Windows boot failure

Question

Basically I have both windows 10 and windows 11 installed on my laptop. Windows 10 in HDD (Came with laptop while purchasing) and windows 11 in SSD (after a year of use I externally installed SSD because my laptop has extra slot for SSD). Now in normal use I was using windows 11 but from last 2-3 days while putting my laptop on charging after 4-5 minutes on charging laptop windows crashes and shows Blue screen having error code UNEXPECTED_STORE_EXCEPTION. Today same thing happened again and after automatically restarting laptop from blue screen it boots with windows 10 from HDD and I tried to boot with Windows 11 from BIOS Setup Utility but it does not shows the Windows 11 option for booting in Boot Options -> UEFI Boot Order -> OS Boot Manager of BIOS setup. So by default it is booting windows 10. That's the problem I am facing.

Hello

The UNEXPECTED_STORE_EXCEPTION error in Windows 11 can be caused by several factors, including hardware problems, corrupt system files, or outdated drivers. Here are some steps you can try to resolve the issue:

Check Hardware Connections: Ensure that your SSD is properly connected and there are no loose connections. Sometimes, a loose connection can cause such errors.

Update Drivers: Outdated drivers, especially for your hard drive and graphics card, can cause this error. Make sure all your drivers are up to date. You can do this through the Device Manager or by visiting the manufacturer’s website.

Run System File Checker (SFC) and Check Disk (CHKDSK):

Open Command Prompt as an administrator.

Run sfc /scannow to check for and repair corrupted system files.

Run chkdsk /f /r to check for and fix any disk errors.

BIOS Settings: Since your BIOS is not showing the Windows 11 boot option, you might need to reset your BIOS settings to default or update your BIOS firmware. Be cautious with BIOS updates and follow the manufacturer’s instructions carefully.

Check SSD Health: Use a tool like CrystalDiskInfo to check the health of your SSD. A failing SSD can cause such errors.
