All in one 27-r060no - Boot device not found

HP Recommended
All in one 27-r060no
Microsoft Windows 10 (64-bit)



I have a 13 month (one month past warranty, yay!) old All in one Desktop. The computer has two disks a 256GB M.2 SSD and a 1TB regular spinning disk. The OS is installed on the M.2 drive.


The computer hung and I had to perform a cold reboot by pressing the power button.


On first boot I recevied the message "Boot device not found, Hard Disk - (3F0). I have done the disk checks that passed. I have checked the 1TB-disk in another computer and it works fine.


I guess that the M.2-drive didn´t like the somewhat brutal shutdown. I can see it in the BIOS listed as a 1GB M.2 drive, should be 256GB... I have also tried running a new Windows installation but it can´t even find a 256GB partition only a "Drive 1 Unallocated space, 1023MB" apart from the 1TB Drive 0.


Has anyone experienced anything like this? Im worried that the motherboard has been damaged. Best case seems to be that only the M.2-drive has to be replaced.

From your description, it certainly sounds like the SSD got clobbered.  There would not be one 256GB partition, instead, there would be 2-3, maybe 4 partitions: an ESP, Windows OS, Recovery, and (maybe) HP_TOOLS -- but Windows should take up most of the 256GB.

What HP Recovery Media does is reformat the entire drive, recreate the original partitions, and then repopulate them.  So, if all that happened is the partition records got corrupted, this would likely work.

But there are two caveats here ...

First, you would most likely have to purchase the Recovery Media, especially since your PC is out of warranty, and there is no guarantee that would even work.

Second, if it were mine, I would find out how to open the case and disconnect the 1TB spinner (HDD) -- to ensure that does not get touched in any way by the restoration.  Sorry, but I have no information on how to do that.

Wish I had better news -- maybe someone else can provide information on how to open the case without damaging it.


Here is contact information for HP Customer Service --who you would contact to order the Recovery Media:

Turns out it was only the M.2 drive that was failed so Im looking at a 100$ problem instead of buying a new computer/motherboard.


A friend of mine came over with another M.2 drive with Win10 on it and the OS booted fine when we put it in my computer.


For anyone else reading this I can say that it´s really easy to open the case with some mild force. Just watch a youtube video or two on how to do it. To access the M2 drive you have to remove 6-7 screws to lift a metal casing that sits over the motherboard. No special screws or anything.
