I installed fedora 18 on an unpartioned section of my hard drive and it simply won't boot saying 'ext4 fs incompabilities' and it simply shows the fedora logo then a permanent black screen... during install it gave a ' kmod 04 something' error.
Now the f+++ed up thing is that after installing fedora 18 I lost the ability to load a live session into ram, both ubuntu toram or fedora live_session fail to load the system into ram (this was working fine before the install) and worse still is that I lost sound in windows 7 and ubuntu....
I can't figure out what's going on, does fedora 18 tries to flash the soundcard firmware? why would it stop functioning in other OS's???
How can I delete the Grub live bootloader that I installed with fedora 18 (I already deleted the partitions)
If I flash my BIOS again and format my hard drive will everything return to normal?
