Snow cannot be used to upgrade Tiger.
The boxed set comes with Leopard and Snow.

First off, I learned that it's a REALLY GREAT IDEA to run Disk Utility, then Repair Permissions and Verify Disk (also Repair Disk if needed) before trying any sort of OS upgrade.
Also if possible try to avoid starting it and taking off for a couple hours - I did same, and I think my MB went to sleep and borked things...
At 45 mins left, it suddenly rebooted and I got the apple with pinwheel for at least 5 mins. I figured it was "hung" and hard powered off. This is where the problems started.
4) Failed twice in a row "Invalid inode map cannot repair" or something similar.
4.5) At this point you might try simply quitting the installer. It will prompt for the boot disk to use. Select your hard disk to stop it from booting into CD. You might get the pinwheel for a long time (say 15 minutes) while it does the fsck during bootup but you might get back to your system where you can try the install again.
6) Command prompt (on macbooks your main partition is typically /dev/disk0s1, this will vary depending on your disk setup tho):
fsck -fy /dev/disk0s1
then (note the following command could be dangerous ... use at own risk as a last resort, you could lose data, you have been warned):
fsck_hfs -pry /dev/disk0s1
(this did find a bunch of errors and tried to correct them)
...I don't know if anything here was even necessary though, and even
after all this I still could not mount the drive and fsck still gave
"bad superblock" errors.
8) At this point I was astonished to see everything come up OK!

Make sure you have a backup but do not erase the drive. Run the Snow Leopard installer as described in the instructions furnished with it & make sure you are selecting the startup volume in the displayed volumes choices. If you then get this message, restart from the Snow Leopard installer disc (or just click its "Utilities" button), & launch its copy of Disk Utility. Run the "Repair Disk" step, followed by the "Repair Permissions" one. Then try the Snow Leopard installer again.
If you get the same error message again, or any message from Disk Utility indicating problems with the startup volume volume, report them here.
