[qubes-users] Issue with "Qubes release 4.2.0-rc3" | USB Installation Media not detected in UEFI BIOS

Hi Team,

I put more efforts on this and fixed issue at my end itself.

If you see rufus download page “https://rufus.ie/en/”. here a bug has been fixed in Rufus version 4.2, below are fixed issues/enhancements in 4.2 version of Rufus (highlighted one was the issue with me as I was using Rufus 3.x version):-

  • Version 4.2 (2023.07.26)
    • Add detection and warning for UEFI revoked bootloaders (including ones revoked through SkuSiPolicy.p7b)
    • Add ZIP64 support, to extract .zip images that are larger than 4 GB
    • Add saving and restoring current drive to/from compressed VHDX image
    • Add saving and restoring current drive to/from compressed FFU (Full Flash Update) image [EXPERIMENTAL]
    • Fix a crash when trying to open Windows ISOs, with the MinGW compiled x86 32-bit version
    • Fix an issue where ISOs that contain a boot image with an ‘EFI’ label are not detected as bootable
    • Increase the ISO → ESP limit for Debian 12 netinst images
    • Ensure that the main partition size is aligned to the cluster size
      so now I have installed Qube OS 4.2.0 RC4 successfully on my machine.

in nut shell, following steps helped me to get fix of this issue:-

  1. Using latest version of Rufus (4.2 or above)
  2. Updating BIOS to its latest version
  3. Verification and usage of corrected Qube OS ISO file

Thanks and Regards
Rahul
