Due to ransomware i need to format my disk and install OS again. There is no cd drive . How could I possibly do this?

Thank you.

Hi

A lot depends on what you got.  Like another PC to make a Recovery Media.

There are rescue disks   TDDSK and  KRD18 , there are OS's      like W10.

Which could/should fit onto a USB.

#####

From 2016 onwards there is a possible recovery option via the cloud...
HP Consumer PCs - Using the HP Cloud Recovery Tool (Windows 7 & 10)
https://support.hp.com/us-en/document/c06162205
OR
This First part only works when a valid Recovery Partition is enabled.

If it displays an error message then move onto the Second part,
OR if you have data you wish to try and save using the XCOPY command.
Then create your own Repair/Recovery/Rebuild/Re-install media or buy a set from HP.

Turn off the computer.

Disconnect all connected devices and cables, Media Drives, USB drives, printers, & faxes.
Remove media from internal drives, and remove any recently added internal hardware.
Do not disconnect the monitor, keyboard, mouse, or power cord.

Turn on the computer and repeatedly press the F11 key, about once every second,
until the Choose an option screen is displayed, and then continue.

On the Choose an Option screen, click Troubleshoot, and work your way through the screens.

Second Part:-
This may require another PC. Find and Download your .iso from…
W10 should activate automagically from the embedded licence key.

Expand/Extract/Burn the iso Image onto a DVD/USB as needed.
Microsoft’s Creator Tool will make the required DVD or USB.

The RansomWare may be a ROOTKIT and a simple re-format will not remove it.

If in doubt please ask.
