[qubes-users] Re: HCL - Dell Inspiron 5570 (P75F, P75F001)

My, Dell Inspiron 15 5570 has i5 8250, 12GB DDR RAM , 1TB SATA HDD. I have created a bootable Qubes 4.2.0 with dd command in Ubuntu and trying to boot my Dell Inspiron with it. However it is failing to boot and restarting and falling back to Ubuntu 23.10. Should I try to boot in legacy BIOS mode ? Currently I am trying to boot in UEFI mode with Secure Boot and PTT (TPM) enabled. To boot in Legacy BIOS mode I have to disable Secure Boot and PTT(TPM). Please advice.
