Windows 11 upgrade issue
Hi,
Currently, Windows 10 is installed on Legacy Boot Mode on my laptop.
I want to upgrade to Windows 11 without fresh installation, So tried to start it from Windows 11 update Assistance tool and it is giving an error. Microsoft PC Helth Check tool shows "This PC must Support Secure Boot", then from BIOS I disabled Legacy boot and enabled Secure Boot. But after that, it is not loading the OS. Giving an error Hard Drive not Found.
Can anyone suggest on this?
Regards,
Vishwanath
- This is an expected condition because when you enable secure boot, your hard drive should be in GPT partition style. In legacy boot, it is in MBR partition style.
You can easily fix this by converting MBR to GPT using this documentation:
