Hi Vinodh933,
Your post does not say which laptop or Windows version you are using, so I will explain the most common meaning of "conventional mode" on an HP notebook. If you mean the older Legacy BIOS boot mode (also called conventional or CSM boot mode), instead of the modern UEFI mode, here is how to enable it and what to know before you do it:
1. Shut the laptop down completely.
2. Turn it on and immediately press Esc repeatedly, then press F10 to open BIOS Setup.
3. Go to Advanced, then Boot Options (on some models it is under System Configuration, then Boot Options), and find Legacy Support. Set it to Enabled.
4. Go to the Secure Boot setting (usually under Security, or Advanced, then Secure Boot Configuration) and set Secure Boot to Disabled, because Secure Boot cannot be used with Legacy boot.
5. Press F10 to save all changes and exit. The laptop will restart in Legacy boot mode.
Two important warnings:
- Windows 11 requires UEFI and Secure Boot. If your laptop has Windows 11, enabling Legacy boot can stop Windows from starting. Only enable Legacy mode if you need it for an older operating system or a specific installation.
- On many newer HP notebooks the Legacy Support option no longer exists, because the BIOS only supports UEFI. If you cannot find Legacy Support in your BIOS, your model does not offer it.
If you meant something else by "conventional mode", for example a conventional (offline) Windows installation or a setting you saw in another program, please reply with the exact name of the program or screen where you saw "conventional mode" and what you are trying to install, and I can give you the exact steps for that.
