How do I recover my boot device?

Anonymous

During a migration of my PC into a new case, there were issues with the move (assume my mistake) and the device went to the BIOS. Motherboard is a 2024 z790 ASUS TUF Gaming. In the BIOS, I mistakenly clicked to enable Rapid Storage Technology and then Save/Exit and did not realize it until too late. Now the PC can no longer identify a bootable device. The only boot options listed were ipv4 and ipv6 ethernet options. I changed the RST back and the storage devices are seen there. However, none indicate as a boot device s an option

First, is all data on all drives gone? Or is only the boot drive wiped from this?

Second, if not gone, how do I recover the drives to get a bootable PC again?

Would a recovery effort to restore the Master Boot Record or something undo my mistake?

Thank you for the help in advance

    Hi, I am Dave, I will help you with this.

    None of the steps you performed would have deleted the data from the drives.

    1

    In the Boot Priority list, do you see 'Windows Boot Manager' as an option to set as the primary boot device?

    If you do, set that as the primary boot device to see if oyu an boot up Windows on your system

    2

    If that did not resolve the problem, in BIOS, you can toggle on/off the CSM Support setting to toggle between UEFI BIOS mode and Legacy BIOS mode, try each to see if you can get the system drive to boot up.

    Thanks Dave! Your #2 simple solution was it. I could swear I had done that but must not have had the right sequence at some point. I rarely enter/change BIOS settings so it is a great relief to know knowledgeable people like you are out there to help. Thank you.
