Inaccessible boot device
My computer is an Optiplex 755 with Windows 10.
After replacing the power source, I am now in the automatic repair loop, with an "inaccessible boot device" message. I cannot access the keyboard or mouse to act on the bluescreen message ("restart" and "advanced options" are options - but I can't select either one).
I can access keyboard to get to setup and boot menu
Otherwise I can't do anything.
No Events found!

If the system worked fine before replacing the PSU then there has to be a connection between the new PSU and this problem. Are you sure the data cable and power cable for the hard drive are firmly connected to the hard drive and motherboard? If you can get to the boot menu, run system diagnostics to be sure the hard drive has not failed. If the drive passes then with F12 select the hard drive to boot from (it may be Windows Boot Manager). If that works then in the BIOS the boot order may be wrong.

Thanks for info.
I ran diagnostics yesterday. No issues.
Boot sequence shows item 1 onboard SATA hard drive - not present.
2-4 seem ok.
Item 5 - onboard network controller not present.
No hard drive ... I'll re-check that connection.
