I tested the Ubuntu Vivid daily 32-bit mini.iso (dated feb 9) in my IBM Thinkpad T42 with Pentium M, and it works for me too with this double boot option.
I clicked tab to get to the boot line. I edited the boot line from > linux vga=788 initrd=initrd.gz -- quiet to > linux vga=788 initrd=initrd.gz forcepae -- quiet forcepae and the installation of a minimal text system worked for me. Thank you very much for helping us to solve this problem, Chris :-) -o- Is this new usage of boot options general? 1. The entry before -- means that it will be used by the live system / the installer 2. The entry after -- means that it will be carried to and used by the installed system -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1422675 Title: No installable kernel was found in the defined APT sources To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1422675/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
