Thank you for taking the time to report this problem, and help making Ubuntu better.
QUESTION: What OS & release are you writing the thumb-drive with? (ie. details of the GNOME-DISKS and StartUp Disk Creator, as I wonder if it's how you write your ISO to media. I am writing various ISOs (mainly Lubuntu, but other flavors too and on occasion Ubuntu) to thumb-drive and booting it on various BIOS only devices (hp dc7700, dc7900, dell 745, 755, 780 etc). I personally use `mkusb` to write my media, but regularly also just use `dd`.., but I'm usually writing media on a hirsute box (hence the request for details on what OS/release you use to write your ISO) I note your `lshw` shows an "i5-3570" CPU which is more modern than any BIOS only box I use (my boxes are c2d (t6570, u9400, e6600, e6850, e8300..), c2q-q9400 etc) so maybe it's a quirk on your hardware, compared to the older hp, dell, lenovo.. I test with. -- 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 does not work 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
