Maybe you need to boot up into rescue mode and reinstall grub? I've had to do that a few times during fresh installs lately. -----Original Message----- From: P.

On my desktop computer, everything appears to have gone smoothly, although I have had little time to experiment. Getting back into my old system, F23, gave me some problems, since osprober (?) generated menu items for linux/initrd and not linux16/initrd16. Luckily, I was able to find that out pretty easily. The laptop computer has turned into a major nightmare. Everything installed just fine. I powered off and removed the disc and wanted to try it out. Instead of the grub menu, I got a message "TPM error 1" and the grub rescue prompt. I went into the BIOS of the laptop and randomly tried every possible variant of enabled, disabled, factory defaults and so on that I could stumble upon, but I am unable to get anything but the TPM error and the grub rescue prompt. How do I get rid of the TMP problem and boot into the new system? -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: http://lists.fedoraproject.org/admin/lists/test@xxxxxxxxxxxxxxxxxxxxxxx
