Hi Basically, with my Leopard installation i have a problem where it fails to boot up likely due to a previous unexpected power cut. From googling the issue it seems like the only solution anyone has had to the same problem is to re-install. However I've lost my Leopard system discs. I booted into my Bootcamp Windows installation and installed the latest drivers from the Snow Leopard disc which i recently purchased (and came today) This gave me the option to read files (and presumably copy) from the mac partition but no delete function. I have two problems here: 1. I only have 2.61GB free on the mac partition, Snow Leopard requires at least 5GB. Since I can't boot into OS X and Windows can't write to the partition i can't delete any files. 2. My mac won't boot the Snow Leopard DVD for installation. I hold C while booting and it has no effect. It does however run the Hardware test if i hold D while booting. I have an external drive i could probaly make enough room on to back up my entire osx partition for a totally clean re-install. However this requires some sort of access to the drive/write capabilities. Maybe something like bootable linux? And any idea why my disc won't boot? (even if i had enough space for a install...that would be a bit pointless if i can't get the disc to boot) Thanks for any help with this!
