Windows 10: Error Codes 0xc0000001 and 0xc0000098 – Unable to boot any longer [duplicate]

I’m at my wits end and have had no luck finding a resource/discussion that could help me fix my Windows 10 installation, MBR or whatever is causing it.

One moment my PC was booting fine, the next startup it went into Recovery Environment. Then after trying to let it fix it, which it obviously couldn’t, it then started showed me alternating error codes for each attempted boot: 0xc0000001 and 0xc0000098.

I’ve never had any other OS than Windows on this machine. It’s the “latest” Windows 10 LTSC Enterprise btw. The only way I can access command prompt right now is through a USB with Windows Installation Media on it. I’ve so far tried fixing this with Boot Repair Disk and Sergei Strelec (EaseUS Partition Master). They both claim to succeed but nothing changes.

Bootrec /FixBoot gives the error “Access is denied”

I have already tried bcdboot dozens of times with different volume letters, but I might have mixed them up at this point. I’m so lost now.

I will now list the relevant Volumes I see in Diskpart:

**Volume ### Ltr Label Fs Type Size Status Info **

Volume 4 F System Rese NTFS Partition 50 MB Healthy
Volume 5 G __________ NTFS Partition 476 GB Healthy
Volume 6 ____________ FAT32 Partition 100 MB Healthy Hidden
Volume 7 ____________ NTFS Partition 501 MB Healthy Hidden

(Terribly sorry about the formatting, I don’t know how to make it pretty)

I’m no expert, be gentle. If you got instructions for me, feel free to include everything so I don’t have to guess.

Edit 1: Forgot to add it’s a desktop with MSI B450 Tomahawk Max motherboard, 3700x CPU and boot drive is 500 GB NVMe SSD
