hi, i own this: https://support.hp.com/in-en/product/hp-pavilion-dv6-6c00-quad-edition-entertainment-notebook-pc-series/5214356/model/5214358?sku=A1U59AV it has BIOS (not UEFI). i followed the instructions to create KRD using rufus on my USB flash drive. but rufus-3.11p recognizes the ISO as meant for UEFI only and even if i set the partition scheme as “MBR”, there is no option to change the target system from “UEFI (non-CSM)”; i chose “YES” to download the grub 2.02 but the resulting USB stick cannot be booted by my BIOS. i tried the steps using rufus-3.5p and rufus-3.6p which automatically show option of the target system as “BIOS or UEFI”. but, attempting to boot from this flash drive resulted in the following: GRUB loading Welcome to GRUB the only way to escape from this was CTRL+ALT+DEL. after this i tried many such softwares, like Win32 Disk Imager, SARDU pro, ventoy, YUMI std, UUI, unetbootin, xboot, in both DD mode and ISO mode but none of them can boot the USB. the only change is that my USB stick has worn out. but i desperately need to scan my laptop with KRD-18. can someone tell me the right software to use and the right settings pertaining to my BIOS? thanks in advance.
