I'm trying to set up secure boot in my BIOS, but the first step requires converting my MBR boot drive to GPT. However, when I attempt to shrink my C drive by 550 MB to create space for the EFI system partition, I keep getting an error saying the volume might be corrupted. It suggests running chkdsk to fix this issue, but here's the catch: I can't run chkdsk because the C drive is in use by Windows. My PC always shows a 'scanning and repairing drive' message at startup, which has been the case for a while now, and I never got around to running chkdsk until today. When I try to schedule chkdsk after rebooting, it goes through the motions but nothing changes, and I'm still unable to shrink the partition. I also looked for access to cmd from Advanced Startup to run chkdsk from a separate Windows version, but that option doesn't appear. Any help would be appreciated!

You might want to consider using Clonezilla to create an image of your drive first. It has a repair mode that could help restore the drive before you try shrinking it again. Check out their website for instructions!
Have you tried running chkdsk /f? It should allow you to schedule it for the next reboot. Just be careful, though—people have been bricking their PCs lately with these updates if they're not careful!
Yeah, I’ve tried that, but the daily scanning and repairing just keeps looping. I don’t know if this is directly related to chkdsk, since I never attempted to run it before recently.
