@ Lucap I've just test the iso modified keeping grub_platform command and removing the part that evaluates the variable and I get the same results as when I removed both: 32 seconds to togo and 1 minute 22 seconds to language selector. I wasn't noticed what was changing on partitions layout with all this tweaks but in this last experiment I see with Gnome disks that the usb drive with the modified iso has a MBR partition table instead the GPT partition table of the original ISO. In fact, before all of this experiments on the first post of this report I link a post where give instructions for changing the partition table from GPT to MBR. According to fdisk the partition table resulting from the modified ISO is:
Orden (m para obtener ayuda): p Disco /dev/sdd: 3,79 GiB, 4048551936 bytes, 7907328 sectores Disk model: Transcend 4GB Unidades: sectores de 1 * 512 = 512 bytes Tamaño de sector (lógico/físico): 512 bytes / 512 bytes Tamaño de E/S (mínimo/óptimo): 512 bytes / 512 bytes Tipo de etiqueta de disco: dos Identificador del disco: 0x00000000 Dispositivo Inicio Comienzo Final Sectores Tamaño Id Tipo /dev/sdd1 * 64 5496567 5496504 2,6G 83 Linux /dev/sdd2 5496568 5506607 10040 4,9M ef EFI (FAT-12/16/32) /dev/sdd3 5509120 7907327 2398208 1,1G 83 Linux The last one is a writable partition and was preceding of a empty space of 1.3 MB according with gnome-disks Furthermore, the first partition is marked as bootable So I confirm your results. I'm going to trying the last instructions of Thomas. I don't have too much technical skills either but I'm going to try my luck. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1922342 Title: HIrsute live session takes ages to boot on BIOS systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1922342/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
