I remember a solution to the rog motherboard that I encountered when I installed the computer, but the hard disk was recognized but there was no boot disk.
Applicable conditions: The hard disk can be successfully identified in the nvme sata information in the storage information, but there is no hard disk in the startup options.
Solution 1:
First restore the BIOS default value, F5, press enter, F10, press enter.
Solution 2:
After the solution 1 is determined to be invalid, check whether the BIOS, BOOT option, CSM, Launch CSM are ENABLED, if not set to ENABLED, F10, press Enter.
Generally, the above two steps can solve 90% of such problems.
If it is not resolved, please use solution 3: find the BOOT option, after entering
HARD DRIVE BBS PRIOROTIES , check if you can find the corresponding boot device in BOOT OPTION #1, if yes, select the device you need as the first boot
item, F10 to save.
If the above three methods are ineffective, it is recommended to find after-sales to troubleshoot or replace the motherboard.
