Alpha RC2: Cannot get past "Booting in ...... in 0 seconds" screen on iMac 2011 (booting from USB)
Last modified: 2013-04-17 07:28:47 EDT
Description of problem:
On a 2011 i5 iMac, if you boot TC5 Live image via USB you can get into the Grub2 menu, but it never goes past the "Booting Fedora 18 alpah tc5....in 0 seconds" screen.
Version-Release number of selected component (if applicable):
Could be a kernel issue maybe...
Proposed NTH for alpha.
Discussed at 2012-09-10 QA meeting, acting as an NTH review meeting. Agreed we need far more detail to evaluate this. What Mac model exactly (in the conventional MacMini,2,1 format)? Booted how (boot camp, 'native' EFI, what?) How was the USB stick written? Also, please re-test with TC6 or TC7/RC1 when it's released, as there have been improvements in the EFI boot stuff, and use the latest livecd-tools from updates-testing.
Tried RC2, did not even get the Grub splash, only command line. I just copied the files on a bootable USB stick, should that not be enough?
I think the machine is an iMac 2011, 2 (I do not really get the mac naming format).
Tried with liveusb-creator and livecd updates from updates testing. Still stuck on boot screen, booted nice on other machine.
What happens when you simply boot the imac with the rc2 livecd ?
Discussed at 2012-09-12 NTH review meeting. We agreed there is still not enough data to evaluate this.
Andreas, we're still not sure you're using a 'correct' method for creating the USB stick. "I just copied the files on a bootable USB stick" doesn't sound like it was right. liveusb-creator is a proper tool, but we're not sure it actually works for UEFI boots at present.
The two methods we are sure should work for UEFI boots are:
dd if=filename.iso of=/dev/sdX
livecd-iso-to-disk --format --reset-mbr --efi filename.iso /dev/sdX1
you need to pass --efi when using litd; it doesn't make the stick EFI bootable by default.
Could you please try with one of those two methods and report back? Thanks.
livecd-iso-to-disk --format --reset-mbr --efi filename.iso /dev/sdb
with RC3 works!
Great job everyone!
