Hi, Tanishk, I am Jeronimo, Thanks for reaching out! I'm an Independent Advisor and a Microsoft user like you.
When you see the EFI PXE Network Boot Failed message, your system is trying to boot from a network (PXE) because it can’t detect a valid local boot device. This can happen if the system intermittently loses connection to your SSD or if the BIOS boot order has reverted to a default network boot setting.
Going to BIOS > More Settings > Boot > PXE Boot to LAN > Disabled could prevent the message from appearing.
The Kernel Data Inpage error generally means Windows encountered a problem reading data from your drive into memory. This can be due to bad sectors on the drive, a failing SSD, loose connections, or even faulty RAM. The “Critical System Failed” message (which sometimes appears with other stop codes) might be another manifestation of underlying hardware issues or corrupted drivers.
The fact that the boot drive isn’t consistently detected could point to a loose connection or an intermittent fault in the SSD. With professional help consider checking for dust or a loose connector internally.
Although you’ve run SFC and chkdsk, consider using the SSD manufacturer’s diagnostic tools to check for subtle failures or bad sectors. Intermittent connectivity issues can sometimes bypass a basic chkdsk scan.
