It just means that there is not enough capacity on the concerned disk. If this message is shown, you can copy no more files to the disk. In this case, you need to remove unwanted files and programs or move them to another disk or media. This way, you can create space for new files and programs.
A Disk Boot Fail means that the disk you normally start your computer from is not working. The computer can be started from the System Disk but that system disk will wear out so you will have no boot disk and no way of repairing the boot disk. Time to look for a new boot disk or better a brand new computer
The best way, I think to answer that is to define what a computer (or in this case the motherboard of the computer) needs to find or identify a hard disk. A hard disk needs a power source, a connector to attach it to the motherboard, and a controller to talk to the microprocessor of the computer. If any of these things fail the hard disk will not function and the computer will not recognize it. In general when you see the message "hard disk not found" its because the computer can't recognize the hard disk. This can be from a bad cable (that connects the hard disk to the motherboard), no power to the hard disk, or a failed controller. In my experience, its usually a bad cable but there are times when the hard disk itself will fail. Generally, hard disk cables are far more fragile than hard disks.
After the disk has been read goto the windows sign at the bottom left of the screen and click it, goto 'my computer' or 'computer' and click it, finally click where it says DVD and the disk will start playing.
It means the computer can read it and says there isn't a disc like "I can't read it"
You would have to get your "Install" disk that came with your computer and do the steps it says when you put it in. If you lost your Install disk then may want to call/go to the store you bought your computer from for further instructions.
Computers do read DVD-Rs but if your computer doesn't read DVD-Rs you may not have a DVD Drive. To make sure you have one, Look on the drive. If it says Compact Disk, that means CDs only. If it says Compact Disk and DVD R/RW you cab view and burn DVDs
you have too many pictures! upload or delete some because your phone doesn't have space for anymore. Or get a memory card.
your computer mite have a virus. :\ your computer mite have a virus. :\
It could be that your computer is referring to itself when it says "this device."
As with all systems, your disk is probably dirty. Clean it and try again.
Reinstall Itunes
it either needs windows reinstalling or a new hard disk, take it to someone who is a computer person!
