Hello Subham Das,

Thanks for reaching out here in the Microsoft Answers Community.

Since you have mentioned that you have already backed up your system and performed a system reset, please note that resetting reuses system files, so if there is an issue with system files, the issue will persist after resetting.

Based on the situation, I recommend performing a clean system reinstallation, which erases everything from the hard drive and starts you from scratch. Please make sure that you have copied all the personal data to external storage (like USB sticks, external hard drives, and memory cards) to prevent data loss.

To do so, please prepare a USB stick that is at least 8 GB in size (do not use the one with your backups, since it will be erased), then download and run the Windows 11 Media Creation Tool on another computer. Follow the instructions, and when selecting the media type, please select "USB stick", and then select the drive letter the USB stick is in.

After creating the installation media, please plug it into your computer, and boot from it in UEFI mode. The exact procedure differs among motherboard manufacturers, so please refer to the user manual for details.

Also, please check the following BIOS options, as some motherboards use RAID mode by default which needs specific storage drivers that may not be compatible with the latest version of Windows:

SATA controller mode: Change to AHCI mode (even if there is no such disks)

NVMe RAID mode: Turn off

Intel Rapid Storage Technologies: Turn off

If you are going to modify BIOS Settings, please back up all your personal files first to ensure you do not lose data.

After booting, please select "Install now". Follow the instructions, and when selecting the installation type, select "Custom: Install Windows only". On the next installation screen, please delete all the partitions (including EFI, reserved, and recovery ones) in your system disk. Select the unallocated space and select "Next". The installer will partition your system disk automatically.

Please refer to the "Clean install of Windows 11 using installation media" section of this support article for further details.

Disclaimer: At this point, we have exhausted all troubleshooting and I recommend that we try to perform a clean install to get your computer back into a working condition. Please ensure that you backup any important data, including Documents, Pictures, Videos, and more.

Thanks for your patience and understanding.
