Hi @sushilord,
My first idea is a bad BIOS/UEFI setting.
You can:
- try legacy mode vs UEFI (setting in BIOS/UEFI and also boot menu entries)
- (re)read the install guide for checking if you miss a step or a setting
- read the troubleshootings help
- (re)read the system-requirements
- search a similar hardware in HCL
- try a R4.1 alpha iso
- wait next 4.10.4rcX with a 5.y default kernel
I hope that one of the above lines will help you.
