My lifebook ah512 says no bootable device
Thank you for your question, my name is ***** ***** I look forward to assisting you.
Please note, click on Reply to Expert to reply to me, a rating is only needed when we are finished.
If it says no bootable device then it means its not detecting the hard drive at all, which will usually point the a crashed hard disk.
Can you power off the Lifebook, then power it on and repeatedly press (not hold) the F2 and delete keys.
This will get you into the Bios, then go to Boot Order and make sure the hard disk is set as the first device.
then save this and tell me if it then starts please.

gone straight to bootable device not found

Thanks Deb, it confirms the problem
It is the hard drive that has faulted.
The lifebook cannot detect the hard drive which is the bootable device it is searching for and this is why it will error out and fail to start.
I am really sorry about this and you are going to have to return the lifebook to have the hard drive replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
Thank you
