Before You Choose a Repair Method

Step 1. Create or open bootable media, start the problem PC from it, and load Qiling Disk Master in the recovery environment.

Step 2. Select the Windows disk. Check whether it is GPT or MBR and whether the PC uses UEFI or Legacy BIOS.

Method 1: Fix Boot for Startup File Errors

Step 1. Choose Fix Boot when Windows is still on the disk but Windows Boot Manager, BCD, or startup files may be damaged.

Step 2. Confirm the selected Windows disk, click Proceed, restart the PC, and set Windows Boot Manager as the first boot option for UEFI systems.

Method 2: Rebuild MBR for Legacy BIOS/MBR Errors

Step 1. Choose Rebuild MBR only when the disk is MBR and the PC starts in Legacy BIOS mode. It is not the first repair for GPT/UEFI Windows installations.

Step 2. Select the proper MBR type, preview the operation, and click Proceed. If the problem remains, check disk health, boot order, BCD entries, and storage drivers.

FAQ

Should I make changes before backing up? If the disk is readable and the files matter, back up first. Repairs, formatting, conversion, and cloning can change boot records or partition data.

When should I use Windows built-in tools? Use Settings, Disk Management, Startup Repair, CHKDSK, SFC, DISM, or account recovery first when the issue is simple and the risk is low.

When does Qiling help? Use Qiling tools when you need a clearer disk map, a bootable recovery environment, backup before repair, partition preview, disk cloning, or controlled password recovery on an authorized PC.

Conclusion

Boot error 0xc0000098 is usually repairable when the Windows partition is intact. Fix boot files first, and investigate disk health if the error returns.
