Booting safe mode glitches GRUB out

[Deleted member 398281]

Hi y'all,

Last night I wanted to boot Windows into safe mode. I currently have a dual-boot setup with Windows 7 and Ubuntu, with Win7 as most-used OS. So I chose my GRUB entry and repeatedly pressed F8 as soon as I pressed enter. What previously worked before, does now result in the standard GRUB "loading-screen," the purple screen with a white line around it, and my fan stopped spinning, indicating my laptop isn't doing anything at all. To fix it, I had to stop pressing F8 and press enter twice. I could hear my fan blowing again, and Windows started loading the bootloader. When I pressed F8 just when it started loading, it resulted in a screen, seen below:

As the typical, purple color suggests, I think this is a GRUB screen. I don't want to find another way to access safe mode, just how to access it through the normal way of booting it. This doesn't happen with normal booting. I am able to boot into Ubuntu to change GRUB settings.

Do you have a specific resolution set in your GRUB configuration? You may need to boot it in plain VESA mode.

Not that I know of. However, I do have GRUB customizer installed. I'll check my settings when I am home.

Ok, so you won't believe this, but you'll have to.
When I came home last night, I immediately tried to start Ubuntu and take a look. (using GRUB ofc) For some reason, it boots into busybox, with an initramfs command line. I think that means that there was a failure when mounting the partition, but I'm not sure. Anyway, when executing any command, there's a kernel panic following with an immediate reboot. At this point, my system is practically useless, unless Win7. I already tried booting a Live CD, but for some reason, even that fails. Unfortunately there is no known way for me of editing GRUB using Windows. I literally can't do anything at this point, except entering my primary OS.
Do you know some way of entering Ubuntu without the normal method or a Live CD?

I don't have a solution, but GRUB customizer is most likely the cause (it's a piece of shit that ends up making a mess of GRUB's settings.)

You'll have to use a Live CD/USB to fix it. There's no way around that.

As I can't boot a Live CD, I'll probably copy my files to my Windows partition with some tools, and then delete my Linux partitions. I'll look further when Windows boots normally again...

Why can't you boot the Live CD? Is there not an option to do so from your computers BIOS menu?
