so i tried reinstalling my hitachi prius laptop using win7 bootable cd.pressing f2 then change the boot priority to cd/dvd. it went ok and almost completed the installation but it suddenly stop and the installation fails and it automatically prompt me to the manufacturers logo. i turn the pc off and reboot hoping it will repeat the installation process. but this time it hangs up to the manufacturers logo only. i tried pressing f2 but i can no longer enter the bios setup. a friend told me to remove the cmos battery for 10 min and i did but still not working. please help me what to do. i would really appreciate your help. thank u so much.
