Powered down my ASUS PN50 miniPC before heading out for the weekend. When I tried to boot, I encountered a 0xc0000034 error. After inspecting everything, I saw in DiskPart that the boot drive isn't C: anymore... The partitions were listed as C: (STORAGE), D: (BOOT), and then a FAT32 system partition. It seems the BIOS battery might have failed, resetting the boot order? I'm not sure how to fix this or restore the correct drive order. Please let me know. Thanks!

I meant Disk Management, not cmd diskpart.

It seems you're having trouble starting diskmgmt from a boot disk. Let me know if you'd like help troubleshooting!

Usually, the drive that starts Windows and has Windows installed is the C drive. The smaller boot area might actually be on another drive.

Diskpart shows three disks in total. I think this command displays physical disks, though it seems someone might be mistaken. Disk 0 is the 931G "Storage" disk, and Disk 1 is the 476G "boot" disk. Oddly enough, the BIOS doesn't present multiple boot options, only one.

Right.
Only the drive with the boot partition would be listed.
The real Windows can run on a completely different physical drive.
This occurs when you install the OS on more than one physical drive.
The 'boot partition' ends up on another drive.
Disregarding drive letters, does the system actually start?

Just to the point it causes the 0xc0000034 error...so no, not really

During my research into the error, I discovered the MS page detailing what seemed to be damaged boot sector or corrupted boot files. When trying to apply the tools and following the manual steps to resolve it, nothing resolved. This led me to observe that the C:/D: paths were swapped from their original state before the shutdown. It made me question whether the repair failed because of an incorrect boot drive or another issue. I wondered if correcting the swap in C:/D: could potentially fix the problem.
