I had a sudden mental malfunction last week and installed Windows 8 preview without reading trough the part that you cannot get rid of it. I got HP pavilion g6, don't know what version of Windows 7 I had, but anyways I backed up all my files on another computer and tried to use HP system recovery to reset it to factory state, but instead managed to reset Windows 8 and wiped the remains of Windows 7. Tried again with F11 during start up, that doesn't work. So I found that another solution would be to use EasyBCD on some files located at recovery drive, except it appears to be empty, although it is supposed to contain 13GB of something. So I found that yet another solution would be to set recovery drive as active. That resulted in the computer not being able to find OS. So I burned system rescue cd to USB drive and used Super Grub to find that I supposedly have two Windows Vistas - number one is corrupt (so I suppose could be remains of Windows 7) number two is Windows 8. And when I start computer it boots the corrupt one. So I got two issues here - is there some way to make it boot Windows 8 without having to use linux for workaround? Secondly, more importantly, neosmart sells Windows 7 recovery cd, but it says it won't install new Windows, so will it work if recovery files are, indeed, corrupt?
