HP Laptop cannot boot into BIOS OS

Posted on 2016-11-22
Last Modified: 2016-11-28

I have an HP laptop (please see specs attached).

I tried to reload Windows OS on it (Windows 7 x64). I also have changed the booting in the BIOS (F10 to access Bios) to priority internal cd/dvd write so that the post goes to optical drive first (where i have my os 7 dvd on).

Anyways, it still did not work. I have also changed the Security Boot to "Disabled" and re "Enabled" but still the machine always boot to the internal optical drive boot loader.

Any reason why this machine cannot load the windows 7 os loader (cd/dvd)??? and it keeps skipping it to load the internal hdd os?

Please advise.

First, check that the W7 DVD is bootable on another system.  If it is, then ...

If the laptop BIOS is set to boot from DVD first, then it should.  However, sometimes other options affect this.  Check for BIOS boot options such as "Boot removable media first" or "Boot optical media first".  If these are present and  unenabled, the system may boot from the hard drive regardless.

Failing this, remove the hard drive from the system, take it to another system, hook it up there and erase it using a product such as Darik's Boot and Nuke.  Before using DBAN, disconnect all other hard drives from the system!

After erasing the hard drive, the laptop will have no choice but to boot from the DVD drive.

Are you ABSOLUTELY SURE that the internal drive is a CD/DVD, and not just a CDROM drive?
If so, after you boot and hit escape, try hitting F9 instead of F10, and then select to boot from the optical drive.

@akahan - please see my screenshot (attached) of my bios boot...let me know what you think?

My boot os are dvds and i am suspecting that this particular hp model doesnt support dvd but rather cd.

What is your advise further?

the optical drive seems to be a dvd burnerbut if you want to be sure - look in device manager for the model
it can also be the drive is bad - so test if you can boot from other bootable media : cd, DVD

so i have also installed a new mechanical hd (removed the previous one) with no os on it. I tried via a cd/dvd usb writer and boot from there but still skipping to the os boot loader.

any reason why it keeps on skipping and ignoring my priority booting (ie: internal cd/dvd, usb cd writer). I have also pressed F9 to try to boot to internal optical drive but i cannot see the partitions nor the drive displayed there (just empty).

any reasons why?

perhaps i will need to load the os onto the drive via another laptop and then remove it once installation completes and mount once again to this HP machine? With this option, i know it will work. But any reasons why i am having no success with my first troubleshoot as mentioned above?

It has been a VERY long time since HP shipped a CD drive with any of their systems instead of a DVD drive -- I do NOT think there's ANY chance that's the issue.

You indicated you had "...  I have also changed the Security Boot to "Disabled" and re "Enabled"  ..." ==> You need to turn OFF Secure Boot  AND  enable legacy support to allow booting from your Windows 7 install media.    If you've been trying to boot with Secure Boot enabled, that explains why you can't do it -- just make these changes and it should boot with no problem.

Disabling secure boot may automatically enable legacy support => but generally it will be an option in the BIOS settings for boot options.

@garycase and all - please refer to my attachments for the screenshots and description as i explained during the process.

My OS installation cannot pass through as it stuck in with the logo at displayed in step 5

It looks like that this laptop as been disabled to accept other booting method other than requiring the original HP Discs that come with this particular laptop. In my opinion, the other local computer supplier might have done this so they can only re-service the machine. I am not sure but i am suspecting why this wont even work.

Can you advise what is the best solution to this? Do i need to visit HP and download the Installation Disc for all their HP laptop or what???

In addition to disabling Secure Boot, you need to clear all Secure Boot keys.

Also, post a picture of the options shown under the Main and Security tabs.    There may be something there you also need to change.

Okay, there aren't any BIOS passwords set (I was concerned this might be an issue).

So clear all the Secure Boot keys; then see if you can boot to your Windows 7 disk.

If not, show the current state of the Configuration page in the BIOS after you've done that (same picture as "Step 2" above.

also note - that i have done all i know and still wont boot to my system disk. even trying to boot to a third party linux WinPE boot disc - still wont boot from that.

But good news - it is booting now and enable me via a factory OS (Win 8.1) - but for the Windows 7 and other OS...wont work as i have already tried.

So i have fixed this via Windows 8.1 boot loader since the OS factory is Win 8.1

Thanks guys for the input.

Please do let me know why some latest laptop (like this particular drive) will not accept any other non factory os (ie: Windows 7, 10, etc).

Thanks again.

The problem is there's no "legacy" boot mode setting in the BIOS.   It will only boot to boot media that can do a UEFI boot.

I thought that after you'd disabled Secure Boot and deleted all those keys it might have presented a legacy option -- but apparently that's not the case.    It may also allow that if you change the "Platform Key" setting => not sure what the options are for this, but that was what I would have had you look at next if you didn't already have it working.

But the key thing is that HP hasn't provided any options to allow a legacy boot.
