install win2000 pro on a separate parttion (E) XPpro is on C, I have another partition for data (D) I have tried to boot from the setup disk of win2000 after it loads the files it reads the disk and I get a message saying that the partitions are damaged/ and or unformatted and it does not matter what partiton I choose to install to it says that windows will have to reformat the entire C drive to install I do not want to continue for fear that I will reformat my XPpro install and that is my only OS Please any advice from anyone?
