Dear Maintainer,

Ever since Jessie got the upgrade to grub 2.00, my laptop with grub-efi
installed does NOT automatically boot into debian the "first" time. What
I mean by the first time is the first boot after turning on the
computer.

The boot hangs very early at the 'loading initial ramdisk' stage.

Rebooting the computer using the key combination Ctrl+Alt+Del makes it
reboot and then the grub booting sequences proceeds accordingly

I don't know what's wrong here. Worked perfectly well before grub2

The computer is a gaming laptop, ASUS G55VW.

Dear Maintainer

I have the same problem, each time I try to boot into debian it stuck at
"loading initial ramdisk", then I go with Ctrl+Alt+Del and it boot properly.

I have this problem on an Intel NUC D54250WYK.
I have an SSD mSATA with just an EFI partition and a Btrfs partition.
Debian testing amd64 without DE (just a script to run XBMC).

Regards

The hanging can be caused by many things.

1. Try adding "nomodeset" to the boot command line. It may be a graphics driver issue - notable with Nvidia based systems and the nouveau default driver.
2. If you have multiple graphics cards (more relevent to desktop) such as an on-board and an PCIe based card it is important to make sure that either you have monitors plugged into both outputs or that the on-board is completely disabled - setting the bios selection to use PCIe first is not enough as there is an issue during boot where the graphics driver will swap to using the on-board graphics just after the loading ramdisk message.
3. Have you added kernal debug options to the boot command? Such as verbose, debug and ignore_loglevel? The last one is particularly useful and shows how far the boot actually got. Some info here: https://wiki.archlinux.org/index.php/boot_debugging although arch linux its still relevent.

Hi all!

The bug is still present in stable jessie. I installed debian 8.0 in a
clean VirtualBox environment. Did update-grub && update-initramfs -u The
next boot stops early in boot stage with the following line:

"loading initial ramdisk"

I found out that deactivating USB completely in that virtual machine
solves the problem.

Update: Strange thing, the next reboot succeeded even with USB enabled
again...

Dear all,

I have the same problem to boot my macbook pro retina Early 2015. When
I try to boot the system it gets stuck in the "loading initial
ramdisk" stage. Then, it reboots automatically, and sometimes it
passes this stage or get in a reboot loop. I used the guide in [0] to
boot in efi mode.

However, If I just boot directly by using the Startup Manager[1] the
"loading initial ramdisk" problem disappears.

I have tried the following to solve the problem without success:

1) nomodeset in the grub menu.
2) update-grub; update-grub2.
3) update-initramfs -u
4) Reinstall all /boot/efi from scratch.

However, as already stated, launching the grub menu from the Startup
Manager works just fine.
