On few days , my friend came to me , he had trouble with his notebook after failure on UBuntu OS Instalation, the partition of its hardisk unable to open , read or to save some stuff, then I try to detect the problem . Firslty chek the partion if it is can be open by clicking on the drive manualy :
E:
But its seemly cann't open so I try the second step :
Open the Disk Management
right click one of the partition that can not be opened and then format it so its ready to use
