Problem With Disabling Secure Boot

@srsalim1918 

Not clear from your post what is the nature of the current problem ...

 

Since your PC came preloaded with Win10, if it is less than a year old, that Windows came preinstalled in UEFI mode, with GPT formatting used on the drive, by default.

 

When you disabled Secure Boot to install a non-Windows OS, it might have then changed the boot to Legacy mode -- for the installation.  But when you rebooted, it was probably back in UEFI mode, and it would then NOT be able to see the other OS.

 

With modern UEFI'/GPT PCs, there is a LOT of work needed to successfully install a non-Windows OS without messing up the PC.

 

Your best bet, since HP does not provide non-Windows OS support, if to contact the support forum for the OS you installed and see what they suggest.
