    Hi, my computer recently failed to start, I tried to system restore and that also failed, so I decided to run my install disk so as I could enter the command prompt and clean and partition my hard drive using diskpart... The computer allowed me to do this, which is why I don't think my hardrive is dead, but since exiting command prompt and restarting computer, I'm now just getting black screen that says no boot device found, please insert bootable disc and press any key to continue... Does anyone have any suggestions as to how I can resolve this please... And if so bear in mind I'm not very tech savvy so need it in dummies terms please lol

    In order to help you, you need to post ALL of your exact system specs; ie exact mb, exact cpu, exact pw supply, etc, etc. If this is a big box system ie dell, hp, whatever, post the exact make and model# If you have a service tag, post that as well.

    It does sound like your hd has failed or possibly a failed cable, loose pw connector, etc. You can test the drive with the drive mfg's diagnostic. You download this from whomever mfg the drive. Since your system will not boot from the hd, you need the dos or boot version [it runs from bootable media]

    Additional details would be useful.

    Ensure power and data cables to/from the hard/optical drives and motherboard are properly inserted.

    As a precaution, you could check in BIOS that the boot sequence is optical drive first, then the hard drive next. To gain access to BIOS menu, press either F8, or F2, or DEL key (key to be pressed depends on BIOS version; check your motherboard manual for details). Make changes to boot sequence if necessary, save and exit. Reboot.

    Unless I'm misunderstanding the situation, when the drive was "cleaned", did this mean the drive (boot partition) data was wiped or reformatted? If so, the operating system may have been deleted, and that's why there may be boot issues. In this case the operating system will have to be reinstalled in the boot partition of the drive via the operating system installation disk. Install operating system optical disk in optical drive. Reboot. Follow on screen prompts to reinstall operating system in the boot partition of the hard drive.

    In post #1 you stated you used diskpart to clean/partition your hd. Exactly what did you do? If you used the "clean" cmd from diskpart, that removes all partitioning info ie the disk is now blank and as such, of course it will not boot.
