My Win10 bootloader ate grub so whenever I attempted to boot Debian, it would skip to Windows. So I reinstalled grub. Now Windows won't boot and the partition is locked in hybrid mode. :/

I just wanted to play Fallout occasionally... :(
Never happens on my other computer

Also I'm bracing for the overwhelming slap of stupidity when I call their tech support and have to explain what Debian is >.<

> "...I reinstalled grub. Now Windows won't boot..."

What's wrong with this? Sounds like Debian is working perfectly to me :D

@Gophyr lel. It is. But I can't get Fallout 3 to run on Wine. So...

Maybe you just wrote to a single ESP? In that case you gotta make another ESP and reinstall the windows bootloader.

@Natrocx I've tried win10 startup repair. It fails instantly.

Hybrid mode is unnecessary, even on a Mac. Modern Windows and Linux support EFI/GPT natively.

I'm referring to hybrid shutdown, where the hard drive is unusable, unrecoverable, and unfixable until the next biot, which now can't happen.

@chadd17 Can you boot off a Windows install USB/DVD and run chkdsk?

@d4ng3r0u5 I can. I'll let you know how that goes.

I have both Grub and the Windows bootloader on a single ESP on my machine. Doesn't the Bios give you a choice of which to boot? Also, you might like to try rEFInd instead of Grub for ease of use.

@CurtisMJ yes but on this machine, windows bootloader is now broken. What's the deal with rEFInd?

@d4ng3r0u5 chkdsk C:
Windows has scanned the file system and found no problems.

...which gave me the idea to try to use the file in cmd instead of bash, and tada! I can see my files. That'd be nice if I had anything to backup. Any way to fix boot from here?

@chadd17 rEFInd is an alternative boot manager. It's quite good at auto-detection is all. I was just thinking it might be able to boot Windows if installed from Debian, but if Windows is truly broken it might not help anyway.
Edit: The rEFInd site has instructions on reinstalling the Windows bootloader

cmd --> C:/> DIR
just fine
Reset PC, keep files
The drive is locked. Unlock and try again.
If I knew my license key I'd just wipe and reinstall...

Boot Manager error message

@chadd17 if your laptop (?) is post-windows 8(.1), your license key is embedded in your bios, reinstalling win10 will automagically use the proper key

@Tobyvw if you are 100% sure, I'll do it, but attempting a reinstall so far has scared me off by prompting for a license key. Also this thing's warranty may still be good since I got it this week.

If it came with Windows 8 or later the key is most certainly embedded if you cannot find a sticker with a key.

But of course. Reinstalling will probably remove the old files you saved there
