Hi everyone. I have searched the threads and can find no solution to the above.
I have a Z370 Aorus Ultra gaming with Win 10 64bit and an Intel i5-8400 LGA 1151 processor. All was fine after having to replace the MB with this after a Win10 upgrade caused issues with my previous MB. ( there is a post about it somewhere without replies) Without any explanation this current MB suddenly would not boot . Both drives are SATA along with a DVD SATA.
The boot failed with an error message -no such device ( a string of characters) followed by a prompt
I reviewed the BIOS and the boot drive did not appear in the boot list. However, if I use the F12 option it appears and if I select it the system boots and all is fine. All attempt to include the correct drive in the boot order fails. Can anyone offer help as to what GRUB rescue means and how to get it booting properly.
