Hi all, I have a MacBook Pro that I purchased right before Snow Leopard came out. I purchased Snow Leopard today, and the install failed miserably. I was waiting for the install to complete, but decided to go to dinner when the estimated time went past zero and started counting into negative minutes. When I returned it said the install failed, I clicked 'retry' and then it took forever to find my HD, and when it did it said the HD couldn't be modified. One thing led to another and I powered down the system and now I can only get to the white booting screen with the Apple logo but the status logo just keeps spinning and spinning and nothing happens. I have my original start-up CD, but the Snow Leopard CD is in there and I can't get it out. The only weird thing about my computer before trying to install Snow Leopard is that I had a file I couldn't delete. It was an openoffice file (tried Trash It), and figured the new OS may take care of it. If I hold Shift+cmd+v during startup the last line says "[HCIController][configurepm] power parent ready after 1 tries disk0s2: I/O error. disk0s2: I/O error. (keeps repeating the longer it tries to boot - about 1x every 2 min) I truly appreciate any ideas - thanks!
