Cannot boot from CD even if bios boot order is OK

0

I have to boot from cd on a HP Pavillon g6.

It has Windows 7 factory installed but the guy forgot his password. So I made this Windows 7 recovery cd from another Windows 7 to try to do something.

The CD boot fine on the laptop I used to create it, but not on the pavillon.

I did go into the BIOS to adjust the boot order, but it didn't help. I can hear the CD turning at boot time but the computer won't boot from it.

The BIOS is a InsydeH20 version F.21

I googled and everywhere it tells to disable secure boot in the bios. The problem is that I don't have this option in the BIOS.

Does anyone have an idea of what is happening here? Or better, yet what I should try from now?

NB:

For now I am using the external display connected via HDMI, because the screen is broken (a new one is on it's way), but I don't think it's relevant for my problem.

[update] I did a factory reset so I now don't really need to boot from CD. But this question is still relevant for me : I want to understand what is the problem so I can face it differently next time (factory reset will not always be an option)

Did this guy, you're talking about, forget BIOS password or local account password? – alljamin – 2017-01-19T03:21:47.357

Can you verify if it's UEFI or BIOS? – dark_st3alth – 2017-01-19T05:17:03.663

I can acess BIOS without password. He just forgot his windows passwords. I don't know if it's UEFI but I think it's not. Otherwise I would expect to see more options in the BIOS – baraber – 2017-01-19T14:37:48.313

UEFI is different from BIOS, and can cause boot disks to "not work".

Verify if the pre-boot system is UEFI or BIOS. If it's UEFI, there will be a "legacy" or "BIOS Compatibility" mode which after enabling, should allow you to boot to the live CD/DVD. The boot disk you are attempting to use probably doesn't support UEFI.

Likewise, you can confirm this on your own system, to see if it is either UEFI/BIOS and has a "legacy" option enabled.

I'm not sure how to determine if it's UEFI. But in the BIOS which I access pressing f10 at boot time, I have no "Legacy mode" nor "Secure Boot". So I presumed it was not UEFI. – baraber – 2017-01-19T14:40:37.077
