Upon consulting osx daily website i erased a a 4gb file in private folder which is something to do with RAM and now i can,t boot up. I,ve tried to do numerous types of boots like holding c and trying to reinstall my original cd with snow leopard on, but,
If i try d utility the areas i need like verify or repair etc are dimmed out. If i tryand reinstall it asks me which startup disk i,d like to boot from and there are no disks to choose from. Please help. P.s. im not fussed about wiping the existing m lion os and programs and starting from scratch if that what it takes.
iMac, OS X Mountain Lion
