Thank you Tobias and other folks and really sorry for delayed reply on this.
This is what I did:- 1. Updated motherboard BIOS version to latest one. 2. Verified ISO file should be same as downloaded one, it was corrupted so corrected later. By doing so, I was able to see Qubes 4.2.0 RC4 installation UI, but was not able to resolve issue of Installation source, so I decided to use Rufus made USB installation media, for this, when I tried to make USB installation media for "Qubes-R4.2.0-rc4-x86_64.iso" by rufus, *I was seeing only UEFI (non CSM) option as follows:-See attachment "4.2.0V.png"* *but with current stable version of QUBE OS "Qubes-R4.1.2-x86_64.iso", this issue was not replicable:- See attachment "4.1V.png"* To fix this issue, CSM support should be enabled in my motherboard BIOS, but I don't have any external graphics card and and as per " https://www.asus.com/support/FAQ/1045467":- *Intel 500 and the latest series of chipsets do not support VBIOS display, so the integrated display does not support legacy boot, use a graphics card that supports VBIOS to enable CSM.* so this means, in Qube OS 4.2.0 iso file, we are forcing to enable CSM, but in 4.1 version , we were not. I think, We should not force need of CSM support for QUBE OS 4.2.0 version too. I hope, this helps to understand cause of issue. Please let me know, if any correction or any information on this please.

Have you checked that the image on the USB medium matches the ISO image you have downloaded?
