  • Did you verify your download? That's where I'd start with this error. Tip: If you download it via torrent, it'll automatically verify it for you.

  • Hello I checked the checksum and everything is ok. I think there are some settings in the BIOS but my knowledge is not sufficient.

    Hello It all started working when I disconnected the ST500LM012 HN-M500MBB JMicron Generic SCSI Disk Device from my computer. I have no idea why this error occurs with this drive, regardless of whether the drive was connected at the CD site or externally via USB. Now I have a Toshiba inside my laptop and this problem is not there. Also thanks and the problem has been solved.

1 Answer 1


The problem described may occur when old models of drives are connected to the computer. In my case, after disconnecting, the problem does not occur.
