Convert the disk to MBR using diskpart, or delete all partitions from the disk and repartition (and when other disks are connected, disconnect them).
Why do I need to convert to MBR partition? If my laptop had Windows 8 installed with GPT partition and UEFI boot when it was purchased, then there must be a way to clean install Windows 10 x64 on same configuration. Right?
Alrighty, it's fixed finally with changing boot/partition configurations. I think the mistake I was making while creating USB flash drive for Windows was a couple of default settings.
Because it was not reading my USB drive. But I got it now. I read somewhere that UEFI doesn't read NTFS file format so I changed it to FAT and it worked.
