Thanks for your reply. However neither with Platform ID 80x86 and the eltorito.img nor with UEFI and the efi.img I'm able to boot from the created image. I also tried checking and unchecking the "Patch Boot Information Table" - it won't boot. Any more information I could give you to pinpoint the culprit? Edit: I also tried the "Extract Boot Image" option with the virtual drive, created by mounting the image through Windows (10) Edit 2: If it makes any difference, I'm using Hyper-V for the VM, though I doubt, it does, since the original image works just fine. I believe Hyper-V uses EFI.
Hi there! Since the search only pointed to this topic and I couldn't reply to it, I'm creating a new one. What's new on the front? 10 years later and I've run into a similar problem. I'm trying to rebuild/remaster the k3os-amd64.iso I've copied the contents of the ISO into folder "x:\k3os-amd64" tried extracting with 7-zip, as well as mounting via Windows and copying from the virtual drive edited some files unrelated to grub or boot started up ImgBurn selected "Create image file from files/folders" added folder "x:\k3os-amd64\" via "Browse for a folder..." switched to the tab "Advanced/Bootable Disc" activated "Make Image Bootable" selected Boot Image "x:\k3os-amd64\boot\grub\i386-pc\eltorito.img" switched Platform ID to "UEFI" checked "Patch Boot Information Table" clicked "Build" The resulting ISO file wouldn't let my k3os vm boot, while the original, unmodified k3os-amd64.iso works without problems. Are there any options I'm missing, am I using it wrong or won't this ever get fixed? Thanks a lot for ImgBurn and in advance for any help.
