Trying to install Ubuntu. But it's repeating same problem broG'day @madhu786 and welcome to linux.org
From your screenshots, you appear to be attempting to install Parrot to a 32 GB USB stick instead of to your hard drive alongside Windows.
That would be on /dev/sda not /dev/sdb
You should start again from scratch and direct the install to the correct place.
If this is your first experience with Linux, I should tell you that Distros such as Kali and Parrot are not for beginners, they are for security industry experts.
You should consider trying Ubuntu or Linux Mint first, and getting a couple of years experience before trying the others.
