Can I restore Window 10 after erasing drive

I just bought a laptop with Windows 10 installed. I was trying to convert it to a dual-boot Linux Windows computer, but ran into trouble with the UEFI boot mechanism for Windows which was not working to recognize the Linux DVD. Anyway, I ended up destroying the Windows 10 partition(s). Is there any way to get WIN10 back? I have no Windows DVD or repair disk.

Just go to another computer and get an media creation tool for Windows 10 and download the iso and then either burn it to a DVD or better create a bootable USB...
If everything goes well when you first connect to Internet you copy will get activated (during the installation process when it asks for a key just skip...unless your laptop carries one)

Just to confirm what you're asking ...

Did you want the original Windows 10 partition back, or did you want to reload W10 from scratch?

Not sure how to answer. The original Windows 10 partition is gone. In order to boot the Linux DVD I had to change to "Legacy BIOS", not UEFI. That let the Linux DVD boot, but the installation process wiped out the original partitions before I realized it. The whole drive is now Linux and Linux swap. No NTFS.

I'm not so interested in the Linux/Windows dual-boot ability at this point. I'd like to get the computer back to Windows 10 only and worry about dual-boot later, much later!

John Tsioumpris: Will try your idea as soon as I get near a WIN10 box.

If the original recovery partition is erased then you have an only option - to download the installation media and install the same version of Windows which was on this laptop.
Or you can ask the manufacturer for a recovery DVD with Windows backup on it.
Usually in UEFI systems the activation key is saved in BIOS so Windows should find it there once installed.

I tried John Tsioumpris' suggestion, but the recovery partition of the computer is also gone (thanks to me). A local expert at a computer store said WIN10 could still be recovered, but would require re-creating the partition and some other time consuming procedures, so I decided to forget about it. Fortunately, it was a new laptop and I was able to return it to the store without problem. Thanks for the help. Next time, I'll do some research on dual-booting Linux and WIN10 with UEFI before acting rashly.

btw John Tsioumpris, your link on creating a media disk was in Greek, which, as they say, "was Greek to me!". No worries, I was able to get such a boot in and try it.
