I have a 24 digit error code

[Nick_berger09]

I deleted my operating system by accident and i get a 24 digit error code when i ran the hard disk scan. I have windows 10 on a flash drive but it originally had windows 8. How do i install when it says no bootable device found?

Hi::

If your notebook reported a 24 character failure code for the short or long DST, you will need to install a new hard drive and reinstall the operating system.

Below is the link to the service manual, where you can find the hard drive removal and replacement procedure.

You may want to consider replacing the 2.5" mechanical hard drive with a better performing 2.5" SSD.

After you replace the drive, you can use your bootable W10 installation flash drive to reinstall W10.

If you are asked to enter a product key during the installation process, select the 'I don't have a product key' option.
