I am trying to reinstall OS X 10.4 Tiger on an Emac 1ghz that I've bought for the purpose of getting to know Macs. The install is an "Archive and Install". The reason for doing so is, the previous owner left a lot of his personal data and other items (including sensitive material) on the system. I thought the best way was to re-install as I was tired of constantly finding more of his stuff all the time, obviously, if I was experienced on Macs I would have no problems sorting this out. He had told me that the disks for Tiger were included but it turns out they are Panther disks so I have bought some Tiger disks and believe (hope) I have bought the correct ones. He had actually used borrowed disks to install Tiger. He also had told me a program called Sound Studio 3 was on the system and in answer to my question confirmed that it was part of Tiger! That was lost when I removed his profile. Needless to say he and I won't be doing any further business. Perhaps I might have been better to have done an "Erase and Install" but, I didn't, and now I have an install that has been stall for several hours and I don't know how to proceed from here. Can I abort and start again and if yes, how? The screen currently shows:- Installing Mac OS X then in the progress pane:- Installing 2005 World Book Writing files: 99% Completed Time Remaining: About 25 minutes as mentioned earlier it has been at this point for several hours. If this situation is retrievable I will appreciate advice as to whether I should do a complete re-format and install, retrieve the achieved install (how?), or? I have searched the forums and not found an answer, have tried to be clear and accurate, have, hopefully used correct Mac terminology and I wish to say that, as a new to Mac member I appreciate the time and effort by others to help people like myself. Thanks.
