rufus tool problem

You should delete all partitions not just C:. If you are using the ISO file created by Microsoft Media Creation Tool, then I would advise against using Rufus to create the USB flash drive. After install is done, you can turn secure boot back on. If you just used the diskpart method to create the USB flash drive, or just let the media creation tool create it directly, you would not need to turn secure boot off at all.

as I wanted 1809 version only and it was greater than 4gb rufus created with ntfs then I had to select in bios other os instead of uefi now all my partitions on ssd are ntfs now I chose again uefi os in bios so what difference all this made to my pc? I had been using uefi since the beginning it is not uefi anymore now? also if I again use iso with media creation tool and make gpt again will other partitions like D and E will not work?

We can't offer you valid advice because we don't know the layout of your computer's disk drive(s). We need to see a screenshot of disk management posted per the instructions here:

These are the settings in Rufus that should be used:

Attachment 243885

This will create a flash drive that is bootable ONLY in UEFI mode. Once the computer is booted from the flash drive, the resulting Windows 10 installation is guaranteed to be UEFI and the installed SSD will be GPT. If @tushar4544 wants to keep D: and E: drives, then after selecting the custom install option there will be a list of drives and partition. Select each partition that is in front of the D: and E: data partitions and delete them. There is probably going to be 4 to delete. Recovery Partition, small MSR partition, EFI System Partition, and the old Windows C: partition. The drive should be left with one large unallocated space followed by 2 data partitions (for D and E drives).

Highlight the unallocated space and click next to finish the install. When the computer reboots, the flash drive may need to be pulled out to keep the computer from rebooting back into Windows setup on the flash drive. After the install is complete, Secure Boot can be turned back on in UEFI settings.

Yes, they are on a GPT disk and your computer is booting in UEFI mode.

How did you confirm its gpt

Disk management shows 5 primary partitions. The drive must be GPT for that to be possible.
