I recently replaced my HDD(removed it from laptop) with samsung's M2 NVME SSD(now laptop only has SSD).
I install windows in it. But now when i go for installing ubuntu20 it shows to disable Intel RST(Laptop had an intel optane memory which got replaced with new SSD ).I use to run ubuntu on HDD but there was no such error back then.
Also few suggested to change the controller from SATA to AHCI but hp laptop doesn't seem to have that.
Well and I dont want care if the windows is completely gone i just want to use ubuntu.
I'm sorry, but HP only warranties their PCs for usage with the OS that comes preinstalled.
IF you replace that with a Linux distro, or add a Linux distro, then you assume full responsibility for maintaining that -- including solving any problems with booting the other OS and/or installing the other OS.
Modern PCs with UEFI, instead of the older BIOS, are especially difficult to install because you have to go into the UEFI settings and make several changes before you can even boot from a USB stick -- and we are unable to assist in that work.
Your best bet for support now is to contact the support forum of the distro you are using.
