Stuck in upgrade from Tiger to Snow Leopard

iMac OS X 10.4 Intel Core 2 Duo

Bought the box version of Snow Leopard (like a good Mac citizen). Inserted OS disk. Clicked on install Snow Leopard. Now I just have the Mac version of the hour glass. If I do a cold reboot (complete power off), it tries to reboot but gets stuck at the wait icon.

Any thoughts?

No abnormal noises. When I first started the process, Finder correctly identified the DVD. The problem now is that I cannot get it to reboot to a normal state. So I cannot even eject the DVD. It is just hung at the revolving busy icon. If I turn off the machine, unplug it, then power up, it goes right back to the white Apple screen with the busy icon.

Everything was working fine before this......as far as I know. I will reboot to disk utility and report back. Thanks.

Boot up from your system installation disk by holding down the "C" key. Go to the second screen pull down menu to Utilities -> Disk Utility and format or repair the drive (if you have nothing to save on the old drive, I would format it and give it one partition.) If you do the drive I would select the "write zeros" option to map out any bad blocks. Was the Mac booting OK before you started this?

Power cycled while holding down "C" key, but realized that I have no way to remove the Snow Leopard DVD. Anyway, no results just goes back to the white screen with busy icon......sigh. Beginning to wonder why I even attempted the u/g. My IPhone 4 wouldn't sync from my Mac, but syncs fine from my Windows machine.

I wanted the Snow Leopard disk in to boot from. To eject a disk just hold down the mouse button when starting up. I'm trying to think of why you're having problems loading. How much RAM do you have and did you have 10 GB of free hard drive space?

I have plenty of free HD space (>200G). How do I check free RAM? Sorry for the newbie questions, I don't use this machine as much as the kids do.

Boot it from anything and go under the Apple in the upper left hand corner to about this Mac. It should tell you there, if not hit the more info button and go to memory

OK, rebooted and ran disk utility. Some errors were fixed. Retried upgrade and it was successful. Thanks for all your help. I learned some useful Mac tricks in the process. BTW, as far as I know, there is no embedded utility for determining realtime memory usage, but there are some available off the shelf (e.g. iStat?).

What noise does the drive make while the Mac is stuck there? Might as well be a defective or dirty DVD, or faulty drive. Is it correctly recognized by the OS once booted? Do you have any problem booting/reading/burning other DVDs?

I can't stress that point enough - the internal slot in drives of all Macs are not worth a grain of salt. Do yourself a favour and get an external drive USB or Firewire. A Intel Mac is easily booted from USB, with PowerPC Macs it is a bit more tricky and Firewire is to be preferred.

What i meant is that i had a lot of trouble with all the combo and superdrives and just consider them as "not very good".
