My Toshiba netbook fell down and hasn't booted again. When I start Windows 7 it immediately says: Windows failed to start... Status: 0xc0000225 Info: The boot selection failed because a required device is inaccessible. After that, there are a few things to consider: There's a Linux distro Linkat which is also installed in the computer. It starts normally without any problem and it doesn't seem to display any errors when it boots. I restored all computer OSs with clonezilla and some images provided by the manufacturer, and it's done nothing. I have already checked the basic components of the PC (RAM, Hard Disk, WLAN Card) are pluged in and working. My impression is that's all about some broken part inside, though the Linux OS starts normally. Does anyone know a way I can fix this or at least any software for identifying the problem at all?
