I have been trying to install Windows 7 on my Mac Mini recently, but due to various hard drive errors and failures I radically decided to Wipe my hard drive, completely erase it in the recovery disk utility and restore from a backup. When I tried to access the backup drive again, it started OS Lion's online recovery mode (takes about 1 1/2 hours to start). I then restored my hard drive and restarted my computer. Half an hour later it is STILL on the grey screen with an apple logo and spinning 'worm' and getting very hot. Rinse and repeat, but this time just install Lion. Did it again. Restarted, it worked but it was all strange, it was a mix of different backups from different times. Restore from backup AGAIN, same problem. What is going on?
